ROI & Performance Calculators

5 Calculators

Prove marketing value and optimize campaign profitability. Calculate return on ad spend, overall ROI, conversion rates, and break-even thresholds to make confident budget decisions.

🚀

ROAS Calculator

Most Popular
ROAS calculator return on ad spend formula good ROAS for ecommerce

The Problem: You're pouring money into advertising but can't clearly answer the most important question: for every dollar spent, how much revenue are you generating? Without ROAS visibility, you're making budget decisions in the dark and potentially scaling unprofitable campaigns.

The Solution: Our ROAS calculator instantly reveals your Return on Ad Spend by comparing advertising revenue to ad costs. Know exactly which campaigns, ad groups, or channels deliver the highest returns so you can confidently scale winners and cut losers.

How It Works

ROAS (Return on Ad Spend) measures the revenue generated for every dollar spent on advertising. A ROAS of 4:1 means you earn $4 in revenue for every $1 in ad spend. This metric is crucial for paid advertising profitability, campaign scaling decisions, and budget allocation across channels.

ROAS = Revenue from Ads ÷ Cost of Ads (or as ratio, e.g., 4:1)

Key Benefits

  • Prove advertising profitability to stakeholders
  • Identify highest-performing campaigns to scale
  • Compare efficiency across ad platforms
  • Make confident budget allocation decisions

👤 Who Needs This

  • E-commerce marketers tracking ad-driven revenue
  • Performance marketing managers
  • CMOs reporting to the board on ad efficiency
  • Agencies proving value to clients

💡 Pro Tip: Target ROAS varies by business model. E-commerce with 30% margins needs 3:1+ ROAS to break even. SaaS with high LTV can accept 1:1 initial ROAS if customers stay. Use our Break-Even ROAS calculator to find your specific profitability threshold.

💰

ROI Calculator

Essential
marketing ROI calculator return on investment formula prove marketing value

The Problem: Marketing is constantly asked to prove its value, but calculating true return on investment across all channels and campaigns feels overwhelming. You need a clear, defensible number to justify budgets, yet accounting for all costs and revenues accurately requires complex spreadsheet work.

The Solution: Our marketing ROI calculator simplifies profitability measurement by calculating the percentage return on your total marketing investment. Account for all costs—advertising, tools, team time—and compare against revenue generated to demonstrate clear business impact.

How It Works

Marketing ROI measures the profit generated from marketing investments relative to the cost of those investments. Unlike ROAS (which focuses on ad spend), ROI includes all marketing costs: advertising, software, salaries, agency fees, and overhead. The result is expressed as a percentage showing return above your investment.

ROI = ((Revenue - Marketing Cost) ÷ Marketing Cost) × 100%

Key Benefits

  • Justify marketing budgets to leadership
  • Compare marketing efficiency across periods
  • Identify most profitable marketing channels
  • Make data-driven investment decisions

👤 Who Needs This

  • Marketing directors presenting to executives
  • CMOs defending budget proposals
  • Business owners evaluating marketing spend
  • Finance teams assessing marketing profitability

💡 Pro Tip: A positive ROI (any percentage above 0%) means you're making money. Most businesses target 5:1 ROI (400% return) as a healthy benchmark. Remember to include all costs: if you exclude agency fees or tool subscriptions, your ROI looks artificially high.

⚖️

Break-Even ROAS Calculator

break-even ROAS calculator minimum ROAS for profit calculate target ROAS

The Problem: You know your ROAS numbers, but you're not sure what ROAS you actually need to be profitable. Different products have different margins, and without knowing your break-even point, you might be scaling campaigns that look good but actually lose money once all costs are counted.

The Solution: Our Break-Even ROAS calculator determines the minimum return on ad spend required to cover your costs and achieve profitability. Input your product costs, overhead, and margins to discover the exact ROAS threshold where campaigns stop losing money and start generating profit.

How It Works

Break-even ROAS depends on your profit margins. If your gross margin is 25%, you need a 4:1 ROAS just to break even (1 ÷ 0.25 = 4). The calculator factors in product costs, shipping, overhead, and desired profit margin to give you a precise target ROAS for every campaign.

Break-Even ROAS = 1 ÷ Profit Margin (as decimal)

Key Benefits

  • Set realistic, profitable ROAS targets
  • Stop scaling unprofitable campaigns
  • Price products with advertising costs in mind
  • Create margin-based campaign strategies

👤 Who Needs This

  • E-commerce brands with varied product margins
  • DTC businesses calculating advertising budgets
  • Marketing analysts setting campaign targets
  • Product managers optimizing pricing strategy

💡 Pro Tip: Calculate break-even ROAS for each product category separately. A 50% margin item breaks even at 2:1 ROAS, while a 20% margin item needs 5:1. This insight helps you prioritize advertising high-margin products and avoid wasting spend on low-margin items.

🎯

Conversion Rate Calculator

Essential
conversion rate calculator e-commerce conversion rate formula landing page conversion rate

The Problem: You're driving thousands of visitors to your website, but too few take action. Whether it's purchases, signups, or leads, you suspect your conversion rate is below par—but without measuring it accurately and comparing to benchmarks, you can't prioritize optimization efforts.

The Solution: Our conversion rate calculator instantly measures the percentage of visitors who complete your desired goal. Track e-commerce purchases, lead form submissions, newsletter signups, or any other conversion to identify bottlenecks and optimize your customer journey.

How It Works

Conversion rate is the percentage of visitors who complete a desired action. If 1,000 people visit your landing page and 50 submit a form, your conversion rate is 5%. This fundamental metric affects CAC, ROAS, and overall marketing efficiency. Even small improvements compound dramatically at scale.

Conversion Rate = (Conversions ÷ Total Visitors) × 100%

Key Benefits

  • Identify landing page and funnel bottlenecks
  • Benchmark performance against industry standards
  • Prioritize CRO (conversion rate optimization) efforts
  • Calculate traffic needed to hit revenue goals

👤 Who Needs This

  • CRO specialists optimizing funnels
  • E-commerce managers improving checkout flow
  • Lead generation marketers testing landing pages
  • Growth hackers measuring experiment results

💡 Pro Tip: E-commerce average is 2-3%. B2B landing pages average 3-5%. If you're below benchmark, test one element at a time: headlines, CTAs, form length, page speed, trust signals. A 1% conversion rate improvement can mean millions in additional revenue for high-traffic sites.

Calculate Conversion Rate Now →
💵

Marketing Budget Calculator

marketing budget calculator budget allocation tool marketing spend planning

The Problem: Budget planning season arrives and you're guessing how much to allocate to each channel. Too much on underperformers wastes money. Too little on winners leaves growth on the table. Without a data-driven approach, budget allocation becomes a political exercise rather than strategic planning.

The Solution: Our marketing budget calculator helps you plan and allocate spending across channels based on historical performance, industry benchmarks, and business goals. Model different scenarios to find the optimal budget distribution that maximizes ROI.

How It Works

The calculator uses performance data (CAC, ROAS, conversion rates) from each channel to recommend optimal budget allocation. Input your total available budget and channel-specific metrics to see how funds should be distributed for maximum impact. Includes industry benchmarks for comparison.

Channel Budget = Total Budget × (Channel Efficiency Score ÷ Sum of All Scores)

Key Benefits

  • Allocate budget based on proven performance
  • Model scenarios before committing spend
  • Defend budget requests with data
  • Optimize portfolio across marketing mix

👤 Who Needs This

  • Marketing directors planning annual budgets
  • CMOs presenting to the C-suite
  • Agency strategists advising clients
  • Small business owners maximizing limited budgets

💡 Pro Tip: Never put 100% of budget in one channel, regardless of past performance. Allocate 70% to proven performers, 20% to emerging opportunities, and 10% to experimentation. This 70-20-10 rule balances growth with innovation and risk management.

Customer Metrics Calculators

5 Calculators

Understand customer economics with tools for acquisition cost, lifetime value, churn, and retention. Critical metrics for sustainable growth and long-term profitability.

💼

CAC Calculator

Essential
CAC calculator customer acquisition cost formula CAC LTV ratio calculator

The Problem: Your marketing drives customers, but you have no idea what each one truly costs to acquire. Sales and marketing spend across multiple channels makes calculating the real customer acquisition cost a nightmare—yet investors, boards, and your own planning require this number.

The Solution: Our CAC calculator consolidates all acquisition costs—advertising, sales team, tools, agencies, content creation—to reveal your true cost per new customer. This essential SaaS and e-commerce metric determines whether your growth is sustainable or a money-losing race to the bottom.

How It Works

Customer Acquisition Cost (CAC) sums all sales and marketing expenses over a period, then divides by new customers acquired. A complete CAC includes ad spend, salaries (marketing + sales), tools/software, agency fees, content production, and overhead allocation. This holistic view prevents underestimating true acquisition costs.

CAC = (Total Marketing + Sales Costs) ÷ Number of New Customers

Key Benefits

  • Understand true customer acquisition economics
  • Calculate maximum affordable ad spend
  • Compare acquisition efficiency across channels
  • Make informed scaling decisions

👤 Who Needs This

  • SaaS founders tracking unit economics
  • E-commerce marketers measuring acquisition efficiency
  • Investors evaluating business sustainability
  • CFOs analyzing marketing profitability

💡 Pro Tip: Healthy businesses maintain a CAC:LTV ratio of 1:3 or better—meaning customer lifetime value is at least 3× acquisition cost. If your ratio is below 1:3, either reduce CAC through optimization or increase LTV through retention, upselling, and reducing churn.

Calculate Your CAC Now →
💎

CLV Calculator

Essential
CLV calculator customer lifetime value formula predict customer lifetime value

The Problem: You focus on acquiring customers but don't know their long-term value. Without understanding customer lifetime value, you can't determine how much to spend on acquisition, which segments deserve premium treatment, or whether your business model is fundamentally profitable.

The Solution: Our CLV calculator projects the total revenue a customer generates over their entire relationship with your business. This metric transforms how you think about acquisition spending, retention investments, and customer segmentation strategy.

How It Works

Customer Lifetime Value (CLV or LTV) estimates the total revenue from a customer across their relationship. Basic CLV multiplies average purchase value by purchase frequency and customer lifespan. Advanced models account for churn rates, margin, and discount rates for present value.

CLV = Average Purchase Value × Purchase Frequency × Customer Lifespan

Key Benefits

  • Justify higher customer acquisition investments
  • Identify your most valuable customer segments
  • Prioritize retention over pure acquisition
  • Set rational CAC targets based on LTV

👤 Who Needs This

  • Subscription businesses modeling unit economics
  • E-commerce brands understanding customer cohorts
  • Product managers prioritizing features for retention
  • Investors valuing customer-based businesses

💡 Pro Tip: Segment CLV by acquisition channel, customer type, and first purchase category. You'll likely discover that some segments have 5-10× higher CLV than others. Focus acquisition on high-CLV segments and develop retention programs specifically for them.

Calculate Your CLV Now →
📉

Churn Rate Calculator

churn rate calculator customer churn formula monthly vs annual churn rate

The Problem: Customers are leaving and you're not sure how fast—or why. High churn silently destroys business value, forcing expensive acquisition just to maintain revenue. Without measuring churn rate accurately, you can't identify the problem or track whether retention efforts are working.

The Solution: Our churn rate calculator measures the percentage of customers who stop doing business with you over a given period. Track monthly, quarterly, or annual churn to identify trends, benchmark against industry standards, and quantify the impact of retention initiatives.

How It Works

Churn rate is the percentage of customers lost during a period divided by customers at the start. A 5% monthly churn means you lose 5% of customers each month—which compounds to losing nearly half your customers annually. The calculator shows both periodic and annualized churn rates.

Churn Rate = (Customers Lost ÷ Starting Customers) × 100%

Key Benefits

  • Quantify customer retention performance
  • Identify churn trends over time
  • Calculate revenue impact of churn reduction
  • Benchmark against industry standards

👤 Who Needs This

  • Subscription businesses tracking retention
  • Customer success teams measuring impact
  • SaaS founders monitoring monthly churn
  • E-commerce brands analyzing repeat purchase rates

💡 Pro Tip: Reducing churn by just 5% can increase profits by 25-95% (Bain & Company research). Even small improvements matter enormously. Best-in-class SaaS companies achieve <2% monthly churn. If you're above 5%, churn reduction should be your #1 priority over acquisition.

Calculate Churn Rate Now →

NPS Calculator

NPS calculator Net Promoter Score formula NPS benchmark by industry

The Problem: You collect customer feedback but struggle to turn surveys into actionable metrics. Satisfaction scores feel vague and aren't comparable across industries. You need a standardized way to measure customer loyalty that predicts growth and identifies detractors before they leave.

The Solution: Our Net Promoter Score calculator transforms survey responses into a single, actionable loyalty metric. Segment customers into Promoters, Passives, and Detractors, then calculate your NPS to benchmark against industry leaders and track improvement over time.

How It Works

NPS uses a single question: 'How likely are you to recommend us to a friend or colleague?' (0-10 scale). Scores 9-10 are Promoters, 7-8 are Passives, and 0-6 are Detractors. NPS = % Promoters minus % Detractors, ranging from -100 to +100.

NPS = % Promoters - % Detractors (score from -100 to +100)

Key Benefits

  • Measure customer loyalty with a proven methodology
  • Benchmark against industry leaders
  • Identify at-risk customers (Detractors)
  • Predict growth through Promoter advocacy

👤 Who Needs This

  • Customer experience leaders
  • Product managers tracking user satisfaction
  • CEOs monitoring company health
  • Support teams prioritizing detractor recovery

💡 Pro Tip: An NPS above 0 means you have more Promoters than Detractors—a good sign. Above 50 is excellent. Above 70 is world-class (Apple, Amazon territory). Focus on understanding WHY Detractors scored low and create closed-loop processes to address their concerns.

🔒

Customer Retention Calculator

customer retention calculator retention rate formula improve customer retention rate

The Problem: You invest in acquisition but overlook the customers you already have. Retention directly impacts profitability—acquiring a new customer costs 5-7× more than keeping an existing one—yet many businesses don't accurately measure or benchmark their retention rate.

The Solution: Our customer retention calculator measures the percentage of customers you keep over a specific period. Compare retention against industry benchmarks, track improvement from retention initiatives, and quantify the revenue impact of keeping customers longer.

How It Works

Customer retention rate measures how many customers remain after a period, excluding new acquisitions. The formula divides customers at the end (minus new customers) by customers at the start. High retention compounds growth; low retention forces expensive acquisition treadmills.

Retention Rate = ((Customers at End - New Customers) ÷ Customers at Start) × 100%

Key Benefits

  • Measure the health of your customer base
  • Track impact of retention programs
  • Calculate revenue protected by reducing churn
  • Focus resources on high-retention segments

👤 Who Needs This

  • Customer success managers tracking outcomes
  • Subscription businesses measuring stickiness
  • Loyalty program managers proving ROI
  • E-commerce brands analyzing repeat purchase rates

💡 Pro Tip: Cohort analysis reveals more than aggregate retention rates. Track retention by acquisition month, channel, or customer segment to identify which cohorts are most likely to stay—then replicate what makes those customers different.

Email ROI Calculator

Popular
email marketing ROI calculator calculate email ROI prove email value

The Problem: Your email list has thousands of subscribers, but you struggle to prove email marketing's value to stakeholders. Between platform costs, content creation time, and list management, calculating true email ROI requires accounting for costs most marketers overlook.

The Solution: Our email ROI calculator measures the return on your complete email marketing investment. Account for platform fees, content costs, team time, and compare against revenue attributed to email campaigns to demonstrate the channel's true profitability.

Key Benefits

  • Prove email marketing's business impact
  • Justify email platform investments
  • Compare email against other channels
  • Identify high-performing campaign types

👤 Who Needs This

  • Email marketing managers defending budgets
  • E-commerce marketers measuring channel value
  • Marketing directors allocating resources
  • Agencies reporting client email performance

💡 Pro Tip: Email marketing averages $36-42 return for every $1 spent—the highest ROI of any marketing channel. If your email ROI is below 30:1, focus on list hygiene, segmentation, personalization, and deliverability optimization. Poor list quality is the most common ROI killer.

Calculate Email ROI Now →

Email Metrics Calculator

email metrics calculator email open rate calculator email performance benchmarks

The Problem: Your email platform shows dozens of metrics, but you're not sure which matter most. Open rates, click rates, bounce rates, unsubscribes—understanding how they connect and benchmark against standards feels overwhelming without a comprehensive analysis tool.

The Solution: Our email metrics calculator analyzes all key performance indicators in one place: open rate, click-through rate, click-to-open rate, bounce rate, unsubscribe rate, and deliverability. Compare against benchmarks and identify exactly where your email program needs improvement.

Key Benefits

  • Analyze all email metrics in one dashboard
  • Benchmark against industry standards
  • Identify deliverability issues early
  • Track list health and engagement trends

👤 Who Needs This

  • Email marketers optimizing campaigns
  • Deliverability specialists monitoring inbox placement
  • Marketing analysts reporting on email performance
  • Newsletter publishers tracking subscriber engagement

💡 Pro Tip: Don't obsess over open rates alone (especially post-iOS 15 privacy changes which inflate them). Click-to-open rate (CTOR) better measures content engagement. Industry average CTOR is 10-15%. Below 8%? Your content isn't resonating—test different formats, offers, and personalization.

Social Media Engagement Calculator

Popular
social media engagement calculator Instagram engagement rate calculate engagement rate

The Problem: You're posting consistently on social media but follower growth feels slow and engagement inconsistent. Without a clear engagement rate metric, you can't benchmark against competitors, identify your best-performing content types, or prove social media's value to stakeholders.

The Solution: Our social media engagement calculator measures the percentage of your audience actively interacting with your content. Calculate engagement rates across platforms, compare against industry benchmarks, and identify which content formats drive the most audience interaction.

Key Benefits

  • Measure true audience engagement quality
  • Compare performance across platforms
  • Identify highest-performing content types
  • Benchmark against industry standards

👤 Who Needs This

  • Social media managers optimizing content strategy
  • Brand managers measuring community health
  • Influencers proving audience quality to sponsors
  • Agencies reporting client social performance

💡 Pro Tip: Instagram engagement rates average 1-3%, Twitter 0.5-1%, LinkedIn 2-4%, TikTok 3-9%. Engagement typically decreases as follower count increases, so compare against similar-sized accounts. Micro-influencers (10-50K followers) often outperform celebrities on engagement rate.

Social ROI Calculator

social media ROI calculator calculate social media return prove social media value

The Problem: Leadership asks 'What's the ROI of social media?' and you struggle to answer. Between organic and paid, brand awareness and direct response, attributing revenue to social feels impossible. Without clear ROI, social media budgets become the first cut when times get tight.

The Solution: Our social media ROI calculator measures the return on your total social investment—including content creation, community management, tools, and advertising. Track revenue attributed to social and prove the channel's contribution to business outcomes.

Key Benefits

  • Prove social media's business impact
  • Justify continued investment in social
  • Compare organic vs. paid efficiency
  • Track ROI improvement over time

👤 Who Needs This

  • Social media directors defending budgets
  • CMOs reporting channel performance
  • Agencies proving value to clients
  • Business owners evaluating social investment

💡 Pro Tip: Not all social value is direct revenue. Calculate 'brand value' metrics: share of voice, brand mentions, sentiment scores, community growth. While harder to monetize directly, these leading indicators predict future sales and should be part of your social ROI story.

Influencer ROI Calculator

influencer ROI calculator influencer marketing return calculate influencer value

The Problem: You're paying influencers thousands of dollars but can't quantify the return. Between CPM-based pricing, engagement metrics, and actual conversions, evaluating whether an influencer partnership delivered value—or comparing different influencers—feels like guesswork.

The Solution: Our influencer ROI calculator measures the return on influencer marketing investments. Account for partnership fees, product costs, and campaign management, then compare against revenue and brand value generated to evaluate every influencer collaboration objectively.

Key Benefits

  • Evaluate individual influencer partnerships
  • Compare performance across influencer tiers
  • Negotiate rates based on historical performance
  • Justify influencer marketing budgets

👤 Who Needs This

  • Influencer marketing managers
  • Brand partnership coordinators
  • DTC brands investing in creator partnerships
  • Agencies managing influencer campaigns

💡 Pro Tip: Calculate cost per engagement (CPE) and cost per acquisition (CPA) for each influencer, not just reach. A micro-influencer charging $500 with 5% engagement and strong conversion rates often delivers better ROI than a celebrity at $50,000 with 0.5% engagement and low intent audience.

A/B Test Significance Calculator

Advanced
A/B test significance calculator statistical significance testing is my A/B test significant

The Problem: You ran an A/B test and variant B shows a 15% improvement—but is it real or just random chance? Without statistical significance testing, you might roll out changes that don't actually work, or worse, hurt performance. Making decisions on insufficient data wastes time and money.

The Solution: Our A/B test significance calculator determines whether your test results are statistically significant. Input visitor counts and conversions for each variant to know if observed differences are meaningful or likely due to random variation.

How It Works

Statistical significance measures the probability that test results aren't due to chance. The calculator uses chi-square or Z-test methodology to compare conversion rates between variants. A 95% confidence level (p < 0.05) is the standard threshold for declaring a winner.

Z-Score = (P₁ - P₂) ÷ √(P×(1-P)×(1/N₁ + 1/N₂))

Key Benefits

  • Validate A/B test results before implementation
  • Avoid false positives from random variation
  • Make confident optimization decisions
  • Stop tests at the right time

👤 Who Needs This

  • CRO specialists running website experiments
  • Product managers testing feature variants
  • Email marketers testing subject lines
  • Growth teams validating hypotheses

💡 Pro Tip: Don't peek at results too early—this inflates false positive rates. Pre-determine your sample size (use our Sample Size Calculator), run the test to completion, then check significance. Sequential testing methods allow early stopping but require adjusted significance thresholds.

Attribution Calculator

Advanced
marketing attribution calculator multi-touch attribution model marketing channel attribution

The Problem: Customers interact with multiple touchpoints before converting—ads, emails, organic search, social media. But which channels actually drive conversions? Last-click attribution oversimplifies the journey, while multi-touch models feel impossibly complex to implement.

The Solution: Our attribution calculator models how credit should be distributed across marketing touchpoints. Compare last-click, first-click, linear, time-decay, and position-based models to understand each channel's true contribution to conversions.

How It Works

Attribution modeling assigns conversion credit to touchpoints in the customer journey. Last-click gives 100% to final touchpoint. First-click credits the discovery channel. Linear distributes equally. Time-decay weights recent touches more. Position-based gives 40% to first and last, 20% to middle.

Linear: Credit = Total Value ÷ Number of Touchpoints (per touch)

Key Benefits

  • Understand true channel contribution
  • Make informed budget allocation decisions
  • Value awareness and consideration channels
  • Move beyond last-click bias

👤 Who Needs This

  • Marketing analysts building attribution models
  • CMOs allocating multi-channel budgets
  • Performance marketers understanding assists
  • Data teams implementing marketing measurement

💡 Pro Tip: No single attribution model is 'correct'—each reveals different insights. Run multiple models in parallel: last-click shows closers, first-click shows acquirers, linear shows the full picture. The truth lies in triangulating across models and using incrementality testing to validate.

Sample Size Calculator

Advanced
A/B test sample size calculator experiment sample size how many visitors for A/B test

The Problem: You want to run an A/B test but don't know how long it needs to run. End too early and your results aren't reliable. Run too long and you waste time that could be spent on the next experiment. Calculating required sample size involves statistics most marketers don't remember from school.

The Solution: Our sample size calculator determines exactly how many visitors or conversions you need for statistically valid A/B test results. Input your baseline conversion rate, minimum detectable effect, and desired confidence level to plan experiments properly.

How It Works

Sample size depends on your baseline conversion rate, minimum detectable effect (MDE), statistical power (usually 80%), and significance level (usually 95%). The calculator uses these inputs to determine visitors needed per variant. Higher baseline rates and larger expected effects require smaller samples.

N = 2 × ((Zα + Zβ)² × P × (1-P)) ÷ MDE²

Key Benefits

  • Plan A/B test duration accurately
  • Avoid underpowered experiments
  • Allocate testing resources efficiently
  • Set realistic experiment timelines

👤 Who Needs This

  • CRO specialists planning experiments
  • Product managers scoping feature tests
  • Researchers designing user studies
  • Data scientists advising on test design

💡 Pro Tip: If required sample size is too large for reasonable test duration, you have options: accept lower statistical power, focus on larger MDE (bigger changes), or test on higher-traffic pages. Sometimes the math tells you an experiment isn't worth running.

Marketing Mix Model Calculator

Advanced
marketing mix model calculator MMM tool optimize marketing budget allocation

The Problem: You invest across multiple channels—paid search, social, display, TV, email—but don't know the optimal budget split. Marketing Mix Modeling (MMM) sounds powerful but requires data science expertise and expensive tools most teams can't access.

The Solution: Our Marketing Mix Model calculator provides a simplified approach to optimizing budget allocation across channels. Input historical spend and results by channel to identify optimal distribution that maximizes overall marketing efficiency and ROI.

How It Works

Marketing Mix Modeling analyzes historical data to understand how each channel contributes to business outcomes. This calculator uses simplified regression-based logic to estimate channel elasticity (how much additional investment yields additional return) and recommend optimal budget allocation.

Optimal Allocation = Based on marginal ROI curves per channel

Key Benefits

  • Optimize budget across entire marketing mix
  • Identify diminishing returns thresholds
  • Model scenarios before committing spend
  • Account for channel interactions

👤 Who Needs This

  • CMOs optimizing marketing investment
  • Marketing strategists planning channel mix
  • Analysts building measurement frameworks
  • Agencies advising on media allocation

💡 Pro Tip: True Marketing Mix Modeling requires 2+ years of consistent data across channels. This calculator provides directional guidance, but for major budget decisions, consider consulting with MMM specialists or using dedicated platforms like Meta's Robyn, Google's LightweightMMM, or commercial solutions.
