About Marketing ROI
ROI (Return on Investment) measures profitability: ROI = (Revenue - Investment) / Investment × 100. ROAS (Return on Ad Spend) shows revenue per dollar spent. Track multiple channels to optimize your marketing budget.
What is Marketing ROI Calculator?
The Marketing ROI Calculator is a free online tool that measures the profitability of your marketing campaigns across one or many channels. It uses the standard formula ROI = (Revenue - Investment) / Investment x 100 and also reports ROAS (Return on Ad Spend), net profit, and your breakeven point. Add optional funnel and customer data — impressions, clicks, leads, conversions, new customers, and lifetime value — and it computes a full set of efficiency metrics: CAC, CPL, CPA, CPC, CPM, conversion rate, the LTV:CAC ratio, and the payback period. Pick your currency, enter what you spent and the revenue each channel produced, and the tool instantly compares them so you can see which campaigns pay off and which drain the budget. You can add multiple channels — Google Ads, Facebook, email, and more — to benchmark them side by side, ranked by ROI. Everything runs in your browser, with no signup and no data leaving your device.

Why use this tool?
Marketing budgets are wasted when nobody knows which channel actually drives profit. Calculating ROI turns spend into a clear performance number, so you can defend a budget, justify a campaign, and shift money to what works. ROAS adds a second lens by showing revenue earned per dollar of ad spend, while efficiency metrics like CAC, CPL, CPC, and CPM reveal exactly where money leaks in the funnel. The LTV:CAC ratio and payback period tell you whether each customer is worth more than they cost to acquire — the foundation of sustainable growth. Comparing several channels side by side, ranked by ROI, reveals winners and losers at a glance. Because the calculator runs entirely in your browser, your campaign figures stay private and the results are instant. Whether you report to a client, a manager, or yourself, hard ROI numbers make every marketing decision easier to justify.
Examples
You spend $2,000 on Google Ads and earn $8,000. The tool shows an ROI of 300%, a ROAS of 4.0, and $6,000 net profit.
Add 200,000 impressions, 5,000 clicks, 500 leads, and 120 new customers to that $2,000 spend. The tool returns a $16.67 CAC, $4 CPL, $0.40 CPC, and $10 CPM, with a 2.4% conversion rate.
Add Facebook ($1,000 in, $2,500 out) and email ($300 in, $2,400 out). The tool ranks them, revealing email has the highest ROI and flagging it as the top performer.
Frequently Asked Questions
How is marketing ROI calculated?
ROI equals revenue minus investment, divided by investment, multiplied by 100. A result of 200% means you earned three dollars back for every dollar spent — the original dollar plus two in profit.
What is the difference between ROI and ROAS?
ROI measures profit relative to total cost, while ROAS (Return on Ad Spend) measures gross revenue per dollar of ad spend. ROAS does not subtract costs, so it is usually a higher number than ROI.
What are CAC, CPL, CPA, CPC and CPM?
CAC is your cost to acquire one customer (spend ÷ new customers). CPL is cost per lead, CPA is cost per acquisition or conversion, CPC is cost per click, and CPM is cost per thousand impressions. They pinpoint where your budget is efficient or wasteful.
What is a good LTV:CAC ratio?
A ratio of 3:1 — meaning each customer is worth three times what they cost to acquire — is a widely used healthy benchmark. Below 1:1 you lose money on every customer; well above 3:1 may mean you are under-investing in growth.
What costs should I include in the investment?
Include everything that the campaign consumed: ad spend, creative production, agency or freelancer fees, and any tools. Leaving out costs inflates your ROI and hides the true result.
Is the calculator free and private?
Yes. The Marketing ROI Calculator is completely free with no signup or limits, and all calculations happen inside your browser, so your investment and revenue figures are never uploaded or saved on a server.
