    Marketing ROI Calculator

    Work out ROI, ROAS, cost per conversion and your break-even point from your ad spend, revenue and profit margin.

    Runs in your browser: nothing you type is uploaded.

    Sales your tracking credits to the campaign.

    What's left of each sale after the cost of the product or service, before marketing. Leave blank to count all revenue as profit.

    Agency fees, creative, software, freelancers.

    Results

    Enter your ad spend (or other marketing costs) and revenue to see ROI, ROAS and your break-even point.

    ROI = (revenue × margin − marketing cost) ÷ marketing cost. ROAS = revenue ÷ ad spend. Break-even ROAS = 1 ÷ margin.

    All figures are in US dollars. Nothing you enter leaves your browser.

    How to use it

    1. 1

      Enter the revenue the campaign brought in, and your ad spend.

    2. 2

      Add your profit margin and any other marketing costs, such as agency fees, creative or software.

    3. 3

      Optionally add clicks and conversions to see cost per click, conversion rate and cost per conversion.

    4. 4

      Read the verdict and your break-even ROAS: the return you need just to cover the costs.

    Why it matters

    ROAS alone can mislead. A 3× return sounds good, but if only 30 cents of each sales dollar is profit, you lose money. Break-even ROAS is 1 divided by your margin, so a 30% margin needs more than 3.3× just to break even.

    ROI counts everything you spent on the campaign, not only ads, and measures the profit left after those costs. That makes it the better number for deciding whether to spend more.

    The result is only as good as the revenue figure. Use one attribution method consistently, such as GA4 conversions or your store's own orders, and don't mix numbers from different tools.

    Frequently asked questions

    What's the difference between ROI and ROAS?

    ROAS is revenue divided by ad spend. ROI is profit after all marketing costs divided by those costs, as a percentage. ROAS ignores margin and other costs, and ROI doesn't.

    What is a good ROAS?

    It depends on your margin. A business with an 80% margin can profit at 1.25×, while one with a 25% margin needs 4× just to break even. Use the break-even ROAS shown here as the floor.

    How do I find my profit margin?

    Subtract what the product or service costs you to deliver from its price, then divide by the price. Use the margin before marketing costs, which are counted separately.

    Should I include my agency fee or salary costs?

    Include agency fees, creative and software that belong to the campaign. Salaries are optional: include them if you want the full cost, and keep the choice the same each time you compare campaigns.

    Why does it say my margin was assumed?

    If you leave the margin blank, all revenue is treated as profit. That flatters the results, so add your real margin for an honest ROI.
