ROAS Calculator
A high ROAS looks great, but profit is what pays the bills. This calculator shows your ROAS, the profit behind it, and the break-even ROAS you must exceed to actually make money.
How it works
ROAS is ad revenue divided by ad spend. Ad profit is (revenue × margin) minus spend. Break-even ROAS is 1 divided by your product margin — the minimum ROAS before an ad loses money.
Worked example
Example: Revenue €5,000, spend €1,000, margin 40% → ROAS 5x, profit €1,000, break-even 2.5x.
Recommendations
- Track break-even ROAS, not just ROAS — many campaigns die below it.
- Use your true contribution margin, including fulfillment and fixed costs.
- Segment ROAS by campaign and product to find what really scales.
Tips & advice
- A 5x ROAS with 25% margin still loses money if your break-even is 4x.
- Double the ad budget only if ROAS holds — don't scale into unprofitable spend.
- Account for returns and refunds in revenue before computing ROAS.

Net Margin Calculator
Gross margin tells you about your product; net margin tells you about your business. After every cost is paid, what percentage of revenue is actually yours?
Sale Price Calculator
Cost-plus pricing is a recipe for margin erosion. This calculator works the other way: you decide the margin, and it tells you the price that guarantees it.
Break-even Calculator
Before you make a euro of profit, you must cover your costs. This calculator finds the exact sales volume and revenue where you break even — and where profit begins.
Cash Flow Calculator
Profit is not cash. This calculator compares your monthly income with your monthly expenses to show what actually remains — your monthly surplus, its annual total and your savings rate.

A ROAS above your break-even ROAS is profitable. For a 40% margin, break-even is 2.5x, so aim above that after accounting for all costs.
Margin is profit divided by the selling price. Markup is profit divided by the cost. A 60% margin equals a 150% markup.
