ROAS Calculator

Two calculators in one

Measure mode tells you the ROAS you actually got (revenue ÷ ad spend). Target mode tells you the ROAS you need to be profitable, based on your real unit economics.

Why break-even ROAS matters

A ROAS of 4 sounds great until your product margin is only 20% — then you lose money. Break-even ROAS = 1 ÷ product margin. The ladder shows the ROAS required to keep 10%, 20%, 30% or 50% net margin after ads. If a target exceeds your product margin, it is impossible — and the tool flags it.

Frequently asked questions

What's the difference between the two modes?

Measure mode = the ROAS you achieved (revenue/spend). Target mode = the ROAS you need to hit a given profit, based on your costs and margin.

What counts as variable costs?

Per-order costs beyond the product: shipping, packaging, payment/transaction fees. As % of selling price.

Why is a target sometimes 'impossible'?

If the net margin you want is higher than your product margin, no ROAS can deliver it — raise prices or cut costs first.
