What is ROAS Calculator?
The ROAS Calculator measures Return on Ad Spend: the revenue generated for every unit of currency spent on advertising. It computes ROAS from revenue and ad spend, solves backwards for required revenue or maximum profitable spend, and derives break-even ROAS from your profit margin so scaling decisions rest on real unit economics, not guesswork.

Frequently Asked Questions
What is a good ROAS?
There is no universal number. A 4x ROAS is a common e-commerce benchmark, but what matters is your break-even ROAS: with a 30% margin you need about 3.33x just to avoid losing money. Aim comfortably above your own break-even.
What is the difference between ROAS and ROI?
ROAS equals revenue divided by ad spend expressed as a ratio like 4x, while ROI equals revenue minus cost divided by cost, expressed as a percentage that can be negative. ROAS answers how much you get back per unit spent; ROI answers net profitability.
How is break-even ROAS calculated?
Break-even ROAS equals 1 divided by profit margin. At a 25% margin it is 4x; at 50% it is 2x. Below that ROAS, the campaign loses money on every sale.
Does ROAS include product costs and fees?
No. Plain ROAS only compares revenue to ad spend. That is why this tool also asks for your profit margin: the break-even figure turns raw ROAS into an actual profitability check.
