Frequently Asked Questions
How is ROAS calculated?
Divide the revenue attributed to your ads by the amount you spent on them. Spending 1,000 dollars to generate 4,000 in revenue is a 4x ROAS. The calculator returns the figure instantly for any campaign, channel, or time period.
What is a good ROAS in 2026?
Many teams treat 4x as a healthy target, but the real answer depends on your margins. A business with thin margins may need 6x to profit, while high margin products can thrive at 2x. Calculate your break even ROAS first.

Yes. It is free after creating a Brainito account, with no limits on how many campaigns you check, so you can audit your whole ad account whenever you review your spend.
