ROAS Calculator
Calculate your return on ad spend in seconds.
Return on Ad Spend (ROAS) is the single most important metric for judging whether a paid advertising campaign is making or losing money. It tells you how much revenue you earn for every dollar you put into ads.
Use the calculator below to find your ROAS as both a ratio (e.g. 4x) and a percentage, see your net profit after ad costs, and work out the break-even ROAS you need to hit once your product margin is taken into account.

Frequently asked questions
What is a good ROAS?
A common benchmark is 4:1 ($4 in revenue for every $1 spent), but the right target depends on your profit margin. Low-margin businesses need a higher ROAS to be profitable, while high-margin businesses can stay profitable at a lower ROAS.
What is the difference between ROAS and ROI?
ROAS measures revenue against ad spend only. ROI (return on investment) measures profit against total costs, including product, fulfilment and overheads. ROAS is a campaign efficiency metric; ROI is a profitability metric.
How do I calculate break-even ROAS?
Break-even ROAS = 1 ÷ gross margin. If your gross margin is 40% (0.40), your break-even ROAS is 2.5x — below that you lose money on each sale.
