Find your return on ad spend in seconds — plus the break-even ROAS your margin actually requires, and your profit after ad spend. Free, no signup.
A 4:1 ROAS is a common “good” benchmark, but the number that matters is your break-even ROAS — 1 ÷ your profit margin. Anything above it is profit.

ROAS (return on ad spend) measures how much revenue you earn for every dollar spent on ads. You calculate it as revenue from ads ÷ ad spend. A 4:1 ROAS ($4 per $1) is a common benchmark, but the real target is your break-even ROAS: 1 ÷ your profit margin.
“Good” depends on your margin — but here’s what the data says the typical ecommerce advertiser actually returns.
is the approximate average ROAS across industries — the median is just 2.04:1
Run your numbers above, then book a call — we’ll find where your ad spend is leaking return and how to push it past break-even.
Add up the revenue directly attributable to the campaign you’re measuring.
Use what you actually paid the ad platform for that same campaign and period.
Revenue ÷ ad spend is your ROAS. Then divide 1 by your profit margin to get break-even ROAS. Beat it and you profit; fall short and you lose money.
A 4:1 ROAS sounds great — until you learn your margin is 20%. Then break-even is 5:1 and that “great” campaign is quietly losing money. ROAS only means something next to your break-even number, which your profit margin sets. That’s why this calculator asks for margin: it tells you not just what you earned per ad dollar, but whether that number is actually profit. Scale what clears break-even; fix or cut what doesn’t.
A 4:1 ROAS — $4 in revenue for every $1 of ad spend — is a widely cited benchmark for a healthy return, though the average across industries is closer to 2.9:1. The truly correct target is your break-even ROAS, which equals 1 ÷ your profit margin. Anything above break-even is profit.
ROAS = revenue from ads ÷ ad spend. For example, $40,000 in revenue from $10,000 of ad spend is a 4:1 ROAS, or 4×. It measures gross efficiency; to know if it’s profitable, compare it to your break-even ROAS (1 ÷ your profit margin).
Break-even ROAS is the return you need just to cover costs, and it equals 1 ÷ your profit margin. A 25% margin needs a 4:1 ROAS to break even; a 50% margin only needs 2:1. Any ROAS above your break-even number is profit; anything below it means the campaign loses money.
ROAS measures gross revenue against ad spend only, while ROI (return on investment) measures profit against your total marketing cost. ROAS is a quick ad-efficiency signal; ROI shows true profitability across all costs. A campaign can show a strong ROAS but a weak ROI once every cost is counted.
