What is ROAS?
Revenue from your ads divided by what the ads cost. A 4x ROAS means every 1 spent brought back 4 in revenue; whether that is profitable depends on your margin.
ROAS Revenue from ads ÷ Ad spend
Break-even ROAS 1 ÷ Margin before advertising
Frequently asked questions
What is a good ROAS?
There is no single number that suits every business; a good ROAS depends on your margin. Start from break-even ROAS (1 ÷ margin): at a 40% margin it is 2.5x, and anything above it means the ads are adding to gross profit. How far above that line to aim depends on your fixed costs and growth plans.
What is the difference between ROAS and ROI?
ROAS divides revenue by ad spend. ROI divides profit by the investment, so it counts product cost, shipping and fees as well. A campaign with a 3x ROAS can still have a negative ROI if margins are thin. To see profit per order, use the Ad Profitability Calculator.
How do I express ROAS as a percentage?
Multiply the ratio by 100: a 4.2x ROAS is the same as 420%. Some ad platforms and reports use the percentage and others the multiple, so the calculator shows both.
What is ACoS and how does it relate to ROAS?
ACoS (advertising cost of sales) is ad spend divided by the revenue from those ads, the inverse of ROAS: ACoS = 1 ÷ ROAS. A 4x ROAS equals a 25% ACoS. The term is mostly used in Amazon advertising.
Should revenue include sales tax or VAT?
What matters is that both sides use the same basis. Ad platforms report whatever value your site sends with the conversion event, and whether that includes tax depends on how your store is set up. Work out your margin on the same basis before comparing against break-even ROAS.
