How it works

ROAS is revenue divided by ad spend. A ROAS of 4.00x, also written 400%, means each $1 of ads brought back $4 of revenue. The ratio and the percent are the same number.

ROAS = revenue ÷ spend

ROAS % = revenue × 100 ÷ spend

revenue = ROAS × spend

spend = revenue ÷ ROAS

Worked example

Your ads bring in $2,000.00 of revenue on $500.00 of ad spend.

  1. 1ROAS$2,000.00 ÷ $500.00 = 4.00x
  2. 2ROAS as a percent$2,000.00 × 100 ÷ $500.00 = 400.00%

What is a good ROAS?

Benchmarks vary by industry and platform, so this page gives no number. Above 1.00x the ads brought in more revenue than they cost, but whether that pays depends on your margin.

Questions

Is ROAS the same as ROI?

No. ROAS compares revenue with ad spend. ROI compares profit with total cost, so a campaign can have a high ROAS and still lose money once product cost and other expenses count.

What ROAS do I need to break even?

It depends on your margin. If your margin before ad costs is 40%, you need 100 ÷ 40 = 2.50x to cover the ad spend. Use the margin calculator to find your margin.

Which revenue should I enter?

Enter the revenue your ad platform or store credits to the ads. Platforms attribute sales in different ways, so compare numbers from the same source.

What happens when ad spend is 0?

ROAS divides by spend, so it is not defined at $0. The result stays blank and the page asks for a value above 0.
