How ROAS works

ROAS = revenue from ads ÷ ad spend

ROAS is the revenue you earn for every $1 of ad spend. Your target comes from your margin, not a platform average: break-even ROAS = 1 ÷ gross margin. Worked examples and POAS are in our guide to calculating ROAS.

How is ROAS calculated?

Divide revenue from ads by ad spend. $50,000 of revenue from $10,000 of spend is a 5.0x ROAS, or 500%.

How do I calculate break-even ROAS?

Divide 1 by your gross margin. At a 40% margin, break-even ROAS is 1 ÷ 0.40 = 2.5x. Enter your margin above and the calculator shows it.

What does a ROAS of 2.5 mean?

You get $2.50 back for every $1 spent. It is profitable only when your gross margin is above 40%.

What does a ROAS of 1.5 mean?

You get $1.50 for every $1 spent. It covers costs only when your gross margin is about 67% or higher.

What does a 4:1 ROAS mean?

$4 of revenue for every $1 of ad spend, or 400%. It breaks even at a 25% gross margin.

What ROAS is 25% ACoS?

ACoS is ad spend ÷ revenue, the inverse of ROAS. 25% ACoS equals a 4.0x ROAS.

ROAS vs ROI, what is the difference?

ROAS is revenue ÷ ad spend. ROI is (profit − investment) ÷ investment and counts every cost, so it is the stricter measure.
