How to read your break-even ROAS

01 / explainer

ROAS in Ads Manager measures gross revenue per ad dollar — not profit. Three things decide whether a reported ROAS actually makes you money:

[ 01 ]

Fees come off first

Referral (6%), FBT fulfillment, the $0.30 transaction fee, and creator commissions all come out before ad spend. On a $29.99 product those add up to roughly a third of your revenue before you've paid for the product or the ads.

[ 02 ]

Break-even ROAS is your floor

It equals 1 ÷ your profit-before-ads margin. If your margin before ads is 50%, you break even at a 2.0x ROAS — anything below that is paid traffic burning cash even though Ads Manager shows a positive ROAS.

[ 03 ]

Scale only above the floor

Corrected ROAS — revenue minus returns and fee refunds — is what you should scale against. Budget increases are safe only when your reported ROAS clears the break-even line with room for return rates.
