What is the ROAS Calculator?

Return on ad spend tells you how much revenue each unit of advertising brings back. Enter any two of revenue, ad spend and ROAS and the calculator solves the third, showing ROAS as a ratio (4.0×), a percentage (400%) and revenue per dollar.

Add your gross margin and other costs to see whether that ROAS actually makes money: gross profit, net profit after ads, ROI and your break-even ROAS.

ROAS formula

ROAS = revenue from ads ÷ ad spend. $12,000 in revenue from $3,000 of ads is a ROAS of 4 (400%). Google Ads target ROAS bidding uses the percentage form, so a 4× goal is entered as 400%.

ROAS versus ROI

ROAS ignores the cost of what you sell. ROI subtracts it. With a 30% margin, a 4× ROAS turns $3,000 of ads into $3,600 gross profit — a $600 net profit and a 20% ROI. With a 20% margin the same ROAS loses money.
