The ROAS formula

ROAS
Revenue from ads ÷ ad spend. A 4x ROAS means $4 of revenue for every $1 spent.
Profit ROAS
ROAS × gross margin. It converts the revenue ratio into the margin dollars each $1 of spend actually returns.
ROI on ad spend
(Gross profit − ad spend) ÷ ad spend, as a percentage. Profit-based, so a 4x ROAS at a 30% margin is still a 20% loss.
Break-even ROAS
1 ÷ gross margin. At a 60% margin you need roughly 1.67x ROAS before ads stop losing money.
Target spend
Revenue ÷ target ROAS shows the maximum spend that still hits your goal at today's revenue.

Frequently asked questions

What is ROAS?
ROAS (return on ad spend) is the revenue generated by advertising divided by the amount spent on that advertising. A 4x ROAS means every $1 of ad spend produced $4 in revenue.
How do you calculate ROAS?
Divide revenue attributed to your ads by the ad spend for the same period. $40,000 in revenue from $10,000 of spend equals a 4x ROAS, or 400%.
What is the difference between ROAS and ROI?
ROAS compares gross revenue to ad spend. ROI subtracts the spend (and often other costs) first, so it measures profit rather than revenue. A campaign can show a strong ROAS and still lose money at thin margins.
What is a good ROAS?
It depends on margins. Many ecommerce brands target 3x to 4x, while high-margin software businesses can be profitable below that. Compare your ROAS against your break-even ROAS instead of a generic benchmark.
What is break-even ROAS?
Break-even ROAS is 1 divided by your gross margin. At a 60% gross margin your break-even is about 1.67x, so anything above that contributes profit and anything below loses money.
How much can I spend and still hit my target ROAS?
Divide the revenue your ads produce by your target ROAS. If ads generate $40,000 and you want a 5x return, spend must stay at or below $8,000 — otherwise revenue has to rise instead.
