ROAS measures revenue generated relative to advertising cost. POAS, or profit on ad spend, shifts attention from revenue to profit. That distinction matters when products have very different margins.
ROAS answers a revenue question
A 4x ROAS means $4 of attributed revenue for every $1 spent on ads. It does not tell you how much of that revenue remains after product and order costs. Calculate the standard ratio with the ROAS Calculator.
POAS answers a profit question
POAS compares a defined profit measure with advertising spend. Teams must be clear about whether “profit” means gross profit, contribution profit or another internal definition.
Product mix can reverse the ranking
Campaign A may have lower ROAS but sell high-margin products, while Campaign B has higher ROAS but sells low-margin products. Profit-based reporting can show that Campaign A contributes more economic value.
Start with clean margin inputs
Profit metrics are only as accurate as the cost data behind them. Use the Profit Margin Calculator for basic margin analysis, then incorporate variable order costs where relevant.
Use break-even ROAS as an accessible bridge
If full POAS reporting is not available, break-even ROAS connects revenue-based platform reporting to contribution economics. The Break-Even ROAS Calculator can establish that floor.
Turn the guide into your own numbers
Use your real costs and campaign data instead of relying on a generic benchmark.

What does POAS mean?
POAS commonly means Profit on Ad Spend.
Is POAS better than ROAS?
It can be more economically informative, but it requires reliable cost and profit data. ROAS remains useful for platform optimization.
Can two products have the same ROAS but different POAS?
Yes. Different margins and variable costs can produce very different profit outcomes at the same revenue ROAS.
