ROAS = revenue ÷ spend

Break-even ROAS = 1 ÷ profit margin
Break-even ROAS assumes you need contribution margin to cover ad spend. It doesn’t include fixed costs or CAC payback timing.

What is ROAS?

ROAS (Return on Ad Spend) measures the revenue generated for every dollar spent on advertising. It's the simplest way to evaluate whether your ads are profitable.

ROAS formula

ROAS = Revenue ÷ Ad spend

A ROAS of 4.0 means you generated $4 in revenue for every $1 spent on ads.

How to use this calculator

Calculate ROAS: enter your ad spend and revenue.
Calculate break-even ROAS: enter your profit margin to find the minimum ROAS needed to break even.

Understanding break-even ROAS

Your break-even ROAS depends entirely on your profit margins.

Break-even ROAS = 1 ÷ Profit margin (as decimal)
Profit MarginBreak-Even ROAS
20%5.0x
25%4.0x
33%3.0x
50%2.0x
66%1.5x

Example: If your profit margin is 25%, you need a ROAS of at least 4.0x just to break even. Anything above 4.0x is profit.

ROAS vs ROI

ROAS measures revenue vs ad spend (doesn't account for product costs).
ROI measures profit vs total investment (accounts for all costs).

ROAS is simpler and more commonly used for campaign optimization. ROI gives you the full picture of profitability.

What’s a good ROAS?

It depends on your margins, but general benchmarks:

ROASInterpretation
Below break-evenLosing money
1x-2x below break-evenLosing money (but may build awareness)
At break-evenCovering costs
1.5x break-evenHealthy profit
2x+ break-evenStrong performance

Why break-even ROAS matters more than raw ROAS

A 3x ROAS sounds great—until you realize your margins are only 20% and you need 5x to break even. Always calculate your break-even ROAS first, then evaluate campaigns against that threshold.
