ROAS Calculator Manual

Basic calculation

Enter ad spend and attributed revenue, then select Calculate. The result shows ROAS as a ratio and percentage.

Campaign metrics

Add conversions or orders to calculate CPA and average attributed revenue per conversion. Add a target ROAS to calculate required revenue and maximum ad spend.

Break-even analysis

Add contribution margin to calculate contribution profit before ads, profit after ads, and break-even ROAS. If conversions are available, the calculator also shows break-even CPA.

Target profit margin

Target post-ad profit margin must be lower than contribution margin. The calculator solves the ROAS needed to preserve that margin after advertising cost.

Exports

Copy, CSV, JSON, and Print / Save PDF are available only for a current calculated result. Editing inputs makes the prior result stale until you calculate again.
