Your numbers
ROAS
Attribution is your assumption and does not establish incremental sales. Excludes costs outside entered margin.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use ROAS = R/A and break-even ROAS = 1/m. R is attributed revenue, A is advertising spend, and m is the pre-ad contribution-margin fraction. Modeled contribution after advertising is Rm−A.
Compare attributed revenue with advertising spend and margin.

Scope and limitations
Attribution is your assumption and does not establish incremental sales. Excludes costs outside entered margin.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
