How this calculation works
Sales revenue divided by contribution available for advertising.
Worked starting inputs
Example inputs: Selling Price = 100.0, Variable Cost = 60.0. Expected result: Contribution before advertising: $40.00, Break-even ROAS: 2.5×. These are illustrative numbers, not market rates. Change a value to compare scenarios; download the result if useful.
Assumptions and limitations
Manual estimates depend on your data and assumptions.
Every result depends on the entered values. The tool does not fetch marketplace fees, infer current exchange rates or verify supplier policies. It is informational, not tax or financial advice.
