About This Calculator

ROAS (Return on Ad Spend) measures revenue generated per dollar of advertising spend. A 4x ROAS means you earned $4 for every $1 spent on ads. This calculator also shows net profit from ads — because ROAS doesn't account for the cost of goods, a 4x ROAS on a 30% margin product is actually losing money.

Estimates only — not financial, tax, legal, or investment advice. Verify important results with a qualified professional before making decisions.

ROAS = revenue ÷ ad spend; net profit = revenue − spend; return on ad spend % = (revenue − spend) ÷ spend × 100
