Break-even CPA is not a market benchmark

Break-even CPA is calculated from your own pricing and costs. It does not tell you what CPA Meta or Google ads will actually achieve.

Know what is not included

This simplified calculation excludes fixed overhead, taxes, returns/refunds, repeat purchases, and attribution differences. Enter fees and shipping as variable costs where relevant.
