Calculating break-even Return on Ad Spend

Take your gross margin as a decimal and divide 1 by it. A 50% margin gives a 200% break-even Return on Ad Spend; a 20% margin gives a 500% break-even Return on Ad Spend.

This is the minimum Return on Ad Spend where ads pay for the product. It does not yet account for fixed costs — so your profit target should sit comfortably above it.

From break-even to profit targets

Once you know break-even Return on Ad Spend, set target return on ad spend with a margin of safety for shipping, fees, returns, and overhead. Many brands target 1.3–2× their break-even Return on Ad Spend.

Better still, bid on Profit on Ad Spend so the system optimizes profit directly instead of a revenue proxy you have to constantly re-derive.
