Break-even ROAS
2.50x
- Required ad spend
- $33,333
Spend $33,333 to hit $100,000 at 3.00x — clears break-even (2.50x). Scale.
Required Spend = Revenue Goal ÷ Target ROAS · Break-Even ROAS = 100 ÷ Gross Margin %
The canon
Budget backward from the revenue target — then prove it clears break-even before you spend.
The benchmark
Target ROAS must exceed break-even ROAS (100 ÷ margin%) — growth below break-even burns cash.
