Break-even ROAS Calculator
Use price, product cost, shipping, and selling fees to find your break-even ad spend.
How it is calculated
The calculation is universal: contribution before ads is the most you can spend to acquire one order without losing money. The US version uses dollar inputs and your actual combined selling fee rate.
Break-even ROAS = revenue ÷ contribution before ads × 100
Example
At a $50 price, $18 product cost, $6 shipping, and 13% selling fees, contribution before ads is $19.50 and break-even ROAS is 256.4%.
