How to use this calculator
Why break-even ROAS is different from ROAS
A normal ROAS calculator tells you what happened after spend and revenue are known. Break-even ROAS tells you the minimum return you need before launching or scaling.
Costs to include
Include product cost, fulfillment, platform fees, payment processing, refund reserve, and any per-order handling cost. Leaving costs out makes the ROAS target look safer than it is.
- Use fixed dollar costs for shipping and handling.
- Use percent costs for platform, payment, and refund assumptions.
- If contribution profit is negative, the calculator stops instead of showing a fake target.
