Break-even ROAS Calculator
Enter price, cost, shipping, fees, and refund reserve to find the ROAS needed to break even and the ROAS needed to keep target profit.
Break-even ROAS
1.99
Target-profit ROAS
2.95
Contribution before ads
24.59
How to read it: if actual ROAS is below break-even ROAS, ads are likely losing money. If actual ROAS is above target-profit ROAS, scaling is safer to review.

Read the result: a hypothetical example

In one currency: selling price 49, product cost 14, seller-paid shipping cost 6, payment fee 4%, and refund reserve 5%. These are illustrative inputs, not industry benchmarks or your store data.

Contribution before ads
49 − 14 − 6 − 1.96 − 2.45 = 24.59
Break-even ROAS
49 / 24.59 ≈ 1.99×
ROAS to retain 8 per order
49 / 16.59 ≈ 2.95×

Match definitions before comparing ad reports

Use post-discount product revenue on a consistent basis. The refund reserve here is a simple percentage of price, not a complete returns-cost model. Do not reserve the same refund again against revenue already net of that refund. This quick model excludes fixed overhead, taxes, payout timing, and inventory cash needs. ROAS values using different currencies or revenue definitions are not directly comparable.

When contribution before ads is zero or negative, no finite break-even ROAS exists. When the target retained amount meets or exceeds contribution, no positive target ad budget remains. N/A represents a model boundary, not a reason to spend more.

API Access

Break-even ROAS Calculator is available by API

Paid members can create an API key from settings and grant each key only the scopes it needs. The full secret is shown once; store it in an environment variable or secret manager, never in code, URLs, logs, or chat. Current plan and API responses determine quota and rate limits.
