Formula notes

Break-even ROAS = revenue / maximum ad spend before profit reaches zero.

If contribution before ads is negative, paid acquisition cannot break even on the first order.

Formula

Break Even ROAS Calculator follows a simple seller economics model: revenue minus product cost, shipping, platform fees, payment fees, advertising, and other order-level costs.

  • Revenue is based on selling price and buyer-paid charges.
  • Costs include product, shipping, fees, ads, and overhead where relevant.
  • Margin is net profit divided by revenue.
  • Break-even metrics estimate the point where profit reaches zero.

Example workflow

A seller can enter a target price, product cost, shipping cost, and fee rate, then compare profit margin before deciding whether the item deserves more research.

  • Check the default result first.
  • Change product cost or fee rate to match your supplier and marketplace.
  • Try a higher and lower selling price.
  • Use the result to reject weak products faster.

Common mistakes

The most common issue is treating marketplace revenue as profit. Break Even ROAS Calculator helps expose hidden costs before they become expensive inventory mistakes.

  • Forgetting shipping, returns, or ad costs.
  • Using a generic fee rate for every category.
  • Ignoring fixed fees on low-priced products.
  • Making sourcing decisions before checking break-even price.

FAQ

Is a lower break-even ROAS better?

Yes. A lower break-even ROAS means you can spend more on ads relative to revenue and still avoid losing money.

Should I include repeat purchases?

For a conservative first-order calculation, do not include them. For mature stores, compare this result with customer lifetime value.
