What Is a Good ROAS for Ecommerce?

Understand what a good ROAS is for ecommerce, why it depends on margin, and how to compare campaign ROAS with break-even ROAS. This guide explains the practical seller math behind good ecommerce ROAS, with a focus on net profit rather than surface-level revenue.

There is no universal good ROAS

Paid acquisition should be compared against break-even ROAS, not only platform-reported ROAS. If reported ROAS is below the break-even point, more sales can still mean lower profit.

Margin decides whether ROAS is good

Paid acquisition should be compared against break-even ROAS, not only platform-reported ROAS. If reported ROAS is below the break-even point, more sales can still mean lower profit.

Paid ads example

For example, a product selling for 50 dollars may have 18 dollars in product cost, 5 dollars in shipping, 4 dollars in platform and payment fees, and 2 dollars of expected return loss. That leaves 21 dollars before ads, so the campaign needs enough ROAS to keep acquisition cost below that amount.

Why high ROAS can still lose money

Paid acquisition should be compared against break-even ROAS, not only platform-reported ROAS. If reported ROAS is below the break-even point, more sales can still mean lower profit.

How to use break-even ROAS

Paid acquisition should be compared against break-even ROAS, not only platform-reported ROAS. If reported ROAS is below the break-even point, more sales can still mean lower profit.

Practical ROAS benchmarks

Paid acquisition should be compared against break-even ROAS, not only platform-reported ROAS. If reported ROAS is below the break-even point, more sales can still mean lower profit.

Use the calculator

Check whether your target is realistic with the break-even ROAS calculator. For platform-specific campaigns, test the numbers in the Shopify profit calculator, TikTok Shop profit calculator, or Amazon FBA profit calculator.

Important note

These examples are simplified planning models. Always compare calculator outputs with your actual marketplace reports, payment statements, advertising dashboards, and accounting records.
