ROAS Calculator (Return on Ad Spend)

This calculator finds your Return on Ad Spend (ROAS), e.g. 5,000 USD revenue from 1,000 USD ad spend = a 5:1 ROAS.

ROAS measures how much revenue you generate for every dollar spent on advertising — enter your campaign revenue and ad spend to see the ratio instantly.

A ROAS of 4:1 or higher is commonly cited as a solid target for e-commerce campaigns, though the genuinely "right" target varies heavily by profit margin — a business with thin margins may need a much higher ROAS just to break even, while a high-margin product can be profitable at a considerably lower ratio. It's worth remembering ROAS measures revenue, not profit: a campaign can post an impressive-looking ROAS and still lose money once the cost of goods, shipping, and other overhead are factored in, which is why ROAS is best read alongside margin data rather than as a standalone profitability signal.

  • Formula: ROAS = Revenue ÷ Ad Spend.
  • Example: 5,000 USD revenue ÷ 1,000 USD ad spend = 5 (often written as "5:1" or "500%").
  • Benchmark: a ROAS of 4:1 or higher is commonly considered a solid target for most e-commerce campaigns, though the right target varies heavily by industry and margin.

What does a ROAS of 1 mean?

You're making back exactly what you spent on ads (breaking even before accounting for other costs like product, shipping, or overhead).

Is ROAS the same as profit?

No — ROAS only compares revenue to ad spend, not overall profit. A high ROAS on low-margin products can still be unprofitable once product and operating costs are factored in.
