How to use this roas calculator

Enter values from the same reporting period and use consistent definitions. Then select Calculate. The tool performs the calculation locally in your browser and shows the result immediately.

Formula

ROAS = Revenue from Ads ÷ Advertising Spend

Example

If you spend $1,000 on ads and attribute $3,500 in revenue to those ads, your ROAS is 3.5x (350%).

What this metric tells you

ROAS is a revenue-efficiency metric. It tells you how many dollars of attributed revenue were generated for each dollar spent on advertising. A higher ROAS is not automatically more profitable: product cost, shipping, refunds, payment fees and operating costs still matter.

How to interpret the result

  • Compare ROAS with your break-even ROAS, not with a universal benchmark.
  • Use the same date range and attribution scope for revenue and ad spend.
  • Segment by campaign, product, market or device when a blended account number hides important differences.
Important: Calculators provide estimates based on the inputs you supply. They do not replace platform reporting, accounting records, tax advice or professional financial analysis.

Frequently asked questions

What is a good ROAS?

A good ROAS is one that is comfortably above your break-even ROAS and supports your profit goals. The required level differs by margin, repeat purchase behavior and operating costs.

Is 4x ROAS the same as 400%?

Yes. A 4x ROAS means $4 of attributed revenue for each $1 of ad spend, which is 400%.

Does ROAS equal profit?

No. ROAS compares revenue with ad spend. It does not subtract cost of goods, shipping, transaction fees, refunds or overhead.
