How This Calculator Works
Use this roas tool for quick estimation, comparison, and planning intent while keeping formula assumptions visible.
Use the ROAS calculator to understand how much revenue a campaign generates for each dollar of ad spend.
ROAS divides attributed revenue by ad spend. It does not include product costs, refunds, labor, or overhead.
Formula
ROAS = attributed revenue / ad spend.
Example Calculation
$12,000 revenue from $3,000 ad spend equals 4.0x ROAS.

Assumptions and Limitations
The ROAS Calculator is most accurate when the inputs match current real-world numbers and when you review the formula, assumptions, and related calculators before acting.
- Refunds, chargebacks, taxes, payment fees, labor, seasonality, and contracts can change real outcomes.
- The result is a planning estimate, not accounting, tax, legal, or professional advice.
- Verify assumptions against current records before changing prices, budgets, or strategy.
