ROAS is one of the most common paid media metrics, but it should be interpreted carefully. A campaign can have strong ROAS and still be unprofitable if margins are low, fulfillment costs are high, or conversion tracking is incomplete. This calculator helps estimate ROAS and margin-adjusted performance.
What this calculator does
Calculate return on ad spend from ad spend and conversion revenue, then estimate profitability based on gross margin.
How to use it
Enter ad spend, conversion revenue, gross margin, and management cost. The calculator returns ROAS, break-even ROAS, gross profit, net profit after marketing cost, and ROI.
Formula and assumptions
- ROAS = conversion revenue ÷ ad spend.
- Gross profit = conversion revenue × gross margin.
- Net profit = gross profit − ad spend − management cost.
- Break-even ROAS = 1 ÷ gross margin.
Assumptions
- Revenue must be accurately tracked or imported into the advertising platform.
- ROAS does not automatically account for margin, management fees, refunds, or operating expenses.
- For lead generation, use estimated lead value or closed-won revenue instead of raw lead count.
How to interpret your result
ROAS is useful, but margin-adjusted profit is usually a better business metric. A 4:1 ROAS may be excellent for a high-margin service business and poor for a low-margin retailer.
