Affiliate Return on Investment Calculator

1. Enter attributed revenue
Use revenue credited to affiliates for the selected reporting period.

2. Add commission expense
Enter commissions approved or expected for the same conversions.

3. Include other program costs
Add network fees, platform charges, creative, incentives, and management costs.

4. Review ROI and profit
ROI compares profit with total cost, while profit margin compares profit with revenue.

5. Test alternatives
Adjust commission or other cost assumptions to evaluate program structure changes.

Total cost = Commissions + Other costs Profit = Affiliate revenue − Total cost ROI = Profit ÷ Total cost × 100 Profit margin = Profit ÷ Affiliate revenue × 100

All revenue and costs must cover the same period and attribution rules. If total cost is zero, ROI is displayed as 0% because division by zero is not meaningful.

What the result means

The main result shows net profit as a percentage of total affiliate program cost. A positive value means attributed revenue exceeds the included costs.

ROI can overstate economic value if returns, cancellations, product costs, or attribution overlap are omitted.

Given: $80,000 in affiliate revenue, $12,000 in commissions, and $4,000 in other costs.

Calculation: Total cost = $16,000. Profit = $80,000 − $16,000 = $64,000. ROI = $64,000 ÷ $16,000 × 100 = 400%.

Result: Affiliate ROI is 400%, with a profit margin of 80%.

For each dollar of included program cost, the program produces four dollars of net profit before unentered product or fulfillment costs.
