Affiliate EPC & Monthly Revenue Formula

Compare affiliate programs using Earnings Per Click (EPC) as the universal benchmark across different commission structures.

EPC = Commission Rate (%) × AOV × Conversion Rate (%) / 100
Monthly Revenue = EPC × Monthly Clicks
Annual Revenue = Monthly Revenue × 12
Cookie Weighted EPC = EPC × Cookie Score (longer window = higher score)
Effective Commission = Monthly Revenue / (Monthly Clicks × AOV) × 100

EPC (Earnings Per Click) normalizes different commission rates and AOVs into a single comparable metric. A higher EPC means you earn more for each visitor you send to that affiliate program, regardless of the commission percentage.

How to Use the Affiliate Program Comparison Calculator

1

Enter Program A details

Input the name, commission rate (%), average order value (AOV), and estimated conversion rate for your first affiliate program.

2

Add Programs B and C

Optionally add up to two more programs to compare side by side. Use real data from your affiliate dashboard or program terms.

3

Enter your monthly traffic

Input the number of monthly clicks you send to each program. If you promote all programs equally, use the same click volume.

4

Set cookie window and recurring status

Enter the cookie duration in days (24 hours = 1 day, Amazon Associates = 1 day, most affiliate programs = 30–90 days). Toggle if the program pays recurring commissions.

5

Compare EPC and revenue

The calculator ranks programs by Earnings Per Click and shows your projected monthly and annual revenue for each.

Real-World Scenario Example
