Affiliate Program Comparison Calculator & EPC Estimator
Compare up to 3 affiliate programs side by side. Calculate EPC, monthly revenue, and ROI based on commission rate, AOV, conversion rate, and cookie window. Free tool.
Affiliate EPC & Monthly Revenue Formula
Compare affiliate programs using Earnings Per Click (EPC) as the universal benchmark across different commission structures.
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
Enter Program A details
Input the name, commission rate (%), average order value (AOV), and estimated conversion rate for your first affiliate program.
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.
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.
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.
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
"Comparing Amazon Associates (4% commission, $85 AOV, 4% conversion, 1 day cookie) vs. a SaaS affiliate program (30% commission, $99/month AOV, 2% conversion, 90 day cookie)."
Inputs
Result
Amazon EPC: $0.136 → $680/month. SaaS EPC: $0.594 → $2,970/month. SaaS program is 4.4x more valuable per click.
