Affiliate Marketing Commission & Earnings Calculator

Affiliate Marketing & Performance Publishing: EPC vs. Payout Rates

• Earnings Per Click (EPC): The gold standard metric for evaluating affiliate programs). A 50% commission offer with a 0.5% conversion rate often delivers a lower EPC than a 15% commission offer with an 8% conversion rate.

• Refund & Clawback Protection: High refund rates can wipe out up to 10%–20% of affiliate earnings; factoring in net returns prevents overestimating ad spend when running paid arbitrage campaigns.

• Recurring SaaS Affiliates: Promoting monthly subscription software (20%–30% lifetime recurring commissions) creates compounding recurring revenue cohorts that grow over time.

How to Use This Calculator

The Formula

Affiliate Marketing \& EPC Monetization equations:

Gross Referrals = Monthly Clicks × Conversion Rate (\%)

Net Qualifying Sales = Gross Referrals × (1 - Refund Rate)

Commission Per Sale = Average Order Value (AOV) × Commission Rate (\%) or Fixed CPA

Net Monthly Commission = Net Qualifying Sales × Commission Per Sale

Earnings Per Click (EPC) = (Net Monthly Commission) / (Total Referral Clicks)

Worked Example

For example, an affiliate driving \ to a product converting at 3.50\% (280 gross sales) with a 5.0\% refund rate (266 net sales), \120.00 AOV, and 20.0\% revenue share): The Net Monthly Commission is \), delivering an Earnings Per Click (EPC) of \.

Understanding Your Result

Marketing metrics are most useful as trends over time rather than isolated snapshots. Benchmark your result against your own historical performance first, then against industry averages. Attribution models (last-click vs. multi-touch) can produce dramatically different channel ROI figures — ensure consistent attribution methodology before making channel budget decisions. Statistical significance requires sufficient sample size: most A/B test decisions need a minimum of 1,000 conversions per variant for reliable results.
