Affiliate Commission Calculator – Earnings and EPC in 3 Easy Steps
Affiliate Commission Calculator
Use this affiliate commission calculator to find your total earnings, conversion rate and Earnings Per Click (EPC) from campaign traffic.
Use this free affiliate commission calculator to see how much you earn from an affiliate campaign. Enter your clicks, sales and commission terms, either a percentage of each order or a flat amount per sale, and the tool shows your total commission, conversion rate, earnings per click (EPC) and revenue sent to the merchant.
Quick answer
Percentage commission = Sales × Average order value × Commission rate. Flat commission = Sales × Amount per sale. EPC = Total commission ÷ Clicks, and conversion rate = Sales ÷ Clicks × 100. For example, 2,000 clicks and 40 sales of an $80 product at 8% earn $256, a 2% conversion rate and about $0.13 EPC.

Affiliate programs pay in different ways. Amazon-style stores pay a percentage of the order, software and finance offers often pay a flat CPA per signup, and every network reports EPC. Converting all of that into one clear number makes it much easier to decide which offers deserve your traffic.
This affiliate commission calculator does that in one step, whether you are planning a new post or checking last month’s report.
Affiliate Commission Formulas
- Revenue generated = Sales × Average order value (AOV)
- Percentage commission = Revenue × Commission % ÷ 100
- Flat commission = Sales × Flat amount per sale
- Conversion rate (CR) = Sales ÷ Clicks × 100
- EPC = Total commission ÷ Clicks
- EPC per 100 clicks = EPC × 100 (how many networks display it)
How to Use the Affiliate Commission Calculator
Step 1: Enter Clicks, Sales and Commission Terms
Type your Total Clicks / Visitors (2,000) and Total Sales / Signups (40). Choose Percentage (%) per Sale, then enter the average order value ($80) and the commission rate (8%).
Step 2: Read Your Earnings, CR and EPC
Press Calculate Earnings. You earned $256.00 in commission from $3,200 of sales. The conversion rate is 2.00% and EPC is $0.13 per click, about $12.80 per 100 clicks.
Step 3: Compare a Flat-Rate (CPA) Offer
Switch the commission type to Flat Rate ($) per Sale/CPA and enter $25. The same 40 sales now pay $1,000 and EPC jumps to $0.50. This is how you compare a percentage program with a CPA offer on the same traffic.
Percentage vs Flat Commission
| Offer | Terms | Commission on 40 sales | EPC (2,000 clicks) |
|---|---|---|---|
| Retail store | 8% of $80 order | $256 | $0.13 |
| Higher-ticket product | 8% of $250 order | $800 | $0.40 |
| Software trial (CPA) | $25 per signup | $1,000 | $0.50 |
| Finance lead (CPA) | $60 per lead | $2,400 | $1.20 |
Conversion rates differ between offers, so always compare using EPC from your own traffic, not just the headline commission.
What Is a Good Affiliate EPC?
It depends on the niche and traffic source. Many content sites see EPCs between $0.05 and $0.50 for retail offers. Software, hosting and finance offers can reach $1 or more per click. If an offer’s EPC is lower than the value of the same click on another offer or on display ads, swap it.
How to Increase Affiliate Commission
- Raise conversion rate: place links where readers are ready to buy, such as comparison tables and “best” lists.
- Raise order value: promote higher-priced products or bundles.
- Negotiate a higher rate: once you send steady sales, ask the merchant for a better tier.
- Test CPA vs percentage: some merchants offer both; use this calculator to see which pays more.
- Watch cookie length: a 30-day cookie can earn more than a 24-hour cookie at the same rate.
Things That Reduce Real Earnings
- Returned or cancelled orders reversed by the merchant.
- Network fees or minimum payout thresholds.
- Currency conversion and payment fees.
- Paid traffic costs, if you run ads to your links.
