Understanding Your Affiliate Commissions

Affiliate marketing is a performance-based revenue stream where you earn a percentage of a sale for referring customers to a brand. This calculator helps you forecast your ROI (Return on Investment) based on three primary variables: product price, the commission percentage offered by the affiliate program, and your estimated conversion volume.

How to Calculate Affiliate Earnings Manually

The formula for calculating your affiliate commission is straightforward:

(Product Price × Commission Percentage) × Number of Sales = Total Earnings

Key Metrics to Consider

  • EPC (Earnings Per Click): Measures how much you earn on average for every click sent to the merchant.
  • Conversion Rate: The percentage of visitors who click your link and complete a purchase.
  • Cookie Duration: The window of time you have to earn a commission after a user clicks your link.

Example Calculation

Imagine you are promoting a premium software subscription that costs $150. The affiliate program offers a 30% commission. If you generate 20 sales in a month:

  • Commission per sale: $150 × 0.30 = $45.00
  • Monthly Total: $45.00 × 20 = $900.00
  • Annual Projection: $900.00 × 12 = $10,800.00
