How to Calculate Affiliate Marketing Commissions
Understanding your math is the foundation of a successful affiliate marketing business. Whether you are promoting SaaS products, physical goods via Amazon Associates, or digital courses, knowing your projected revenue allows you to budget for paid traffic and content creation effectively.
The Core Formula
The basic formula used by this calculator is:
Total Commission = (Product Price × Commission Rate) × Total Sales
Key Metrics Explained
Commission Rate: This is the percentage of the sale price the merchant pays you. Digital products typically offer 30-70%, while physical goods often range from 1-10%.
EPC (Earnings Per Click): This measures the average value of every visitor you send to a merchant. It is calculated by dividing total commission by total clicks.
Conversion Rate: The percentage of your traffic that actually makes a purchase. If 1,000 people visit your link and 10 buy, your conversion rate is 1%.
Real-World Example
Imagine you are promoting a high-end VPN service:
Product Price: $120.00
Commission Rate: 40%
Sales: 25 per month
Calculation: $120 × 0.40 = $48.00 per sale. Multiply $48.00 by 25 sales = $1,200.00 total monthly income.
Strategies to Increase Your Earnings
Once you see your numbers in the calculator, you can focus on two levers: volume and conversion. If your commission rate is fixed, focus on increasing your Conversion Rate (CR) through better pre-selling content, or increasing your Traffic Volume through SEO and social media.
