How to Calculate Affiliate Commission
Understanding your earnings as an affiliate marketer is crucial for scaling your business and choosing the right programs. Most affiliate programs pay based on a percentage of the total order value, while others offer a flat fee per lead or sale.
The Formula:
The basic formula for a percentage-based commission is: Total Earnings = (Total Sales Volume × (Commission Rate / 100)) + Fixed Bonuses
Realistic Example
Let's say you are promoting a fitness equipment brand. In one month, you drive 20 sales totaling $4,000 in revenue. The brand offers a 12% commission rate and a $50 bonus for exceeding 15 sales.
Base Commission: $4,000 × 0.12 = $480
Bonus: $50
Total Earnings: $480 + $50 = $530
Average per Sale: $530 / 20 = $26.50
Key Factors Influencing Your Commissions
1. Cookie Duration: The "cookie life" determines how long after a click you can still earn a commission. A 30-day cookie is standard, but some programs offer 90 days or even lifetime attribution.
2. Conversion Rate (CR): No matter how high the commission percentage is, if the traffic doesn't convert, you won't earn. Aim for products with proven high conversion rates.
3. Average Order Value (AOV): Percentage-based commissions rely heavily on how much the customer spends. High-ticket items (over $500) can yield massive commissions even with lower percentages.
4. Refund Rates: Remember that most affiliate programs deduct commissions for returned items or refunded services. Always check the "net" commission after potential returns.
