Affiliate Commission Modeler

Setting affiliate commission rates is one of the most common pricing mistakes DTC brands make. Set it too low and no one promotes you. Set it too high and every affiliate sale eats your margin. This calculator works backwards from your unit economics to determine the maximum commission you can afford while maintaining your target profit margin.

The math starts with your AOV, subtracts COGS and fulfillment costs to get your contribution margin, then reserves your target minimum profit percentage. Whatever is left is the maximum you can afford to pay in commission. The comparison table shows how different commission rates affect your margin per sale, making it easy to pick a rate that balances affiliate attractiveness with profitability.

Industry benchmarks for ecommerce affiliate commissions range from 5% to 20% depending on category and margin structure. Beauty and supplements with 70%+ margins can afford 15 to 20%. Apparel with 50 to 60% margins typically offers 8 to 15%. Electronics with 15 to 30% margins are limited to 3 to 8%. The key insight is that your commission rate should be derived from your actual margins, not copied from competitors who may have different cost structures.

Consider tiered commission structures to incentivize top performers: 10% base rate for all affiliates, 12% for those generating over 50 sales per month, 15% for over 100. This rewards volume without overpaying your long tail of low-volume affiliates. Also factor in that affiliate customers often have lower LTV than direct customers — they came for a deal and may be less brand-loyal — which argues for slightly conservative commission rates until you have data on affiliate customer retention.
