How the numbers shift across typical situations for this calculator:
| Scenario | Affiliate commission | Net to merchant |
|---|---|---|
| 10% of $5,000 | 500 | 4,500 |
| 30% of $1,000 (digital) | 300 | 700 |
| 4% of $25,000 (Amazon) | 1,000 | 24,000 |
| 50% of $497 (course) | 248.5 | 248.5 |
How This Calculator Works
Enter referred sales and the commission rate. The calculator multiplies the two to give the affiliate's commission and shows the merchant's net. Affiliate rates vary enormously by category — physical goods often 4% to 8%, digital products 20% to 50%, info products and high-margin courses 50%+.
The Formula
Percentage of an Amount
Amount is the base value, Percentage is the rate applied to it
Worked Example
A 10% commission on $5,000 of referred sales pays the affiliate $500 and leaves $4,500 for the merchant. Across a year, a productive affiliate driving $50,000 of monthly sales at 10% earns $60,000 — a meaningful side income or full-time business for established affiliates.
Key Insight
Affiliate commission rates are inversely correlated with product margin. Amazon's 1% to 4% rates fit razor-thin retail margins; SaaS at 30% to 50% lifetime commissions fits 80%+ gross margins. The highest-paying affiliate programs (digital courses, premium SaaS) work because the merchant's marginal cost per additional sale is near zero — every percentage point on top of marketing spend is still profitable.
Frequently Asked Questions
How is affiliate commission calculated?
Multiply referred sales by the commission rate. A 10% commission on $5,000 of sales pays the affiliate $500, leaving $4,500 for the merchant.
What is a typical affiliate commission rate?
Physical goods (Amazon, retail): 1% to 8%. Digital products and SaaS: 20% to 50%. Info products and online courses: 30% to 60%. Recurring SaaS commissions can be lifetime or first-year-only.
Are affiliate commissions taxable?
Yes — as self-employment income for the affiliate. US merchants issue 1099-MISC for affiliates earning $600+ in a year. Set aside 25% to 35% for tax (federal + self-employment + state).
What is a tiered commission?
Rates that increase with volume — for example, 10% on the first $5k of monthly sales, 12% on the next $10k, 15% above that. Tiered programs reward high-volume affiliates and need to be calculated tier by tier.
Recurring vs one-time commissions?
Recurring commissions pay each month the customer stays (typical for SaaS). One-time commissions pay once on the initial sale. Recurring commissions usually compound to higher lifetime value if affiliate keeps referring users who stay.

Methodology & Review
Commission is referred sales multiplied by the commission rate; the remainder is the merchant's net of commission. The calculator models a single flat rate; tiered programs (rates that increase with volume) and recurring-commission programs (monthly cuts on subscriptions) need to be calculated tier by tier or month by month.
