Amazon Affiliate Commission Calculator Guide 2026

"How much do Amazon affiliates make?" is the wrong question. The right one is: how much does a single sale in a specific category actually earn you, in your market, at this moment? The answer changes every time Amazon adjusts a rate — and 2026 brought the biggest adjustments in a decade. This guide shows you the exact math and a free calculator that removes the guesswork.

The 2026 rate picture in one table

Amazon doesn't publish one universal number. Rates are set per category and per marketplace. After the 2026 cuts, most categories sit between 4% and 10%, with a handful unchanged and a few hit hardest (luxury and physical-goods categories dropped up to half). Before any calculation, you need the correct rate for the product's category in your marketplace.

The up-to-date numbers are kept in the Current Rate Table — the same source our calculator and audit use, so you never have to guess.

The commission formula

Commission is computed on the order amount for the referred items, minus any discounts or gift-wrap fees. The formula is:

Commission = eligible order amount × category rate

Example with a 6% rate:

• Product sells for $120 with a $10 coupon → eligible amount $110
• Commission = $110 × 6% = $6.60

Notice the difference from the headline price: quoting "10% of $120" would overstate the payout by a dollar. Small, but it compounds across thousands of orders — which is exactly why underpayment checks matter.

Use the free calculator instead

You can do this by hand for one product, but a site publishes dozens of products across categories. The Commission Calculator takes the price, your category and your market, and returns the exact monthly and per-sale commission using the current rate set — plus it shows the difference from what you'd have earned before the 2026 cuts. That comparison is the fastest way to decide which products deserve a full review page versus a quick mention.

Picking the products worth your time

• High rate + mid price: a 6% rate on a $200 item beats 10% on a $20 item for the same effort.
• Volume matters: two products at 4% that convert daily can out-earn a single 10% product that rarely sells.
• Return risk: a category with a high return rate erodes your commission — the calculator shows gross commission, so mentally discount it for products known to bounce.

Cross-checking your actual payout

The calculator tells you what you should earn. To confirm you're being paid that amount, run the Earnings Audit on your Product Earnings Report CSV. It compares every paid line against the correct rate for its order date and flags anything that comes up short — which is the only reliable defence against silent rate changes in 2026's thinner reporting.
