Amazon reduced affiliate commission rates up to 50% in 2026. A category that paid 8% now pays 4% — and the same traffic earns exactly half. On $5,000 of monthly revenue, that's $200 gone every month, or $2,400 a year. The calculator above turns that abstract percentage cut into real dollars so you can plan your content strategy around the categories that still pay.
Amazon Associates pays a percentage of the eligible order amount (product price minus gift-wrap, shipping, and certain taxes). When Amazon changes that rate — which it did across most categories in 2026 — your earnings on the same traffic change instantly. Use this calculator alongside the 2026 commission rate table and the commission calculator to see both the impact of rate changes and your estimated earnings at current rates.
Three things to know about commission changes:
Check the AmzLoss Commission Rates page for the 2026 rate table with pre-cut and current rates by category. You can also look at your Amazon Associates dashboard under the Rate Changes section, or check your earnings report — the rate column shows the rate that applied on each order date.
This calculator estimates the pure rate-change impact on your revenue. Your actual earnings also depend on order volume, product mix, returns, and which rates applied on specific order dates. The AmzLoss Earnings Audit can verify exactly what you were paid versus the applicable rate.
Amazon excludes gift-wrap fees, shipping charges, and certain taxes from the commission base. The "eligible order amount" is the product price minus those exclusions — it is the number your commission rate is applied to.
The Commission Calculator shows what you earn at a given rate. This tool compares two rates and tells you how much the difference costs you in monthly and annual revenue.
It depends on your niche and audience. If you have flexibility, creating content around categories with higher commission rates means more revenue per sale. But don't abandon categories that convert well — a higher-converting 4% category can still outperform a lower-converting 10% one.
