Amazon deals move prices — and your commission moves with them. Enter the original price, the new sale price, and your rate to see exactly what a drop costs you per sale, and how much more volume you'd need to break even.
Works for any percentage-based affiliate program — Amazon Associates, ShareASale, CJ, Impact, Awin, Rakuten and more. Use your account's actual rate.

Amazon flashes a product on sale and it looks like a win — but you're paid a percentage of the sale price. When a $80 product drops to $60 at a 6% rate, your commission falls from $4.80 to $3.60 per sale. On 50 sales a month, that's $60 gone — and you'd need to sell 67 items (34% more) just to earn the same amount. The calculator tells you in one click whether a deal is worth your traffic.
Amazon Associates pays a percentage of the sale price, so any discount — a Lightning Deal, a coupon, a price-drop alert — reduces your commission on that order. The effect is easy to miss because the rate percentage looks unchanged while the actual dollar amount quietly shrinks. Use this Amazon price drop calculator to convert any discount into real dollars, compare it against your before/after 2026 commission rates, and decide whether the deal deserves a blog post, video, or a share.
Three rules of thumb for affiliates:
Original price and the discounted price. The bigger the gap, the bigger the commission hit.
Use your actual category rate from your dashboard, not an industry average.
The tool shows the per-sale change, your monthly impact, and the volume needed to break even.
A kitchen gadget drops from $120 to $89 — 26% off, tempting. At your 4.5% rate:
Deals convert better than full-price listings — but not always 35% better. Run the numbers before you spend a blog post or a YouTube slot on it. If you're chasing backlinks too, the backlink directory is a free way to grow the traffic side of the equation.
When the extra conversion rate a deal brings can't cover the lower per-sale commission. The tool shows you the exact break-even volume — if you don't think you can reach it, another product or category is a better use of the same traffic.
For percentage-based programs, yes — your commission scales with the sale price. For flat-fee/bounty programs, no, the payment stays the same regardless of price.
The commission calculator shows what you earn at a given price. This tool compares two prices and tells you what a drop costs you and the volume needed to recover it.
For big-ticket items and deep discounts, yes — a 30% drop on a high-value product can erase a meaningful chunk of your monthly earnings. For small, low-priced items it usually doesn't move the needle.
