Amazon Repricing Calculator
Whether the volume covers the thinner margin.
Amazon revises fee schedules at least annually and adds new surcharges more often. These defaults are a starting point — the figures in your own fee preview are the ones that describe your ASINs.
Profit change
−$493
18% volume for -10% price
The price cut loses $493 a month. Volume would have to rise 39.8% just to stand still, which implies an elasticity well above the 1.8 entered.
How the Amazon Repricing Calculator works
A price cut only works if the extra volume more than covers the thinner margin, and that depends on elasticity — a number most sellers assume rather than measure. Getting it wrong loses money confidently, because the volume goes up and the profit goes down.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
How do I know if a price cut will pay?
Model the volume increase your elasticity implies and compare total contribution before and after. On thin margins the required volume increase is much larger than intuition suggests.
What is price elasticity?
The percentage change in units for a one percent change in price. An elasticity of 1.8 means a 10% price cut sells 18% more units. Above 1 the product is elastic; below 1 a price cut reduces revenue.
How do I measure it?
A controlled test — change price, hold everything else constant including advertising, and measure over enough days to clear noise. Rank effects lag, so a week is usually the minimum useful window.
Should I use automated repricing?
For competitive commodity listings, yes, with a hard floor set from your own costs. Automated repricers without a properly calculated floor are one of the more efficient ways to lose money at scale.
