Amazon FBA price calculator
What to charge on Amazon to keep the margin you want. Enter what a unit costs you landed, its packaged size and weight, its category and the share of the price you spend on ads: the calculator works backwards through Amazon's 2026 referral and FBA fees to the lowest price that leaves your margin, your breakeven price, and what you keep at the next .99.
How it's worked out
- What Amazon takes depends on the price: the referral fee is a share of it (in some categories the share changes with the price, and there's a $0.30 minimum), and the FBA fee for your size tier is lower under $10 and higher over $50.
- The price for your margin is the lowest price where price − referral fee − FBA fee − ads − landed cost − other costs is at least your margin × the price. The calculator tries every price, cent by cent, with Amazon's 2026 fee tables.
- Breakeven is the lowest price where nothing is lost.
In the example, the referral fee is $3.57, the FBA fee $5.61 and the ads $2.38 at $23.82: with the $6.00 landed cost and $0.30 of other costs, $5.96 is left, 25.0% of the price. It breaks even at $15.88; at $23.99 the margin is 25.3%.
Pricing questions
Should I count ads in my price?
Yes, if you advertise: ads are a cost of every sale they bring, and spread over all your sales (TACoS) they're a share of every price. The ACoS calculator works out your TACoS and breakeven ACoS.
Is $9.99 better than $10.99?
Sometimes: under $10 Amazon charges a lower FBA fee, and in some categories a lower referral rate, so a dollar off can cost less than a dollar. The Small and Light replacement guide works two examples out.
What else should the margin cover?
Returns, storage, the low-inventory-level fee in thin months, reimbursements Amazon doesn't pay: the real profit guide lists them, and the profit calculator checks one price with all of them.
