Amazon Seller Profit Calculator
See what actually reaches your bank after every Amazon fee and GST.
Enter your listing price and costs. We will apply every Amazon deduction, the 18% GST charged on those fees, your input tax credit and your return rate, to show what you really earn per order.
The fee stack sellers forget
Four deductions come out of every order: a referral fee that is a percentage of the total selling price, a closing fee that varies by price band, a shipping or weight-handling fee, and 18% GST charged on the sum of all those fees. Sellers who model only the referral fee routinely overestimate profit by fifteen percent or more.
GST on fees is claimable — if you are registered
Amazon charges 18% GST on its own fees. A GST-registered seller claims this back as input tax credit, so it is not a real cost. An unregistered seller absorbs it entirely. That single difference can decide whether a thin-margin product is viable at all, which is why registration status is a field here.
Returns cost more than the refund
Amazon refunds the referral fee on a returned order, but shipping and handling charges are usually not recovered, and the unit may come back unsellable. Enter a realistic return rate for your category — apparel commonly runs far higher than electronics — and the profit figure becomes something you can plan around.
Know your break-even listing price
The calculator gives the GST-inclusive price at which the order earns exactly nothing. Keep it in mind before you join a sale event or match a competitor's price, because a discount that dips below it converts every extra sale into a larger loss.
Check your rate card
Referral percentages differ by category and often by price band within a category, and Amazon revises them. Pull the current numbers from Seller Central rather than relying on a figure you memorised last year.
