An Amazon FBA calculator estimates your profit on products sold through Fulfillment by Amazon. Enter your selling price, product cost, shipping to Amazon, and the item’s size and weight, and it subtracts referral fees, fulfillment fees and storage fees to show your net profit and margin.
The main fees are the referral fee, a percentage of the sale price that varies by category, and the fulfillment fee, a per-unit fee based on size and weight tier. Storage fees are charged monthly based on the space your inventory occupies, and they’re higher in the fourth quarter. Other costs can include inbound shipping, prep and labeling, advertising and returns.
Example: you sell a product for $25 that costs $6 to make and $1 to ship to Amazon. If the referral fee is 15 percent ($3.75) and the fulfillment fee is about $4.50, your profit before advertising and storage is around $9.75, a margin of about 39 percent. Advertising and returns will lower that number.
Tips: Amazon updates its fees regularly, so always use current fee schedules. Smaller, lighter products usually have lower fulfillment fees. Watch your inventory levels to avoid long-term storage charges, and factor in advertising costs, which can take a big share of profit for new products.
Tips for getting accurate results from the Amazon FBA Calculator: double-check that every input uses the right units, enter numbers without commas or symbols, and run the calculation a second time with a quick estimate in your head to confirm the answer looks reasonable.
How to use the Amazon FBA Calculator on Minedit: enter your values in the fields, press calculate, and review the step-by-step breakdown under the result. If something looks off, change one input at a time to see how it affects the answer, which is also a great way to learn the math behind it.
