How it works
This calculator estimates Amazon fees in a simple, per-order view. The referral fee is a percentage of your selling price. The FBA fulfillment fee is a fixed amount per order based on your product’s size and weight. We subtract these fees plus your product cost and any optional costs to estimate net profit and net margin.
Formula
Example
If price is $40, COGS is $14, referral fee is 15%, fulfillment fee is $5, and other costs are $1: referral fee = $6.00, total fees = $11.00, total cost = $26.00, net profit = $14.00, net margin = 35.0%.
