How to Use This Calculator

  1. Enter sale price, product cost, weight, and category.

Formula

Net Profit = Sale Price − Product Cost − Referral Fee − FBA Fee − Storage − PPC

Referral Fee = Sale Price × Category Rate (8–17%)

Example

$25 sale price, $8 cost, 8oz, general category: $25 − $8 − $3.75 − $3.40 = $9.85 profit (39% margin).
