Frequently asked questions
What fees should I include in the Amazon FBA Profit Calculator?
Choose your product category, then include product cost, shipping, FBA fulfillment fee, storage cost and any other per-unit costs that apply to the sale.
How is the Amazon Referral Fee estimated?
The calculator applies Profivexa's shared Amazon category fee rule to your selling price. Actual Amazon fees can differ by exact fee category, program and account.
Does this calculator automatically calculate FBA fulfillment fees?
No. FBA fulfillment fees depend on product dimensions, weight and Amazon rules, so you enter the per-unit amount for your scenario.
How is Break-even Price calculated?
The calculator numerically solves for the selling price where the selected category's referral-fee rule and all entered costs are covered. This accounts for category rules such as minimum, threshold and tiered fees.
What is the difference between profit margin and ROI?
Profit margin compares net profit with the selling price. ROI in this tool follows the existing Profivexa formula and compares net profit with product cost.
Does this calculator include taxes, VAT or GST?
Taxes, VAT and GST are not calculated automatically. Add a per-unit estimate to Other Cost or calculate those obligations separately for your circumstances.
