How to Calculate Amazon FBA Profit
To determine your true profitability as an Amazon FBA seller, you need to account for all costs: product cost, shipping to FBA, FBA fulfillment fees, Amazon's referral fee, and any additional expenses like advertising or returns. Our Amazon FBA profit calculator automates this process, giving you instant net profit, profit margin, and ROI. Simply input your numbers and adjust variables to see how pricing changes affect your bottom line.
- Selling Price: Your final price on Amazon (including VAT if applicable, but we use net price for US/EU).
- Product Cost: Landed cost per unit from your supplier.
- Shipping to FBA: Freight, customs, and delivery to Amazon fulfillment centers (per unit).
- FBA Fulfillment Fee: Amazon's fee for picking, packing, and shipping to the customer.
- Referral Fee: Category-based percentage (e.g., 15% for most categories).
- Other Fees: PPC ads, return processing, storage, or promotional discounts.
Use this FBA profitability tool to evaluate product ideas, optimize pricing strategies, and avoid selling at a loss. All calculations are done locally — no data is sent to any server.
Understanding FBA Profit Margin & ROI
- Net Profit = Selling Price - (Product Cost + Shipping + FBA Fee + Referral Fee + Other Fees)
- Profit Margin (%) = (Net Profit / Selling Price) × 100 – a healthy margin for FBA is typically 15-30%.
- ROI (%) = (Net Profit / (Product Cost + Shipping Cost)) × 100 – measures return on your initial investment. Many sellers target 30-50% ROI.
For European sellers: remember to account for VAT if you are not registered for OSS. This calculator focuses on pre-tax profit. Adjust your selling price accordingly.
