How to use this calculator
Enter your product selling price, landed product cost, Amazon referral fee rate, and advertising cost per order. The calculator estimates per-order profit, margin, and monthly profit using a default fulfillment and return allowance.
What the result means
A higher result means each order creates enough contribution after Amazon fees and acquisition costs. Low or negative profit means the item needs better sourcing, repricing, lower ads, or a different fulfillment strategy.
Profit per order = Selling price − Product cost − Amazon referral fee − fulfillment allowance − ad cost. Net margin = Profit per order ÷ Selling price × 100.
This estimate uses a standard fulfillment allowance, so sellers with exact FBA fees should also compare the result against their Seller Central fee preview.
