Amazon Unit Economics Calculator

Unit economics tells you whether each sale is profitable. Start with your selling price and COGS, then add Amazon's referral fee (varies by category) and FBA fulfillment fee (based on weight).

Return cost spreads the cost of returns across all units. A 2% return rate means you effectively lose 2% of revenue to refunds and restocking. Ad spend per unit is your total monthly ad spend divided by units sold.

Operating profit is before ads; net profit is after. A product can be operationally profitable but lose money once you factor in customer acquisition costs.
