How to Use the Amazon FBA Profit & Fee Calculator
- Enter Your Unit Price & Landed Cost: Input your target selling price and total landed cost of goods (factory price + ocean/air freight).

What Does a Healthy Margin Look Like in 2026?
In modern e-commerce, gross margins must support rising customer acquisition costs. For private label brands on Amazon and Walmart, target a 20% to 30% net margin after all platform deductions and ad spend. For wholesale distributors, aim for 12% to 18%. If your net margin falls below 15%, sudden ad spikes or returns will push your SKU into unprofitability.
Common Mistakes Other Calculators Miss
- Ignoring the Return Rate: Most apparel and consumer goods see 4% to 10% returns. Amazon charges return processing fees and inspection losses.
- Zero Ad Budget Assumption: Organic traffic alone is rarely sufficient at launch. Factoring in 10–15% PPC ad spend prevents negative cash surprises.
- Packaging Creep: A quarter-inch excess in retail box dimensions can bump an item into the higher bulky size tier, doubling fulfillment fees.
Frequently Asked Questions
How are Amazon referral fees calculated?
Amazon charges a percentage referral fee on the total sales price (including shipping charged to the customer). Most categories charge 15%, while electronics and computer items charge 8%.
Why should I include returns reserve and PPC ad spend?
Standard marketplace products experience a 3% to 8% return rate, and driving initial velocity requires 10% to 15% ad spend per unit. Omitting these produces artificially high profit projections.
What is a healthy Amazon FBA profit margin?
