Frequently Asked Questions

Everything you need to know about Amazon FBA fee calculations and profit margins

How does the Amazon FBA Profit Calculator work?
The calculator deducts your Product COGS, Inbound Shipping, Amazon Referral Fees, FBA Fulfillment Fees, Monthly Storage, Returns Reserve, and Advertising Costs (PPC) from your Selling Price to deliver your net profit per unit, profit margin %, and ROI % instantly.
What is Break-even ACoS and why is it important?
Break-even ACoS (Advertising Cost of Sales) represents the maximum percentage of your selling price you can spend on PPC advertising without incurring a net loss on the sale. It equals your profit margin percentage before ad spend.
How are Amazon FBA Referral Fees calculated in 2026?
Amazon referral fees are typically a percentage of your total selling price, averaging around 15% for most standard categories like Home & Kitchen, Toys, and Office, but ranging from 8% for Consumer Electronics up to 17% for Apparel.
What size tier categories determine FBA fulfillment fees?
Fulfillment fees are determined by unit dimensions and shipping weight, classified into Small Standard, Large Standard, Small Oversize, Medium Oversize, and Large Oversize tiers. Rates increase as dimensions and weight grow.
Why should sellers account for a Returns Reserve?
Customer returns incur return processing fees, unsellable inventory disposal/removal costs, and lost initial fulfillment fees. Factoring in a 2% to 5% returns provision ensures realistic margin expectations.
