Amazon FBA Calculator FAQ
Amazon's referral fee is a percentage of the sale price charged for each item sold on the marketplace. It varies by category — typically 8% to 20%. For example, Electronics are 8% while Jewelry can be up to 20%. It is charged on the total sale price including any shipping you charge the customer.
FBA fulfillment fees are per-unit fees Amazon charges to pick, pack, and ship your items to customers. They depend on your product's weight and dimensions. Standard size items under 0.5 lbs start at approximately $3.22 per unit in 2026.
Most successful Amazon FBA sellers target an ROI of 50% or higher (meaning for every $1 invested in product cost, they earn $0.50 net profit). Anything below 25% ROI may not be sustainable after accounting for inventory risks, return rates, and Amazon fee increases.
Yes. You can enter a per-unit monthly storage fee estimate in the "Monthly Storage Fee" field. Amazon charges storage based on cubic feet per month, which varies by season (higher Oct–Dec). Divide your total monthly storage cost by units stored to get a per-unit estimate.
Amazon PPC (Pay-Per-Click) ads reduce your net profit per unit. Enter your average ACoS-derived cost per sale in the ad spend field. A product with a 30% ACoS on a $35 item costs $10.50 in ads per sale — a major factor that many sellers overlook in profit calculations.
