How Amazon FBA Fees Work

Amazon FBA fees are complex -- far more so than other platforms. Every sale generates at least two charges: a referral fee (a percentage of the sale, which varies by product) and an FBA fulfillment fee (a fixed cost based on size and weight). These typically take 20-35% of your revenue.

Storage Fees

Monthly storage adds another layer of cost. Amazon charges $0.87 per cubic foot from January to September. That rate jumps to $2.40 per cubic foot during peak season (October to December). Items stored over 181 days also face long-term storage fees.

Real Cost Example

A $25 item weighing 1 pound, in a typical category, would have a $3.75 referral fee (15%) and a $3.77 FBA fee -- a total of $7.52. That's 30% of your revenue before accounting for product costs, storage, or advertising. Accurate pricing is important for success on Amazon.

Tips to Protect Your Margins

  1. Source at 1/3 of sale price -- a healthy margin needs roughly three times your initial cost after Amazon takes its share.
  2. Keep items under 1 pound -- FBA fees climb quickly for products over 1 pound.
  3. Watch your storage -- remove slow-moving stock before long-term storage fees kick in after 181 days.
  4. Consider FBM for heavy items -- Fulfillment by Merchant avoids the FBA fee entirely, which matters for bulky products.
  5. Choose your category carefully -- the difference between an 8% and 17% referral fee adds up when you scale.

What percentage does Amazon take?
Amazon's overall fees generally land between 20% and 35% of the final sale price. The referral fee varies: electronics and groceries are 8%, most products are 15%, clothing is 17%, and jewelry hits 20%. FBA fulfillment adds another $3 to $7 for standard-size products.
Are there hidden fees on Amazon FBA?
Amazon makes its fee schedule public, but new sellers often find the details complex. Unexpected expenses usually stem from the FBA fulfillment fee (sensitive to weight and dimensions), monthly storage fees ($0.87 to $2.40 per cubic foot), and penalties for long-term storage over 181 days.
How to reduce Amazon FBA fees?
Aim to source products costing around 1/3 of the eventual sale price to safeguard your profit margins. Keeping items under 1 pound reduces FBA fees. For heavier items, Fulfillment by Merchant (FBM) might be a better option. Remove slow-moving stock before long-term storage fees kick in.
