📘 How to Calculate Amazon FBA Profit
Your Amazon FBA net profit = Sale Price - COGS - Fulfillment Fee - Referral Fee. Understanding each component is key to a profitable FBA business.
How much does Amazon FBA take per sale?
Amazon charges a referral fee (typically 15% for most categories) plus an FBA fulfillment fee ranging from $2.47 to $9+ depending on product size and weight. Together, Amazon fees average 25-35% of your sale price.
What is a good profit margin for Amazon FBA?
Most successful FBA sellers target 20-30% net profit margin after all costs including PPC ad spend. Below 20% leaves little room for returns, storage, and competition-driven price cuts.
How to account for storage fees in FBA costs?
Monthly storage fees range from $0.75-$2.40 per cubic foot (higher in Q4). Divide monthly storage by your sell-through rate to get the per-unit cost. Fast-turning inventory minimizes this cost.
What FBA fee changes happened in 2026?
Amazon adjusts fulfillment fees annually. Always verify current rates in Seller Central's Fee Preview tool before sourcing new products. This calculator uses 2026 standard rates as defaults.
