Estimate Amazon FBA profits: referral fees, fulfillment fees, storage, COGS. Calculate your net margin per unit.
Amazon FBA (Fulfillment by Amazon) is the most popular fulfillment method for Amazon sellers, but calculating true profit can be tricky with so many fee components. This calculator helps you break down every cost and see your real margin, helping you make better product selection and pricing decisions.
Product research - checking if a product is worth selling. Pricing strategy - finding the optimal price point. Cost optimization - identifying which fees eat into profit most. Financial planning - projecting monthly profit at different sales volumes.
Enter your product selling price, product cost, shipping cost to Amazon, and estimated FBA fees. Add referral fee percentage, PPC advertising cost (ACoS), and any other expenses. The calculator shows your total costs, gross profit, net profit, profit margin, and ROI. Adjust any variable to see how it affects your bottom line.
Amazon FBA charges include: referral fee (usually 15% of sale price), FBA fulfillment fee (pick, pack, ship - based on size/weight), monthly storage fee, long-term storage fee (for inventory over 365 days), and removal order fees. PPC advertising is an additional cost.
A healthy net profit margin for Amazon FBA is typically 20-30%. Products under 15% net margin are risky because any increase in PPC costs or fee changes can make them unprofitable. Aim for 25%+ to build a sustainable business.
Gross margin is (Revenue - COGS) / Revenue, covering only direct product costs. Net margin subtracts ALL costs including FBA fees, advertising, returns, and overhead. Net margin is what you actually keep - this is the number that matters most.
ROI (Return on Investment) = Net Profit / Total Investment x 100%. Your investment includes product cost, shipping to Amazon, and any upfront costs. A 100% ROI means you double your money on each unit sold. Most sellers aim for 100%+ ROI on new products.
