This Amazon Fee Calculator helps sellers estimate their profit after Amazon charges. Amazon takes a referral fee for each sale, and if you use Fulfillment by Amazon (FBA), fulfillment fees also apply. Enter your product price, product cost, and fees to quickly estimate your profit and profit margin before listing your product.
The most common mistake new Amazon sellers make is pricing a product based on what feels right rather than what the numbers actually support. A product selling at $30 with a $12 cost feels profitable — until you account for Amazon's referral fee, FBA fulfillment charges, and shipping costs, and discover the actual profit is $1.80 per unit. Our free Amazon fee calculator puts every cost on the table instantly so you know your real margin before you commit to a product or a price.
Enter five values and the calculator produces six outputs that cover every dimension of Amazon selling profitability.
The referral fee Amazon charges on each sale, calculated as a percentage of your selling price. This goes directly to Amazon and cannot be avoided on any sale made through the platform.
The sum of everything you spend to make one sale — your product cost, shipping cost, FBA fee, and Amazon's referral fee combined. This is the complete outgoing amount per unit.
What remains after all costs are subtracted from the selling price. This is the number that determines whether a product is worth selling. If it is negative, the product loses money on every sale.
Net profit expressed as a percentage of the selling price. A margin of 20% means twenty cents of every dollar in revenue is actual profit. Experienced Amazon sellers typically target a minimum margin of 15 to 20% for FBA products to account for returns, advertising costs, and storage fees that this calculator does not include.
Return on Investment measures profit relative to the product cost — how much you earn back for every dollar you invest in inventory. An ROI of 50% means for every $100 spent on product, you earn $50 in profit. ROI is often more useful than margin for evaluating sourcing decisions and comparing product opportunities.
The minimum selling price at which you cover all costs and make exactly zero profit. Knowing this number tells you how much pricing flexibility you have — how far you can drop the price in a promotion, a price war, or a liquidation scenario before you start losing money.
Amazon charges sellers in several distinct ways, and understanding each one is essential for accurate profit calculation.
Referral fees
Amazon's core commission, charged as a percentage of the total selling price including any gift-wrap charges. They vary significantly by category — Books carry 8.5%, Electronics accessories carry 15%, Clothing and accessories carry 17%, Jewellery can reach 20%. If you are selling across multiple categories, the referral fee percentage needs to be adjusted for each product type.
FBA fees
Cover the cost of Amazon storing, picking, packing, and shipping your product to the customer. What you actually pay depends on how your product is classified in Amazon's size tier system — a small standard item and a large bulky item sitting at the same weight can carry fees that differ by several dollars. FBA fees are updated by Amazon periodically, so always check the current fee schedule before finalising your calculations.
Shipping cost to Amazon
The cost you pay to send your inventory from your supplier or warehouse to Amazon's fulfillment centers. This is separate from the FBA fee. For sellers sourcing from overseas manufacturers, this cost can be significant and varies by shipment size, weight, and shipping method.
Net Profit — go/no-go decisions
Before sourcing any product, calculate net profit per unit at your target selling price. If it does not clear your minimum threshold after accounting for advertising, reconsider the product or renegotiate the source price.
Profit Margin — compare products
Two products with the same net profit per unit are not equally attractive if they sell at different prices. Margin normalises this comparison — a $5 profit on a $25 product (20%) is better than a $5 profit on a $50 product (10%) because the capital tied up is proportionally less.
ROI — evaluate sourcing decisions
When deciding between products or suppliers, ROI on product cost is the clearest metric. A 100% ROI means you double your money. For Amazon sellers who reinvest profits into inventory, a higher ROI compounds faster.
Breakeven Price — competitive strategy
When a competitor drops their price, your breakeven tells you the floor. Anything above it generates profit. Anything below it loses money. If a competitor prices below your breakeven, the product may not be viable at your current cost structure.
Being honest about limitations makes this tool more useful, not less.
This calculator does not include Amazon's monthly selling plan fee ($39.99 for a Professional account). It does not include storage fees, which Amazon charges per cubic foot of inventory stored in their warehouses and which increase significantly during the fourth quarter. It does not include advertising spend — Sponsored Products, Sponsored Brands, and display ads — which for many categories represents the largest variable cost after Amazon's fees. It does not include return processing fees, which apply when a customer returns an FBA product.
For a complete profitability picture, add your estimated monthly advertising spend divided by monthly unit sales to the per-unit cost, and add average storage fees similarly. The outputs from this calculator represent your baseline profitability before these additional variable costs.
Target a minimum 20% margin before advertising costs
This leaves enough room for ad spend, returns, and occasional price adjustments without pushing you into negative territory.
Verify the current FBA fee for your specific product
Amazon updates FBA fees periodically and the changes can significantly affect profitability for products in certain size tiers. Always check the current fee schedule before listing.
Use breakeven as your floor for promotions
Pricing below your breakeven in a lightning deal or coupon costs you money on every unit sold — which can make sense for launch velocity but should always be a deliberate decision, not an accident.
Check the referral fee for your specific category
The default 15% applies to many categories but not all. Using the wrong rate produces inaccurate results — always verify on Amazon Seller Central before calculating.
Recalculate whenever your costs change
Supplier price increases, new shipping rates, and FBA fee updates all shift your breakeven and margin. A product that was profitable at launch can become marginal without you noticing if you do not recalculate regularly.
An Amazon fee calculator is a tool that helps sellers estimate Amazon fees, including referral fees, FBA charges, and total costs to calculate profit and margin.
Amazon seller fees are calculated by adding referral fees, FBA fulfillment fees, shipping costs, and product cost, then subtracting them from the selling price.
The Amazon referral fee is a commission Amazon charges on each sale, usually between 8% and 20%, depending on the product category.
FBA fees cover storage, packing, and shipping handled by Amazon. The cost depends on product size, weight, and category.
To calculate Amazon FBA profit, subtract product cost, shipping, referral fee, and FBA fee from the selling price.
A good profit margin on Amazon is typically 15% to 30%, depending on competition, category, and advertising costs.
Amazon ROI is calculated by dividing profit by product cost and multiplying by 100 to get the percentage return on investment.
Breakeven price is the minimum selling price where total revenue equals total cost, meaning no profit or loss.
Yes, Amazon charges a monthly subscription fee for Professional seller accounts, along with per-sale and fulfillment fees.
FBA fees are worth it for many sellers because Amazon handles storage, packing, shipping, and customer service, saving time and effort.
