Amazon Fee Calculator
The Amazon fee calculator estimates your total selling costs including referral fees, FBA fulfillment fees, storage fees, and shipping then returns your net profit, margin, ROI, and break-even price in one view. Enter your product details above to get started.
How does the Amazon fee calculator work?
Enter your selling price and product category to calculate the referral fee, which ranges from 8% to 15% depending on what you sell. Then choose your fulfillment method, FBA or FBM, and fill in the relevant cost fields.
For FBA sellers, enter your product dimensions and weight. The calculator classifies your item into the correct FBA size tier (Small Standard, Large Standard, Large Bulky, or Extra-Large) and applies the current 2025/2026 fulfillment fee automatically.
Add your monthly units sold to convert the storage fee into a per-unit cost, so your profit numbers reflect what you’re actually paying per item shipped.
For FBM sellers, enter your shipping cost to the customer in place of the fulfillment fields.
Once all inputs are filled, the calculator shows the following:
- Total Amazon fees — referral fee plus fulfillment and storage costs
- Net profit per unit — what you keep after all fees and costs
- Profit margin — net profit as a percentage of your selling price
- ROI — return on your unit cost investment
- Break-even price — the minimum price at which you stop losing money
What fees does this Amazon fee calculator include?
Referral fee
- Charged on every sale based on your product category.
- Typically ranges from 8% to 15% of the selling price.
- Automatically calculated based on the selected category.
FBA fulfillment fee
- Covers picking, packing, and shipping by Amazon.
- Based on your product’s size and weight.
- Automatically estimated from the dimensions you enter.
Monthly storage fee
- Charged for storing inventory in Amazon’s warehouses.
- Varies by storage space used and time of year (higher during Q4).
- Included as a per-unit cost in the calculation.
Inbound shipping and other costs
- Includes product cost (COGS), inbound shipping, advertising, and other expenses.
- Added to provide a more accurate profit and break-even estimate.
Are Amazon fees different for FBA and FBM?
Yes. FBA and FBM have meaningfully different cost structures, and the right choice depends on your product, margins, and order volume.
With FBA, Amazon handles storage, fulfillment, and customer service. You pay the FBA fulfillment fee plus a monthly storage fee, but you get Prime eligibility and reduced shipping complexity. FBA tends to work well for lightweight, fast-moving products where the fulfillment fee is competitive with what you would pay to ship yourself.
With FBM, you ship orders directly to customers and pay no fulfillment or storage fee to Amazon, but your shipping costs are entirely on you. FBM can be more cost-effective for heavy, bulky, or slow-moving products where FBA storage fees would accumulate over time.
Use the toggle at the top of the calculator to switch between FBA and FBM and compare your profit under each model.
How to calculate your Amazon break-even price?
Your break-even price is the minimum selling price that covers all your fees and costs without a profit or a loss. The calculator solves this automatically using your inputs.
To find it manually, add up all your fixed per-unit costs, FBA fulfillment fee, storage fee, COGS, inbound shipping, and ad spend, then divide by one minus your referral fee rate.
For example, if your fixed costs total $15.00 and your referral fee rate is 15%, your break-even price is $15.00 ÷ 0.85 = $17.65.
If your current selling price is below that number, you are losing money on every unit. The calculator shows you exactly how far above or below break-even your price currently sits and by how much you would need to raise it to become profitable.
How to calculate Amazon fees manually?
To calculate Amazon fees manually:
- Calculate the referral fee = Selling Price × Referral Fee % (varies by category).
- Add the FBA fulfillment fee based on your product’s size and weight.
- Include storage fees if you’re using Amazon FBA.
- Add your product cost (manufacturing, shipping, packaging, etc.).
- Subtract all costs from the selling price to find your net profit.
Formula:
Net Profit = Selling Price − (Referral Fee + FBA Fee + Storage Fee + Product Cost + Other Expenses)
For faster and more accurate results, you can use an Amazon FBA revenue calculator instead of calculating each fee manually.
Amazon Fee Calculator — FAQs
Amazon seller fees include the referral fee (a percentage of the sale price), the FBA fulfillment fee (for FBA sellers), and the monthly storage fee. Additional costs outside Amazon’s fee structure, such as COGS, inbound shipping, and advertising, are not Amazon fees, but they affect your net profit and are included in this calculator.
Amazon typically reviews and updates its FBA fulfillment fee schedule annually, usually taking effect in February. Storage fee rates are fixed but apply a higher Q4 surcharge from October through December. This calculator uses the current 2025/2026 fee schedule.
Yes. Use the FBA/FBM toggle at the top of the calculator. FBA mode includes fulfillment fees, storage fees, and inbound shipping. FBM mode replaces these with a single shipping-to-customer field.
For FBA: your selling price, product category, unit cost, ad spend, product dimensions (length, width, and height in inches), unit weight in ounces, monthly units sold, and inbound shipping cost. For FBM: selling price, category, unit cost, ad spend, and your shipping cost to the customer.
The calculator applies the published 2025/2026 Amazon fee schedule and standard referral fee rates by category. It does not account for Amazon’s high-volume listing surcharges, aged inventory fees, returns processing fees, or professional seller subscription costs. Use it as a planning tool and verify against your Amazon Seller Central account for final numbers.
