Introduction
The Amazon Revenue Calculator shows you what you really keep from each sale. You type in your price, product size, weight, and costs. It then works out Amazon's referral fee, FBA fee, and storage fee, plus your own costs like product cost, shipping, and ads. You see your net profit per unit, profit margin, ROI, and break-even price.
You can load one of the example products by its ASIN, or just enter the numbers yourself. Fees follow amazon.com's U.S. schedule, in U.S. dollars. It also compares FBA and FBM side by side, so you can see which way of shipping makes more money.
Want to plan ahead? Enter your monthly sales guess and the calculator projects monthly and yearly revenue and profit, plus revenue and profit per seller. Charts show where every dollar of a sale goes and how your profit changes if you raise or lower your price. A step-by-step section shows the math behind each result, so you can check the work and trust the answer before you buy stock.
How to use our Amazon Revenue Calculator
Enter your product details, your sell price, and your costs. The calculator shows your Amazon fees, seller proceeds, net profit per unit, profit margin, ROI, break-even price, and a monthly and yearly revenue projection.
Amazon Marketplace: The calculator uses amazon.com's U.S. fee schedule, in U.S. dollars.
ASIN or Amazon Product URL: Type a 10-character ASIN or paste a product link, then click Look Up Product. The tool fills the fields for the few example products in its built-in catalog; for any other product, type the details by hand. Click Clear to start fresh.
Price (Current and 30-Day Average): Enter the price the item sells for now and its average price over the last 30 days.
Sales Rank (BSR): Enter the current best seller rank and the 30-day average rank. This is a reference number that shows how well the item sells.
Estimated Monthly Sales: Enter how many units the listing sells each month, now and on average.
Use This Data buttons: Click one to send that column's price and sales numbers into the profit and projection panels.
Total # of Sellers: Enter how many sellers share this listing. The tool splits market revenue and profit by this number.
# of FBA Sellers: Enter how many of those sellers use FBA. This shows how much of the listing is FBA.
Fulfillment Mode: Choose FBA if Amazon ships for you, or FBM if you ship it yourself. Both are still compared side by side.
Storage Period: Pick Non-Q4 (January to September) or Q4 (October to December). Q4 storage costs more.
Storage Utilization Ratio: Pick your ratio for the product's size tier, shown on the FBA Dashboard. Professional sellers whose first shipment was more than 365 days ago, with 25 cubic feet or more of stock in the size tier and a ratio above 22 weeks, pay a storage utilization surcharge on stock aged over 30 days.5 It adds $0.44 to $1.88 per cubic foot for standard-size items and $0.23 to $1.26 for oversize items.5 Leave it below 22 weeks if the surcharge does not apply to you.
Product Category: Choose your item's fee category. This sets the Amazon referral fee rate. A product's fee category may not be the same as the category that appears to customers in the Amazon store.1
FBA Fee Table (Apparel rates): Amazon charges FBA fees for apparel from its own fee table.2 The switch turns on when you pick Clothing & Accessories. Turn it off if your item's fee category is not apparel, or on if it is.
Sell Price: Enter the price you plan to charge per unit. All fees and profit are based on this. Amazon charges the referral fee on the total price, including any shipping and gift wrap the buyer pays.1 If you charge buyers for shipping, include it in the sell price.
Package Dimensions (L × W × H): Enter the length, width, and height of the shipping box, then pick the unit. This sets your size tier and FBA fee.
Unit Weight: Enter how much one packed unit weighs and pick the unit. Weight also drives the FBA fee.
Cost of Goods (COGS): Enter what you pay your supplier for one unit.
Product Samples: Enter your sample cost spread over each unit.
Packaging & Labeling: Enter what boxes, bags, inserts, and labels cost per unit.
Shipping to Amazon: Enter your inbound freight cost per unit. This only counts in FBA.
Outbound Shipping: Enter what it costs you to ship one order to the buyer. This only counts in FBM. It is one of your own costs, so it does not lower seller proceeds.
Aged Inventory Surcharge: Enter the surcharge per unit for stock aged 181 days or more. Leave it at 0 if it does not apply.
Overhead / Other Costs: Enter any other cost per unit, like software, returns, or prep help.
Advertising Input Mode: Choose Per unit to enter a flat ad cost, or TACOS % to enter ads as a percent of sales.
Ad Spend per Unit: Enter how much you spend on ads for each unit sold.
TACOS (%): Enter your total ad cost of sales as a percent. The tool turns it into a per-unit cost.
Apply to COGS (landed cost switch): Turn this on if you import your product and want duties, customs, and currency added to your cost.
Import Duties (%): Enter the duty rate charged on your cost of goods.
Customs / Brokerage: Enter customs and broker charges per unit.
Currency Conversion Rate: Enter the rate that turns your supplier price into your selling currency.
Estimated Monthly Sales (units): Enter the unit volume you want the revenue and profit projection to use.
Calculate, Reset, Pin Scenario, Clear Pin: Click Calculate to update the results, Reset to go back to the defaults, Pin Scenario to save a version to compare, and Clear Pin to remove it.
Amazon Seller Revenue and Profit: What You Need to Know
When you sell a product on Amazon, you do not keep the full price a shopper pays. Amazon takes fees out of every order, and you also pay for the product itself, shipping, and ads. Your real profit is what is left after all of that. This page explains the money pieces that decide if an Amazon product makes money or loses it.
The Fees Amazon Charges
- Referral fee: Amazon's cut for making the sale. Most categories are 15%, and the others range from 3% to 45% depending on the category and price.1 Most categories also have a $0.30 minimum per item.1
- Fulfillment fee (FBA): A flat charge per unit when Amazon picks, packs, and ships your order. It grows with the size and weight of the package, and it also depends on whether your price is under $10, $10 to $50, or over $50.2 A 3.5% fuel and logistics surcharge is added to fulfillment fees from April 17, 2026.2 Higher holiday peak fulfillment fees apply from October 15, 2026, to January 14, 2027.2
- Monthly storage fee: Charged per cubic foot for space your stock uses in Amazon's warehouse. Rates are much higher from October to December.5 Some sellers also pay a storage utilization surcharge on stock aged over 30 days.5
- Aged inventory surcharge: The aged inventory surcharge, previously known as the long-term storage fee, is charged on inventory units stored in Amazon's fulfillment network for 181 days or longer.6
- Closing fee: A fixed $1.80 fee on media items: books, DVDs, music, software and video.1
Size Tiers and Billable Weight
Amazon sorts every package into a size tier: Small Standard, Large Standard, Small Bulky, Large Bulky, or Extra-Large.3 The tier plus the weight sets your FBA fee. Amazon does not always use the real weight. For bigger items it compares real weight to dimensional weight (length × width × height ÷ 139) and bills the larger one.4 For Small Bulky, Large Bulky and Extra-Large items, Amazon treats the width and height as at least 2 inches.4 So a light but bulky box can cost more to ship than a small heavy one. Measuring your box correctly is one of the easiest ways to avoid fee surprises.
FBA or FBM
FBA means Fulfillment by Amazon. You ship stock to Amazon, and Amazon stores and ships it. You pay fulfillment and storage fees, and your items can get free, two-day shipping through Prime, which can help increase sales.
FBM means Fulfillment by Merchant. You store and ship orders yourself. You skip Amazon's fulfillment and storage fees, but you pay for boxes, labels, and postage. FBA fees rise with the size and weight of the package, and stock that sells slowly keeps paying monthly storage, so FBM can cost less for large, heavy or slow-selling items. The side-by-side table shows which way costs less for your product.
Your Own Costs
Amazon fees are only half the story. You also need to count the cost of goods (COGS), samples, packaging and labels, shipping stock into Amazon, ads, and overhead. If you import goods, your landed cost is the cost of goods at the currency rate you pay your supplier, plus import duties and customs or broker charges. All of these costs together are your total cost per unit.
The Numbers That Matter
- Seller proceeds: Sale price minus Amazon's fees. This is what Amazon pays out to you, before your own costs.
- Net profit per unit: Proceeds minus every cost you pay. This is your true take-home per sale.
- Profit margin: Net profit ÷ sale price.
- ROI: Net profit ÷ total cost. It shows how hard your cash is working.
- Break-even price: The lowest price you can charge and still not lose money. Know this number before you join a price war or run a sale.
Reading Sales and Competition
Best Sellers Rank (BSR) shows how a product ranks against similar products in the same category, based on its sales.7 A lower BSR number means a better-selling product.7 Sellers use BSR to estimate demand for a product.7 Comparing today's price and BSR to the 30-day average tells you if the listing is on a temporary spike or a steady trend. The number of sellers matters too: total monthly sales split across many sellers means a much smaller slice for you. Offers with fast, free shipping are more likely to win the Buy Box, whether the seller uses FBA or ships orders directly.
Things That Change Your Result
Ad spend can be tracked per unit or as TACOS (total ad spend as a percent of sales), and it pays to watch your conversion rate and click-through rate alongside it. Q4 storage rates, returns, and price drops from other sellers can all turn a thin profit into a loss. Fee amounts also differ by marketplace and currency, and sales tax or VAT rules change by country, so a product that works in the United States may not work in Germany, Japan, or Mexico. Check the numbers for each country you plan to sell in.
