Amazon FBA Calculator 2026: Accurate Calculation of Profits and Fees (Global Marketplaces)
Have you ever wondered why, despite receiving a ton of orders on Amazon, your bank balance doesn’t increase at the end of the month?
For an Amazon seller, the biggest enemy isn’t the competition but hidden fees. Often, we think we’re making a healthy margin by selling a product for $29.99, but once referral fees, FBA storage costs, and shipping charges are deducted, we’re left with peanuts.
In 2026, selling on Amazon has become more complex than ever. Every marketplace has new rules and dynamic fulfillment costs. To solve this problem, we’ve created this expert-grade Amazon Seller FBA Calculator.
Whether you’re in India searching for the Amazon Profit Calculator India or need data for the US market from the FBA Fee Calculator USA, this tool gives you a second-by-second breakdown.
Expert Insight: “On Amazon, the only one who succeeds is the one who knows every single rupee (or dollar) of their landed cost. If your calculation is wrong, you’re not selling at a profit—you’re selling at a loss.”
Who Is This Tool For?
We’ve designed this Amazon Seller FBA Calculator not just as a math tool, but as a “Business Planner”:
- New Sellers: Who are currently researching products and want to see if a particular niche is profitable.
- Global Expansion Experts: Who want to decide whether their next warehouse should be in the UK or the UAE by comparing Amazon Global Marketplace selling fees.

How to Use an Amazon Seller FBA Calculator: Step-by-Step Guide
Using the Amazon Seller FBA Calculator is very simple. If you are launching a new product or want to check the profitability of your existing product, follow this step-by-step guide:
Step 1: Select Your Marketplace
First, go to the “Amazon Marketplace” dropdown. Here you need to select the country where you want to sell your product (such as the USA, the UK, or India). This will allow the calculator to perform calculations based on that country’s currency and tax rates.
Step 2: Enter the Selling Price
In the “Selling Price” box, enter the price at which you want to sell the product on Amazon.
Tip: Keep in mind that if VAT or GST is included in the price in your country, enter that amount.
Step 3: Fill in Your Costs
1. Product Cost (Landed): Enter the product’s manufacturing cost + the transportation cost from China or the factory to your warehouse.
2. Shipping to Amazon: Enter the cost of shipping from your warehouse to Amazon’s FBA warehouse.
Step 4: Enter Product Weight and Size
Amazon’s FBA fees depend on the product’s weight and dimensions (length, width, height).
1. Weight: If you selected the US, enter the weight in ‘oz’, and for other countries, enter it in ‘grams’.
2. Dimensions: Fill in the product’s Length, Width, and Height so that the correct ‘Size Tier’ can be calculated.
Step 5: Monthly Sales (Optional)
In “Estimated Monthly Sales,” enter how many units you expect to sell per month. This will give the Amazon Seller FBA Calculator a rough idea of the storage fees.
Step 6: Click on Calculate
After filling in all the details, click on the “Calculate Now” button.
How to Understand the Results?
When you click “Calculate,” a results panel will open below:
1. Net Profit: How much money you will have left after deducting all expenses and Amazon fees.
2. Margin (%): What percentage of your total sales is profit? (Above 30% is considered good).
3. ROI (Return on Investment): The percentage return on the money you invested.
4. Total Fees: This includes both Amazon’s referral fee (commission) and FBA handling fee.
Pro Tip: Always plan your profit margin with an extra 2–3% buffer. On Amazon, you sometimes encounter “Unexpected Returns” and “Storage Overages,” and this buffer keeps your business safe.
How an Amazon Seller FBA Calculator Works: The Simple Formula
After all, how does this Amazon Seller FBA Calculator work? It’s very important for a smart seller to know the formula so they don’t blindly trust anything when calculating Amazon ROI online.
The Core Logic: For this, we use the formula given below:
- Referral Fee: This is Amazon’s commission, a fixed percentage on each sale that often reaches up to 15%.
- FBA Fee: This depends on weight and size. It includes Amazon’s picking, packing, and shipping services.
- ROI (Return on Investment): This shows what percentage return you’ve received on the money you invested.
Common Mistakes That Can Cost You Money:
Wrong Weight Category: If your product weighs 12.1 oz, Amazon may charge it in the 1 lb (16 oz) category. Always round up the weight and check.
- Ignoring Referral Fee Variations: Not all categories have a 15% fee; some are 8%, and others can go up to 17%. Our tool uses standard rates, so it’s important to check the category-specific fee.
- Landed Cost Miscalculation: Sellers often only enter the “Buying Price.” Adding customs duties and inspection charges is the real purpose of the Landed Cost Calculator for Amazon.
- Dimensional Weight vs Actual Weight: Amazon always charges based on the greater of the two. If your product is light but bulky, fees will be calculated based on its “Size.”
Real-world Case Studies/Examples
To better understand the calculations, let’s look at two real scenarios that Amazon sellers often have to face.
Case Study 1: The “High Volume” Indian Seller (Home Decor)
Let’s say a seller from India is selling ‘Macramé Wall Hangings’ in the US market.
- Selling Price: $25.00
- Landed Cost: $7.00 (Product + International Shipping)
- Weight: 14 oz (Large Standard Size)
- Analysis: When our Amazon Profit Calculator India–based seller runs the numbers, it shows that after a $3.75 referral fee and about $6.00 in FBA fees, they end up with $8.25 in profit.
- Result: 33% Profit Margin. This is a healthy business model.
Case Study 2: The “Low Margin” Trap (Electronics Accessory)
A seller is selling cheap charging cables in the UK market.
- Selling Price: £8.00
- Landed Cost: £3.00
- Analysis: Despite being a low-cost product, FBA fees (pick & pack) are fixed. After a £1.20 Referral Fee and a £2.50 FBA fee, only £1.30 remains in hand.
- Result: If the PPC (advertising) cost comes to £1 per sale, the seller will be at a loss.
Lesson: When selling low-cost products, it becomes even more essential to calculate Amazon ROI online, because the margin there is very small.

Keep in mind that Amazon revises its inventory storage and fulfillment costs every year, especially during peak seasons.

This will give you the exact information on dimensional weight rules and category-specific referral percentages, which is crucial for your long-term business sustainability.

Frequently Asked Questions
Is this calculator based on the latest 2026 fees?
Yes, our algorithm has been designed with the latest Amazon Seller FBA Calculator 2026 referral and fulfillment structure in mind. However, Amazon updates its fees once or twice a year, so a final check in Seller Central is necessary.
What is the Amazon referral fee?
It’s the commission Amazon charges you for using its platform. Many people ignore it, but according to the Amazon Referral Fee Chart 2026, it can range from 8% to 17% depending on the category.
Should GST/VAT be included in the landed cost?
Absolutely. If you’re selling in India, the GST paid on product purchases and the duties paid at the time of import are part of your landed cost. Ignoring them will give you an inaccurate ROI.
Which is cheaper, FBA or FBM?
It depends on the product’s weight. The simple rule for Amazon FBA vs FBM fees is: for small and lightweight items, FBA is best, but for very large or heavy items, FBM (Merchant Fulfillment) can be cheaper.
What are Monthly Storage Fees?
Amazon charges you a Monthly Storage Fee for storing your inventory in its warehouses. These are calculated on a per-cubic-foot basis. Between October and December, when the holiday season arrives, these fees increase significantly.
Is this calculator accurate for every country?
Yes, our tool has been designed with Amazon Global Marketplace selling fees in mind, taking into account currency conversion and local fulfillment rates.
Who covers the cost of returns?
In FBA, Amazon handles returns, but the seller has to pay the “refurbishing” or “return processing fee.” You should always build a 2–3% extra buffer into your margin for this.
What is the difference between ROI and Profit Margin?
Profit Margin: This tells you what percentage of each sale went into your pocket.
ROI: This tells you how much you earned on the money you invested in the product + shipping.
Disclaimer: These calculations are estimates. Amazon’s official fees may vary based on category, product type, and current policy. Always perform final verification in Amazon Seller Central.
