Amazon India FBA Calculator: Profit, Fees & GST

Amazon India FBA profit calculator: how profit and margin are worked out

The result panel shows net profit per unit ordered. It is an expected value: some of the units you sell come back, and a returned order costs money in a different way from a kept one, so the calculator works out both and weights them by your return rate.

• Net margin is net profit divided by the selling price without GST. GST is collected for the government, so it is not part of your revenue.
• Net ROI is net profit divided by your landed cost: the product price plus shipping and duties per unit.
• Profit if nothing is returned is the profit on a unit that is sold and kept. The gap between this and net profit is what returns cost you.
• Break-even TACoS is the most you can spend on ads, as a share of price, before the product stops making money.
• Break-even selling price is the lowest price at which net profit is zero, with your other inputs held fixed.

The coloured band under the profit figure reads the net margin: Great at 40% or more, Good from 25%, Acceptable from 15%, Riskier from 10% and Risky below that. It is a rule of thumb for a quick read, not a verdict on a product.

Referral, closing and FBA fees explained

Amazon India charges FBA sellers several fees on each unit. The calculator works them out from your category, price, size and weight, and adds GST on top. You can override any of them.

• Referral fee: a percentage of the GST-inclusive selling price. It depends on the category and usually changes with the price band, so a small price change can move you into a very different rate.
• Closing fee: a fixed amount per unit sold. It depends on the price band and, for some categories, a fee group.
• Weight handling fee: a per shipment fee for FBA delivery, set by the chargeable weight, where the order ships and your STEP level. Chargeable weight is the higher of actual weight and volumetric weight (length × width × height in cm, divided by 5,000).
• Pick and pack fee: a fixed amount per unit sold that grows with weight.
• Storage fee: a monthly charge per cubic foot of space your stock occupies, so small products cost far less to store.

For example, the calculator's starting category, Kitchen - Other Products, pays 0% up to ₹1,000, 12.5% above ₹1,000.

These come from the Amazon India fees and pricing page, which describes its figures as indicative. Check them against your own rate card before you rely on them. This version covers FBA from the fulfilment centre, with 234 categories. Easy Ship, Seller Flex and self-ship are not supported yet.

How GST, TCS and TDS affect your Amazon India payout

GST changes the maths in three places, and a calculator that ignores them overstates or understates profit.

• On the sale. The price includes GST. You collect it and pass it on, so only the part without GST is your revenue.
• On your costs. The GST on your supplier invoice, shipping and duties is input tax credit. If you can claim it, it offsets the GST you owe, so the real cost of the product is the amount without GST.
• On Amazon's charges. Amazon adds GST to its fees, storage and ad invoices. This is also claimable as input credit.

When your input credit is larger than the GST you collected, the GST ledger in the results shows a credit balance. In the sample below it is ₹37.89 per unit, which carries forward against future GST you owe. If you cannot claim input credit, switch the toggle off and every GST amount becomes a cost.

TCS and TDS. Amazon withholds tax collected at source and tax deducted at source from your payout. Both are adjusted against your tax liability later, so they change when you receive cash, not how much you earn. This calculator does not model them. Rates change, so confirm the current ones with your CA before you plan cash flow around them.

Amazon revenue calculator vs this calculator

Amazon's own Revenue Calculator in Seller Central is the right place to confirm the exact fees for a specific listing. Sellers searching for an "Amazon revenue calculator" or "Amazon calculator" usually want that, and it is worth using for the fee amounts.

This calculator starts from those fee amounts and goes further down the page to what you actually keep:

• Advertising, entered as TACoS or as rupees per unit, with a break-even TACoS.
• Returns, with a sellable and unsellable split, your own handling cost and the stock you write off.
• GST on your costs and on Amazon's charges, with input credit switched on or off.
• A break-even selling price, so you know the floor before you cut a price.

A sensible workflow is to copy the fee amounts from Amazon's tool into the fee fields here, then add your own costs.

How to use the calculator

1. Enter the selling price as customers see it, GST included, and pick the product's GST rate.
2. Enter your cost per unit from the supplier invoice, the purchase quantity and the total shipping and duties for that purchase.
3. Pick your category, then enter the packed size and weight of one unit. The referral, closing, weight handling, pick and pack and storage fees fill in from Amazon India's rate card.
4. Set storage months, your TACoS and your return rate. Use your own history if you have it, and a cautious guess if you do not.
5. Read the net profit, margin and break-even figures. Change one input at a time to see what moves them most.
6. Copy the page address to keep or share your numbers. Nothing you type is saved on our servers.

Worked example

The calculator opens with a sample product so you can see every step. It is an illustration, not a forecast or a real listing: a made-up product in the Kitchen - Other Products category priced at ₹1,299 with 5% GST, bought at ₹193.20 a unit plus ₹135.00 of shipping and duties, 15% TACoS and a 9% return rate.

• Without the GST, the sale brings in ₹1,237.14.
• After product cost and Amazon fees, gross profit is ₹625.20, a gross margin of 50.5%. This is the number many sellers stop at.
• Storage and advertising take that down to ₹457.24 on a unit that is kept.
• Returns cost another ₹91.51 per unit ordered, leaving ₹365.73 of net profit, a 29.6% net margin.

The gross margin looks far healthier than the net margin. The difference is advertising and returns, which is why the calculator includes both.

Common mistakes that make FBA products look more profitable than they are

• Leaving out ads. New products often need heavy ad spend. Put your real TACoS in, not the one you hope for.
• Treating a return as a refund only. You may lose the fees, the ad spend and, for unsellable units, the product itself.
• Mixing GST-inclusive and GST-exclusive numbers. Compare like with like. Selling price and most invoices include GST, margins should not.
• Assuming input credit you cannot claim. If your supplier is not GST registered or you are on the composition scheme, turn the toggle off.
• Forgetting storage. A slow seller sits in the warehouse for months. Raise the storage months for slow movers and for stock sent before the festive season.
• Using the wrong size tier. A small change in packed size or weight can move a product into a dearer FBA fee tier. Measure the packed unit, not the product.
• Spreading shipping over the wrong quantity. Divide the freight and duties by the units in that shipment, not by an annual forecast.
