eBay profit calculation, step by step: everything to subtract from a sale in the UK and US

How does an eBay profit calculation work?

An eBay profit calculation works backwards from the money the buyer paid. You take off everything eBay charges, everything the item cost you to get to the buyer, and an allowance for the orders that go wrong. The figure left is your profit before income tax. Do it once by hand for a typical sale and you will understand your prices far better than any calculator can explain them.

The order of steps matters because several eBay fees are a percentage of the total sale, not of your item price. If you work them out on the wrong base, every answer after that is wrong too.

Step 1: what did the buyer pay in total?

Write down the total amount of the sale. That is the item price plus any postage you charged. On eBay.com it also includes the sales tax that eBay collects from the buyer, even though that tax does not stay with you.

This total matters because eBay's main fees are worked out on it. On eBay UK, the business seller fee page describes the total amount of the sale as including the item price, postage and any applicable taxes. On eBay.com, eBay's seller fees page says the final value fee is calculated on the total amount of the sale, including the cost of the item, shipping, sales tax and other applicable fees.

Step 2: which eBay fees come off every sale?

For most business sellers, three or four eBay charges apply to every order.

The UK figures are from eBay UK's fees for business sellers, which also says its fees are shown excluding VAT. UK private sellers are different: eBay UK says UK-based private sellers pay no final value fee and no regulatory operating fee when items sell, Motors vehicles excluded.

For Promoted Listings general campaigns, eBay UK says you pay only when the promoted item sells within 30 days of a click on the ad, and the fee is the ad rate as a percentage of the total sale amount, including item price, postage and taxes, at the rate in effect at the time of sale.

Step 3: are there international or currency charges?

Some sales carry extra charges, so check these before you call the calculation finished.

• International fee, eBay.com: eBay says US-registered sellers pay an international fee when the delivery or buyer address is outside the US. eBay's export site gives it as 1.65% of the total sale, and says sellers using eBay International Shipping pay no international fee on eligible items.
• International fee, UK private sellers: a UK private seller pays a 3% international fee when delivering overseas.
• Currency conversion: eBay's seller currency conversion charge is 2.5%, rising to 2.75% from 1 December 2026. It applies where eBay converts money between currencies for you. Our guide to the eBay currency conversion charge explains when.
• Below Standard surcharge: if your account is Below Standard at an evaluation, eBay adds extra percentage points to final value fees for the following month, on both sites.

Step 4: what did the item cost you to deliver?

Now take off everything you paid to get the item to the buyer.

• Item cost: what you paid your supplier, including any VAT you cannot reclaim.
• Delivery: the postage label, or the delivery charge your supplier added.
• Packaging: boxes, bags, tape and labels, averaged per order.
• Payment or card fees on your supplier purchases, if any.

If you buy stock in bulk, divide the whole landed cost, including freight and import charges, by the number of units you received.

Monthly costs such as an eBay shop subscription, software and storage do not belong to any one order, but they still have to be paid from your sales. Divide the monthly total by your usual number of orders a month and include that figure as one more line. Leaving it out makes every listing look a little more profitable than it is.

Step 5: what allowance should you make for problem orders?

Some orders lose money: a refund, a return you paid postage for, a lost parcel, a partial refund for a minor fault. These are real costs even though they do not appear on the order that made the profit.

Total up those losses over the last three or six months and divide by the number of orders in the same period. That gives an average cost per order. Take it off every sale in your calculation. If you are new and have no history, start with a small, cautious figure and replace it with your own number after a few months.

Two worked examples of an eBay profit calculation

Example 1: eBay UK business seller

Example, with hypothetical numbers: suppose you sell an item for £25.00 with free postage. For the arithmetic, assume a final value fee of 13% (a hypothetical rate; check your category on eBay's fee page) and a 2% ad rate.

1. Total sale: £25.00.
2. Final value fee at 13%: £3.25.
3. Regulatory operating fee at 0.35%: £0.09.
4. Per-order fee (order over £10): £0.40.
5. Ad fee at 2%: £0.50.
6. Item cost from your wholesale supplier: £13.00, and delivery to the buyer: £2.50.
7. Problem order allowance: £0.50.

Profit: £25.00 minus £20.24 = £4.76, before income tax. If you are VAT registered, part of the £25.00 is VAT you owe to HMRC, so your real figure is lower; work out VAT separately with your accountant, and see our guide to VAT on eBay fees.

Example 2: eBay.com seller

Example, with hypothetical numbers: suppose you sell an item for $30.00 with free shipping, and the buyer pays $2.40 in sales tax, so the total is $32.40. Assume a hypothetical 13% final value fee and a 3% ad rate, and a buyer in the US.

1. Final value fee at 13% of $32.40: $4.21.
2. Per-order fee (order over $10): $0.40.
3. Ad fee at 3% of $32.40: $0.97.
4. Item cost and shipping: $18.00.
5. Problem order allowance: $0.60.

You receive the $30.00, not the sales tax, so profit is $30.00 minus $24.18 = $5.82, before income tax. Notice that the fees were charged on $32.40: the sales tax raises your fees even though you never keep it.

How do you turn profit into a margin you can compare?

Divide profit by the item price (the money you keep, before tax) and multiply by 100. In the UK example, £4.76 divided by £25.00 is a margin of about 19%. In the US example, $5.82 divided by $30.00 is about 19.4%.

Margin is not the same as markup, which divides profit by cost. Mixing the two up is one of the most common pricing mistakes; our guide to markup vs margin shows the conversion. Margin is the better figure for comparing products at different prices.

What mistakes make an eBay profit figure wrong?

• Working out the final value fee on the item price only, when it is charged on the total including postage and taxes.
• Forgetting the per-order fee, which is large in proportion on cheap items.
• Leaving out the ad fee because it is shown separately on your statement.
• Ignoring refunds and returns because they happen on other orders.
• Counting VAT or sales tax as income.
• Using last month's fee rates after eBay has changed them.

What to do next

1. Pick your best-selling listing and run the five steps on its last sale.
2. Check the real fee rate for its category on eBay's fee page, not a remembered figure.
3. Pull your refunds and returns for the last few months and work out your problem order allowance.
4. Put the steps in a spreadsheet so you can run any listing in a minute.
5. Compare the result with eBay's own figures in Seller Hub for a few orders, and fix any step that does not match.
