It is surprisingly easy to make regular eBay sales while earning little or no profit.
The money arriving in your bank can look healthy, but part of it belongs to eBay, your postage provider, your supplier and the taxman.
That is why I calculate the eBay break-even selling price before I publish a listing.
It tells me the lowest price I can accept without losing money once every relevant selling cost has been paid.
In this guide, I will show you the exact formula, a realistic UK worked example and the adjustments needed for Promoted Listings and VAT.
The article is aimed primarily at UK eBay business sellers because business and private seller fee structures are different.
Important: eBay changes its fees and category rates periodically.
The figures and links in this guide were checked on 30 July 2026, but you should always confirm your own rates in Seller Hub before setting a price.
What Is an eBay Break-Even Selling Price?
Your eBay break-even selling price is the amount a buyer must pay for your sale to produce exactly £0 profit and £0 loss. Sell below that price and you lose money.
Sell above it and the difference starts contributing towards profit.
Break-even is not the price you should normally charge. It is your financial floor.
I use it to judge whether a product is worth listing, decide the lowest
Best Offer I can accept and test whether a discount or promoted ad rate is affordable.
It is also useful when a competitor cuts their price and I need to decide whether matching them would be commercially sensible.
Sales revenue, eBay payouts and profit are three different numbers.
Your payout is what remains after certain eBay charges have been deducted, but it does not automatically account for the cost of your stock, postage, packaging, labour, returns or overheads.

Every Cost to Include Before You Calculate
The calculation is only reliable when every cost is included. Missing a few small expenses can turn an apparently profitable product into a loss over hundreds of orders.
Start with the direct cost of the item. Use the landed unit cost rather than only the supplier’s headline price.
That may include the wholesale price, inbound delivery, import duty, customs clearance and any preparation needed before sale.
Then include the costs created by fulfilling the order:
- postage or courier charge;
- box, envelope, tape, label and protective packaging;
- eBay final value fee and per-order fee;
- regulatory operating fee;
- Promoted Listings fee where applicable;
- listing upgrades or listing fees allocated to each sale;
- a sensible allowance for returns, losses and refunds;
- your per-order share of software, storage, Shop subscription and other overheads.
Your own time also has value.
If you want the business to pay you for picking, packing and customer service, include a labour allowance.
It is technically possible to calculate a cash break-even price without labour, but that can hide a business model that only works because you are working for free.
According to eBay’s current UK business seller fee page, the final value fee is a category-dependent percentage of the total sale amount plus a per-order charge.
The total sale amount includes the item price, postage and applicable taxes.
The eBay Break-Even Selling Price Formula
The mistake I often see is adding a percentage fee to the other costs. That does not work because the fee itself increases when the selling price increases.
You need to divide by the percentage of revenue you keep after variable fees.
Simple formula
Use this formula when all percentage fees are charged on the same total sale amount:
Break-even order total = (fixed costs + fixed eBay charges) ÷ (1 − combined percentage fee rate)
Then calculate the item price:
Break-even item price = break-even order total − postage charged to the buyer
In the formula:
- Fixed costs include stock, actual postage, packaging, labour, overhead and any fixed allowance.
- Fixed eBay charges include the per-order fee and any fixed selling cost.
- Combined percentage fee rate includes the final value fee, regulatory operating fee, expected Promoted Listings rate and any other sale-based percentage.
Convert percentages to decimals before using them. For example, 12.9% becomes 0.129.
Spreadsheet formula
If your fixed costs are in cell B2, fixed eBay charges in B3, combined percentage fees in B4 and buyer postage in B5, use:
=((B2+B3)/(1-B4))-B5
Enter the percentage in B4 as a real spreadsheet percentage, such as 18.25%. Do not enter 18.25 unless your formula divides it by 100.
This base formula assumes the percentage rate applies evenly to the entire order total.
Tiered category fees, international fees, VAT-registered sales and cost-per-click advertising can require a more detailed calculation.
A Worked UK eBay Break-Even Example
Let us calculate the minimum price for a UK business seller offering a small parcel with free delivery. This is an illustrative example rather than a universal eBay fee rate.
The per-order costs are:
- landed product cost: £8.00;
- Royal Mail or courier charge: £3.39;
- packaging: £0.35;
- labour and overhead allowance: £0.75;
- fixed eBay order fee: £0.40.
The fixed total is therefore £12.89.
For this example, assume a final value fee of 12.9%, the current regulatory operating fee of 0.35%, and a fixed Promoted Listings General rate of 5%. The combined variable rate is 18.25%, or 0.1825.
Now apply the formula:
£12.89 ÷ (1 − 0.1825) = £15.77
The calculated eBay break-even selling price is £15.77 before considering VAT on eBay fees.
Because eBay states that the business fees displayed on its UK fee page are exclusive of VAT, a non-VAT-registered seller who cannot reclaim that VAT must include it as a real cost.
If 20% VAT applies to all three percentage charges and the fixed order fee, the effective combined rate becomes 21.9% and the 40p charge becomes 48p. The revised calculation is:
(£12.49 + £0.48) ÷ (1 − 0.219) = £16.61
At £16.61, the example merely breaks even. I would not deliberately list at that price because there is no reward for risk, no buffer for a return and no profit to reinvest.
Rounding down can also create a small loss. If the calculation produces £16.61, pricing at £16.49 is below break-even. Round up and then add your intended profit.

How Advertising, Postage and VAT Change the Answer
Three areas cause most pricing errors: promoted advertising, postage charged to the buyer and VAT. Each can change the eBay break-even selling price significantly.
Promoted Listings
With Promoted Listings General, eBay says the ad fee is a percentage of the total sale amount when an eligible promoted sale is attributed.
That means the rate belongs in the percentage part of the formula.
If you promote at 8%, calculate a break-even price that assumes the 8% charge applies.
Do not treat an attributed ad fee as an occasional surprise.
Dynamic ad rates can move, so I would model a cautious rate based on the upper end I am prepared to pay.
Priority campaigns use cost-per-click charging, which does not fit the same per-sale percentage formula.
For those, divide total campaign spend by the number of resulting orders to estimate an advertising cost per order.
Postage paid by the buyer
Charging £3.99 postage does not mean you can simply subtract £3.99 from your delivery cost.
eBay normally calculates the final value and regulatory fees on the item price plus postage.
Calculate the required total order value first, then subtract the postage amount shown to the buyer.
If your break-even order total is £20 and you charge £3.99 postage, the break-even item price is £16.01.
Free postage and separately charged postage can produce the same order total, but they may affect buyer response and search visibility differently.
Test the presentation without losing sight of the total amount received.
VAT eBay break-even selling price
eBay’s published UK business fees are exclusive of VAT.
A seller who is not VAT registered normally treats the VAT added to those fees as a cost.
A VAT-registered seller generally needs a net-of-VAT profit calculation: remove output VAT from VAT-inclusive sales, use recoverable input VAT appropriately and work with net business costs.
VAT depends on the goods, seller and transaction, so do not rely on a generic shortcut when your business is registered.
HMRC’s VAT guidance for businesses is the appropriate starting point, and an accountant can confirm how the rules apply to your products.
eBay also reminds sellers that their responsibilities can include VAT on selling fees and VAT on sales in its taxes and import charges guidance.
From Break-Even Price to a Profitable Selling Price
Once I know the break-even figure, I add profit deliberately rather than choosing a price that merely looks competitive.
For a fixed cash profit target, use:
Required order total = (fixed costs + fixed eBay charges + target profit) ÷ (1 − combined percentage fee rate)
Using the VAT-inclusive example above, suppose I want to make £4 profit:
(£12.49 + £0.48 + £4.00) ÷ (1 − 0.219) = £21.73
The required selling price is therefore at least £21.73 with free postage. A sensible retail price might be £21.99 if the market supports it.
Margin and markup are not the same. Markup compares profit with product or total cost, while profit margin compares profit with revenue.
If you earn £4 on a £20 sale, your margin is 20%, not 25%.
I also add a small risk allowance where returns, damage, non-delivery or seasonal discounting are common.
A product that only makes money when every transaction goes perfectly is not priced safely.
Before listing, compare the required price with genuine sold listings rather than optimistic active listings.
If buyers consistently pay less than your profitable price, the answer may be to lower the product cost, improve the offer, reduce advertising, bundle products or walk away from that stock.

Common eBay Break-Even Pricing Mistakes
The first mistake is using the item price as the fee base when the fee is actually calculated on the item price plus postage and applicable taxes. That understates the charge.
The second is multiplying costs by a fee percentage. If your costs are £10 and the fee is 15%, adding £1.50 gives £11.50, but 15% of the eventual £11.50 selling price is £1.73. Dividing by 1 − fee rate solves this circular calculation.
Other common errors include:
- forgetting the fixed per-order fee;
- ignoring VAT added to eBay fees;
- leaving Promoted Listings out of attributed sales;
- using the supplier price instead of the landed unit cost;
- treating buyer-paid postage as fee-free income;
- forgetting packaging, labels, storage and labour;
- spreading monthly overhead across an unrealistic number of sales;
- accepting Best Offers without checking the minimum profitable price;
- confusing payout with profit;
- copying a competitor’s price without knowing their cost base.
Returns also need thought. You do not have to add the full value of a return to every order, but you can create an allowance from your records.
If return-related losses total £300 across 1,000 orders, adding 30p per order produces a more honest model.
Finally, review the calculation whenever your supplier, postage provider, eBay category, advertising rate or seller status changes.
eBay currently applies additional final value fee percentage points to certain Below Standard sellers and sellers with very high rates of “item not as described” requests, making old break-even figures unsafe.

FAQs eBay break-even selling price
Add every fixed cost and fixed fee, then divide that total by one minus your combined percentage fee rate. If you charge postage separately, calculate the required order total first and subtract the postage paid by the buyer.
For UK business sellers, eBay states that the total sale amount normally includes the item price, postage and applicable taxes. Check the current official fee page for exceptions that may apply to a particular category or programme.
Yes, when you reasonably expect the sale to attract an ad fee. Add a General campaign ad rate to the percentage fees. For cost-per-click advertising, estimate advertising cost per completed order from your campaign data.
Calculate two figures: an organic break-even price and a promoted break-even price. Your listed price should normally survive the promoted scenario if the listing remains enrolled in a campaign.
eBay states that the business fees on its UK fee page are exclusive of VAT. If you cannot recover the VAT, include the amount charged as a cost. VAT-registered sellers should calculate sales and recoverable business costs consistently on a net basis and take professional advice where needed.
Not quite. Break-even is the point where you make no profit. Your minimum offer should normally be above it by enough to provide your required profit and risk buffer.
Review every product when a major input changes, and check your core fee and postage assumptions at least monthly. Recalculate immediately after an eBay fee update, supplier increase, postage rise or advertising change.
Calculate Before You List
Your eBay break-even selling price gives you a firm financial boundary. It replaces guesswork with a number based on the real cost of buying, listing, advertising, packing and delivering an order.
The essential formula is:
(fixed costs + fixed charges) ÷ (1 − percentage fees)
Use that result as your floor, not your target. Add the profit you need, test the final price against sold-market evidence and leave enough room for the risks that come with running an online retail business.
Most importantly, keep the inputs current. A price that was profitable before a postage increase or ad-rate change may be losing money today.
