eBay Price Rounding Rules: How to Round Automated Prices Without Losing Margin
In short
There is no single official set of eBay price rounding rules, so the rules are yours to set. The safe approach: work out the price that covers cost, fees and profit, then round up, never to the nearest figure, and check your minimum profit still holds after rounding. Use the same rule on every listing.
Key takeaways
- eBay does not require any particular price ending in the policies we read, so rounding rules are your own to set.
- Round last and round up: rounding to the nearest figure gives profit away on about half your listings.
- On cheap items a few pence lost to rounding can be a large share of the profit, so use finer steps there.
- Check your minimum profit floor against the rounded price, not the calculated one.
- Convert currency and add fees first, then round in the listing currency.
What are the eBay price rounding rules?
There is no official list of eBay price rounding rules. In the eBay policy pages we read for this article, nothing requires a price to end in .99 or any other figure, so the rules that matter are the ones you set for your own automated prices. This guide gives you a rule set that protects margin on eBay.co.uk and eBay.com.
Rounding means moving a calculated price, such as £27.06, to a tidier figure such as £27.99. When a repricer or a spreadsheet sets hundreds of prices, that small move happens on every listing and on every sale. The direction of the rounding matters more than the ending you pick.
Three rules cover most of the risk:
- Round last. Work out cost, profit and fees first, and round only the final price.
- Round up, not to the nearest figure. A price that moves down gives away profit you planned to keep.
- Check your profit floor after rounding. The rounded price, not the calculated one, is what the buyer pays.
Should you round eBay prices up, down or to the nearest figure?
Round up. Rounding to the nearest figure sounds fair, but some listings gain and some lose, and you cannot see in advance which. A loss lands as hard on a listing with a thin margin as a gain helps one with a thick margin.
| Method | What it does | Effect on margin | Best used when |
|---|---|---|---|
| Round up to the next ending | Moves £27.06 to £27.99 | Keeps or adds profit, and the buyer pays a little more | Margin is tight, or you automate prices and cannot check each one |
| Round to the nearest ending | Moves £27.06 to £26.99 | Some prices rise, some fall | You have room in the margin and a profit floor as a safety net |
| Round down | Moves £27.06 to £26.99 every time | Always gives profit away | Rarely. Only for a deliberate promotion above your floor |
| No rounding | Keeps £27.06 exactly | Profit is exactly as planned | You do not care about a tidy-looking price |
If your tool offers a .99 ending, check whether it rounds up, down or to the nearest figure before you turn it on. The setting name often does not tell you.
How much margin does rounding cost? A worked example
Rounding costs more than it looks, because eBay fees are mostly a percentage of the sale price, and the price you round is the same figure those fees are taken from. Use the examples below to see the effect.
Example (hypothetical numbers): suppose an item costs £20.00 on Amazon and you want £3.00 profit. Suppose your combined percentage fees come to 15% of the sale price. That 15% is a hypothetical rate for the arithmetic, not eBay's actual rate: fees vary by category and account, so check the eBay UK selling fees page or the fee page for your marketplace. If your fees include a fixed amount per order, add it to the top line of the sum.
The price that covers cost, profit and fees is (20.00 + 3.00) divided by (1 minus 0.15), which is £27.06 once rounded to the penny. Here is what each rounding choice does to your profit.
| Price you list | Fees at 15% | Profit after £20.00 cost | Against the £3.00 target |
|---|---|---|---|
| £27.06 (exact) | £4.06 | £3.00 | On target |
| £26.99 (nearest .99) | £4.05 | £2.94 | 6p short |
| £27.99 (rounded up to .99) | £4.20 | £3.79 | 79p above |
Six pence looks harmless on one sale. Across thousands of sales it adds up, and it matters more when the profit per sale is small.
Cheap items feel rounding most
Example (hypothetical numbers): suppose an item costs £3.77 and you want £1.50 profit, again with a hypothetical 15% fee rate. The calculated price is £6.20. Now compare the endings you could choose.
| Price you list | Fees at 15% | Profit after £3.77 cost | Change in profit |
|---|---|---|---|
| £6.20 (exact) | £0.93 | £1.50 | None |
| £5.99 (nearest .99) | £0.90 | £1.32 | 18p lost, 12% of your profit |
| £6.49 (up to .49) | £0.97 | £1.75 | 25p gained |
| £6.99 (up to .99) | £1.05 | £2.17 | 67p gained, but a 79p higher price |
The same 18p that is barely visible on a £27 item takes 12% of the profit here. This is why a profit floor matters most on cheap listings: see how to set a minimum profit per sale.
Notice the last row too. With only .99 endings, your choices are £5.99 or £6.99, a £1 gap. That is a big step on a £6 item. Finer steps solve this.
Which price endings should you use: .99.49 or whole numbers?
Use whichever ending suits your buyers, as long as the step between endings is small relative to the price. The smaller the item, the finer your steps should be. There is no ending that eBay requires or rewards in its published guidance.
- .99 only: steps of £1 or $1. Fine for items priced in the tens, coarse for items under about £10 or $10.
- .49 and .99: steps of 50p or 50 cents. A reasonable middle ground for cheap items.
- .95 and .99 or other fine steps: steps of a few pence or cents. These move the price least, so they protect margin and competitiveness best.
- Whole numbers: clean, but the same step size problem as .99.
Example rule (a suggestion, not an eBay rule): under £10, round up to the next .49 or .99; from £10 upwards, round up to the next .99. Use dollars with the same bands on eBay.com if you like.
Does a rounded price change your search ranking?
eBay says price is one of the Best Match factors, along with how closely a listing matches the search, how popular the item is, listing quality, completeness, listing terms and the seller's track record. eBay does not say how much weight each carries, and it does not say anything about price endings. You can read the list on the eBay Best Match page.
So treat endings as a buyer-facing choice, not a ranking trick. If you want to find out what works for your category, test it fairly. Our guide to psychological pricing on eBay covers which tactics are worth testing and which to skip.
How do you round prices across currencies and variations?
Round in the currency the listing is sold in, and do it after every conversion and fee step. A UK seller on eBay.co.uk lists in pounds and pence. A US seller on eBay.com lists in dollars and cents. The principle is the same, so the rest of this section applies to both.
Cross-currency listings
If your cost is in one currency and the listing is in another, convert first, add your profit, gross up the fees, and only then round. If you round the converted cost first, the error is carried through every later step.
Remember that eBay's seller currency conversion charge is 2.5%, rising to 2.75% from 1 December 2026, according to the eBay UK selling fees page. Include it in the percentage you gross up, so that rounding does not have to cover it. A price in the wrong currency should never go live: a currency guard that stops a push when the currencies do not match is a sensible safeguard.
Multi-variation listings
On a listing with several options, such as sizes or colours, each variation has its own cost. Round each variation from its own calculated price. If you force every variation to the same price to keep things tidy, the dearest variation loses margin and the cheapest gives profit away. Apply your profit floor to each one separately.
How do you set a rounding rule in automated pricing?
Write the rule down once, in the order the sums happen, and then apply it to every listing. These steps work in a spreadsheet, in Seller Hub bulk edits or in a repricer.
- List the steps in order. Cost, then markup or profit, then fees grossed up, then rounding. Rounding is always last.
- Pick the direction. Choose up unless you have a reason to do otherwise.
- Pick the step by price band. Finer steps for cheap items, coarser steps for dearer ones.
- Set a profit floor and test it on the rounded price. A floor that is checked before rounding can still be broken by rounding down.
- Set limits. A ceiling and a swing limit stop a bad cost reading being rounded into a live price. See the eBay pricing formula for how the pieces fit.
- Check ten listings by hand. Pick a mix of cheap and dear items and confirm the profit on each matches your sums.
Dropizon's pricing formula has a markup (percentage or fixed), eBay fees grossed up into the price, a minimum profit floor, optional .99 endings and per-listing overrides, and it records a reason for every price push and every hold. The Dropizon documentation describes each setting. As with any tool, test a few listings before you apply a setting to all of them.
A note on sourcing from Amazon
Everything above applies whatever your supplier is, but many readers of this guide source from Amazon, so the rule is worth stating. eBay says that dropshipping, where you fulfil orders directly from a wholesale supplier, is allowed. Listing an item on eBay and then buying it from another retailer or marketplace that ships directly to your customer is not allowed. Even when dropshipping, you are responsible for safe delivery within the time stated in the listing and for the buyer's overall satisfaction. Read the policy on eBay.co.uk or eBay.com before you decide how to source.
A quick checklist before you apply a rounding rule
- Fees are grossed up into the price before anything is rounded.
- The rule rounds up, or you have chosen a different direction on purpose.
- Cheap items use finer steps than dear ones.
- The minimum profit floor is tested against the rounded price.
- Each variation is rounded from its own calculated price.
- Currency conversion happens before rounding, and the final price is rounded in the listing currency.
- Ten listings have been checked by hand.
- You will recheck your fee rate when eBay changes its fees, because rounding sits on top of a fee percentage that can move.
Frequently asked questions
Do I have to end eBay prices in .99?
No. The eBay pages we read for this article do not require .99 or any other ending. It is a buyer-facing choice, so pick the ending that fits your item and test it. Make sure the step between endings is small enough that you do not lose margin.
Should I round before or after adding eBay fees?
After. Work out cost, profit and fees first, then round the final price. If you round earlier, the error carries through every later step and can leave you short of your target profit.
Does rounding a price change the fees I pay?
Yes, because most eBay fees are a percentage of the sale amount. A higher rounded price means slightly higher fees, and a lower price means slightly lower fees. Promoted Listings general campaigns, for example, charge the ad rate as a percentage of the total sale amount, including postage and taxes.
What if rounding up makes my price uncompetitive?
Use finer steps, such as .49 or .95 endings, so the price moves less. If you still need a lower price, accept a smaller profit but keep it above your floor. Avoid rounding down by habit, because that gives profit away on every listing.
How do I round prices when my cost is in a different currency?
Convert the cost first, add your profit, gross up eBay fees including any currency conversion charge, and then round in the listing currency. Rounding the converted cost early introduces errors that carry into the final price.
