Where the data comes from
Bayed works from eBay listings. When you run a search, it requests current data from eBay and combines it with sold listings it has already recorded.
Everything in a report describes eBay. It does not measure prices in shops, on other marketplaces, or across the wider market. Bayed is an independent service and is not affiliated with, endorsed by, or sponsored by eBay Inc.
What a sold listing is
A sold listing is a listing that eBay reports as sold. The record carries the title, the condition the seller chose, the listing format, the date, and a price.
- It does not show what happened next. A sale that was later cancelled, left unpaid, or returned can still appear as sold.
- Condition is the seller's label. Two listings marked Used can describe very different items, which is why a report lists the titles and not only the figures.
How the price figures are calculated
The price figures come from the sold listings that match your search and the filters you chose.
Median sold price
The middle price when the sales are sorted. Half sold for less and half for more. Start here, because one unusual sale barely moves it.
Average sold price
All the prices added up and divided by the number of sales. A few very high or very low sales pull it away from the typical price.
Lowest and highest
The two extremes in the period. They are often a bundle, a damaged item, or a mislabeled listing, so open the listing before you trust either one.
Middle of the range
Where most sales fell, such as the middle half of them. It describes how past sales were spread. It does not predict how quickly an item sells at a given price.
Best Offer sales
When a seller accepts a Best Offer, the public sold record keeps the listing price and does not show the amount that was agreed. Bayed works from those records, so it cannot see the accepted amount either.
Read the price on a Best Offer sale as the most the buyer could have paid. The real figure is lower. If many of the sales for an item were Best Offers, treat the sold-price figures as an upper bound.
eBay's own Product Research tool shows accepted offer amounts to sellers who have access to it. If the accepted amounts matter for your decision, check them there.
Matching the item and the condition
A report covers the listings that match your search. A loose search for a console can also match bundles, accessories, the tablet on its own, and special editions, and a figure calculated across all of them describes none of them.
- Search with a model number or a UPC when you have one.
- Look at one condition at a time. New, used, and for-parts sales are different markets.
- Read the titles in the list of sold listings and decide which ones match the item you are buying.
Sold counts, active counts, and the window
The sold count is the number of sold listings in the period the report covers. The active count is the number of listings for sale at the time of the search. One is a period and the other is a moment, so they are not measured the same way.
The count in a report is the number of listings its figures were calculated from. It can differ from the result count eBay shows for a similar search, because filters, timing, and the way results are grouped all affect that number.
Sell-through rate
Because the two counts are measured differently, the rate can pass 100%. A rate of 250% does not mean every listing sells. It means sales in the period were two and a half times the number of listings for sale now.
- What it tells you: how demand compares with current supply. It is useful for comparing one item with another.
- What it does not tell you: the chance that your own listing sells, how long it will take, or anything about price.
Some tools divide sold listings by sold and active listings together, which never passes 100%. Our sell-through rate calculator shows both.
Small samples
A median from 200 sales is steady. A median from six moves when one more sale is added. Check the count next to every figure, and remember that a condition filter lowers it. The count for the condition you chose is the one that matters.
Trends
Trend charts show how the number of sales and the sold price changed over the period. They describe what happened. A rising line is not a forecast, and a seasonal item can look weaker or stronger than it is depending on when you look.
What a report cannot tell you
- What your item will sell for. Past sales are a reference. Your result depends on the item itself, your listing, and your timing.
- What you will keep. Fees, shipping, repairs, and returns are your costs to add.
- Whether an item is genuine, working, or as described. A report reads listings. It does not inspect items.
- Prices on other channels. eBay sales are reference evidence. Apply your own expected selling price and costs for the place you sell.
Examples on this site
The sample report and the example on the homepage use made-up listings and are labeled as illustrative. They show how a report reads. They are not live eBay data and not a valuation.
