How Listaza Prices Your Items

Pricing suggestions in Listaza come from real, comparable active listings on eBay — not AI guesses.

The source: real, active eBay listings

When you generate a listing, Listaza searches eBay's current fixed-price listings for items similar to yours — restricted to US listings priced in USD, and filtered to exclude multi-item lots. These are what sellers are asking for comparable items right now, which makes them a useful signal for how to price yours.

Listaza requests up to 15 comparable listings per search. The results are cached so repeat searches for the same item type are fast.

Low, average, and high — not a single number

Rather than surfacing a single suggested price, Listaza shows a range:

  • Low — the 20th percentile of comparable asking prices. A competitive price for a quick listing.
  • Average — a trimmed mean that excludes the top and bottom 10% of results to reduce the influence of outliers.
  • High — the 80th percentile. Reflects listings priced for exceptional condition or presentation.

A confidence score accompanies the range. It is based on how many comparable listings were found and how consistent the prices were. More comps with tighter price variance means a higher confidence score.

An example

A search for Nike TNs, Size UK 8.5, Like New returned 15 comparable active listings with prices ranging from $770 to $999. From those results, Listaza calculates the low, average, and high values and attaches a confidence score reflecting how closely the comps matched the item condition and size.

Which marketplaces this applies to

The pricing range is sourced from active eBay listing data and is shown for all supported platforms — eBay, Facebook Marketplace, Etsy, Poshmark, and Mercari. Listaza surfaces the range so you can decide where to price based on your platform, your timeline, and how your listing compares to the comps.

This is an estimate, not an appraisal

Pricing suggestions in Listaza are a starting point, not a guaranteed sale price. Final prices depend on factors the algorithm cannot fully account for: the exact condition of your item, the quality of your photos, how your listing is written, timing, and buyer demand at the moment you list.

Use the range as a reference. Price toward the low end to sell faster; price toward the high end if your item is in exceptional condition and you can wait.
