What a bid now is likely to become
Multiply the current bid + shipping by the factor for its time left. The middle half of auctions finished between the low and high factors. "Rose" is the share of auctions whose price went up at all after that point.
| Time left | Typical factor | Middle half | Rose | Looks |
|---|---|---|---|---|
| under 1 hour | ×1.00 | ×1.00–1.00 | 0% | 1 |
| 1–3 hours | ×1.00 | ×1.00–1.00 | 21% | 19 |
| 3–6 hours | ×1.00 | ×1.00–1.00 | 14% | 14 |
At the close, auctions finished at a median of 78% of the same product's typical Buy It Now price that day (middle half 67–88%, 17 auctions).

How this is measured
eBay's API shows live auctions only, not sold prices, so we record each auction's bid + shipping every time we see it (hourly for the products with the most auctions, twice a day for the rest). An auction's final price is the last bid we saw within an hour of its end; bids placed in the final minutes are missed, so real finals are often a little higher. Product pages use these factors to show a "likely final" price for each live auction, with the middle-half range. Listings for parts, lots and broken units are excluded, as on the rest of the site (how we price).
