What is my PC worth?
We cannot give you a figure today, and this page explains exactly which half of the calculation is missing rather than showing you a number built from the other half.
Retail pricenot publishedWhy
This view does not use one current retailer offer. Exact Newegg matches appear on category pages while the approved Rakuten catalog is fresh. We keep one dated daily price for an exact product when the source permits it, but a short record is not turned into a trend, valuation, or buy-or-wait answer.
Every source we use, limit or refuse, each with the reason.
The answer today
Why there is no number here
Valuing a machine means valuing each part, and valuing a part means knowing what an an equivalent used one sells for right now. The approved Newegg catalog supplies some current new-item offers, not source-backed used-sale evidence for every part in a build.
When one part has no usable price, the answer for the whole machine is unknown. We do not add up the parts we could price and present that as the value, because a number built from four of six parts looks like the answer and is not. The calculator therefore stops until every listed part has a usable current price.
What you can do today
The curves below are real and published. If you look up what your parts currently sell for second hand, you can apply them yourself and get a defensible range rather than a guess. The formula is written out in full, deliberately.
The formula
What the calculation needs, and what we already hold
3 of the 5 inputs exist. The table says which ones do not, and no field on this page invites you to fill in the missing half.
| Input | What it has to carry | What we hold today |
|---|---|---|
| Today's price for the exact part | an amount, a currency, a public source, its address and the time it was read | we do not hold this |
| How recent that price is | it has to fall inside the freshness window the calculation declares | needs a price to test |
| How fast the part loses value | a low and a high multiplier, its stated basis, source and read time | we hold dated ranges current to 26 July 2026 |
| Which part it is, exactly | the manufacturer part number and configuration, so two similar parts are not merged | we hold this, across the six parts lists |
| How many of them | applied before the ranges are added together, never after | you supply this |
What the curves are based on. Each curve multiplies a permitted launch-relative baseline. The points are explicit model assumptions, not observations of used listings or current retail prices.
The formula. midpoint = launch-relative baseline x quantity x interpolated category multiplier x relative-performance adjustment; low and high apply the interpolated uncertainty.
Why it is a range and not a figure. A known contribution always has distinct low and high bounds. Missing launch-relative baselines remain unknown. Missing relative-performance positions widen the band without inventing a score.

The calculation in detail
Current source status, reviewed 2026-08-04: current Newegg offers now cover some exact catalog models, but the site has no source-backed used-sale evidence or complete six-part coverage for this calculator. It therefore cannot produce a resale range today and does not replace missing inputs with estimates. Sources considered and their current status.
What the range would mean
The result would be a resale-value range, not a minimum and not a single-point appraisal. For each part, the low end uses the lowest eligible current public price and the low end of its stated value-loss range. The high end uses the highest eligible current public price and the high end of that value-loss range. Quantity is applied before the part ranges are added.
Every value-loss range must name its basis, source URL, and retrieval timestamp. There is no hidden fallback rate. A part without a source-backed range remains unknown.
When the total is unknown
Every listed part needs a current public price inside the stated freshness window. If one part does not have one, the complete-machine total is unknown. Prices for the remaining parts are not added into a cheaper-looking partial total.
An unavailable result names the exact part and what is missing. A price outside its stated freshness window is unavailable rather than current, and the result records the newest checked timestamp and the applicable window.
What a part's price must include
Each current-price observation must identify the exact part, amount, currency, public source type, source URL, and retrieval timestamp. Each value-loss range must identify its low and high multipliers, stated basis, source URL, and retrieval timestamp. Future-dated observations, unsupported currencies, duplicate part identifiers, missing source checks, and a single multiplier presented as a range are not accepted.
The current Newegg feed is approved for current exact-model display and for this site's own forward-dated new-price observations. Neither one is evidence for used resale value, and not every catalog model has an exact current match. The sources page lists every source considered and the boundary applied to it.
Price data excluded
Amazon-derived price history and observations whose source does not explicitly permit this use are excluded. Sources considered and their current status, reviewed 2026-07-25.
What a result could not confirm
A computed range would follow the supplied current-price and value-loss evidence. It could not prove the condition of the physical machine, confirm that the entered model matches the installed part, or promise a completed sale at either end of the range. Those checks remain with the person inspecting and selling the PC.
