How we compare prices
What you paid, what the same components cost at a dated price check, and which parts enter the calculation.
See the illustrated example ↗Start with the exact component
Choose the model, capacity and version fitted in your PC. A different memory kit, storage capacity or graphics card variant is a different product, even when the names look similar.
Enter the amount you actually paid for each component. The purchase month and year are optional. RIGFLATION does not reconstruct old market prices from that date.
The tool covers CPU, graphics card, RAM, storage, motherboard, cooling, power supply and case. You can add several parts in a category, up to 24 parts per build.
Which sources supply the prices?
- United States · USD
- Amazon.com
- France · EUR
- Amazon.fr, PcComponentes, Rue du Commerce, Fnac, Darty, GrosBill, Cybertek, Topbiz
- Deutschland · EUR
- Amazon.de
- Italia · EUR
- Amazon.it
Automatic totals use offers explicitly identified as new and in stock, in the selected region’s currency. For a catalogue identity with several eligible merchant offers, the lowest eligible price is retained. Amazon supplies its own eligible offer. Amazon and catalogue references remain separate unless their identity has been verified.
In the reviewed GrosBill, Cybertek and Topbiz feeds, product condition is unspecified. Those offers can be shown for information, but do not enter automatic totals.
Delivery costs are excluded. The merchant’s checkout determines the final price, availability and any additional charges. Connected sources cover only part of the market.
Compare the same parts on both sides
If only six of eight components have a usable current price, both compared totals include those same six components. A missing offer is never treated as a zero-price component.
Total at check − total paid = difference
(Difference ÷ total paid) × 100 = change (%)
The percentage is shown only when the compared paid total is greater than zero.
A positive difference means buying those components would cost more at that check. A negative difference means it would cost less. Each physical component counts: two identical SSDs contribute two paid prices and two unit offer prices.
The result is a replacement-cost comparison for the same components. It does not estimate the resale value of a used PC, adjust for inflation, or measure performance per euro or dollar.
Read the date with the price
Every recorded price keeps its observation date. Merchant-feed offers older than 48 hours stop qualifying as current. A refresh or source failure does not make an old observation new.
If a source is unavailable, the tool can keep showing a previously saved price with its original date. Read that date before treating it as a current offer. A saved shared comparison keeps the prices captured when it was created; checking current offers is a separate action.
When you enter a price yourself
You can enter a price found elsewhere or your own estimate. It is labelled as entered by you, with its entry date, and takes precedence over an automatic offer until you edit or clear it. RIGFLATION does not verify that price with the merchant.
With neither an eligible offer nor a price entered by you, the component stays visible but remains outside both compared totals.
