Methodology and data limitations

English reference page. This article is not translated. The interactive interface retains your selected language for navigation.

Result = source amount × source USD price ÷ target USD reference price. The target unit may be an item, area, weight, or service period.

Crypto prices are requested from CoinGecko and refreshed periodically. Currency uses USD-based rates from Frankfurter, with exchangerate.host and open.er-api fallbacks. Non-USD amounts are divided by their currency-per-USD rate. Provider availability and freshness are not guaranteed.

Stock and target prices are bundled illustrative estimates, not live quotes or verified current offers.

Missing source data remains unavailable. JavaScript is required for data requests and interactive calculations. Static pages explain the method without live values.

Comparisons exclude taxes, fees, slippage, delivery, regional differences and changes in specifications. They are not a formal cost-of-living index or investment advice.
