Frequently Asked Questions

We use the Consumer Price Index (CPI) from official national statistical offices. The formula is: Value Today = Historical Value * (CPI Today / CPI Historical).

Yes, for currencies like the Euro, the underlying data accounts for transitions from previous national currencies (e.g. Deutsche Mark) based on official fixed conversion rates and historical CPI link-series.

While we have full annual data for the Euro area, some other currencies use high-accuracy linear interpolation for years between major data points to ensure a smooth visualization of long-term trends.

Detailed Methodology & Calculation Logic

Purchasing Power Logic

The calculator determines the equivalent value of money across different years using Consumer Price Index (CPI) data.

  • CPI Ratio: Equivalent Value = Original Amount × (CPI in Target Year / CPI in Original Year).
  • Data Sources: We use official historical inflation data (e.g., ECB for EUR, Fed/BLS for USD) to provide accurate conversion rates.
Eras & Comparison

The tool contextualizes money by showing its value during significant historical economic eras.

  • Currency Support: Calculations are performed within the selected currency's specific historical index to account for regional inflation variations.
  • Temporal Trends: The visual projection highlights the 'decay' of purchasing power over time, illustrating the long-term impact of inflation on savings.
