How this is calculated
- Value in the later year = amount × (consumer price index in the later year ÷ index in the earlier year). Uses OECD annual average consumer price indexes.
- This shows changes in the general price level only. Prices of individual items (housing, food, wages) moved differently, and it is not an exchange-rate conversion.
- The latest year for UK is 2025. For the U.S. and Japan, years after the latest OECD annual average are extended with the national consumer price index (BLS, Statistics Bureau of Japan).
