How this is calculated
We apply the ratio of the ONS Consumer Prices Index (CPI, series D7BT) between the two years — the same method used by the Bank of England's public inflation calculator. For example £100 in 2015 scales by 138.4 / 100.0 = 1.384 to give £138.40 in 2024.
The annualised rate is the compound inflation per year required to turn the start value into the end value over the period. The cumulative figure is the total change over the whole span.
