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.

A quick look at 2015

What this means
If you earned, spent or received £500 in 2015, its purchasing power in today's money is about £732. In other words, to buy the same basket of goods and services in 2026 you'd need roughly £732 — a difference of £232 over 11 years.
The annualised inflation rate between 2015 and 2026 worked out at about 3.53% per year — compounded over that period that stacks up to the cumulative 46.4% change.
