Disclaimer

The data used in this currency converter comes from our historical records such as those of the royal household and Exchequer. These documents may record large purchases by government institutions rather than ordinary retail prices, and wages of skilled craftsmen rather than the general level of earnings. Our calculations are intended as a general guide to historical values, not a statement of fact.

You can find an inflation calculator from 1209 to 2017 at www.bankofengland.co.uk, and comparators (for the UK and various other countries) from 1270 to 2017 at measuringworth.com.

Calculations based on the retail price index may not always be appropriate: comparisons based on average earnings or gross domestic product per head may be more suitable. You can find comparators of both kinds at measuringworth.com, along with explanations of each type of calculation and of the sources on which they are based.
