### Purchasing Power of British Pounds from 1264 to 2007

The measure used in this calculator is the longest series of its
kind. See a discussion of
Using the Retail Price Index (RPI). Other comparison series
might be preferable, depending on the context of the question. For
more choices consult
Five Ways to Compute the Relative Value of a UK
Pound Amount, 1830 - 2006, where you will find further discussion of
this issue.

To determine the value of an amount of money in a particular
("original") year compared to another ("desired") year, enter the
values in the appropriate places below. For example, you may want to
know: How much money would you need in the year *2005*, to have the
same "purchasing power" of *£500* in year *1975*. If you entered these
values in the correct places, you will find that the answer is *£2,808.67*.

Prior to February 15, 1971 ("Decimal day," or "D-day"), monetary
amounts in the U.K. were expressed as pounds (£),
shillings (s.) and pence (d.), where £1 = 20s. = 240d. After 1970,
there were 100 pennies in a pound, so one (new) penny = 2.4 old pence.
All numbers should be entered in decimal rather than fractional
form (for example, 1.5 rather than 1 1/2).
