How this is worked out
The two sums are plain arithmetic on the published index. Nothing is estimated or forecast.

Scripted comedy. Rich and M are AI characters and the £14 million never existed. Nothing here is advice.
Countries with no reliable data
The calculator only covers countries with at least 20 years of figures in this World Bank series. These are left out, and it is better to say so than to guess.
Too few years of figures: Bosnia and Herzegovina (19 years), Cayman Islands (8 years), Kiribati (19 years), Lebanon (18 years), Nauru (3 years), New Caledonia (7 years), Sint Maarten (Dutch part) (13 years), South Sudan (17 years), Tajikistan (17 years), Tuvalu (2 years), United Arab Emirates (19 years), Uzbekistan (16 years), Venezuela (9 years), Zimbabwe (14 years).
No figures in this series: American Samoa, Andorra, Argentina, Bermuda, British Virgin Islands, Channel Islands, Cuba, Eritrea, Faroe Islands, French Polynesia, Gibraltar, Greenland, Guam, Isle of Man, Liechtenstein, Marshall Islands, Monaco, North Korea, Northern Mariana Islands, Puerto Rico, Somalia, St. Martin (French part), Turkmenistan, Turks and Caicos Islands, Virgin Islands (U.S.).

How the calculator works
A consumer price index tracks the price of a typical basket of shopping in one country over time. The World Bank publishes one figure per country per year, with 2010 set to 100. To move an amount from one year to another, the calculator multiplies it by the index for the later year and divides by the index for the earlier year. To see what today's money would have bought back then, it does the same sum the other way round. It covers 178 countries that have at least 20 years of figures, from 1960 to 2025, and it always tells you the latest year it used, because some countries publish later than others.
An index is an average. Your own prices will have moved differently, and a national figure says nothing about any one shop, town or person.
