Understanding Purchasing Power
Purchasing power refers to the value of money in terms of the goods and services it can buy. As prices rise due to inflation, the purchasing power of your money decreases.
About UK Inflation Measures
This calculator uses official inflation data from the Office for National Statistics (ONS):
- CPI (Consumer Price Index): The UK's main measure of inflation since 1996. It tracks the changing cost of a basket of goods and services, including food, transportation, and recreation, but excludes housing costs like mortgage interest payments. Our data goes back to 1914.
- RPI (Retail Price Index): An older measure that includes housing costs such as mortgage interest payments and council tax. RPI typically shows higher inflation rates than CPI. Data goes back to 1948.
