Key term

What it means

CPI follows the prices of a changing selection of goods and services bought by households. A broad mix is used so that one price, such as petrol, does not stand for everyone's spending. The usual headline is the percentage change over the previous 12 months. CPI includes rent, but it does not include the costs of living in a home you own in the same way that CPIH does.

Example

If the CPI price measure goes from 200 to 210 in a year, it has risen by 5%. Your own shopping and bills may rise by a different amount.

Why it matters

CPI is widely quoted in news about inflation and is used for the Bank of England's inflation target. You need to know which price measure a headline uses before comparing figures.
