Retail Price Index (RPI) Definition.

The Retail Price Index (RPI) is a measure of inflation in the United Kingdom. It is calculated by the Office for National Statistics (ONS) and is based on a basket of goods and services that represent typical household spending. The RPI is used to adjust a wide range of financial contracts and benefits, such as pensions and rents, and is also used as a measure of inflation in economic analysis.

The RPI is calculated using a weighted average of prices for a selection of around 700 representative goods and services. The weights are based on the average spending patterns of households in the United Kingdom. The basket of goods and services is updated each year to reflect changes in spending patterns.

The RPI is published monthly, and is typically expressed as a percentage change from the previous month or the previous year. The RPI is calculated using a formula that takes into account the prices of the goods and services in the basket, the weights of the different items in the basket, and the effect of changes in tax rates.

The RPI is the most widely used measure of inflation in the United Kingdom, but it is not the only measure. The Consumer Price Index (CPI) is another measure of inflation that is calculated by the ONS. The CPI is a more comprehensive measure of inflation than the RPI, as it includes a wider range of goods and services and is designed to be more representative of household spending.

The ONS publishes the RPI every month.

How is retail price index calculated?

The retail price index (RPI) is a measure of inflation used in the United Kingdom. It is calculated using a basket of goods and services that represents the typical purchases of a "basket" of households. The basket is updated every year to ensure that it remains representative of typical household spending patterns.

The RPI is calculated using the following formula:

RPI = (ΣP1Q1 + ΣP2Q2 + ... + ΣPnQn) / (ΣQ1 + ΣQ2 + ... + ΣQn)

Where:

P1, P2, ..., Pn are the prices of the goods and services in the basket

Q1, Q2, ..., Qn are the quantities of the goods and services in the basket

Σ represents the summation operator
