How to measure inflation
CPI (consumer price index)
RPI (retail price index)
CPI (consumer price index)
- measure of inflation. ONS(office of national statistics) sends its researchers around the country each month to gather the prices of a ‘basket’ of goods and services to represent a typical family. The goods are weighted and this shows the proportion of income people spend on these goods
- basket including 700 goods
- 7000 households
- doesn’t include housing costs
Hyperinflation
Extremely rapid or out of control inflation
Can cause the currency to change
Zimbabwe’s inflation rate
11.2m%
Uk inflation rate
January CPI= 0.3%
rpi=1.1%
Deflation
Is the decrease in normal prices for goods and services and increase in the value of money
Shoe leather

How to measure inflation (calculation)
The change/base year X100
How Is the price index is measured
- living cost and food survey collects information from 7000 households in the UK
- weights assigned to each good
- weights show what proportion of income is spent on goods that are bought by the average household
- price survey is undertaken once a month about the changes in the price level of 700 goods and services used
- price changes are multiplied by the weights to give a price index
Disadvantages of cpi
- may not be a representative figure of the changes in living costs as it does not include housing costs
- people’s spending patterns may not be representative
How to calculate an index number
Base year x (new price-old price) / old price
