CPI vs CPIH vs RPI Inflation
This chart compares the three main UK annual inflation measures — CPI, CPIH and RPI — using official ONS data.
This chart compares the three main UK annual inflation measures — CPI, CPIH and RPI — using official ONS data.
This chart shows the annual rate of inflation measured three ways: CPI (the Bank of England's target measure), CPIH (which adds owner-occupier housing costs) and RPI (an older legacy measure). All three are annual percentage changes, so they are compared directly.
This chart shows how the headline inflation measures differ, but it does not prove which measure is 'correct' for any purpose. RPI is not an Accredited Official Statistic and should be treated with caution.
