Inflation Calculator
The spreadsheet below can calculate inflation between your chosen dates
The Inflation Calculator can work out the RPIX and RPI changes between your chosen dates. It can also work out the change in a money value between those dates e.g. for a maintenance or rent review.
RPIX figures are available for any period between March 1999 and the most recent quarter. RPI figures are available for any period from March 1965 onwards. The calculator is updated with the latest figures when they are published each quarter.
