How to use the RPI and Rent Calculator.
The pre-set display is for example only. As soon as you click in a field, the preset will disappear.
To calculate the Retail Price Index (RPI) percentage change, enter the RPI figures for the start and end months. The percentage change for that period will be displayed. It's not necessary to enter either the start month/year or end month/year: that information is for your convenience.
To find out how much the rent should be to at least keep pace with the Retail Price Index (RPI), enter the rent per annum that you are receiving/paying at present. The adjusted rent will be displayed. (The rent per month or any other period of time will work as well.)
In the 'rent per annum' field, the figure may be entered with or without a £ sign or any commas, but the rent must be rounded to a whole number with no decimal point.
The 'rent per annum' field doesn't only have to be for rent, it may also be used for any figures such as price or cost of product or service where you want to calculate the RPI-adjusted equivalent.
The calculator is for information only: no details will be stored.

Retail Price Index and Rent Calculator
The Retail Prices Index or Retail Price Index - RPI - is a measure of inflation published monthly by the Office for National Statistics. It measures the change in the cost of a representative sample of retail goods and services. RPI was first calculated for June 1947 and was once the principal official measure of inflation. It has been superseded by the Consumer Price Index (CPI). Even so, RPI continues to be used in leases where rent reviews are index-linked, because the Retail Price Index is generally considered more favourable to landlords.
The RPI is normally published on or about 17th day of each month for the previous month.
Clicking a year will reveal the index figures monthly for that particular year.
[Please note: In 1987, the index was rebased to 100.0. To compare the index for any month from January 1974 until December 1986 with the figures from January 1987, multiply the index figure by 3.945]

RPI and Rent Calculator
To calculate the Retail Price Index (RPI) percentage change, enter the index figures for the start and end months. To check the rent to at least keep pace with the RPI, enter the rent payable* per annum - please round the figure to the nearest whole number, no decimal points. The adjusted rent will display. Although designed for yearly rent, the rent per month or any other period of time will work as well. This calculator is for information only: no details will be stored.
