1. What is RPI Rent Increase?

The RPI (Retail Price Index) Rent Increase is a method used in the UK to adjust rental prices based on inflation. It calculates the new rent by applying the percentage change in the Retail Price Index to the current rent.

2. How Does the Calculator Work?

The calculator uses the RPI Rent Increase formula:

Where:

• \( \text{Current Rent} \) — The existing rental amount in GBP
• \( \text{RPI Rate} \) — The percentage increase based on Retail Price Index

Explanation: The formula applies the RPI percentage increase to the current rent to calculate the adjusted rental amount.

3. Importance of RPI Rent Calculation

Details: RPI-based rent increases are commonly used in commercial leases and some residential tenancies in the UK. They provide a transparent method for annual rent adjustments tied to inflation.

4. Using the Calculator

Tips: Enter the current rent amount in GBP and the RPI rate as a percentage. Both values must be positive numbers.
