1. What is CPI Rent Increase?

The Consumer Price Index (CPI) rent increase is a method used in the UK to adjust rental prices in line with inflation. It's commonly used for social housing and some private rentals following government guidelines.

2. How Does the Calculator Work?

The calculator uses the standard CPI rent increase formula:

Where:

• \( CPI \) — Consumer Price Index percentage (inflation rate)
• \( Current Rent \) — The existing monthly rental amount

Explanation: The calculation shows how much your rent will increase based on the current inflation rate.
