1. What is the Rental Increase Calculator?

The Rental Increase Calculator helps tenants and landlords in the UK calculate the monthly rent increase based on the annual Consumer Price Index (CPI) inflation rate. This method is commonly used for rent adjustments in line with inflation.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• CPI — Annual Consumer Price Index inflation rate (percentage)
• Current Rent — Monthly rental amount in GBP
• 12 — Converts annual increase to monthly amount

Explanation: The CPI percentage is applied to the annual rent amount, then divided by 12 to get the monthly increase.

3. Importance of CPI-based Rent Increases

Details: CPI-based rent increases provide a fair and transparent method for adjusting rents in line with inflation, protecting both landlords from rising costs and tenants from excessive increases.

4. Using the Calculator

Tips: Enter the current annual CPI percentage (available from the UK Office for National Statistics) and your current monthly rent in GBP. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)
