1. What is Commercial Rent Increase Calculation?

Commercial rent increases in the UK are often tied to the Consumer Price Index (CPI) or Retail Price Index (RPI). This calculator helps landlords and tenants estimate the annual rent adjustment based on the current inflation rate and existing rent amount.

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

• Current Rent — The existing monthly rent amount in GBP
• CPI — The Consumer Price Index percentage (inflation rate)

Explanation: The calculation provides the monetary increase amount, which is then added to the current rent to determine the new rent amount.

3. Importance of Rent Increase Calculation

Details: Understanding potential rent increases helps both landlords and tenants with financial planning. For landlords, it ensures rental income keeps pace with inflation. For tenants, it helps anticipate business expenses.

4. Using the Calculator

Tips: Enter the current CPI percentage (available from the Office for National Statistics) and your current monthly rent amount. The calculator will show both the increase amount and the new total rent.
