1. What is CPI Rent Increase?

A CPI (Consumer Price Index) rent increase adjusts rental prices based on inflation rates to maintain the property's value in real terms. It's commonly used in lease agreements to provide fair, market-based rent adjustments.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

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

Explanation: The calculation determines how much the rent should increase to keep pace with inflation, maintaining the landlord's purchasing power while being fair to tenants.

3. Importance of CPI Rent Adjustment

Details: CPI-based rent increases help maintain property value over time, prevent sudden large rent hikes, and provide predictable, gradual adjustments tied to economic conditions.

4. Using the Calculator

Tips: Enter current monthly rent amount and the CPI percentage (annual inflation rate). The calculator will show both the increase amount and new total rent.
