1. What is CPI Rent Increase?

The CPI (Consumer Price Index) rent increase is a method to adjust rental prices based on inflation. It's commonly used in rental agreements to provide fair, market-based rent adjustments tied to official inflation measures.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• CPI Percentage — Annual inflation rate (e.g., 3.5%)
• Current Rent — The existing monthly rental amount

Explanation: The calculation determines how much a rent should increase to maintain its real value against inflation.

3. Importance of CPI Rent Adjustment

Details: CPI-based adjustments help maintain fair rental prices for both landlords and tenants, protecting against inflation's erosion of value while preventing arbitrary rent increases.

4. Using the Calculator

Tips: Enter the current CPI percentage (without % sign) and current monthly rent amount. The calculator will show both the increase amount and new total rent.
