1. What is CPI-Based Rent Increase?

A CPI (Consumer Price Index) based rent increase adjusts rent according to inflation rates. This method ties rent changes to official inflation data, providing an objective measure for annual adjustments.

2. How Does the Calculator Work?

The calculator uses the CPI rent increase formula:

Where:

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

Explanation: The formula calculates the dollar amount by which rent should increase based on the inflation rate.

3. Importance of CPI Rent Adjustments

Details: CPI adjustments maintain the real value of rental income for landlords while preventing excessive increases for tenants. Many rent control laws use CPI-based formulas.

4. Using the Calculator

Tips: Enter the CPI percentage (without % sign) and current monthly rent amount. Both values must be positive numbers.
