1. What is RPI Rent Increase?

The RPI (Retail Price Index) rent increase is a method used in California (though less common than CPI) to calculate allowable rent increases based on inflation rates. It multiplies the current rent by the RPI percentage to determine the allowable increase.

2. How Does the Calculator Work?

The calculator uses the RPI rent increase formula:

Where:

• \( RPI \) — Retail Price Index inflation rate (as percentage)
• \( Current\ Rent \) — The current monthly rent amount in USD

Explanation: The equation calculates the dollar amount increase by applying the inflation rate percentage to the current rent amount.

3. Importance of Rent Increase Calculation

Details: Understanding rent increases helps both landlords and tenants plan finances, comply with local regulations, and maintain fair housing practices.

4. Using the Calculator

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