1. What is the Rent Increase Percentage Calculator?

This calculator determines the maximum allowable rent increase percentage for residential properties in California under AB 1482 (Tenant Protection Act of 2019). It calculates the minimum of either CPI + 5% or 10%, whichever is lower.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( CPI \) — Consumer Price Index percentage (annual change)
• 5% — Fixed percentage added to CPI
• 10% — Maximum allowable rent increase cap

Explanation: The formula ensures rent increases don't exceed 10% annually, even if CPI + 5% would be higher.

3. Importance of Rent Increase Calculation

Details: Accurate rent increase calculation is crucial for landlords to comply with California law and for tenants to understand their rights under AB 1482.

4. Using the Calculator

Tips: Enter the current Consumer Price Index percentage (available from the Bureau of Labor Statistics). The calculator will determine the maximum allowable rent increase percentage.
