1. What Is a Rent Increase Calculator California?

The Rent Increase Calculator California helps landlords and tenants determine the maximum allowable rent increase under California's AB 1482 Tenant Protection Act. It calculates based on the Consumer Price Index (CPI) plus 5%, capped at 10% maximum increase.

2. How Does the Calculator Work?

The calculator uses the AB 1482 formula:

Where:

• \( CPI \) — Consumer Price Index percentage change
• \( 5\% \) — Fixed percentage added to CPI
• \( 10\% \) — Maximum allowable increase cap
• \( Current Rent \) — The existing monthly rent amount

Explanation: The formula ensures rent increases are tied to inflation (CPI) but protects tenants with a 10% maximum cap.

3. Understanding California AB 1482

Details: AB 1482, effective January 1, 2020, establishes statewide rent control for eligible properties, limiting annual rent increases to 5% plus local CPI (or 10% maximum), whichever is lower.

4. Using the Calculator

Tips: Enter the current CPI percentage (available from Bureau of Labor Statistics) and current monthly rent. The calculator will show the maximum allowable increase and new rent amount.
