1. What is a California Rent Increase Calculator?

This calculator determines the maximum allowable rent increase under California's AB 1482 (Tenant Protection Act of 2019). The law caps annual rent increases at 5% plus the local CPI (Consumer Price Index), with a maximum cap of 10%.

2. How Does the Calculator Work?

The calculator uses the AB 1482 formula:

\[ \text{New Rent} = \text{Old Rent} \times \left(1 + \frac{\min(5 + \text{CPI}, 10)}{100}\right) \]

Where:

Old Rent — Current monthly rent amount
CPI — Percentage increase in Consumer Price Index for your area
5% — Base allowable increase under AB 1482
10% — Maximum total allowable increase

Explanation: The law allows landlords to increase rent by either 5% plus the local CPI percentage, or 10%, whichever is lower.
