1. What is CPI Rent Increase?

The CPI (Consumer Price Index) rent increase is a method used to adjust rental prices based on inflation. For 2025, many jurisdictions cap the maximum allowable rent increase percentage, even if CPI is higher.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( CPI \) — Consumer Price Index percentage (inflation rate)
• \( Current\ Rent \) — Current monthly rental amount
• \( 2025\ Caps \) — Jurisdictional maximum increase limits (typically 5-10%)

Explanation: The calculation first determines the raw increase based on CPI, then applies any applicable 2025 caps to determine the final allowable increase.

3. Importance of Rent Increase Calculation

Details: Proper rent increase calculations ensure compliance with local rental laws, maintain landlord income with inflation, and provide fair, predictable increases for tenants.

4. Using the Calculator

Tips: Enter the current CPI percentage (without % sign) and current monthly rent amount. The calculator will show the raw CPI-based increase, the capped increase (if applicable), and the new rent amount.
