1. What is CPI Rent Increase?

The CPI (Consumer Price Index) rent increase is a method used in New Zealand to calculate allowable rent increases based on inflation rates. It follows government guidelines to ensure fair and reasonable adjustments to rental prices.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( CPI \) — Consumer Price Index percentage (inflation rate)
• \( Current Rent \) — The current monthly rent amount in NZD

Explanation: The rent increase is calculated by multiplying the current rent by the CPI percentage (expressed as a decimal).

3. Importance of CPI Rent Calculations
