1. What is CPI Rent Increase?

The Consumer Price Index (CPI) rent increase is a method used in New Zealand to calculate allowable rent increases based on inflation. It ensures rent adjustments are fair and tied to economic conditions.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

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

Explanation: The calculation shows how much your rent will increase based on the current inflation rate in New Zealand.
