1. What is CPI Rent Increase?

In New Zealand, rent increases are often tied to the Consumer Price Index (CPI), which measures inflation. This calculator helps determine how much rent can increase based on the current CPI percentage and existing rent amount.

2. How the Calculator Works

The calculator uses the simple formula:

Where:

• Current Rent — The existing monthly rent amount in NZD
• CPI — The annual inflation rate percentage

Example: If current rent is $500/week and CPI is 3%, the increase would be $500 × 0.03 = $15/week.

3. Importance for NZ Tenants and Landlords

Details: Understanding rent increases helps tenants budget effectively and ensures landlords comply with NZ tenancy laws regarding reasonable rent adjustments.

4. Using the Calculator

Tips: Enter the current CPI percentage (available from Stats NZ) and your current rent amount. The calculator will show both the increase amount and new total rent.
