1. What is the NZ CPI Calculation?

The New Zealand Consumer Price Index (CPI) measures the rate of price change of goods and services purchased by households. This calculator computes a simple CPI ratio comparing current prices to base period prices.

2. How Does the Calculator Work?

The calculator uses the NZ CPI formula:

\[ CPI_{NZ} = \left( \frac{Current\_Price}{Base\_Price} \right) \times 100 \]

Where:

\( Current\_Price \) — Current price in NZD
\( Base\_Price \) — Base period price in NZD

Explanation: The formula calculates the price change relative to the base period, expressed as a percentage.
