inflation calculator

This inflation calculator will tell how much goods and services cost years ago in today’s money and vice versa.

The data uses general consumer price inflation data provided from the Reserve Bank of New Zealand. This is an average number across a wide range of goods and services. Do note that some goods and services go up or down in price at rates that are different to the average inflation rate. It is an indication of general price changes only.

I have used the annual inflation rate from the annual March data. The data runs from 1960 to the most current March.
