| net inflation rate |
The net increase (or decrease) in prices over a given period, expressed as a percentage of the prices at the start of the period.
Example:
The inflation index for January is published in accumulated format as 126,420. In June this figure rises to 194,520. Rounded off to two decimal places, this gives a net inflation rate of 53.87% (((194,520/126,420)-1)*100).
