Table 7: Example computation of the percentage change
CPIH for current period (t),136.0
CPIH for previous period (t-1),129.9
First figure (t) less second figure (t-1) equals change,136.0 - 129.9 = 6.1
Divided by previous period CPIH (t-1) equals result,6.1/129.9 = 0.047
Multiplied by 100 equals the percentage change,0.047 x 100 = 4.7%
