Using cso CPI website for source of - 0.3% for 2015 ......
[broken link removed]
"The % change in the CPI from Mar 2015 to Mar 2016 is -0.3%."
Looks like they announce in april based on march to march !
Looking at 2016 " so far "...
The % change in the CPI from Mar 2016 to Nov 2016 is 0.0%.
A basket of goods and services that cost €1,000 in Mar 2016 would have cost €1,000.00 in Nov 2016.
Calculations
Percentage change = ( (indexTo - indexFrom) / indexFrom ) * 100
(101.20 - 101.20 / 101.20) * 100 = 0.0%
