As per above data, we got 35% dearness allowance for last time based on % of increase in AICPIN.
If the index value remains 172 in June 2010, then % of increase value is 44.91,
=June 10 % of Increase index value minus Jan 10 % of Increase index value
=44.91 (-) 35.7
=9.21
| How to calculate % of increase ? Here is the simple formula for calculate increase percentage for AICPIN => DA = (Average of AICPIN for the past 12 months – 115.76)*100/115.76 |
If the index remains 172 in June 10, there will be an increase of 9%
Last dearness allowance is 35% + 9% during this year.
So there is a chances to get 44% Dearness allowance from 1st July 2010 onwards
