DA Calculator: Complete Dearness Allowance Guide
For over 1 Crore Central Government employees, State Government staff, Defense personnel, and pensioners in India, Dearness Allowance (DA) and Dearness Relief (DR) are vital financial cushions against rising consumer inflation.
Dearness Allowance (DA) is a cost-of-living adjustment allowance revised semi-annually (effective 1st January and 1st July) by the Union Cabinet based on the 12-month average of the All India Consumer Price Index for Industrial Workers (AICPIN-IW). Under 7th Pay Commission rules, DA revisions directly increase monthly paychecks, trigger mandatory House Rent Allowance (HRA) slab upgrades (reaching 30% in Metro cities when DA hits 50%), and result in lump-sum DA Arrears. Our free online DA Calculator computes your exact monthly DA hike, revised gross salary, HRA upgrades, and pending DA arrears.

How 7th Pay Commission DA is Calculated (AICPIN Formula)
Dearness Allowance for Central Government employees under the 7th Pay Commission is calculated using the Labour Bureau's AICPIN-IW (Base Year 2016=100) 12-month average formula:
7th CPC DA % = [ (Average of AICPIN-IW for last 12 months - 261.41) / 261.41 ] * 100
