Dearness Allowance (DA) Arrears: Formula, Announcement Cycles & History
- Routine 3-Month Arrears: DA is effective from Jan and July, but typically notified in March/April and Sept/Oct with 3 months of backpay.
- Standard Formula:
(New DA% − Old DA%) × Basic Pay × Months. - AICPI-IW Metric: DA hikes are strictly determined by 12-month average price indices published by the Labour Bureau.
Dearness Allowance is revised twice every year—effective 1 January and 1 July—based on the All India Consumer Price Index for Industrial Workers (AICPI-IW). Because DA hike orders are usually announced in March and October respectively, central employees regularly receive retrospective DA arrears.
1. The Regular 3-Month DA Arrear Cycle
- January DA Hike: Announced in March/April. Employees receive arrears for January, February, and March with their April salary.
- July DA Hike: Announced in September/October (typically before Diwali). Employees receive arrears for July, August, and September with their October salary.
2. DA Arrears Calculation Formula
Monthly DA Arrear = (New DA% − Old DA%) × Basic Pay
Total DA Arrear = Monthly DA Arrear × Number of Retroactive Months
3. Historical Precedent & 18-Month Withheld DA Status
During the pandemic, the Central Government froze three installments of DA and Dearness Relief (DR)—from 1 January 2020 to 30 June 2021. Staff side representations through the National Council (JCM) have consistently requested the release of these 18 months of withheld arrears. Our calculator allows modelling both standard retrospective DA cycles and extended duration scenarios.
