Dearness Allowance (DA) arrears are one of the most important components of salary revisions for central government employees. When the government announces a DA hike with retrospective effect, employees become eligible for arrears covering the period from the effective date to the announcement date. This comprehensive guide explains everything about DA arrears calculation in 2026.
What is Dearness Allowance (DA)?
Dearness Allowance is a cost of living adjustment allowance paid to government employees and pensioners. It is calculated as a percentage of basic pay and is revised twice a year (January and July) based on the All India Consumer Price Index (AICPI).

Understanding DA Arrears
DA arrears occur when:
- The government announces a DA hike
- The hike is effective from a past date (retrospective implementation)
- Employees need to be compensated for the difference between old and new DA rates
For example, if DA increases from 50% to 53% effective January 1, 2026, but the order is issued in March 2026, employees are entitled to 3 months of arrears (January to March).DA Arrears Calculator 2026 Formula
The formula for calculating DA arrears is straightforward:
DA Arrears = (New DA% – Old DA%) × Basic Pay × Number of Months
Step-by-Step Calculation Example
Let’s calculate DA arrears with a practical example:
Given:
- Basic Pay: ₹50,000
- Old DA Rate: 50%
- New DA Rate: 53%
- Arrears Period: 3 months (January to March 2026)
Calculation:
- DA Difference = 53% – 50% = 3%
- Monthly Arrears = 3% × ₹50,000 = ₹1,500
- Total Arrears = ₹1,500 × 3 months = ₹4,500
