Dearness Allowance (DA) & Arrears
Dearness Allowance (DA) plays a key role in government salaries and pensions. This guide explains what DA is, how DA arrears are calculated, and how you can quickly estimate your arrear amount using a calculator.
What Is Dearness Allowance (DA)?
Dearness Allowance (DA) is a cost-of-living adjustment paid to Central Government employees, State Government employees, and pensioners. Its purpose is simple: to protect your salary from inflation.
As prices rise, DA increases so your purchasing power stays intact.
Example:
If your Basic Pay is ₹50,000 and DA is 50%, your DA equals ₹25,000 per month.
How Often Is DA Revised?
DA is revised twice a year:
- 1 January
- 1 July
The revision is based on the Consumer Price Index (CPI), which measures inflation. Although the new rate applies from the effective date, the official notification is usually issued later—this delay leads to DA arrears.
What Are DA Arrears?
DA arrears are the back-payments you receive for the period between:
- The effective date of the DA hike, and
- The date the government issues the notification
Example:
If DA is effective from January 1 but announced in November, you receive arrears for January to November.
DA Arrear Calculation Formula
DA Arrear = (New DA% − Old DA%) × Basic Pay × Months ÷ 100
Where:
- Basic Pay = Salary excluding allowances
- Months = From effective date to notification date
Practical Examples
Example 1: Central Government Employee
- Basic Pay: ₹75,000
- DA increases from 46% to 50%
- Effective: January | Notified: March
Arrear = (4% × 75,000 × 3) ÷ 100 = ₹9,000
Example 2: Pensioner
- Pension (Basic equivalent): ₹60,000
- DA increases from 48% to 50%
- Effective: July | Notified: September
Arrear = (2% × 60,000 × 3) ÷ 100 = ₹3,600
Example 3: Leave or Suspension
DA arrears are still calculated on Basic Pay, even if you were on leave during the arrear period.
How DA Impacts Other Salary Components
A DA hike affects more than just take-home pay:
- HRA: Recalculated when DA crosses thresholds (e.g., 50%)
- Travel Allowance: Some components are DA-linked
- NPS: Contributions increase as they are based on (Basic + DA)
- Income Tax: DA arrears are taxable in the year received
Special Situations
- Promotion during arrear period: Arrears are calculated on old and new Basic Pay for respective months
- Joined mid-year: Arrears apply only from your joining date
- Leave Without Pay (LWP): Generally paid on the Basic Pay of the post held
- State Government employees: DA rules are similar but may vary by state
Latest DA Status & 8th Pay Commission
- As of January 2026, DA under the 7th Pay Commission is 50%
- At 50% DA:
- HRA resets
- Other allowances may be revised
- The 8th Pay Commission (expected 2026–27) may:
- Increase Basic Pay by 80–100% (fitment factor)
- Reset DA to near 0%, which will rise again over time
Conclusion
DA protects your salary from inflation, and DA arrears ensure you don’t lose money due to delayed announcements. Understanding both helps you plan your income better and avoid surprises.
