Dearness Allowance DA Calculator 2026

The Dearness Allowance (DA) for central government employees in 2026 is 55% of Basic Pay, effective from January 1, 2025. DA is revised twice a year — in January (effective from January 1) and in July (effective from July 1). Each revision typically increases DA by 2–4 percentage points depending on the All India Consumer Price Index for Industrial Workers (AICPI-IW). When DA crosses certain thresholds (25%, 50%, 100%), HRA rates are also revised upward. The arrears for the January revision are usually paid in March, and July revision arrears are paid in October.

DA for central government employees is calculated as a percentage of Basic Pay. DA amount = Basic Pay × DA Rate ÷ 100. For example, if your Basic Pay is ₹56,100 and DA rate is 55%, your monthly DA is ₹56,100 × 55 ÷ 100 = ₹30,855. DA is fully taxable as income. The DA rate is revised based on the 12-month rolling average of AICPI-IW index. Formula: DA% = (Average AICPI-IW for last 12 months − 115.76) ÷ 115.76 × 100. DA is paid on Basic Pay only — not on HRA or TA.

DA arrears in 2026 are calculated as: (New DA − Old DA) × Basic Pay × Number of months of arrear. For example, if DA increases from 55% to 58% and arrears are for 2 months (January and February), and your Basic Pay is ₹56,100: Monthly increase = ₹56,100 × 3% = ₹1,683. Arrear for 2 months = ₹1,683 × 2 = ₹3,366. NPS contribution also increases — 24% of the DA increase × arrear months is additionally contributed to NPS. Arrears are taxable in the year they are received, not the year they relate to — but Section 89(1) allows tax relief on arrears.

When DA crossed 50% of Basic Pay in January 2024, HRA rates for central government employees were automatically revised upward. The new rates became: X-class cities (Delhi, Mumbai, Bengaluru, Chennai, Kolkata, Hyderabad, Pune) — 30% of Basic Pay (was 27%). Y-class cities — 20% of Basic Pay (was 18%). Z-class cities — 10% of Basic Pay (was 9%). Minimum floor amounts also increased: X city ₹5,400/month (was ₹4,320), Y city ₹3,600/month (was ₹2,880), Z city ₹1,800/month (was ₹1,620). The next HRA revision will happen when DA crosses 100%.

Yes. Since NPS contribution is calculated on (Basic Pay + DA), every DA revision increases both the employee and government NPS contributions. When DA increases by 3%, the NPS impact is: Employee contribution increase = Basic Pay × 3% × 10% = Basic Pay × 0.3%. Government contribution increase = Basic Pay × 3% × 14% = Basic Pay × 0.42%. So total additional NPS contribution = Basic Pay × 0.72% per month. For a person with Basic Pay of ₹56,100, a 3% DA hike means an additional ₹404/month goes to NPS (employee ₹168 + govt ₹236). Over 30 years, this compounding has a significant impact on NPS corpus.

DA revisions for central government employees happen in January and July every year. The January 2026 DA revision has already been announced at 55%. The July 2026 DA revision will be announced in September or October 2026 and will be based on the AICPI-IW index data from January to June 2026. Based on recent trends, each revision adds approximately 2–4 percentage points. So the July 2026 revision could bring DA to approximately 57–59%. The official announcement is made by the Cabinet and published in the Official Gazette.
