This free DA calculator works out your Dearness Allowance on basic pay at the current Central Government rate of 63% (from 1 July 2026) or any rate you enter. It gives:

• DA a month and a year, rounded the official way, and basic plus DA;
• DR for pensioners on basic pension;
• the DA hike from the previous rate, and DA on transport allowance;
• the HRA rate that applies at your DA, and your DA at every rate since 2016;
• the expected DA from the AICPI-IW index, using the 7th CPC formula.

DA Calculation Formula

Basic pay is the pay in your 7th CPC Pay Matrix level; special pay and other pay are not included. Under the Department of Expenditure OM dated 22 April 2026, DA with a fraction of 50 paise or more is rounded up to the next rupee and a smaller fraction is ignored. The DA rate comes from the All-India Consumer Price Index for Industrial Workers (AICPI-IW, 2016 = 100) published by the Labour Bureau; 2.88 links it to the older 2001 series used by the formula, and any fraction of a percent is ignored.

Current DA Rate and DA History (7th CPC)

The July 2026 instalment of 3% was approved on 28 October 2026 and notified by the Department of Expenditure in OM No. 1/2(i)/2026-E.II(B) of 29 October 2026; Dearness Relief for pensioners rose to 63% from the same date. The next instalment is due from 1 January 2027. The calculator's history table lists every rate from 2016.

How DA Affects HRA and Transport Allowance

• HRA: under the Finance Ministry OM dated 7 July 2017, HRA started at 24% / 16% / 8% of basic pay (X / Y / Z cities), rose to 27% / 18% / 9% when DA crossed 25%, and to 30% / 20% / 10% when DA reached 50% from January 2024.
• Transport allowance: paid at ₹7,200, ₹3,600, ₹1,800, ₹1,350 or ₹900 a month by pay level and city, with DA on top at the same rate.

Dearness Relief for Pensioners

Pensioners and family pensioners get Dearness Relief at the same rate as DA, on their basic pension before commutation. On a basic pension of ₹30,000, DR at 63% is ₹18,900 a month. See your full pension with the pension calculator.

DA Hike and Arrears

DA is revised from 1 January and 1 July each year, but the Government usually announces it a few months later, so the difference is paid as arrears. From 60% to 63% on ₹44,900 basic, the arrears are ₹1,347 for each month from July 2026. Work them out with the DA arrears calculator.
