Dearness allowance is the only part of a central government payslip that moves twice a year, and it moves everything it touches — gross pay, the NPS charge, transport allowance. This article sets out the rate in force today (60%, dated and sourced), the formula that produces each revision, the full notified history, and the honest position on the July 2026 instalment that has not yet been ordered.

The rate in force, date-stamped

DA stands at 60% of basic pay, effective 1 January 2026. The Union Cabinet approved the rise (from 58%) on 18 April 2026, and the Department of Expenditure, Ministry of Finance, issued the implementing Office Memorandum on 22 April 2026. Pensioners draw the same 60% as Dearness Relief. This paragraph was re-verified against the official position on 23 October 2026: no later DA order has issued. DA is calculated on basic pay alone — not on gross, not on allowances — and that single fact is the answer to most DA arithmetic questions: your DA is your matrix cell multiplied by the rate.

DA at 60% on the entry basics

The read-off runs off the entry cell of each level; your own DA is your own cell at the same 60%. On the 7th CPC Salary Calculator page, the DA rate is an input precisely so this multiplication can be re-run the day a new rate is notified.

How each revision is produced: the formula

DA revisions are not negotiated afresh each time; they fall out of a price index. The rate is set from the All-India Consumer Price Index for Industrial Workers (AICPI-IW), averaged over the twelve months ending each June and December: the average is carried to the index’s older base by the linking factor (x 2.88), compared with the fixed base figure of 261.42, and the percentage above it — fraction dropped — is the DA rate. Run on the twelve months to June 2026, whose monthly indices average 148.65, the formula gives (148.65 x 2.88 − 261.42) / 261.42 x 100 = 63.76% — which is why the July 2026 instalment is expected at 63%. Expected, not in force: a formula result becomes a rate only when the Cabinet approves it and the Department of Expenditure notifies it, and until then payslips run at 60%.

The July 2026 instalment: the honest position

The instalment due from 1 July 2026 had not been notified as of 23 October 2026 — the latest DA order on record remains the 22 April 2026 memorandum. This is later than the usual festive-season pattern (the July 2025 rise was ordered on 6 October 2025), but the mechanism is unchanged: whenever the order issues, the revised rate applies from 1 July 2026 and the difference is paid as arrears. Arrears arithmetic is simple once the rate is known: at 63%, the arrears are 3% of your basic pay for each month from July 2026 to the month before the revised salary is drawn — on the Level 7 entry basic, ₹1,347 a month (₹44,900 x 3%).

Running a hike before it lands: the da hike calculator method

Used as a da hike calculator, the method is the read-off run backwards: take your basic, multiply by the expected rate for your new DA, and by the difference in rates for the monthly gain and the arrears. On ₹44,900: DA at 60% is ₹26,940; at the expected 63% it would be ₹28,287; the monthly gain is ₹1,347, and four months of arrears (July to October) would be ₹5,388. The 7th CPC Salary Calculator runs the same scenario honestly — set its DA input to 63 and the whole payslip, NPS included, re-works at the expected rate, labelled an estimate until the order lands.

Beyond the entry cells: DA mid-column, and the rounding rule

The read-off above uses entry cells because they are the comparison everyone shares, but DA is charged on your cell. Four mid-column reference points at the same 60%: Level 6, cell 10 — basic ₹46,200, DA ₹27,720; Level 7, cell 10 — basic ₹58,600, DA ₹35,160; Level 10, cell 5 — basic ₹63,100, DA ₹37,860; Level 12, cell 5 — basic ₹91,400, DA ₹54,840. One mechanical note: the DA orders carry the standard rounding clause — a DA fraction of 50 paise or more rounds up to the next rupee, and a smaller fraction is ignored — so a cell whose 60% ends in paise is paid at the rounded figure, not the exact product. At 60% every matrix cell (all of them are multiples of a hundred) multiplies out to whole rupees, so the clause matters only when a rate with a fraction, or a non-matrix basic under a different structure, enters the calculation.

The notified series, 2016 to today

Two features of the series reward a look. The instalments of January 2020 to June 2021 were frozen at 17% during the pandemic and released together in July 2021 — the jump from 17% to 31% in one step is that release, not a single giant rise. And every revision is approved after its effective date, which is why DA arrears of two or three months are a normal part of the cycle rather than an error to query.

Who this rate is — and is not — for

This is the da calculator for central government employees position: the 60% rate binds central government employees and, as Dearness Relief, central pensioners. It does not bind state government staff (states issue their own DA orders, usually following the Centre with a lag), central public sector employees on Industrial DA (a separate, quarterly mechanism), or bank staff (whose DA runs on the bipartite settlement). If your payslip is one of those, this article’s formula section still explains the family resemblance — but your rate lives in your own employer’s order.

What DA does to the rest of the payslip

DA is a percentage of one line, but it leaks into three others. NPS is charged on basic + DA, so every DA point raises the subscription too: on the Level 6 entry cell, the NPS base is ₹56,640 — the ₹35,400 basic plus its ₹21,240 of DA — and of the 10% monthly charge of ₹5,664, exactly ₹2,124 (10% of the DA itself) exists only because DA does, which is why a DA rise never reaches your pocket undiminished. Transport allowance is drawn with DA on top of its fixed base: the Levels 3–8 base of ₹3,600 is paid as ₹5,760 at 60% DA — ₹2,160 of it is DA — and re-drawn at each revision. And HRA carries DA in its history rather than its formula: the city rates themselves stepped up when DA crossed 25% (July 2021) and 50% (January 2024), reaching today’s 30/20/10 — further DA points do not move HRA again, but the two crossings are why older payslips show smaller HRA percentages on similar basics.

Dearness Relief: the pensioner twin

Everything in this article has a pension mirror. Pensioners draw Dearness Relief at the identical percentage on their basic pension, revised on the same January/July cycle; the Department of Pension and Pensioners’ Welfare issues the DR order separately, usually within days of the employees’ memorandum. The 60% in force is therefore also the DR rate, the July 2026 calculation of 63.76% is also the DR expectation, and the arrears logic is identical — the difference between the old and new percentages, on the basic pension, for every month back to the effective date. A retired reader should read every “DA” above as “DR” and every “basic pay” as “basic pension”; the arithmetic does not change by a rupee.

Why January and July, every time

The twice-yearly rhythm is built into the formula’s inputs. Each revision averages twelve months of the price index — the months ending in December for the January instalment, the months ending in June for the July one — so a revision can never be computed before its window closes, and the index for the last month of the window is itself published a month late. Approval and notification then take their own weeks. The system therefore runs permanently a few months behind the prices it compensates, and it pays the difference as arrears when it catches up. That lag is not a malfunction to be agitated about; it is the mechanism, and the arrears are the mechanism completing itself.

DA is also the quiet hinge of the bigger story: it is the allowance a pay commission merges into basic pay when it fixes a new matrix — 125% was merged in 2016 to build the 2.57 fitment, and the DA standing at the 8th Commission’s cut-off will be one of the inputs to its factor. The rate in force is 60%; the next move belongs to a Cabinet decision that, as of the date stamped above, has not yet been taken.
