How AICPIN drives the DA rate
Dearness allowance is not a discretionary bonus — it is an index-linked formula. The Labour Bureau publishes the All-India Consumer Price Index for Industrial Workers (AICPIN-IW) every month, and the DA rate is computed from its 12-month average:
261.42 is the index base fixed when the 7th CPC matrix took effect. Because the formula uses a rolling 12-month average, the next revision is largely predictable a couple of months in advance — by the time the last index print arrives, analysts can usually call the rounded percentage. That is how the January 2026 revision (which landed at +2 points, to 60%) was anticipated ahead of the official order. It remains unofficial until the Department of Expenditure issues the order.
The twice-yearly DA cycle
Revisions are effective 1 January and 1 July each year. The Union Cabinet typically approves the January revision around March and the July revision around October — the January 2026 order followed this pattern, landing on 22 April 2026. The intervening months are paid as arrears — automatically, with the first salary after the order. A serving employee on a basic pay of ₹35,400 would, for a +3 point revision, see a monthly difference of ₹1,062; if the order lands 3 months after the effective date, that is ₹3,186 of arrears in one credit. Pensioners get the matching dearness-relief (DR) arrears on basic pension.
DA from July 2026: what to expect (as of August 2026)
The January 2026 DA hike is confirmed at 60%. The next cycle, effective 1 July 2026, has no published AICPIN average and no official order yet as of August 2026 — the Cabinet typically approves the July revision only around October. Recent revisions have added 2–4 percentage points each cycle; the table and calculator above use 63% purely as an illustrative planning figure, not a forecast. This page is updated against DoE orders as they are issued.
DA and the 8th Pay Commission
Every pay-commission revision resets DA to zero: the accumulated allowance is absorbed into the new basic pay through the fitment factor, and the index base is reset so DA starts climbing again under the new matrix. That is why "60% DA" and "8th CPC hike" are two sides of one calculation — to see them combined on your own pay, use the 8th Pay Commission salary calculator, or the pension calculator if you are a pensioner.
