7th CPC formula: DA % = [(12-month average CPI-IW × 2.88) − 261.42] ÷ 261.42 × 100; the fraction is dropped. Each row's DA % uses the 12 months ending that month, so the June and December rows give the DA from July and January. Latest released: Sep 2026 = 155.5 (Labour Bureau). Unofficial estimate — the Government notifies the final rate.

📘 About the DA Calculator

The 7th Pay Commission DA is set from the All-India Consumer Price Index for Industrial Workers (CPI-IW, base 2016 = 100): DA % = [(12-month average × 2.88) − 261.42] ÷ 261.42 × 100, with the fraction dropped. The July DA uses July–June, and the January DA uses January–December.

The input card shows the last 12 released months with the DA % each gives. Below it are the six months of the current half-year: months already released carry the published value; months not released yet carry a projection (the latest value plus the average monthly rise of recent months). Edit any box with your own estimate.

The result shows the expected DA, the exact percentage, the change from the current DA and — if you enter your basic pay — the extra DA per month and likely arrears.

🧮 Formula

12-month average (2001 base)
Average = (sum of 12 monthly CPI-IW values ÷ 12) × 2.88
DA percentage
DA % = (Average − 261.42) ÷ 261.42 × 100

Where

  • CPI-IW = All-India Consumer Price Index for Industrial Workers, base 2016 = 100
  • 2.88 = linking factor between the 2016 and 2001 series
  • 261.42 = 7th CPC base index
  • The 12 months are January–December for January's DA and July–June for July's DA
DA is notified as a whole number: the fraction is dropped (67.45% → 67%).

The Labour Bureau releases each month's CPI-IW around the last working day of the following month (e.g. September's at the end of October).

Why are some months "projected"?

Those months are not released yet. They start at the latest value plus the average monthly rise of the last few months; you can change them.

When is the new DA announced?

Usually in March (for January) and in September–October (for July), with arrears for the months already paid at the old rate.
