WB DA Calculation Formula: The West Bengal government has officially laid its cards on the table regarding the long-standing DA dispute. In a detailed affidavit submitted to the Supreme Court-appointed monitoring committee, the state has outlined its specific mathematical formula and a status report for clearing arrears spanning from 2008 to 2019.
This development follows the Supreme Court’s February 5, 2026, verdict, which mandated the state to release the first 25 percent of pending DA arrears by March 31, 2026. To ensure strict compliance, a high-level monitoring committee headed by former Supreme Court judge Justice Indu Malhotra was constituted. The state is now required to submit regular weekly updates and financial breakdowns to this committee.

The State’s New DA Calculation Formula
According to the official submission, the government is treating the 2008–2019 period as the effective cycle for DA calculations under the ROPA 2009 framework. A critical component of this calculation is the ‘Base Index.’ The state has fixed this at 605, which represents the 12-month average of the All India Consumer Price Index (AICPI, Base 1982=100) from January to December 2007.
The calculation formula adopted by the state is: DA = (Average of last 12 months AICPI Index – 605) ÷ 605
The government’s logic is that any inflationary impact prior to 2008 was already neutralized under the previous pay commission. Consequently, they argue that the DA calculation for ROPA 2009 must start afresh from April 1, 2008, using the 2007 average of 605 as the new baseline.
The AICPI vs. WB CPI Contention
A significant twist in the report is the introduction of the West Bengal Consumer Price Index (WB CPI) alongside the national index (AICPI). The state contends that based on regional price trends, a neutralization of 85 percent is more logical than the standard 100 percent. Experts view this as a strategic move to potentially reduce the total arrear liability by 15 percent. Furthermore, the government highlighted “fiscal stability” concerns, suggesting that the massive debt burden makes full payment difficult. The lack of digitized historical records was also cited as a hurdle in the disbursement process.
Current Status of Arrear Payments
Despite the ongoing mathematical debates, the government claims that the disbursement process is already underway:
- Direct bank transfers have been initiated for numerous employees across Groups A, B, C, and D.
- A special mechanism has been activated to settle the dues of deceased employees and their families.
- Approximately ₹1,400 crore has already been released for pensioners and family pensioners.
How This Affects Government Employees
The financial implications for state employees are significant. If the Supreme Court and the monitoring committee accept the state’s 605 base index and the 85 percent neutralization theory under the WB CPI, the final payout will be much lower than initially anticipated. For many, this could result in a substantial financial loss when calculated over the ten-year arrear period.
Next Steps for the Monitoring Committee
The Justice Indu Malhotra Committee is currently reviewing weekly reports from the state, detailing exactly how much has been paid and to how many beneficiaries. The next crucial meeting of the committee is set for April 27, 2026. Interestingly, the state’s report includes a comparative analysis of DA rates in states like Kerala, Telangana, Manipur, and Tripura—a move that some believe is intended to justify the state’s stance and potentially prolong the legal proceedings.
