WB Primary Teachers DA Arrears Calculator under ROPA 2009: Your Complete 25% DA Arrears Tool Guide (Updated March 2026)
West Bengal Primary Teachers and other government employees have been waiting for years for their Dearness Allowance (DA) arrears under the West Bengal Services (Revision of Pay and Allowances) Rules, 2009 (ROPA 2009). In a major development in February 2026, the Supreme Court directed the state government to recalculate and release these arrears for the period 1 April 2008 to 31 December 2019. Chief Minister Mamata Banerjee announced that payments will begin from March 2026, with 25% of the total DA arrears to be cleared first by 31 March 2026 as per the court’s interim directive.WB Primary Teachers DA arrears Calculator.

If you are a Primary Teacher (or any WB government employee, aided school staff, or pensioner) under ROPA 2009, you can now estimate your exact dues using dedicated 25% DA Arrears Calculators. These online tools are designed specifically for the ROPA 2009 period and automatically apply the 25% portion that is being released first.
Under ROPA 2009, DA should have been revised in line with the statutory formula (linked to the All-India Consumer Price Index). The state’s earlier calculations created a shortfall compared to what employees were entitled to. The Supreme Court upheld that DA is a statutory right, not a discretionary benefit. Primary teachers (along with high school staff, non-teaching employees, and pensioners) are fully covered. The arrears cover the entire 2008–2019 period and include adjustments for increments, promotions, and periods without pay.
