DA Arrears Calculator
When your DA rate changes, the difference for the months already paid at the old rate is arrears. Enter your basic pay and how many months the old rate applied for.
Your arrears for 6 month(s) at the old rate: ₹5,388
(₹898/month difference)
This is a whole-month comparison, not prorated by day — if the rate changed partway through a payroll month, check your department's exact payroll cut-off before relying on this figure for a precise claim.

Confirmed directly against the source document above. Directly read from the OM PDF (same scanned-document caveat as above — WebFetch's text extraction fails on it, but it was read and rendered correctly). Confirms: DA enhanced from 58% to 60% of Basic Pay, effective 1 January 2026, signed by Samir Kumar Das, Deputy Secretary — and explicitly references the 58% entry's own OM (1/4(i)/2025-E.II(B), 6 Oct 2025) as its prior order, which is how that OM number was found. The AICPI-IW figure of 148.6 is NOT cited in this OM (it never mentions AICPI numbers at all) and remains a secondary-sourced figure from a different publisher (Labour Bureau) — primary verification of the rate itself does not resolve this.
Assumes: Arrears = (new monthly DA − old monthly DA) × number of months. Both rates must exist in the verified rate history below the DA calculator.
