What Are DA Arrears?

When a revised DA rate takes effect from an earlier date but the increased amount is paid later, eligible employees may receive the difference for the applicable period as arrears.

DA Arrears Calculation Example

Suppose Basic Pay is ₹35,400, the old DA rate is 50%, the revised rate is 53%, and the difference is payable for six months.

₹35,400 × (53 − 50) ÷ 100 = ₹1,062 per month
₹1,062 × 6 months = ₹6,372 estimated arrears

When This Simple Calculation May Differ

Actual arrears can differ if Basic Pay changed during the period because of annual increment, promotion, pay fixation, retirement or another applicable event. Other allowance or deduction adjustments may also be handled separately.
