How DA arrears are calculated

Monthly arrears = basic pay × (new DA percent − old DA percent) ÷ 100. Total arrears = that monthly amount × the number of months you enter.

This ignores recoveries, half-pay periods, and promotions in the middle of the arrears window. If basic pay changed during those months, calculate each spell separately and add the totals.

Use the DA rates from the two office orders, not a rounded news figure, when the rupee amount matters.
Tax on arrears is not calculated here.
