How it is calculated
Pension is half of last pay for full qualifying service, and proportionately less for shorter service, between the minimum and maximum pension of the time — ₹9,000 and ₹1,25,000 a month under the 7th Pay Commission, ₹3,500 and ₹45,000 before it.
Last pay is the last basic drawn, or the average of the last ten months if that is higher; enter whichever applies to you.
Dearness relief is added at the rate in force, and a family pension figure is shown alongside.
Worked example
A last basic of ₹80,000 with 25 years of qualifying service on 1 August 2026: a basic pension of ₹40,000 plus dearness relief at 60% is ₹64,000 a month.
