Estimate your guaranteed pension, family pension, and lump sum under India's new Unified Pension Scheme (UPS) for central government employees.
Estimate your guaranteed monthly pension, family pension, and lump sum under India's new Unified Pension Scheme (UPS) launched for central government employees.
Launched on April 1, 2025, the Unified Pension Scheme (UPS) is a hybrid pension system designed for central government employees in India. It combines the safety of the old pension scheme (OPS) with the contribution structure of the national pension system (NPS). Under the UPS, employees receive a guaranteed pension based on their service and basic pay, rather than a purely market-linked return.
The number this calculator produces is only as good as two inputs, and both live in your service book rather than your memory. Qualifying service excludes some leave categories and any period before regularisation, so employees who joined on contract before absorption often have one or two fewer qualifying years than they assume, exactly the margin that matters near the 10-year floor or the 25-year benchmark. And the basic-pay figure is the average of the final twelve months, which means a promotion landing eleven months before retirement lifts almost the entire average, while one landing after the window opens lifts only part of it. Officers weighing voluntary retirement dates should run the calculator twice, once with the current basic and once with the expected post-increment figure, because the annual increment cycle in July can move the pension by more than the difference of retiring a quarter earlier.
The old OPS promised half your final salary with no employee contribution; NPS made you invest 10% with no promised outcome. UPS, effective 1 April 2025, splices the two: you still contribute 10% of basic plus DA every month, the government puts in 18.5%, and the outcome is guaranteed at 50% of final-year average basic rather than left to the market.
The guarantee stack has three floors: the assured pension itself, a 60% family pension for the surviving spouse, and the ₹10,000 monthly minimum for anyone with at least 10 years of service. All three index with Dearness Relief, which is the quiet superpower, a fixed private annuity loses purchasing power every year, while DR-linked payouts have historically doubled in nominal terms across a long retirement.
The pro-rating between 10 and 25 years makes each year of service worth 2% of final basic, permanently. Rajan's choice to leave at 20 rather than 25 costs ₹6,000 a month for life; discounted over a 25-year retirement with DR, that is a seven-figure decision disguised as a five-year one.
The cliff at the bottom is harsher: nine years and eleven months of service earns NO assured pension, only the accumulated corpus. Anyone near the 10-year line considering resignation should count months, not years, and anyone at 23-24 years weighing early retirement is standing on the steepest part of the curve.
The one-time switch window for existing employees closed on 30 November 2025; new recruits choose within 30 days of joining. If you switched, this calculator is now your baseline reality. If you stayed on NPS, the comparison still matters: NPS keeps market upside, a corpus compounding at equity returns can out-earn the UPS guarantee for younger employees with 30-year horizons, at the price of sequence risk exactly when you retire.
Think of it as insurance rather than investment: UPS trades expected return for certainty, and the trade is most attractive for employees within 10-15 years of retirement, risk-averse households, and anyone whose family depends on the 60% survivor benefit. It is least attractive for a 28-year-old comfortable with equity volatility, which is why the scheme is a choice and not a migration.
State government employees should check their own state's adoption status: UPS binds the centre, and states have been opting in on their own timetables, your state's notification date decides whether this calculator describes your service at all.
One number worth holding alongside the pension estimate is the lump sum: separate from gratuity, UPS pays one-tenth of monthly basic plus DA for every completed six months of service at superannuation. For Rajan's twenty years that is forty half-year blocks, a meaningful cash cushion on retirement day that does not reduce the monthly pension at all, unlike the old commutation trade-off where cash today permanently shrank the annuity.
The Unified Pension Scheme pays central government employees a guaranteed monthly pension of 50% of their average basic pay over the final 12 months of service, in full at 25 years of qualifying service and pro-rated down for 10 to 24 years, with a ₹10,000 monthly floor.
The calculator applies exactly that: your final-year average basic, your service years against the 25-year benchmark, and the floor. Dearness Relief indexation then rides on top of whatever the formula produces, which is why the guaranteed number understates what you will actually receive over a long retirement.
Rajan retires from a central ministry after 20 years with an average final-year basic of ₹60,000, a typical Group B profile.
Twenty years is short of the 25-year benchmark, so his rate scales: 50% x (20/25) = 40%.
Pension: ₹60,000 x 40% = ₹24,000 a month, guaranteed for life, with DR adjustments on top.
Had he stayed the extra five years, the full 50% would pay ₹30,000, those five years are worth ₹6,000 a month for the rest of his life, plus whatever pay rises the final years bring into the averaging window.
If Rajan dies before his wife, she continues to receive 60% of his pension, ₹14,400 a month, without any insurance policy doing the work.

| Parameter | Definition & Context |
|---|---|
| Average Basic Pay | Monthly basic plus DA averaged over the final 12 months of service, the single biggest lever in the formula. |
| Years of Service | Qualifying service only. 10 years is the door to any assured pension; 25 unlocks the full 50% rate. |
