Unified Pension Scheme vs NPS vs Old Pension: Who Is Richer at 60?

The government offered a guaranteed pension and almost nobody took it#

The Centre built a scheme that pays half your final salary for life, adjusted for inflation, backed by the sovereign. It opened the door to roughly 23 lakh central government employees, then extended the deadline twice.

About 95% of them stayed where they were.

Replying in the Lok Sabha on 3 August 2026, Finance Minister Nirmala Sitharaman put the number of Unified Pension Scheme subscribers at 1,18,195 as on 19 July 2026, counting new recruits, serving staff who migrated and past retirees together. The window for exercising the option closed on 30 November 2025. The same reply said there is no proposal under consideration to alter or replace the scheme.

That is a strange outcome for a guarantee. Unions spent two decades campaigning to get the old pension scheme back. When something close to it arrived, most eligible staff read the fine print and declined.

The reason is arithmetic, and it applies well beyond government service. Anyone weighing a guaranteed income against a market-linked pot faces the same question.

Three schemes, three completely different promises#

The three schemes are not variations on a theme. They run on opposite principles.

The old pension scheme, now governed by the Central Civil Services (Pension) Rules, 2021, is what pension economists call defined benefit. The employee contributes nothing. On retirement the government pays 50% of emoluments or average emoluments, whichever is more beneficial, subject to a minimum of ten years of qualifying service, and keeps paying it for life. The 2021 rules set a floor of Rs 9,000 a month and a ceiling of Rs 1,25,000. Ordinary family pension runs at 30%, at an enhanced 50% for an initial period. Up to 40% of the pension can be commuted for a lump sum. The rules cover those appointed on or before 31 December 2003, with a few narrow exceptions, which is why this argument exists at all.

The National Pension System is defined contribution, the exact opposite. Nothing is promised. The employee puts in 10% of basic pay plus dearness allowance, the government puts in 14%, and the money goes into a personal account invested in market instruments. Whatever it grows to is your pension. At 60 you take up to 60% as cash and must convert at least 40% into an annuity.

An annuity is where most NPS disappointment lives. You hand an insurer a lump sum and it pays you a fixed monthly amount until you die. The rate it offers, currently around 6% a year, is the whole ball game, and a plain annuity never raises that figure again.

The Unified Pension Scheme sits between the two and belongs to neither. It was notified by the Department of Financial Services on 24 January 2025, operationalised by PFRDA regulations dated 19 March 2025 and came into effect on 1 April 2025. Technically it is an option inside NPS. Practically it tries to deliver an old-pension-style outcome through a contributory account.

What UPS actually promises, and the ratio buried in the formula#

The headline is clean. After 25 years of qualifying service you get 50% of the average basic pay of your last twelve months, with dearness relief added on top as the government notifies it. Ten years earns a floor of Rs 10,000 a month. On death, the spouse gets 60% of the payout, double the old scheme's 30%. There is also a lump sum of one tenth of last drawn basic pay plus dearness allowance for every completed six months of service.

The formula PFRDA publishes is A = (½ of P) × (Q/300), where P is that twelve-month average basic pay and Q is qualifying service in months, capped at 300.

Two things in it deserve more attention than they get.

The first is the cap. Three hundred months is 25 years, and nothing beyond it counts. Someone who joins at 25 and retires at 60 serves 35 years and draws exactly the same 50% as a colleague who served 25. The last decade adds to the lump sum and the corpus, but not a rupee to the assured payout. Below 25 years the payout is proportionate, and it does not apply at all under 120 months. A late entrant with 15 years gets 50% × 180/300, which is 30% of final basic pay.

The second is a multiplier that never appears in the official headline. The scheme compares your individual corpus, the actual money in your account, against a benchmark corpus, what that account would have been worth had it followed the default investment pattern PFRDA prescribes. At superannuation the individual corpus moves to the pool up to the benchmark value. If yours is higher, the balance is credited to you. If it is lower, you may top up the gap yourself, and if you do not, the payout shrinks in proportion.

So the working formula, as freefincal sets it out, is closer to (P/2) × (Q/300) × (IC/BC). On a calculated pension of Rs 25,000, a corpus ratio of 0.8 pays Rs 20,000.

The guarantee is real, but it depends on your account keeping pace with a notional account you do not control. Miss contributions, take a withdrawal, or sit in a fund that lags the default pattern, and the assured half of your salary quietly becomes less than half.

The 4.5% you hand over for the privilege#

Under NPS the government's 14% goes entirely into your account. Under UPS the government contributes 10% into your account and an estimated 8.5% of basic pay plus dearness allowance, on an aggregate basis, into a shared pool corpus that funds the guarantee across all subscribers. Add those up and the government is spending 18.5% on a UPS subscriber against 14% on an NPS one, which is how the scheme gets described as more generous.

From your side of the table the picture inverts. Your own account receives 20% of pay under UPS and 24% under NPS. The extra 8.5% is real money, paid by the exchequer, buying insurance against market risk. It just does not compound in your name.

Four percentage points of pay, invested across a 35-year career, is a large number. It is the number a UPS subscriber trades away for certainty.

Whether the trade is good depends on what markets do, and the ten-year record is not one-sided. As on 18 September 2026, NPS Scheme E Tier I has delivered ten-year returns between 10.77% and 12.14% across pension fund managers, with Scheme C between 7.23% and 7.85% and Scheme G between 6.87% and 7.63%. Those ten-year ranges cover only the funds with a decade of history, so three newer managers are absent. The same table shows why guarantees appeal: over the last twelve months, every single equity scheme is negative, from 2.77% down to 9.21%. Anyone who retired this quarter on a market-linked pot found out what sequence risk means.

The comparison, side by side#

The table below uses one illustration throughout: a final twelve-month average basic pay of Rs 1,00,000 and at least 25 years of qualifying service. The UPS and OPS figures follow the published rules. The NPS figures are my own arithmetic from those rules and are marked as such.

Sources for the scheme columns: CCS (Pension) Rules, 2021, PFRDA on UPS and the UPS gazette notification of 19 March 2025, and PFRDA on NPS for central government.

One row in that table does more work than the rest, and it is the inflation row.

Dearness relief deserves more respect than it usually gets. The Cabinet raised it to 60% of basic pay and pension with effect from 1 January 2026, covering 50.46 lakh employees and 68.27 lakh pensioners at a cost of Rs 6,791.24 crore a year. In plain terms, a pensioner whose basic pension is Rs 50,000 draws Rs 80,000 a month today, and that will keep climbing.

A plain NPS annuity does not climb. At 5% inflation, a fixed Rs 50,000 a month is worth roughly Rs 18,800 in today's money after twenty years, and a 60-year-old today has a fair chance of living to see it.

Which suggests the strongest case for UPS is not the guarantee at all. It is the indexation that sits on top of it, and that is the part the marketing tends to bury under the 50%.

Tax, the pay commission, and what neither scheme tells you#

Tax used to be the big unknown and no longer is. The Department of Financial Services released FAQs on 23 September 2025 confirming that NPS tax benefits apply to UPS. Your 10% gets a deduction under section 80CCD(1) and the government's 10% under 80CCD(2). The 8.5% pool contribution is not treated as your income at all. The retirement lump sum is exempt under section 10(12AB), a final withdrawal of 60% of the individual corpus under section 10(12AA), and the monthly payout is taxed as salary. That last point matters: a UPS or OPS pension is taxable income every year of your retirement, while 60% of an NPS corpus arrives tax free in one go.

Then there is the 8th Central Pay Commission. The Cabinet cleared its terms of reference on 28 October 2025, giving the commission 18 months from the date of its constitution to report. Those terms include a review of pension schemes, and of the unfunded cost of non-contributory ones. Note that the widely quoted 1 January 2026 effective date is an expectation drawn from the ten-year cycle, not an announced decision, and any implementation would be retrospective.

That is not a neutral fact. OPS and UPS both pay a percentage of basic pay, so a commission that raises basic pay raises those pensions mechanically. An NPS corpus gets no such revision. It benefits only from the higher contributions a higher salary produces, which helps an employee with twenty years left and does very little for one retiring in 2027. Near the end of a career, the pay commission cycle tilts the comparison towards the defined benefit schemes, and how far it tilts will not be known until the report lands.

Two caveats before anyone reads a recommendation into any of this. The switching window is shut, so for most serving employees the question is now what they hold rather than what to choose. And UPS has run for less than eighteen months. The government told Parliament that no formal performance review has been conducted since it became operational, which means nobody, itself included, has watched a full cohort retire under it.

Key takeaways#

1. The guarantee is conditional. The UPS assured payout is multiplied by the ratio of your individual corpus to a notional benchmark corpus, so a lagging account produces a smaller than advertised pension.
2. Your personal account grows slower under UPS. The government contributes 10% to it instead of 14%, with about 8.5% going to a shared pool that funds the guarantee rather than your balance.
3. Qualifying service stops counting at 300 months. Thirty five years of service earns the same 50% payout as 25, though the lump sum and corpus keep building.
4. Indexation, not the 50%, is the real prize. Dearness relief reached 60% of basic pension from 1 January 2026, while a plain NPS annuity never rises and loses roughly two thirds of its purchasing power over twenty years at 5% inflation.
5. The market cuts both ways. NPS equity schemes returned 10.77% to 12.14% over ten years to 18 September 2026 and were negative over the last twelve months, which is precisely the risk a UPS subscriber is paying to avoid.

Frequently asked questions#

Can I still switch from NPS to UPS? No. The extended window closed on 30 November 2025, and the Finance Ministry told the Lok Sabha in August 2026 that no proposal to alter or replace the scheme is under consideration. Fresh recruits are enrolled under the rules applicable at appointment.

Is UPS the old pension scheme brought back? No. It pays a similar 50% with dearness relief, but you contribute 10% of pay, the payout is tied to your corpus through the benchmark ratio, and service beyond 25 years earns nothing extra. The old scheme is non-contributory and closed to anyone appointed from 1 January 2004.

Can a UPS subscriber go back to NPS? Yes, once. The Central Civil Services (Implementation of UPS under NPS) Rules, 2025 allow a one-time, one-way switch back to NPS, but it has to be exercised at least one year before superannuation, or three months before voluntary retirement. The final year before retirement is a cut-off, not a window. The switch is barred where disciplinary proceedings are pending or contemplated, and there is no route back to UPS afterwards.

What happens if my UPS corpus falls short of the benchmark? You can arrange an additional contribution to close the gap. If you do not, the assured payout is reduced in proportion to the shortfall.

Does UPS pay the Rs 10,000 minimum to everyone? Only after a minimum of ten years of qualifying service, and PFRDA conditions it on contributions having been made on time with no withdrawals.

Which scheme is better for someone joining government service today? It depends on things nobody can settle for you: how long you expect to stay in government, whether you would move to the private sector, and how you feel about market risk. The long career, the low tolerance for volatility and the value placed on indexation all point one way. Portability, the 60% tax-free lump sum and a longer runway for compounding point the other. This article is not advice on which to pick.

Do state government employees get UPS? The 2025 rules cover central government civil employees. Several states run their own arrangements and a few have restored older schemes, so state staff should check their own government's notification rather than assume the central rules apply.

Glossary#

Defined benefit. A pension where the payout is fixed by a formula, usually a share of final salary, and the employer carries the investment risk. The old pension scheme works this way.

Defined contribution. A pension where only the contributions are fixed. The final amount depends on investment returns, and the employee carries the risk. NPS works this way.

Qualifying service. The completed months of regular central government service counted towards pension, certified by the head of office. Under UPS it is capped at 300 months for the payout formula.

Individual corpus. The actual balance in your UPS or NPS account, built from employee and employer contributions plus investment returns.

Benchmark corpus. A notional balance representing what your UPS account would be worth under the default investment pattern set by PFRDA. Your payout is scaled by how your real corpus compares with it.

Pool corpus. The shared fund, financed by the government's additional contribution of roughly 8.5% of pay, from which UPS guarantees are met.

Dearness relief. The inflation-linked addition to a pension, revised twice a year using the same formula as dearness allowance for serving staff. It stood at 60% of basic pension from 1 January 2026.

Annuity. A contract with an insurer that converts a lump sum into a monthly income for life. NPS requires at least 40% of the corpus to buy one at exit.
