Enter your current numbers — the projector runs the exact UPS assured-pension formula and an NPS corpus-and-annuity projection off the same basic pay, DA and career length.
60% is the rate effective Jan 2026 — resets every 6 months
Market-linked — your assumption, not a guarantee
Simplified — real pay moves in increments plus promotions
Total years of service
30
at projected retirement
UPS
Unified Pension Scheme
₹45,153/month
50% of average basic pay over the last 12 months, full 25+ year service
Inflation-indexed via Dearness Relief (AICPI-IW) — rises every year like a serving employee's DA.
Government contributes 18.5% of Basic+DA (10% to your individual corpus, 8.5% to a shared pool that funds this guarantee); you contribute 10%. Lump sum does not reduce the assured pension.
NPS
National Pension System
₹35,662/month
From the 40% annuity portion at 6% — not guaranteed, not inflation-indexed
Total invested (you + govt): ₹61.91 L at 10% + 14% of Basic+DA, compounding at 10% p.a.
Government contributes 14% of Basic+DA — all of it into your own corpus, none pooled. If markets underperform your assumption, this pension falls; UPS's does not.
Under these assumptions, UPS pays ₹9,490 more per month than NPS's projected annuity pension.
UPS's figure is guaranteed and rises every year with Dearness Relief. NPS's figure is fixed once you buy the annuity and depends entirely on the market returns your corpus actually achieved by retirement — a downturn right before you retire lowers it permanently, something UPS is structurally immune to. Higher NPS numbers above reflect optimistic return assumptions, not a promise.
Every simplification, stated plainly
This projector approximates your last-12-month average basic pay with a single projected final-year figure, applies one constant DA% and pay-growth rate across your entire remaining career, and ignores promotions and pay-commission revisions — real pay and DA move in irregular steps, not smoothly. NPS returns are market-linked and not guaranteed at the 10% you chose above.
This is largely a one-way decision
The original NPS-to-UPS choice was a one-time option with a final extended deadline of 30 September 2025 for most existing employees. A later Ministry of Finance office memorandum (20 August 2025) allowed employees who had already opted into UPS a one-time, one-way switch back to NPS — exercisable up to one year before superannuation — but that reversal is itself final. Verify your own eligibility window and deadline with your Drawing and Disbursing Officer, and consult a financial advisor, before switching either direction.
Rules as officially notified — not projections. Statutory rules can change; verify the current version with PFRDA or your department before deciding.
| Factor | UPS | NPS |
|---|---|---|
| Pension formula | 50% of average basic pay, last 12 months before superannuation (25+ yrs service) | No formula — depends on corpus size and chosen annuity rate at exit |
| Minimum qualifying service | 10 years for any assured pension; full 50% needs 25+ years | None — corpus builds from whatever you contribute, whenever |
| Minimum pension floor | ₹10,000/month after 10 years of service | None guaranteed |
| Family pension | 60% of employee's pension immediately before demise | Depends on the annuity plan chosen (joint-life option, if selected) |
| Inflation indexation | Yes — Dearness Relief on AICPI-IW, same basis as serving employees | No — annuity payout is fixed once purchased (unless a rare increasing-annuity plan is chosen) |
| Employee contribution | 10% of Basic+DA | 10% of Basic+DA |
| Government contribution | 18.5% total (10% individual corpus + 8.5% pool corpus) | 14% — all into your individual corpus |
| Lump sum at exit | 1/10th of monthly emoluments per 6 completed months of service, in addition to gratuity | 60% of corpus, tax-free |
| Risk profile | Government-guaranteed — no market exposure on the assured payout | Market-linked — equity, corporate debt and government securities |
| Effective from | 1 April 2025 (PFRDA regulations notified 19 Mar 2025) | 1 January 2004 |
| Switching | One-time option to join by 30 Sep 2025 (extended); one-time reversal to NPS allowed, then final | Default scheme — switching to UPS uses the same one-time option, in reverse |
Need the standalone NPS numbers instead?
This comparison simplifies both schemes to make them comparable. For a deeper NPS projection with a year-wise growth table, use the dedicated calculator.
UPS became the second retirement option for Central Government employees on 1 April 2025, alongside the market-linked NPS most had defaulted into since 2004. The pitch is a guaranteed, inflation-indexed pension instead of a corpus that depends on how equity and debt markets perform between now and your retirement date. This calculator runs both formulas off the same basic pay, DA and career-length inputs so you can see the actual rupee gap between the two — plus the contribution-rate and tax differences that never show up in a single pension figure.
UPS assured pension is a formula, not a projection: 50% of your average basic pay over the last 12 months before superannuation, for 25 or more years of qualifying service. This calculator approximates that 12-month average using your projected final-year basic pay after applying your pay-growth assumption across your remaining years of service — a simplification, since real basic pay rises in discrete annual increments and promotions, not smoothly. With 10 to 25 years of service, the pension is prorated by (years of service ÷ 25); below 10 years, UPS pays no assured pension at all. A ₹10,000/month floor applies once you clear 10 years, and the whole figure rises every year with Dearness Relief, the same inflation adjustment serving employees get.
NPS has no such formula. Your monthly pension depends entirely on the corpus your 10% employee contribution plus the government's 14% match accumulate at your chosen return rate, then splits 60% lump sum and 40% into an annuity at your chosen annuity rate. The calculator compounds that contribution monthly, growing your basic pay each year by your pay-growth assumption, the same methodology as the standalone NPS Calculator.
The two schemes also pull different amounts from the government: 18.5% of your Basic+DA under UPS (10% to your own corpus, 8.5% to a shared pool that funds the guarantee) versus 14% under NPS, all into your own account. That extra 4.5% is the price of certainty, not extra money you personally control.

Scope note: This calculator approximates your last-12-month average basic pay using a single projected final-year figure, ignores promotions and pay-commission revisions, and assumes a constant DA% and pay-growth rate across your entire remaining career — real pay and DA move in irregular steps. NPS returns are market-linked and not guaranteed at any rate you choose here. Pension decisions under UPS are largely irreversible — verify your own eligibility window and deadline with your DDO, and consult a financial advisor before switching.
