NPS vs UPS Pension Calculator

Employee Service Details

Enter your service start, end, and basic pay at joining

Year of Joining Service The year the employee first entered central govt service.

Year of Retirement (superannuation) Typically age 60. E.g. born 1974 → retires 2034.

Basic Pay at Joining (₹/month) Actual basic pay on joining day — already post-commission if joining under a live PC. E.g. ₹18,000 = 7th CPC Level 1.

Annual Increment Rate (% of basic) Standard: 3% per year under 7th CPC. Applied every year except Pay Commission years.

Pay Commission Schedule

Add every Pay Commission that falls during service — unlimited commissions supported

How it works: Between commissions, basic grows by 3% per year. When a PC arrives: New Basic = Accumulated Basic × Fitment Factor — the accumulated basic already has years of 3% increments baked in. DA resets to 0% (fitment absorbs all existing DA). Annual increment is skipped that year. Do not add a PC for the joining year — your joining basic already reflects it.

DA at Joining (% of basic) DA% on the day of joining. Usually 0% if joining just after a Pay Commission.

DA Annual Growth (percentage points added per year) DA grows ~4–6 pp/year (AICPI-IW). Resets to 0 with each Pay Commission.

NPS — Contribution & Investment

National Pension System parameters

Employee Contribution (% of Basic+DA)

Govt Contribution — NPS (% of Basic+DA) 14% for central govt (post-2019 rule)

Expected NPS Return (% p.a.) Historical: 9–11% equity fund. Use 7% for conservative estimate.

Annuity Rate (% p.a. on remaining corpus) LIC / HDFC Life annuity: 5–7% p.a.

Lump Sum at Retirement (%, max 60) 60% of corpus can be withdrawn tax-free. Rest → annuity.

Annuity Annual Growth (% p.a.) 0 = flat annuity (most plans). Some offer 1–3% annual increase.

UPS — Unified Pension Scheme

Effective April 1, 2025 — for Central Govt employees

Govt Contribution — UPS (% of Basic+DA) 18.5% under UPS vs 14% under NPS — a key advantage

Minimum Pension Guarantee (₹/month) ₹10,000/month floor if 10+ years service

Family Pension (% of employee pension) 60% to legally wedded spouse on employee's death

Inflation & Post-Retirement Assumptions

Used to calculate real (purchasing-power) values

Consumer Inflation (% p.a.) India CPI avg: 4–6% p.a.

Post-Retirement Life (years) Retire at 60, live to 85 = 25 years

Discount Rate (% p.a.) 10-yr Govt bond yield. For present-value calculations.

UPS Dearness Relief Growth (pp/yr) DR on UPS pension grows ~4 pp/yr, protecting purchasing power.

Inflation-Adjusted Values — In Today's Rupees

True purchasing power comparison

₹30,000/month in 2035 buys far less than ₹30,000 today. These values convert all future money back to today's purchasing power. UPS pension grows with DR, so it holds value better than a flat NPS annuity over a long retirement.
