What is NPS?
National Pension System (NPS) is a market-linked retirement scheme administered by PFRDA. You contribute monthly during your working years; the money is invested across equity (E), corporate debt (C), government bonds (G), and alternates (A) according to your chosen allocation. At age 60, you withdraw 60% as a tax-free lumpsum and use the remaining 40% to buy an annuity that pays monthly pension for life.
For salaried earners in the 30% tax slab, NPS offers an additional ₹50,000 deduction under Section 80CCD(1B) — above and beyond the regular ₹1.5 L 80C limit. That's roughly ₹15,000/year of tax saved, on top of the long-term equity-driven growth.
How is NPS maturity calculated?
NPS uses market-linked compounding, so the maturity formula is a future-value-of-annuity:
Maturity = monthly_contribution × [((1 + r/12)^n − 1) / (r/12)] × (1 + r/12)
where r is the annualized return and n is total months till age 60. CalcMaster iterates month-by-month for accuracy.
Worked example
Age 30, ₹5,000/month contribution till 60, expected 10% annualized return:
- Months: 360
- Total invested: ₹18 L
- Maturity corpus: ~₹1.13 cr
- 60% lumpsum (tax-free): ₹68 L
- 40% annuity: ₹45 L → ~₹22,500/month pension at 6% annuity rate
Tax benefits
| Section | Cap |
|---|---|
| 80CCD(1) — your contribution | ₹1.5 L (within 80C) |
| 80CCD(1B) — additional NPS | ₹50,000 above 80C |
| 80CCD(2) — employer contribution | 10% of basic (uncapped) |
The ₹50,000 80CCD(1B) is the single best NPS feature — pure additional deduction that no other instrument offers.
Tier-1 vs Tier-2
- Tier-1: locked till 60 (with restrictions). Gets all tax benefits.
- Tier-2: fully liquid (withdraw anytime). No tax benefits, no lock-in.
Most subscribers use Tier-1 only.
Considerations
- Annuity pension is taxable at slab rate (the 60% lumpsum is tax-free).
- Choose active vs auto choice for allocation. Auto reduces equity exposure as you age; active lets you set it manually.
- Premature exit after 5 years allowed: 20% lumpsum (taxable), 80% buys annuity.
Limitations
- The calculator assumes constant return over 30+ years. Real NPS returns have varied 8–13%.
- Doesn't model the annuity purchase math (which depends on annuity provider's rates at retirement).
- Doesn't model employer's 80CCD(2) contributions separately.

Final note. NPS is the most tax-advantaged retirement vehicle for high earners after EPF. The extra ₹50,000 deduction under 80CCD(1B) is free money if you're in the 30% slab. Start at 30, stop checking the balance, and let it compound till 60.
