NPS as a pension engine — the annuity focus
Most NPS calculators emphasise corpus size. This variant centres on the question that matters at retirement: how much monthly pension will my NPS corpus generate?
The widget defaults to 100% annuity — meaning the entire NPS corpus is used to purchase a lifetime pension, with no lump-sum withdrawal. This gives the maximum monthly pension from a given corpus. If you prefer a partial lump-sum alongside pension, switch to the main NPS calculator which defaults to the PFRDA minimum 40% annuity.
How the annuity converts corpus to pension
At retirement, the annuity portion of your corpus is handed to a PFRDA-empanelled Annuity Service Provider (ASP). The insurer pays you a monthly income for life (or a fixed term, depending on the variant). The relationship is:
Monthly pension = (Annuity corpus × Annuity rate %) ÷ 12
Example: Corpus ₹2.27 Cr × 100% annuity × 6% annuity rate ÷ 12 = ₹1,13,500/month
The 6% annuity rate is an assumption — actual rates from PFRDA ASPs range from 5.5% to 7% depending on the variant and insurer. Use the eNPS portal to get live quotes before purchasing.
Annuity types and the pension trade-off
| Annuity variant | Monthly payout | Corpus returned on death? | Spouse protected? |
|---|---|---|---|
| Life annuity (no ROP) | Highest | No | No |
| Life annuity with ROP | Lower (−15 to 25%) | Yes | No |
| Joint-life annuity (50% to spouse) | Lower | No | Yes — 50% continues to spouse |
| Joint-life with ROP | Lowest | Yes | Yes |
| Annuity certain (10/15/20 yr) then life | Variable | N/A | Optional |
Practical choice for most subscribers: Joint-life annuity without ROP if the spouse has no independent pension; life annuity with ROP if you want estate preservation. Get at least three ASP quotes via eNPS before committing.
Tax on monthly pension
Monthly pension received from NPS is taxable as income from other sources at your applicable slab rate. This is a structural difference from EPF and PPF (which are EEE). The accumulation is tax-deferred, not tax-exempt on the pension side.
Planning implication: if you have other taxable income in retirement (rent, FD interest, etc.), your NPS pension will be stacked on top and taxed at the marginal rate. In a nil-income scenario (NPS pension is your only income), the basic exemption of ₹3L (old regime) or ₹4L (new regime FY 2026-27 onwards) applies, meaning lower pension amounts may be effectively tax-free.
Building a pension stack alongside NPS
NPS pension is best viewed as one layer of a multi-source retirement income:
| Source | Monthly income | Tax treatment |
|---|---|---|
| NPS annuity | Variable (this calculator) | Taxable |
| EPF/EPS pension (if salaried) | Fixed by EPS formula | Taxable |
| PPF maturity invested in SWP | Flexible | Tax-free (PPF maturity) |
| Rental income | Fixed | Taxable |
| SWP from equity mutual funds | Flexible | Taxable (LTCG/STCG) |
