About this tool
Project your NPS corpus at 60, the pension your mandatory annuity buys, and the real tax you save.
The NPS Calculator projects your National Pension System corpus at retirement using the monthly-compounded annuity-due formula P × [((1+i)^n − 1) ÷ i] × (1+i), then splits that corpus into the annuity portion you must buy and the lump sum you can take. It is built for salaried Indians deciding how much to put into NPS: you set your age, monthly contribution and expected return — or build the return from an E/C/G asset mix at 12%, 8% and 7% — and see the corpus, the monthly pension it buys, and the tax deduction it earns. Deductions are worked out separately under 80CCD(1), 80CCD(1B) and 80CCD(2) for the old and new regimes, with 4% cess added to the saving.

Set Current age, Retirement age and Monthly contribution, then either switch on the Asset-mix helper to blend E at 12%, C at 8% and G at 7%, or type a figure into Expected return %.
Set Annuity rate % (real quotes today sit around 6-7%) and drag Annuity purchase %, whose 40% floor is the legal minimum at 60, then choose Old regime or New regime and Your tax slab.
Read Corpus at age 60 with the formula P × [((1+i)^n − 1) ÷ i] × (1+i) spelled out, plus Annuity portion, Estimated monthly pension, Lump sum and Total invested, and What you save in tax, every year; press Copy summary.
Shows the corpus you build and the pension the mandatory 40% annuity actually pays, not just a growth number.
Applies 80CCD(1B), the 10%-of-basic ceiling on 80CCD(1) and the 10% vs 14% employer cap separately, so old and new regime results are not conflated.
Blends E, C and G returns into a single rate and flags mixes above the 75% Active Choice equity cap that PFRDA would not allow.
At least 40% at age 60 — the remaining 60% comes out as a tax-free lump sum. If the total corpus is ₹5 lakh or less the annuity requirement is waived and you can withdraw the whole amount. Exit before 60 is stricter: 80% must buy an annuity, with full withdrawal allowed only up to ₹2.5 lakh.
It is a deduction of up to ₹50,000 for your own NPS contributions, available over and above the ₹1.5 lakh combined 80C/80CCD(1) limit and only in the old regime. No other instrument — ELSS, PPF, insurance premium or home-loan principal — can be claimed against it, which is why the calculator treats it first before allocating anything to 80CCD(1).
No. The lump sum withdrawn at 60 is tax-free, but annuity income is taxed at your slab rate every year for life. This is an informational model of the current rules, not tax advice — confirm your own position with a chartered accountant before filing.
The calculator's asset-mix helper uses long-run assumptions of 12% for the E (equity) fund, 8% for C (corporate bonds) and 7% for G (government securities), blended by your chosen percentages. These are assumptions, not guarantees — NPS returns are market-linked, and you can override the blend with any manual rate.
