Your NPS today, your pension at 60.NPS calculator: your corpus at 60, the lump sum and the pension.

How to use the NPS calculator

1. Enter your monthly contribution and your age today.
2. Pick an expected return a year until 60, and the share of your corpus you plan to use to buy an annuity.
3. Enter an annuity rate and the inflation you expect. Then see your corpus at 60, the lump sum, and the monthly pension in future money and in today’s money.

How to read your result

Corpus at 60 is what your contributions may grow to. Lump sum is the part you can take out at 60. Monthly pension is what the annuity may pay each month, and in today’s money shows what that pension could buy at today’s prices.

For example, ₹5,000 a month from age 30, at an assumed 10% a year, may grow to about ₹1.14 crore by 60. If 40% buys an annuity at an assumed 6% rate, the pension is about ₹22,800 a month, and the lump sum is about ₹68 lakh. At 6% inflation, that pension is worth only about ₹4,000 a month in today’s money.

The rules on how much you must use for an annuity, and how much you can take out, are set by PFRDA and can change, so check the current rules before you plan around them. Annuity rates are set by insurance companies when you buy, and they differ from plan to plan. We don’t offer NPS; this calculator is here to help you plan.

A fixed pension loses value as prices rise, so many families plan other income alongside it. See the retirement calculator for the full picture, or the SWP calculator for a monthly income from mutual funds. Our retirement planning page explains how we help.

How the NPS calculator works

Your monthly contributions grow like a SIP until you turn 60. At 60, the share you choose buys an annuity, a plan from an insurance company that pays you a regular pension, and the rest is your lump sum. The pension is the annuity amount times the annuity rate, paid monthly. To show what it’s worth today, it is brought back by inflation. P is the monthly contribution, i is the yearly return divided by 12, n is the months until 60, a is the annuity share and f is inflation.

Corpus at 60 = P × ({[1 + i]^n − 1} ÷ i) × (1 + i); Annuity amount = Corpus × a; Lump sum = Corpus − Annuity amount; Monthly pension = Annuity amount × annuity rate ÷ 12; In today’s money = Monthly pension ÷ (1 + f)^(60 − age)
