₹10,000 a month in NPS from age 30, growing at 10% a year, builds a corpus of about ₹2.28 crore at 60. With 40% put into an annuity at 6%, that is a ₹1.37 crore lump sum and ₹45,587 a month.
What this calculates
Enter your monthly contribution, your age, the return you expect, the share of the corpus you will put into an annuity and the annuity rate. This works out the corpus you will have at 60, the lump sum you take, the amount that buys the annuity and the monthly pension it pays, with a year-by-year table of growth.
The formula
Corpus
corpus = P × ((1 + i)ⁿ − 1) ÷ i × (1 + i)Split
annuity = corpus × annuity %; lump sum = corpus − annuityPension
monthly pension = annuity × annuity rate ÷ 12P is the monthly contribution, i the expected return ÷ 12 as a decimal (10% is 0.008333) and n the number of months until 60. Contributions are paid at the start of each month.
Worked example
The same ₹10,000 a month started at 25 grows to about ₹3.83 crore: five more years of contributions, compounding for longer.
When to use it, and the mistakes to avoid
Use it to plan a retirement income, to see what starting earlier is worth, or to compare NPS with EPF, PPF and a SIP.
The mistakes that cost the most:
- Treating the return as certain. It is an assumption; test a lower figure.
- Starting late. Time in the market does more than the amount: five extra years raise the corpus by about two-thirds.
- Ignoring inflation. A pension of ₹45,587 in 30 years buys far less than it does now.
- Forgetting the pension is fixed. An ordinary annuity does not rise with prices.
- Using an old annuity rule. The minimum share changed in 2025; check the latest rule.
FAQ
How much corpus will I have from NPS at 60?
It depends on how much you pay, for how long and what the scheme earns. ₹10,000 a month from age 30 at an assumed 10% a year grows to about ₹2.28 crore at 60, on ₹36 lakh paid in. Starting at 25 instead gives about ₹3.83 crore.
What share of the NPS corpus must go into an annuity?
This calculator keeps at least 40% in an annuity, the government-sector rule; the rest is paid as a lump sum. PFRDA amended the exit rules in December 2025, and reports say non-government subscribers may now put as little as 20% of a larger corpus into an annuity. Check the latest PFRDA regulations for your case.
How is the monthly pension worked out?
It is the annuity amount times the annuity rate, divided by 12. ₹91.17 lakh in an annuity at 6% pays about ₹45,587 a month. The rate depends on the annuity provider and the option you choose, so try more than one.
What return should I assume for NPS?
NPS returns follow the markets and are not guaranteed. A mix with a high equity share has returned around 10% to 12% over long periods, while safer mixes earn less. Try a lower and a higher figure to see the range, rather than relying on one.
Is the NPS lump sum taxable?
The rules have changed over time and depend on your tax regime and who you are, so this calculator does not model tax. Check the current Income Tax Department rules, and see the income tax calculator for your regular tax.
