About the NPS Calculator
An NPS calculator estimates your National Pension System corpus at retirement and the pension it can buy. ₹5,000 a month from age 30 to 60 at 10% builds about ₹1,13,96,627. Putting 40% into an annuity at 6% pays about ₹22,793 a month.
How it is calculated
Corpus after each month = (previous corpus + this month's contribution) × (1 + i)
- i is the monthly rate: the expected annual return ÷ 12 ÷ 100.
- Monthly pension = annuity corpus × annuity rate ÷ 12.
- Lump sum = corpus − annuity corpus.
Worked example
Inputs: ₹5,000 a month from 30 to 60, 10% return, 40% annuity at 6%.
Result: Corpus ₹1,13,96,627, pension ₹22,793 a month, lump sum ₹68,37,976.
Rules and assumptions
- Since December 2025, non-government subscribers can take up to 80% of the corpus as a lump sum at exit and must use at least 20% for an annuity. Smaller corpuses have more flexible rules. Government employees still use at least 40% for an annuity.
- NPS returns depend on your asset mix and are not guaranteed. Annuity rates depend on the insurer and plan at the time you buy.
- Under the old regime, an extra ₹50,000 of your own contribution is deductible under Section 80CCD(1B). Employer contributions under 80CCD(2) are deductible in both regimes, within limits.
Frequently asked questions
How much pension will I get from NPS?
It depends on your corpus, the share you use for an annuity and the annuity rate. Monthly pension = annuity corpus × annuity rate ÷ 12.
How much can I withdraw from NPS at 60?
Non-government subscribers can withdraw up to 80% as a lump sum under the rules in force since December 2025; at least 20% must buy an annuity. Government employees can withdraw up to 60%.
What return does NPS give?
Returns vary by fund manager and asset mix. Equity-heavy choices have historically returned more over long periods, but nothing is guaranteed.
Is the NPS lump sum taxable?
A lump sum of up to 60% of the corpus at retirement is tax-free under the Income-tax Act. Check the current rules for any withdrawal above 60%. Annuity income is taxed at your slab rate.
