What is an NPS calculator?
A National Pension System (NPS) calculator estimates how your monthly Tier-1 contributions could grow until the normal exit age of 60. NPS is a market-linked retirement scheme regulated by PFRDA; returns depend on your asset mix across equity, corporate bonds, and government securities.
Anyone aged 18 to 60 can subscribe. The tool shows total invested, estimated returns, maturity corpus, and the mandatory 40% annuity / 60% lump sum split at normal exit—illustrative figures only, not guaranteed market performance.
How can an NPS calculator help you?
Most subscribers want a rough corpus number before locking money until 60. A calculator turns your monthly contribution and assumed return into a retirement target you can compare against EPF or mutual fund SIPs.
- Estimate NPS corpus from current age and monthly Tier-1 contribution.
- See total principal deployed versus compounded returns over remaining working years.
- Preview the 60% tax-free lump sum and 40% annuity corpus required at normal exit.
How does this NPS calculator work?
NPS uses compound interest on recurring deposits. Each monthly contribution earns returns until age 60. This tool applies monthly compounding at annual rate ÷ 12, with deposits credited at the end of each month using the standard ordinary-annuity method.
A = P × (1 + r/n)^(n×t) per deposit; FV = P × [((1 + r/12)^m − 1) / (r/12)]
Where –
| P | Monthly contribution |
|---|---|
| r | Expected annual return as a decimal |
| n | Compounding periods per year (12 for monthly) |
| t | Years until retirement (60 − current age) |
| m | Total months of contribution (12 × t) |
At normal exit (age 60), up to 60% may be withdrawn as lump sum; at least 40% must fund an annuity for monthly pension.
Worked example
If you are 34 years old and invest ₹3,000 each month for 26 years until age 60, total principal is ₹9,36,000 (₹3,000 × 12 × 26). At a 10% expected return, the maturity corpus is about ₹44,35,007—roughly ₹34,99,007 in compounded returns.
On that corpus, up to ₹26,61,004 (60%) could be taken as lump sum and at least ₹17,74,003 (40%) would go toward purchasing an annuity for post-retirement pension.

What this calculator does not include
Employer contributions under Section 80CCD(2), Tier-2 NPS, tax deductions (80CCD(1) and 80CCD(1B)), fund-management charges, annuity purchase rates, partial withdrawals, premature exit rules, and year-by-year NAV movement are not modeled. One constant return assumption is used throughout.
Frequently asked questions
What is the minimum and maximum NPS contribution?
Tier-1 NPS requires at least ₹500 per contribution and ₹1,000 per financial year. There is no statutory maximum, though tax benefits under Section 80C and 80CCD(1B) apply only up to prescribed limits.
How is the lump sum vs annuity split calculated?
At normal exit on turning 60, PFRDA rules require at least 40% of the corpus to buy an annuity and allow up to 60% as a tax-free lump sum. This calculator applies those percentages to your projected maturity amount.
Is NPS return guaranteed?
No. NPS is market-linked. The expected return you enter is an assumption for planning only. Actual corpus depends on asset allocation, fund performance, and charges over your subscription period.
