How do I use the NPS calculator?

1. Enter your monthly contribution: Add the amount you plan to contribute to NPS every month. A steady monthly contribution is treated like a SIP into the selected NPS investment mix. 2. Set the expected return: Enter the annual return you want to assume. NPS returns are market-linked, so use a conservative long-term assumption rather than a recent one-year return. 3. Confirm your current and retirement age: The calculator uses the gap between these ages to determine the total number of monthly contributions and whether the exit is modeled as normal retirement or premature exit. 4. Choose the annuity percentage: Select the share of corpus used to buy an annuity. The calculator applies the relevant minimum annuity floor when the modeled rule band requires it. 5. Review corpus, lump sum, and pension: Compare the total invested amount, projected retirement corpus, lump sum, annuity corpus, and estimated monthly pension based on a 6% annuity yield assumption.

How is the retirement corpus estimated?

The calculator applies a monthly SIP future value formula using your monthly contribution, expected annual return, and years remaining until retirement.

How is monthly pension estimated?

Monthly pension is estimated using a 6% annual annuity yield assumption on the annuity corpus. Actual payouts can vary by annuity provider and selected plan type.

Can I withdraw all corpus as lump sum?

Not always. In this non-government NPS Tier I model, full withdrawal is allowed up to ₹5 lakh on premature exit and up to ₹8 lakh on normal exit. Above that, current rules can require annuity purchase or other retirement-income options depending on the exit band.

Does this include tax impact or inflation?

No. This is a projection tool focused on corpus and pension estimation. It does not adjust for tax treatment, inflation, or changing returns over time.

About the NPS calculator

The National Pension System (NPS) is a long-term retirement account where regular contributions compound until exit. This calculator projects your Tier I corpus using a monthly contribution, expected return, current age, retirement age, and annuity selection.

Use it to understand the balance between contribution discipline, investment return, and the annuity split that may shape your retirement income. It is especially useful for salaried professionals, self-employed investors, and families planning a retirement corpus alongside EPF, PPF, mutual funds, and other assets.

The projection is an estimate. It assumes a constant return and applies a simplified non-government NPS Tier I exit model, including full withdrawal bands and annuity floors used by the calculator. Actual NPS returns, annuity rates, tax treatment, and exit options can differ by regulation and provider.

Frequently Asked Questions

Enter your monthly contribution
Add the amount you plan to contribute to NPS every month. A steady monthly contribution is treated like a SIP into the selected NPS investment mix.
Set the expected return
Enter the annual return you want to assume. NPS returns are market-linked, so use a conservative long-term assumption rather than a recent one-year return.
Confirm your current and retirement age
The calculator uses the gap between these ages to determine the total number of monthly contributions and whether the exit is modeled as normal retirement or premature exit.
Choose the annuity percentage
Select the share of corpus used to buy an annuity. The calculator applies the relevant minimum annuity floor when the modeled rule band requires it.
Review corpus, lump sum, and pension
Compare the total invested amount, projected retirement corpus, lump sum, annuity corpus, and estimated monthly pension based on a 6% annuity yield assumption.

FV = P × [((1 + r)ⁿ − 1) / r] × (1 + r)

FV is the projected NPS corpus at exit
P is the monthly NPS contribution
r is the monthly rate of return (annual return ÷ 12, as a decimal)
n is the number of monthly contributions (years to retirement × 12)
Annuity corpus = FV × applied annuity percentage
Monthly pension = annuity corpus × 6% ÷ 12

The applied annuity percentage may be higher than the percentage you enter if the modeled non-government Tier I exit rule requires a minimum annuity purchase.

Worked example

Suppose you contribute ₹5,000 per month from age 30 to age 60, assume a 10% annual return, and choose a 40% annuity purchase at retirement.

Monthly contribution: ₹5,000
Investment duration: 30 years (360 months)
Expected return: 10% p.a.
Total invested: ₹18,00,000
Projected NPS corpus: ₹1,13,96,627
Lump sum (60% allocation): ₹68,37,976
Annuity corpus (40% allocation): ₹45,58,651
Estimated monthly pension: ₹22,793

A total contribution of ₹18 lakh grows to a projected corpus of ₹1,13,96,627. With a 40% annuity allocation, ₹68,37,976 is modeled as lump sum and ₹45,58,651 is used for annuity purchase. Since December 2025, non-government subscribers above ₹12 lakh must annuitise only 20%, but only 60% of the corpus is tax-free on exit.

This calculator is scoped to non-government NPS Tier I exits. For premature exit before 60, it applies the 80% annuity floor when corpus exceeds ₹5 lakh. For normal exit at age 60+, it allows full withdrawal up to ₹8 lakh and applies a 20% annuity floor above ₹12 lakh. The ₹8-12 lakh normal-exit band is shown as a simplified illustration because current rules can route the non-lump-sum balance to annuity or systematic/phased withdrawal.

NPS returns are market-linked. Equity, corporate bond, and government bond allocations can produce very different long-term outcomes.
Exit rules matter. The calculator is scoped to non-government Tier I assumptions and simplifies certain regulatory bands for planning clarity.
Annuity income is not the same as corpus growth. The calculator uses a 6% annuity yield assumption, while actual monthly pension depends on the annuity provider and plan selected.
Tax treatment is separate from corpus projection. NPS offers deductions under sections such as 80CCD, but annuity income is generally taxable in the year received.
PFRDA's December 2025 exit rules let non-government subscribers take up to 80% as lump sum, yet Section 10(12A) still exempts only 60% of the corpus. Any lump sum beyond 60% is taxed at your slab rate in the year of exit.
Inflation reduces purchasing power. A corpus above ₹1 crore at retirement may still need to be tested against future household expenses.
