NPS Calculator
Project your National Pension System corpus, contribution growth, lump sum, annuity amount, monthly pension, tax benefits and inflation-adjusted retirement value.
Last Updated: July 22, 2026Calculate NPS Corpus and Pension
Use realistic return and cost assumptions. NPS returns are market-linked, and annuity rates are insurer quotations rather than guaranteed investment returns.
Current rule: Normal exit for All Citizen or Corporate NPS generally permits up to 80% lump sum and requires at least 20% annuity.

This projection assumes monthly contributions at month-end, a constant net return after the entered cost drag, and one annual step-up. Actual NPS NAVs, contribution dates, charges, asset allocation and annuity quotations will change the result.
What Is an NPS Calculator?
An NPS calculator projects how an existing Tier I balance and future contributions may grow before retirement. It also splits the projected National Pension System corpus into a lump-sum portion and an annuity purchase amount, then estimates the monthly pension from the entered annuity rate.
NPS is market-linked. Your final corpus depends on contribution timing, contribution increases, pension fund performance, asset allocation, charges and the number of years invested. The result is a scenario, not a promised maturity value. The year-wise table helps you see whether growth comes mainly from your deposits or from long-term compounding.
This calculator applies the current sector-aware exit framework. Under the updated PFRDA All Citizen Model guidance, an eligible non-government subscriber at normal exit may generally take up to 80% as lump sum and allocate at least 20% to annuity. Government-sector normal exit retains a minimum 40% annuity allocation. Premature exit normally requires at least 80% annuity, subject to small-corpus alternatives.
How to Use the NPS Calculator
- Select your NPS sector and planned exit type.
- Enter your current age and the age when you expect to stop contributing.
- Add your existing Tier I corpus, personal monthly contribution and employer contribution.
- Enter an annual contribution increase. Use zero if your contribution will remain level.
- Choose an expected portfolio return and a cost-drag assumption. Avoid treating recent returns as a guarantee.
- Set the annuity allocation. The calculator enforces the standard minimum where a small-corpus exception does not apply.
- Add an annuity rate, inflation, tax regime, Basic plus DA and marginal tax rate.
- Compare projected corpus, invested amount, growth, real value, exit split, pension and annual tax estimate.
NPS Calculation Formula
The tool compounds the opening balance monthly and adds each month's personal and employer contributions at month-end. At the start of each projection year, both monthly contributions increase by the entered step-up percentage.
Monthly projection
Closing balance = Opening balance × (1 + monthly net return) + monthly contributions
Monthly net return is derived from the annual expected return minus the entered annual cost drag. The monthly pension estimate is annuity purchase amount × annuity rate ÷ 12.
For example, assume age 30, retirement at 60, an existing corpus of ₹5 lakh, ₹10,000 personal and ₹5,000 employer monthly contributions, 10% annual step-up, 9.5% expected return and 0.1% cost drag. The calculator processes 360 monthly periods. Changing the return by one percentage point or removing the step-up produces a large difference because the assumptions operate for 30 years.
Current NPS Exit Rules in 2026
| Exit situation | Maximum lump sum | Minimum annuity | Small-corpus treatment |
|---|---|---|---|
| All Citizen or Corporate, normal exit | Up to 80% | 20% | Up to ₹8 lakh: full payout, SLW, SUR or another approved option. Above ₹8 lakh to ₹12 lakh: up to ₹6 lakh lump sum, with the balance through SUR or annuity. |
| Government sector, normal exit | Up to 60% | 40% | Applicable options depend on current government-sector regulations and subscriber records. |
| Premature exit | Up to 20% | 80% | Up to ₹5 lakh: full payout, SLW, SUR or another approved option may be available. |
| Death of subscriber | Up to 100% | Not modeled | Nominee or legal-heir options depend on sector and current rules. |
SLW means Systematic Lump Sum Withdrawal. SUR means Systematic Unit Redemption. This calculator models only a simple lump sum and annuity split. It does not project a systematic redemption schedule. Exit permission and income-tax exemption are separate rules, so an 80% permitted lump sum is not automatically 80% tax-free.
NPS Investment Choices and Expected Return
NPS Tier I offers Equity, Corporate Debt, Government Securities and, where available, Alternative Assets. Under common Active Choice, Equity exposure is generally capped at 75%, while Corporate Debt and Government Securities may reach 100% and Alternative Assets have a smaller cap. Auto Choice changes the allocation with age. New Multiple Scheme Framework options may use different risk limits and lock-in conditions.
Do not select the expected return from the product label alone. Review your actual scheme, asset mix and pension fund performance. A growth-oriented allocation may support a higher long-term assumption but also creates larger short-term declines. A debt-heavy allocation may reduce volatility while producing a different expected return.
- Use a conservative return for essential retirement planning.
- Run at least three scenarios, such as 7%, 9% and 11%.
- Increase the cost-drag input if your combined charges are higher.
- Review the projection each year using your current CRA balance.
NPS Tax Benefits and Exit Tax
The calculator estimates the additional ₹50,000 deduction under Section 80CCD(1B) only when the old tax regime is selected. That amount must not also be claimed under Section 80CCD(1). It does not estimate unused room within the shared ₹1.5 lakh Section 80C, 80CCC and 80CCD(1) limit.
Employer contributions may qualify separately under Section 80CCD(2). The entered employer amount is capped at 14% of salary for Central or State Government employees, 14% for other employees under the new regime, and 10% for other employees under the old regime. Salary for this simplified cap uses the entered monthly Basic plus DA. Confirm payroll treatment and the statutory salary definition before filing.
Current income-tax guidance generally exempts up to 60% of the corpus on eligible closure under Section 10(12A). Annuity pension is generally taxable when received. Because non-government exit rules now permit up to 80% lump sum, this tool flags any lump sum above 60% of the total corpus as potentially taxable. It does not make a final tax determination.
Inflation and Retirement Income
A future corpus looks larger because it is measured in future rupees. The inflation-adjusted corpus discounts the projected amount back to today's purchasing power. At 6% inflation, ₹1 crore received 30 years from now has purchasing power of about ₹17.4 lakh in today's money.
The pension estimate has the same issue. A fixed annuity starting after 30 years must be compared with future expenses, not current expenses. The calculator therefore shows the starting pension in today's money. An annuity with spouse protection, return of purchase price or annual increases may quote a different starting rate from the simple assumption entered here.
How to Improve Your NPS Corpus
- Start early. More years give contributions more time to compound.
- Use an annual step-up linked to salary growth instead of keeping deposits flat.
- Include employer contributions when available and verify the amount in your statement.
- Choose an asset allocation you understand and review it as retirement approaches.
- Avoid judging long-term returns from one strong or weak year.
- Compare annuity options and current ASP quotations before retirement.
- Keep an emergency fund outside NPS because Tier I withdrawals follow scheme rules.
Limitations of This NPS Calculator
The projection uses a constant net annual return and a fixed annual step-up. It excludes daily NAV movement, irregular deposits, contribution delays, asset switches, partial withdrawals, scheme-specific MSF conditions, CRA and PoP transaction charges, GST, tax on investment income, and changes to pension or tax law.
The tool does not model SLW, SUR, deferment, death benefits, nomination, a detailed annuity contract, spouse age, return of purchase price, increasing pension or live ASP rates. The tax estimate excludes cess, surcharge, rebate, deductions, the aggregate employer-benefit limit and interaction with other income. Use your CRA statement, employer records, PFRDA rules and tax documents for an actual decision.

Frequently Asked Questions
How is the NPS corpus calculated?
The calculator compounds the existing balance monthly, adds personal and employer contributions at month-end, and applies the annual contribution step-up once per projection year. It subtracts the entered cost drag from the expected annual return.
What return should I use in an NPS calculator?
Use a conservative long-term assumption suited to your actual asset allocation. Test several rates because NPS returns are market-linked and no return is guaranteed.
What is the minimum NPS annuity percentage in 2026?
At normal exit, the minimum is generally 20% for eligible All Citizen and Corporate subscribers and 40% for Government-sector subscribers. Premature exit normally requires at least 80% annuity. Small-corpus alternatives may apply.
Can I withdraw 80% of NPS as a lump sum?
An eligible non-government subscriber at normal exit may generally withdraw up to 80% under current PFRDA rules. Income-tax guidance generally exempts only up to 60% of total corpus on eligible closure, so withdrawal permission and tax exemption must be reviewed separately.
Is NPS pension tax-free?
No. The annuity purchase amount is not taxed when transferred to the annuity provider, but pension payments are generally taxable as income when received.
Does the NPS calculator include employer contributions?
Yes. Enter the monthly employer contribution separately. The calculator grows it with the same annual step-up and estimates its current-year Section 80CCD(2) deduction subject to the selected cap.
Is the ₹50,000 NPS deduction available in the new tax regime?
The calculator shows the Section 80CCD(1B) personal-contribution deduction only for the old regime. Employer contribution under Section 80CCD(2) may qualify under both regimes, subject to the applicable salary percentage and other conditions.
What happens if my NPS corpus is below ₹8 lakh?
For an eligible non-government normal exit, current rules permit a full payout, SLW, SUR or another approved option when the corpus is up to ₹8 lakh. Premature exit has a separate ₹5 lakh small-corpus threshold.
How accurate is this NPS calculator?
The arithmetic follows the inputs and stated monthly method. Actual results differ because NAV returns, deposits, charges, exit eligibility, tax law and annuity quotations change over time.
