Corpus Projection
The model compounds the opening corpus monthly, then adds that month’s employee and employer contributions. At the end of each 12-month period, the contribution is increased by the selected step-up percentage.
Corpus = Previous corpus × (1 + annual return ÷ 12) + monthly contributionLump Sum & Pension
The selected annuity percentage is applied to the projected corpus. The form automatically raises the minimum annuity share for a premature exit: 80% for a government exit before age 60, and 80% for a non-government exit before its applicable normal-exit point. All Citizen normal exit is reached at age 60 or after 15 years of subscription, whichever is earlier.
For a normal Government or Non-Government exit, the calculator applies the option to withdraw 100% when projected pension wealth does not exceed ₹8 lakh. For a premature Government resignation or removal, or a premature Non-Government voluntary exit, it applies the full-withdrawal option up to ₹5 lakh. Above those thresholds, normal Government exit uses at least 40% annuity, normal Non-Government exit uses at least 20%, and premature exit uses at least 80%.
For NPS Vatsalya exit after majority and fresh KYC, the calculator permits 100% lump-sum withdrawal when the projected corpus is below ₹8 lakh. At ₹8 lakh or more, it enforces at least 20% for annuity and allows up to 80% as lump sum. A subscriber choosing an annuity below the threshold must still allocate at least 20%; selecting 0% represents the separate full-withdrawal option.
Death, disability, joining after age 60, and other special-exit options can differ and require an individual review.
Monthly pension = Annuity corpus × annuity rate ÷ 12UPS Payout
The assured payout is one-half of the last 12-month average Basic Pay multiplied by qualifying-service months divided by 300. Service is capped at 300 months for this formula; UPS payout does not apply below 120 months, and the pre-adjustment minimum is ₹10,000 from 120 months.
Admissible payout = Assured payout × min(IC ÷ BC, 1) × (1 − final withdrawal %)Final withdrawal is calculated from the lower of Individual Corpus and Benchmark Corpus. The separate statutory lump sum is one-tenth of last-drawn Basic Pay plus DA for each completed 6 months of qualifying service. Dearness Relief and the 60% family payout are shown separately.
Projection mode assumes timely contributions, no partial withdrawals and equivalent returns for Individual and Benchmark Corpus. Exact mode accepts the CRA values that determine any corpus shortfall. The Government NPS comparison uses 10% employee and 14% government contributions; UPS Individual Corpus uses matching 10% contributions.
NPS Tax Benefit
The tax calculator first determines the statutory NPS deduction under Section 123, Schedule XV and Section 124 of the Income-tax Act, 2025. It then compares ordinary income tax before and after the usable NPS deduction under the selected regime.
Estimated tax reduction = Tax before usable NPS deduction − Tax after usable NPS deductionThe calculation includes the applicable ordinary-income slabs, resident rebate and marginal relief, surcharge and marginal relief, 4% health and education cess, and rounding for Tax Year 2026–27. It does not calculate special-rate income such as capital gains, lottery income or virtual digital assets.
The separate exit-tax panel does not estimate “tax saved.” It identifies the projected NPS closure-payment exemption capped at 60% of corpus and any projected lump sum above that cap.
Known Limitations
- Returns, salary growth, DA/DR growth, life expectancy and annuity rates are assumptions, not promises.
- The NPS tax-benefit calculator supports Tax Year 2026–27 and ordinary slab-rate income only; it is not an ITR preparation tool or tax-regime recommendation.
- Charges, pay-commission resets and transaction timing are not modelled.
- UPS projection mode covers ordinary superannuation; voluntary retirement, FR 56(j), resignation, dismissal, disability, death and legacy top-up cases require individual review.
- Qualifying service and pay are certified by the Head of Office; CRA corpus values and the PAO-authorised UPS Payout Order control actual benefits.
- The age-60 government test is a planning proxy; the applicable service-rule retirement or superannuation event controls an actual NPS exit.
- Corporate normal exit depends on retirement or superannuation under the applicable employment terms.
- Rules can change after the displayed source verification date.
NPS vs Mutual Fund Comparison
The comparison starts each projection with its own opening value, then applies the same monthly investment and annual step-up. Separate NPS and mutual fund return assumptions are converted to monthly rates. The displayed difference is the NPS corpus minus the mutual fund corpus at the selected age.
Each corpus = Previous corpus × (1 + selected annual return ÷ 12) + shared monthly investmentThe NPS side then applies the All Citizen normal or premature exit rule using the selected ages and completed subscription years. The mutual fund side stays as a gross corpus; the calculator does not invent a redemption schedule or systematic withdrawal plan.
Both corpus results remain before personal tax and do not deduct product charges, expense ratios, exit loads or transaction costs. The comparison shows a high-level written summary of current NPS and mutual fund tax treatment rather than estimating personal tax saved. Use the dedicated NPS tax calculator for a contribution-side estimate.
NPS vs PPF Comparison
The comparison starts each account with its own opening value and applies the same monthly deposit and annual increase to both. The deposit used for each account is capped at ₹12,500 per month so the projected annual contribution remains within the PPF statutory limit of ₹1.5 lakh.
NPS month = Previous corpus × (1 + assumed return ÷ 12) + depositPPF year-end balance = Opening balance + deposits + monthly accrued interestThe NPS projection uses monthly compounding and applies the All Citizen exit allocation at the comparison age. For PPF, each monthly deposit is assumed to clear by the fifth, interest accrues monthly on the eligible balance, and accrued interest is added annually. The selected PPF interest rate is held constant even though notified rates can change.
A projection longer than 15 years assumes the PPF account is validly extended with contributions in 5-year blocks. The model does not include financial-year alignment, PPF loans, withdrawals, premature closure, penalties, NPS charges or personal taxes.
