NPS CalculatorRetirement estimates, explained

Open Methodology

Every estimate should be explainable.

Our calculators use straightforward projection formulas and keep regulatory rules separate from assumptions you can change.

01

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 contribution
02

Lump 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.

Normal government exit uses at least 40% annuity; normal non-government exit uses at least 20%. Small-corpus, death, disability and other special-exit options can differ and are identified as exceptions rather than inferred by the calculator.

Monthly pension = Annuity corpus × annuity rate ÷ 12
03

UPS Payout

UPS is not calculated as an annuity from a projected corpus. The full-service assured payout starts from 50% of the last 12-month average basic pay and is proportionate for eligible service below 25 years. Corpus sufficiency and final withdrawal can reduce the admissible payout.

04

Known Limitations

  • Returns and annuity rates are assumptions, not promises.
  • Charges, taxes, and transaction timing are not deducted.
  • The age-60 government test is a planning proxy; the applicable service-rule retirement or superannuation event controls an actual exit.
  • Corporate normal exit depends on retirement or superannuation under the applicable employment terms.
  • Small-corpus, death, disability and other special-exit options require individual review.
  • Inflation-adjusted values are estimates based on a constant rate.
  • Rules can change after the displayed source verification date.
