What Is an NPS Calculator?

An NPS calculator estimates the retirement corpus that may accumulate in your National Pension System account. It considers your current age, planned retirement age, monthly contribution, existing corpus, annual investment increase and expected return.

The calculator also divides your projected retirement corpus into an estimated lump-sum amount and an annuity amount. It then uses the selected annuity rate to estimate your annual and monthly pension.

Retirement Corpus Estimate your possible NPS account value at retirement.
Lump-Sum Estimate Calculate the amount remaining after annuity allocation.
Pension Projection Estimate monthly pension using your assumed annuity rate.

How Does the NPS Calculator Work?

The calculator converts the expected annual investment return into an equivalent monthly rate. It adds your monthly contribution to the NPS corpus and applies the estimated return every month until your selected retirement age.

Equivalent monthly return:
(1 + Annual Return ÷ 100)1/12 − 1

Estimated monthly closing corpus:
(Opening Corpus + Monthly Contribution) × (1 + Monthly Return)

When an annual investment increase is entered, the calculator raises your monthly contribution after every completed investment year. This helps show how gradually increasing your contributions may affect the final retirement corpus.

How Is the Estimated Pension Calculated?

The selected annuity percentage is applied to the estimated retirement corpus. The annuity amount is then multiplied by the expected annual annuity rate.

Annuity amount:
Retirement Corpus × Annuity Percentage

Estimated annual pension:
Annuity Amount × Expected Annuity Rate

Estimated monthly pension:
Estimated Annual Pension ÷ 12

The actual pension can vary according to the annuity provider, annuity plan, prevailing rates, subscriber age and other terms applicable when the annuity is purchased.

Why Increase Your NPS Contribution Every Year?

A yearly contribution increase can help your retirement savings grow with your income. Even a small annual increase may make a significant difference over a long investment period because the additional contributions receive more time to generate returns.

This tool provides an illustrative mathematical projection and does not guarantee any investment return, retirement corpus, lump-sum withdrawal or pension amount. Confirm current NPS rules, charges and tax treatment through an authorised source or qualified financial professional.
