NPS Calculator

What is NPS Calculator?

An NPS calculator is an online tool that helps you estimate your National Pension System corpus, annuity allocation, lump sum payout, and expected pension based on contribution amount, current age, retirement age, and expected return.

How NPS Calculator Works

The calculator uses your current age, retirement age, existing NPS balance, contribution frequency, yearly or monthly investment amount, and expected annual return to project your retirement corpus. It then estimates the mandatory annuity portion, available lump sum, and indicative pension income at retirement.

Formula

The NPS calculator uses the standard future value of investments formula:

M = P × [((1 + i)ⁿ - 1) / i] + Existing Balance × (1 + i)ⁿ

Where:

• P = Contribution per period
• i = Rate of return per contribution period
• n = Total number of contribution periods
• M = Estimated retirement corpus

The calculator handles monthly or yearly contribution frequency internally before estimating annuity, lump sum, and pension values.
