NPS Calculator

What it computes

You give your current age, a yearly contribution and an expected annual return. The tool assumes you contribute until age 60 and calculates the corpus as contribution × ((1 + r)^years − 1) / r, which treats each contribution as made at the end of its year. It then splits the corpus 60% lump sum and 40% annuity.

Worked example

A 30-year-old contributing Rs. 50,000 a year at 10% for 30 years reaches about Rs. 82.2 lakh. The 60% lump sum is about Rs. 49.3 lakh and the 40% annuity purchase about Rs. 32.9 lakh.

Things the estimate leaves out

• The 60/40 split is a simplification. The rules on how much of the corpus must buy an annuity and how much can be withdrawn have changed, so check the current PFRDA rules for your account type.
• It does not estimate the monthly pension from the annuity, because that depends on the annuity provider's rate.
• Returns are a single constant rate. NPS returns depend on your equity, corporate bond and government bond allocation and vary yearly.
• If your age is 60 or more, the number of years is zero or negative and the result will not be meaningful.
• Tax benefits (such as the extra deduction for NPS under the old regime) are not part of this calculation.
