NPS Calculator – National Pension Scheme Corpus & Pension Estimator

The National Pension System (NPS) is a government-sponsored voluntary retirement savings scheme launched in 2004. It is regulated by the Pension Fund Regulatory and Development Authority (PFRDA). NPS is open to all Indian citizens aged 18–65 and allows them to contribute regularly during their working life to build a retirement corpus. On maturity at age 60, subscribers can withdraw up to 60% as a lump sum (tax-free) and must use at least 40% to purchase an annuity for a monthly pension.

The NPS corpus is calculated using the Future Value of an annuity formula: Corpus = PMT × [((1 + r)^n − 1) / r] × (1 + r), where PMT is the monthly contribution, r is the monthly rate of return (annual rate ÷ 12 ÷ 100), and n is the total number of months until retirement (age 60). The corpus grows based on the returns generated by the chosen pension fund and asset allocation (equity, corporate bonds, government securities).

At maturity, NPS subscribers must mandatorily use at least 40% of the accumulated corpus to purchase an annuity from a PFRDA-approved life insurance company. The remaining 60% can be withdrawn as a lump sum, which is fully exempt from income tax. If the total corpus is less than ₹5 lakh, the entire amount can be withdrawn as a lump sum.

NPS offers three layers of tax benefits: 1) Deduction of up to ₹1.5 lakh under Section 80CCD(1) within the overall 80C limit; 2) An additional exclusive deduction of up to ₹50,000 under Section 80CCD(1B) over and above the 80C limit; 3) Employer contributions up to 10% of salary (Basic + DA) are deductible under Section 80CCD(2). The 60% lump sum withdrawal at maturity is also tax-free.

NPS has two account types: Tier I is the mandatory pension account with lock-in till age 60. Partial withdrawals are allowed after 3 years for specific purposes (education, medical emergency, home purchase). Tier II is a voluntary savings account with no lock-in, allowing free withdrawals anytime. However, Tier II does not offer tax benefits except for government employees investing under certain conditions.

Under Active Choice, subscribers manually decide the asset allocation across equity (max 75%), corporate bonds, government securities, and alternative assets. Under Auto Choice (Lifecycle Fund), the allocation automatically shifts from higher equity to lower equity as you age. For young investors with higher risk appetite, Active Choice with maximum equity allocation typically generates better long-term returns. Conservative investors or those nearing retirement may prefer Auto Choice.

Premature exit from NPS (before age 60) is allowed after 3 years of subscription. However, in this case, only 20% of the corpus can be withdrawn as a lump sum (taxable), and the remaining 80% must be used to buy an annuity. This is less favorable than the standard 60% lump sum at age 60. In case of the subscriber's death, the entire corpus is paid to the nominee.
