The National Pension System (NPS) is a government-regulated retirement savings scheme in India, open to all Indian citizens between the ages of 18 and 70. Both salaried employees (Government and Non-Government) and self-employed individuals can open an NPS account. It is managed by the Pension Fund Regulatory and Development Authority (PFRDA).
Enter your current age, target retirement age, monthly contribution amount, expected annual return, and annuity preferences. The calculator compounds your contributions monthly over your investment horizon to estimate the total corpus. It then splits the corpus into a lump sum withdrawal and an annuity portion to show your estimated monthly pension.
The calculator uses the Future Value of a growing annuity formula. Each year's monthly contributions are compounded at your chosen return rate. If you select an annual step-up, each year's contributions increase by that percentage. The final corpus equals the sum of all compounded contributions over your investment period.
At maturity (retirement), you can withdraw up to 60% of your NPS corpus as a tax-free lump sum. The remaining 40% (minimum) must be used to purchase an annuity plan from a PFRDA-empanelled insurer, which then provides you a regular monthly pension. You can choose to annuitise more than 40% if you prefer a higher pension.
The monthly pension is estimated by dividing the annuity corpus by 12 and applying the expected annuity rate. For example, if your annuity corpus is ₹40 lakhs and the annuity rate is 6% p.a., your estimated monthly pension would be approximately ₹40,00,000 × 6% ÷ 12 = ₹20,000 per month.
NPS offers tax deductions under Section 80CCD(1) up to ₹1.5 lakh (within the 80C limit), plus an additional ₹50,000 exclusively under Section 80CCD(1B). Employer contributions get a separate deduction under 80CCD(2). The lump sum withdrawal of up to 60% at retirement is completely tax-free.
For Tier-I (mandatory pension account), the minimum annual contribution is ₹1,000, which works out to about ₹500 per month. However, to build a meaningful retirement corpus, financial advisors typically suggest investing at least ₹3,000–₹5,000 per month, especially if you start in your 30s or later.
Yes, and it is highly recommended. The annual contribution step-up feature in this calculator lets you model that increase. Even a 5–10% annual increase in contributions, aligned with your salary growth, can significantly boost your final corpus due to the compounding effect over a long investment horizon.
