Pension Calculator: How much do you need to invest in NPS for a monthly pension of ₹30,000? Understand the full calculation..

Pension Calculator: Receiving a monthly pension of ₹30,000 after retirement can make managing expenses much easier. But how much money needs to be invested in the NPS to achieve this? The answer depends on your age, the returns earned on the investment, and the annuity rate applicable at the time of retirement.

Let’s understand this with a simple example. Suppose you wish to exit the NPS at the age of 60. At the time of retirement, 40% of your NPS corpus is allocated towards purchasing an annuity.

How much corpus is required for a pension of ₹30,000?

First, let's look at the pension calculation. A monthly pension of ₹30,000 translates to an annual pension of ₹3.60 lakh. Now, assume the annuity rate at the time of retirement is 6% per annum. Based on this, an annuity corpus of approximately ₹60 lakh is required to generate an annual pension of ₹3.60 lakh.

Next, consider the standard NPS withdrawal rules. At least 40% of the corpus must be invested in an annuity. Therefore, to secure an annuity corpus of ₹60 lakh, the total NPS corpus needs to be around ₹1.50 crore.

Out of this, approximately ₹60 lakh would go towards purchasing the annuity. The remaining amount—about ₹90 lakh, or 60% of the total—can be withdrawn as a lump sum. According to current PFRDA regulations, a minimum of 40% of the corpus is utilized for the annuity upon standard withdrawal, while up to 60% can be withdrawn as a lump sum.

How can a corpus of ₹1.50 crore be built?

Now, the real question is: how do you build a corpus of ₹1.50 crore? Your age plays a crucial role here. Let’s assume an average annual return of 10% on your NPS investment. You invest monthly and continue doing so until you reach the age of 60. Based on this, the estimated monthly investment required to start NPS at different ages could look like this:

Age at start    Time until age 60    Estimated monthly investment
25 years    35 years                        Approx. ₹1,000
30 years    30 years                       Approx. ₹1,700
35 years    25 years                       Approx. ₹2,800
40 years    20 years                      Approx. ₹4,900
45 years    15 years                        Approx. ₹9,000
50 years    10 years                       Approx. ₹18,300

**Starting at age 30**

If you are 30 years old and start investing approximately ₹1,700 per month in NPS, you have a 30-year horizon until age 60. Assuming an average annual return of 10%, this investment could grow to a corpus of approximately ₹1.50 crore.

Now, 40% of this corpus—i.e., around ₹60 lakh—would be invested in an annuity. If the annuity rate is 6% at that time, it could generate an annual pension of approximately ₹3.60 lakh, which translates to a monthly pension of about ₹30,000.

**Starting at age 40**

If you start investing in NPS at age 40, only 20 years remain until age 60. To aim for the same corpus of ₹1.50 crore, assuming a 10% average return, you would need to invest approximately ₹4,900 per month.

This means that starting 10 years later—compared to starting at age 30—significantly increases the required monthly investment. This is due to the power of compounding.

**How ​​much to invest at age 50?**

If you start NPS at age 50, only 10 years remain until age 60. In this scenario, to build a corpus of ₹1.50 crore, one would need to invest approximately ₹18,300 per month based on these projections.

In other words, the later one starts preparing for retirement, the higher the monthly investment required.

60% of the amount can be withdrawn as a lump sum.

In this example, which assumes a monthly pension of ₹30,000, we have considered a total corpus of ₹1.50 crore. If 40% of the corpus (i.e., ₹60 lakh) is allocated to an annuity at the time of withdrawal, the remaining 60% (i.e., approximately ₹90 lakh) can be withdrawn as a lump sum.

According to the PFRDA, account holders have the option to continue with the NPS even after turning 60. The account can be maintained until the age of 75. Under certain circumstances, the withdrawal of the lump sum and the purchase of the annuity can also be deferred to a later date.
