The National Pension System (NPS) has increasingly become one of the most preferred retirement planning options for working professionals in India. Designed for long-term wealth creation, NPS offers low management costs and the flexibility to invest more aggressively in equity compared to traditional pension schemes. With growing awareness around retirement planning, many investors now see NPS as a long-term wealth builder rather than just a pension tool. But the most common question remains — if someone contributes ₹1 lakh every month, how much pension can they actually receive at retirement?
Before calculating returns, it is important to understand how NPS works. Investors contribute a fixed amount regularly, and the money is invested in market-linked instruments such as equity, government securities, and corporate debt. The power of compounding plays a major role in determining the final retirement corpus, and therefore, starting early makes a massive difference.
In NPS, the amount you invest is important — but when you begin investing is even more crucial. Since NPS is designed for long-term growth, early contributions enjoy more compounding cycles. For example, someone starting at age 30 will have nearly twice the pension benefit compared to someone who starts at 40, even with the same monthly contribution.
A late start means fewer compounding years, resulting in a smaller retirement corpus and significantly lower monthly pension. This is why investment advisors strongly recommend beginning NPS contributions as early as possible.
Let us assume an investor starts at age 30 and contributes ₹1,00,000 per month. If we estimate an average return of 10% annually, then over 30 years:
| Age of Start | Investment Period | Total Contribution | Total Value at Age 60 |
|---|---|---|---|
| 30 years | 30 years | ₹3.6 crore | ₹20.69 crore |
At retirement, an NPS subscriber can withdraw 60% of the total corpus tax-free, while the remaining 40% must be used to purchase an annuity.
| Particulars | Amount |
|---|---|
| Total Corpus at 60 | ₹20.69 crore |
| Lump Sum Withdrawal (60%) | ₹12.41 crore (Tax-free) |
| Amount Used for Annuity (40%) | ₹8.28 crore |
Assuming a 6% annuity rate, the investor will receive approximately:
Suppose the average return increases from 10% to 12% annually, then the same investment would grow to:
| Estimated Return | Corpus at Age 60 | Approx. Monthly Pension |
|---|---|---|
| 12% | ₹30.64 crore | ~₹6.12 lakh |
This clearly shows how long-term equity exposure in NPS can boost retirement income substantially.
Here’s how pension changes if investment begins later but with the same monthly contribution of ₹1,00,000:
| Starting Age | Tenure | Corpus at 60 | Approx Monthly Pension |
|---|---|---|---|
| 30 years | 30 years | ₹20.69 crore | ~₹4.13 lakh |
| 40 years | 20 years | ₹7.2 crore | ~₹1.44 lakh |
| 50 years | 10 years | ₹2 crore | ~₹40,000 |
A difference of just 10 years in starting age can reduce the pension by more than half — proving why early entry is the smartest strategy.

Investing ₹1 lakh per month in NPS can provide a pension ranging from ₹40,000 to over ₹6 lakh per month, depending on the age of entry and market returns. The earlier you start, the larger your retirement wealth and monthly pension will be. For young professionals, especially those in their late 20s and early 30s, NPS stands out as a powerful, tax-efficient retirement instrument with long-term compounding benefits.
