The National Pension System (NPS) is a government-backed retirement scheme that helps individuals build a pension corpus through long-term investments. Since returns are market-linked, understanding how to calculate NPS maturity is important for effective retirement planning.
In this guide, we explain the NPS calculation formula, how maturity is divided into lump sum and annuity, and provide simple examples. We also show why using an NPS Calculator online is the easiest way to estimate your pension.
Overview of NPS Calculation
| Factor | Details |
|---|---|
| Minimum Contribution | ₹1,000 per year |
| Investment Tenure | Till age 60 (extendable up to 70 years) |
| Expected Return Rate | Market-linked (average 8%–10% annually) |
| Maturity Split | 60% lump sum withdrawal + 40% compulsory annuity |
| Tax Benefits | Section 80C (₹1.5 lakh) + 80CCD(1B) (extra ₹50,000) |
| Lock-in Period | Till retirement; partial withdrawals allowed |
How to Calculate NPS Maturity?
The NPS maturity amount depends on four factors:
- Contribution Amount (monthly or yearly)
- Expected Rate of Return from chosen asset allocation
- Investment Tenure (years left till retirement)
- Annuity Purchase (minimum 40% must be used for annuity)
The basic formula used to calculate NPS is similar to compound interest:
Future Value (FV) = P × [((1 + r)n – 1) ÷ r] × (1 + r)
- P = Monthly contribution
- r = Expected monthly return rate
- n = Total number of months invested
Examples of NPS Calculation
Case 1: ₹5,000 per month for 30 years
Contribution: ₹5,000/month
Tenure: 30 years (360 months)
Expected Return: 9%
Maturity Value ≈ ₹1.0 – 1.1 crore
60% Lump Sum = ₹60–65 lakh
40% Annuity = ₹40–45 lakh (monthly pension depends on annuity rate)
Case 2: ₹10,000 per month for 25 years
Contribution: ₹10,000/month
Tenure: 25 years (300 months)
Expected Return: 9%
Maturity Value ≈ ₹95 lakh – 1 crore
60% Lump Sum = ~₹57 lakh
40% Annuity = ~₹38 lakh
Case 3: ₹3,000 per month for 20 years
Contribution: ₹3,000/month
Tenure: 20 years (240 months)
Expected Return: 8%
Maturity Value ≈ ₹17–18 lakh
60% Lump Sum = ~₹10–11 lakh
40% Annuity = ~₹7 lakh
NPS Maturity Comparison Table
Here is a comparison of estimated NPS maturity values for different contributions and investment tenures (assuming 9% annual returns):
| Monthly Contribution | 20 Years | 25 Years | 30 Years |
|---|---|---|---|
| ₹3,000 | ~₹18 lakh | ~₹35 lakh | ~₹60 lakh |
| ₹5,000 | ~₹30 lakh | ~₹58 lakh | ~₹1.0 crore |
| ₹10,000 | ~₹60 lakh | ~₹1.15 crore | ~₹2.0 crore |
Final maturity will be split into 60% lump sum (tax-free) and 40% annuity (taxable).

NPS maturity is calculated using compound interest on monthly contributions, tenure, and returns. At retirement, 60% can be withdrawn and 40% must go into annuity.
Q2. How much pension will I get from NPS?
The pension depends on the annuity amount (40% of corpus) and annuity rate offered by insurers at retirement.

Yes, 60% of maturity is tax-free. The 40% annuity portion is taxable as per income tax slab.
Q5. Can I exit NPS before 60?
Yes, but only 20% can be withdrawn lump sum; 80% must be invested in annuity.
Q6. How much will I get if I invest ₹5,000 per month in NPS?
For 30 years at 9% returns, you may build a corpus of ~₹1 crore, with ₹60 lakh lump sum and ₹40 lakh annuity.
