NPS Calculator
Estimate your National Pension System (NPS) corpus and monthly pension.
Assumptions used in this calculation
- Minimum annuitization: PFRDA rules require at least 40% of the NPS corpus to be used to purchase an annuity at retirement.India · Pension Fund Regulatory and Development Authority (PFRDA), Government of India
- Annuity rate: The monthly pension is an estimate based on your assumed annuity payout rate, not a specific provider's quote.India
About this calculator
NPS is unlike most other retirement products in that its payout at retirement isn't a single number, the corpus you build up gets split between a lump sum you can withdraw and a portion that's mandatorily locked into an annuity for life, and only the annuitized part actually converts into a monthly pension, so estimating your eventual income requires two separate calculations chained together. This calculator first projects your NPS corpus from monthly contributions and expected annual returns using the standard SIP future-value formula, then splits the result into the tax-free lump-sum withdrawal (up to 60%) and the mandatory annuity portion (at least 40%), converting that annuity share into an estimated monthly pension at an annuity payout rate you can adjust. That gives you both halves of the retirement picture, a lump sum in hand and an ongoing pension, rather than a single corpus figure that doesn't tell you what your actual monthly income in retirement will look like.
Worked example
₹5,000/month, 10% expected return, 20 years, 40% annuitized at 6%
Result: Corpus ≈ ₹38.3 lakh; estimated monthly pension ≈ ₹7,657
