NPS Calculator
Estimate your National Pension System corpus, the annuity you must buy and the monthly pension it pays.
Inputs
Formula
- FV = P × ((1+i)^n − 1) / i × (1+i)
- Pension = corpus × annuity share × annuity rate / 12
NPS invests your monthly contribution in market-linked funds until retirement. At exit you must use at least 40% of the corpus to buy an annuity that pays a lifelong pension; the rest can be withdrawn tax-free. This tool shows all three numbers so you can see whether the pension is enough.
