NPS retirement corpus, tax-free lumpsum and monthly pension estimate.. NPS Calculator is a free online tool from the ToolsRift Finance & Health Calculators collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Enter your monthly contribution, expected return, current age and annuity rate. The calculator shows the corpus, tax-free lumpsum and monthly pension.
Monthly contributions compound at your expected return until retirement using the annuity future-value formula, building the total corpus available at age 60.
At maturity you can withdraw up to 60% of the corpus tax-free as a lumpsum; the remaining 40% must buy an annuity that pays your monthly pension.
The annuity portion is multiplied by an assumed annuity rate to estimate monthly pension. Actual pension depends on the annuity plan and prevailing rates.
