NPS Calculator

What this tool does

The NPS Calculator projects National Pension System contributions month by month until retirement, with an optional yearly increase. It splits the corpus between the lump sum and the annuity purchase according to the minimum annuity rule for your subscriber type and estimates the resulting monthly pension.

The National Pension System is a market-linked retirement scheme regulated by PFRDA. Your contributions are invested in equity, corporate bonds and government securities, and at retirement part of the corpus must buy an annuity that pays a lifelong pension. After the December 2025 amendment to the exit regulations, non-government subscribers (All Citizen and corporate) may take up to 80% as a lump sum with at least 20% in an annuity, while government employees take up to 60% with at least 40% annuitised, for corpora above ₹12 lakh.

This calculator invests each monthly contribution at the start of the month and grows it at your expected annual return divided by 12. At retirement it applies your chosen annuity share and estimates the pension as annuity amount × annuity rate ÷ 12. Annuity rates are set by insurers and depend on age and plan type, so 6 to 7% is a reasonable planning range rather than a quote.

How to use NPS Calculator

4. Optionally raise the contribution every year in line with salary growth.
5. Choose your subscriber type and the share of corpus to use for the annuity.
6. Enter an expected annuity rate and read the corpus, lump sum and estimated monthly pension.

Tips for better results

• Your own contribution up to ₹50,000 qualifies for the extra 80CCD(1B) deduction in the old regime, above the ₹1.5 lakh 80C limit.
• Employer contributions under 80CCD(2) are deductible in both regimes, up to 14% of basic plus DA in the new regime.
• Use the yearly increase field; a 5% step-up can raise the final corpus by more than half.
• A higher annuity share means a larger pension but a smaller lump sum; the trade-off depends on your other income.

Common use cases

• Checking whether current NPS contributions will produce the pension you want.
• Deciding how much to contribute to use the 80CCD(1B) deduction.
• Comparing NPS with PPF or mutual-fund SIPs for retirement.
• Showing how the 2025 exit rule changes affect the lump-sum amount.

Common mistakes to avoid

• Treating the expected return as guaranteed; NPS returns depend on markets and fund managers.
• Ignoring inflation; a pension of ₹25,000 in 30 years will buy far less than it does today.
• Assuming the annuity pension is tax-free; it is taxed as income in the year received.
