What is the NPS Calculator?
NPS helps build a retirement corpus through regular contributions. This calculator estimates corpus, annuity amount and pension from monthly contribution, expected return, investment years, annuity share and annuity rate.
Formula used
Formula: Corpus uses SIP-style future value. Monthly pension estimate = annuity corpus x annuity return / 12.
For NPS estimates, treat return and annuity rate as assumptions, then compare a conservative pension case with your expected case.
Input guide
| Monthly contribution | Regular amount invested for retirement. |
|---|---|
| Expected return | Growth assumption during accumulation. |
| Annuity share | Part of corpus used to buy annuity. |
| Pension estimate | Monthly income estimated from annuity corpus. |
Real-world examples and use cases
- Compare retirement corpus at different contribution levels.
- Check the effect of increasing investment years.
- Compare annuity percentage choices.
- Estimate a rough pension before reviewing official NPS rules.
Common mistakes
- Treating expected return as guaranteed.
- Confusing annuity return with investment return.
- Ignoring inflation when reading pension values.
- Forgetting tax, charges and withdrawal rules.
Limitations of this calculator
This page does not include NPS charges, fund selection, tax treatment, withdrawal rules or annuity provider terms.
How to use this result
This page is most useful for NPS retirement corpus planning. Start with values that match your real situation, then change one input at a time to understand what affects the result most.
Use the result for testing whether monthly retirement contributions may support a future corpus and pension estimate. If the number will be used for an official, financial, technical or purchase decision, keep the input values with the result so the estimate can be checked later.
Practical comparison table
| Higher monthly contribution | Increases the corpus directly over the full investment period. |
|---|---|
| Longer investment period | Gives compounding more time to work. |
| Higher annuity share | Can increase pension estimate but reduce lump-sum amount. |
Before you rely on the answer
- Treat expected return as an assumption, not a promise.
- Review annuity share carefully.
- Compare pension value with inflation and expected expenses.
NPS planning notes
NPS estimates should be read with retirement age, inflation and annuity assumptions in mind. A high corpus may still need careful pension planning if future monthly expenses are also high.
| Situation | What to check |
|---|---|
| Corpus planning | Compare conservative and moderate return assumptions. |
| Pension planning | Check whether the annuity share gives enough monthly income. |
