What is NPS Calculator?
NPS Calculator helps you estimate an NPS corpus and the split between withdrawal and annuity purchase.
The main result is projected NPS corpus, with a breakdown of annuity purchase amount, remaining lump sum and illustrative monthly annuity. The formula, example and assumptions below explain how to interpret it.
How to use NPS Calculator
Use the example to get familiar with the form, then enter your own figures. Any rates in the example are illustrative. Check the field labels and units before calculating.
- Gather monthly NPS contribution (₹), expected annual return (%), investment duration (years), corpus used for annuity (%) and expected annuity annual payout rate (%). Use values from the same situation or reporting period.
- Replace the example monthly NPS contribution with your own value, then complete the other fields. Check the displayed units.
- Select Calculate and read projected NPS corpus with its result breakdown. Change one input and calculate again to compare a second scenario. Reset restores the original example.
- Enter monthly NPS contribution in ₹, at least 0. Decimals are accepted.
- Enter expected annual return in %, at least 0 and at most 100. Decimals are accepted.
- Enter investment duration (years), at least 1 and at most 60. Use a whole number.
- Enter corpus used for annuity in %, at least 0 and at most 100. Decimals are accepted.

Understanding the NPS result
Read projected NPS corpus alongside annuity purchase amount, remaining lump sum and illustrative monthly annuity. These describe different parts of the same calculation.
Displayed results use a readable number of decimal places. When checking a result by hand, keep extra precision until the last step. To compare scenarios, change one input at a time and keep the others fixed.
- Example Annuity purchase amount: ₹4,60,077.38
- Example Remaining lump sum: ₹6,90,116.07
- Example Illustrative monthly annuity: ₹2,300.39
NPS Calculator: assumptions and common mistakes
A useful estimate starts with the right inputs. Check the following assumptions and limits before applying the result to your situation.
- Projection using the rate you enter, not a guaranteed return or live product quote. Unless stated otherwise, taxes, fees and inflation are excluded.
- Annuity pricing and exit rules depend on age, subscriber category, corpus and chosen annuity option. This is not an insurer quote or eligibility check.
- A projected return is an assumption. Check whether fees, tax and inflation are included before comparing products.
