NPS calculator formula
The calculator grows the existing NPS balance and each monthly contribution up to the chosen exit age. It then splits the corpus.
Monthly rate = (1 + yearly return)^(1 ÷ 12) − 1 Projected corpus = grown existing balance + grown monthly contributions Annuity amount = projected corpus × annuity share Lump-sum amount = projected corpus − annuity amount Estimated monthly pension = annuity amount × annuity payout rate ÷ 12
The saved 20% annuity assumption reflects the general All Citizen normal-exit framework reviewed for this version. Other subscriber models and exit cases can use different rules.
The pension figure is only a simple annuity-rate estimate. A real quote depends on provider, age and the annuity option selected.
Example with numbers
A person aged 30 pays ₹10,000 a month until age 60. At a steady 10% return, estimated corpus is about ₹2.06 crore. If 20% buys an annuity at a 6% payout rate, the simple result is about ₹1.65 crore lump sum and ₹20,628 monthly pension before tax and provider terms.
What is an NPS calculator?
NPS means National Pension System. It is market-linked, so its future value is not fixed.
This NPS calculator estimates the retirement corpus and then shows a chosen split between lump sum and annuity. The annuity part is used to estimate a monthly pension.
How to use the NPS calculator
- Enter the monthly contribution, current age and planned exit age.
- Enter the yearly NPS return and annuity payout rate you want to test.
- Add an existing NPS balance in Advanced options if you have one.
- Check the annuity share for your subscriber model and exit type before reading the split.
What the results mean
- Future contributions: monthly payments made until the chosen exit age.
- Projected corpus: estimated market-linked balance at exit.
- Lump-sum amount: the part not allocated to an annuity in this example.
- Estimated pension: annuity amount times the entered payout rate, divided by twelve.
How this NPS calculation works
The existing balance starts growing immediately. Each end-of-month contribution then gets fewer growth months than the contribution before it.
Changing the annuity share changes the displayed split, not the pre-exit corpus. More annuity means a higher simple pension estimate and a smaller lump-sum amount.
Why an NPS calculator is useful
- It combines an existing balance and future contributions.
- It keeps corpus growth separate from the exit split.
- It allows the annuity share and payout rate to be changed.
- It shows the growth path instead of only one pension number.
Why the real NPS result may be different
NPS returns change with asset mix, fund manager, charges, markets and contribution dates. They are not guaranteed.
Exit rules depend on subscriber model, age, corpus and exit type. A real annuity quote and tax treatment may also differ.

Frequently asked questions
Is NPS return guaranteed?
No. NPS is market-linked. The calculator uses the return entered by you.
What annuity share does this calculator use?
If blank, it uses the saved 20% general All Citizen normal-exit assumption for this version. Other cases can differ.
Is the monthly pension guaranteed?
No. It is a simple estimate. A provider’s real annuity quote depends on age and option.
Can I add my current NPS balance?
Yes. Enter it in Advanced options and it will grow with future contributions.
Why do older calculators show a 40% annuity?
Some pages still reflect older rules or another subscriber and exit case. Always check the current model-specific rule.
