NPS Calculator

An NPS calculator estimates a retirement corpus and an illustrative pension from monthly contribution, years, and an assumed annual return rate you enter. It treats NPS as a contribution schedule — not a product, PFM, or fund pick — and compounds locally in your browser so you can audit the arithmetic. Education only: not SEBI advice, not a live NAV, and not a pension guarantee.

How the formula works in plain words: convert the annual percent you typed into a monthly rate (annual ÷ 100 ÷ 12). Months equal years × 12. When the monthly rate is greater than zero, corpus = monthly amount × (((1 + monthly rate)^months − 1) ÷ monthly rate) × (1 + monthly rate) — the beginning-of-period / annuity-due educational form. When the rate is zero, corpus equals monthly amount × months. Total contributed is monthly × months; estimated gains are corpus minus total contributed. Illustrative monthly pension = (corpus × annuity share percent ÷ 100) × (assumed annuity rate percent ÷ 100) ÷ 12 — a simple interest-style sketch, not an insurer annuity quote.

Dated caveat (12 September 2026): the expected accumulation rate and assumed annuity rate on this page are always user-typed. Page Utils does not scrape live NPS NAVs, CRA tables, PFM quotes, or annuity purchase rates, and it will not notice when markets or rules move. Pick percents only as sensitivity assumptions for the schedule math — not as a forecast. Page Utils is not SEBI-registered. This tool explains how a contribution schedule compounds under constant rates you supply; it does not recommend securities, name PFMs or funds to buy, or promise returns or pension. Confirm any real NPS account with official materials and a registered intermediary.

NPS contribution-schedule check

Equal contribution each month. Allow ₹500–₹10,00,000.

User-entered expected percent — not a live NAV, PFM quote, or fund return. Example default 10.

Default 25. Allow 1–40.

Structural illustration only (e.g. 40). Allow 0–100. Not a product rule.

Used only for the illustrative monthly pension. Default 6. Not an insurer quote.

Educational NPS-style model: equal monthly contributions at a rate you type. Monthly rate = annual ÷ 12; months = years × 12. Corpus uses the beginning-of-period (annuity-due) form when the rate is positive; when the rate is zero, corpus equals total contributed. Illustrative monthly pension = (corpus × annuity share %) × (assumed annuity rate %) ÷ 12 — a simple interest-style sketch, not an annuity purchase quote. NPS here means a contribution schedule, not a product, PFM, or fund. Page Utils is not SEBI-registered and does not pick funds or guarantee returns or pension. Confirm any real account with official NPS / CRA materials and a registered intermediary.

Accumulation rate is user-entered (10% p.a.), not a live market or PFM figure. Estimated gains = corpus − total contributed under this simplified schedule. Illustrative pension uses 40% of corpus at an assumed 6% p.a. interest-style annuity sketch — not guaranteed, not an insurer quote, and not advice. Real NPS outcomes vary with asset allocation, fees, annuity purchase terms, and rules. Output is a local educational check only.

How does the NPS Calculator work?

  1. 1. Enter the monthly contribution in rupees

    Type the equal contribution you want to model each month. The example loads ₹5,000. Allowed range for this check is ₹500 to ₹10,00,000. Nothing is uploaded.

  2. 2. Type an expected annual accumulation rate yourself

    The percent is user-entered, not scraped. Use it only as a what-if assumption for the schedule. This page never pulls live NAVs or names a PFM or fund as advice.

  3. 3. Choose years (horizon) and optional annuity assumptions

    Default horizon is 25 years (1–40). Annuity share defaults to 40% of corpus and assumed annuity rate to 6% — structural illustration knobs, not product rules or insurer quotes.

  4. 4. Read corpus, contributed total, gains, and illustrative pension

    Corpus is the educational future value. Total contributed is monthly × months. Estimated gains are corpus minus total contributed. Illustrative monthly pension is a simple interest-style sketch on the annuity share. Copy the result if you want a local note — then confirm any real account elsewhere.

Questions about NPS Calculator

What is NPS here, structurally, and what does this calculator model?
A contribution schedule / retirement accumulation model under user-entered assumptions — not a scheme you buy on this site. Outputs are educational projections from monthly contribution, rate, and horizon, plus an optional illustrative pension sketch. It is not a PFM picker and not a product purchase flow.
Are the corpus or pension figures guaranteed returns?
No. Projections are illustrative from assumptions you type. Markets, fees, annuity purchase terms, and rules can make real outcomes higher or lower. The page does not promise or underwrite returns or pension.
Is this financial advice or a recommendation of which fund / PFM to choose?
No. Page Utils / the publisher is not SEBI-registered. Content is education-only on how contribution schedules compound under an assumed rate. No named-fund picks, no PFM rankings, no buy/sell/hold.
How are Tier I and Tier II treated if mentioned?
Structure-only labels if they appear in surrounding copy. This calculator does not rank tiers as products, invent tax-advice conclusions, or model every NPS rule. Keep your real-account questions with official NPS / CRA materials.
How does the corpus formula work?
Monthly rate r = (annual percent ÷ 100) ÷ 12. Months n = years × 12. When r > 0, corpus = P × (((1+r)^n − 1) / r) × (1+r), the beginning-of-period educational form. When r = 0, corpus = P × n. Total contributed = P × n; estimated gains = corpus − total contributed. Amounts are formatted in Indian rupees (en-IN).
How is the illustrative monthly pension calculated?
Annuity corpus = corpus × (annuity share percent ÷ 100). Illustrative monthly pension = annuity corpus × (assumed annuity rate percent ÷ 100) ÷ 12. That is a simple interest-style sketch for education — not an annuity purchase quote, not longevity pricing, and not a guarantee.
Is my contribution data uploaded or stored?
No. Inputs stay in the browser tab; nothing is posted to a server, saved to localStorage/cookies, or tied to a name/email. Closing the tab clears the workspace. Hosting logs may show that you opened this URL; they do not contain the rupee amounts from the form.
How is this different from the SIP, PPF, and FD tools on this hub?
Post Office FD and LIC FD estimate deposit maturity from a lump-sum principal, a rate you type, and tenure. PPF uses an annual-deposit educational model with a year-by-year table. SIP models equal monthly deposits (a payment schedule) at a user-entered expected rate. NPS adds an optional illustrative pension sketch on a share of the same style of corpus. They are not interchangeable products and do not rank lock-in, tax treatment, or returns across schemes.
