PPF Calculator
Project PPF maturity with deposits or interest-only extension after maturity. Includes year-wise schedule and optional inflation adjustment.
Last updated: 5 October 2026. PPF rates and rules are notified by the Government of India and may change each quarter — verify on the National Savings Institute or India Post website.
What is the Public Provident Fund (PPF)?
The Public Provident Fund (PPF) is a government-backed long-term savings scheme designed to encourage retirement and goal-based saving among resident individuals. Accounts can be opened at authorised banks and post offices. Deposits qualify for deduction under Section 80C, and both interest and maturity proceeds are tax-free for eligible holders — often described as EEE (Exempt-Exempt-Exempt) status.
PPF is administered under the Public Provident Fund Scheme, 2019, with operational oversight from the National Savings Institute under the Department of Economic Affairs, Ministry of Finance.
How to use this PPF calculator
Choose With deposits for the initial tenure or Form-4 extensions with fresh contributions, or Interest only for extension without deposits. For deposits, pick monthly/quarterly/yearly frequency within the ₹1.5 lakh yearly cap. Enter years (up to 50 for long extensions), rate, and current balance for mid-tenure or interest-only projections. Optional inflation shows purchasing-power-adjusted maturity.
Advantages of a PPF calculator
Avoid error-prone annuity maths when deposits and rates change. Test how much you need to deposit to approach a goal, estimate your annual 80C usage, and compare monthly vs yearly deposit timing. Inflation chips help separate nominal maturity from real purchasing power.
PPF interest rate and how it is revised
PPF interest is not set by individual banks. The Government of India notifies rates quarterly for PPF and other small savings schemes. Banks and post offices apply the notified rate for the relevant quarter.
Indicative rate as of 5 October 2026: 7.1% p.a. (Q3 FY 2026-27, 1 Oct–31 Dec 2026; subject to quarterly revision). Use the rate field in the calculator above to model different scenarios if a new notification is published.
How PPF maturity is calculated
Choose monthly, quarterly or yearly deposits. Yearly mode assumes a lump-sum at the start of each financial year with annual compounding. Monthly and quarterly modes approximate the scheme's minimum-balance method (deposit before the 5th).
The standard formula for equal annual contributions is: F = P × [((1 + i)n − 1) / i] × (1 + i), where P is the annual deposit, i is the annual rate as a decimal, and n is the number of years.
Worked example: ₹1,50,000 deposited each year for 15 years at 7.1% p.a. gives an estimated maturity of ≈ ₹40,68,209 (total interest ≈ ₹18,18,209). Use the growth chart and year-wise schedule below the calculator for the path of invested amount vs corpus. Optional inflation chips show purchasing-power-adjusted maturity.
EEE tax status explained
Contribution: Deposits up to ₹1.5 lakh per financial year count toward your Section 80C deduction limit (shared with ELSS, life insurance premium, home loan principal, etc.).
Interest: Credited to the account is not included in your taxable income while you remain eligible under the scheme.
Maturity: The amount received on withdrawal at maturity is tax-free for resident individuals, subject to current Income Tax Act provisions.
Key features of PPF
15-year lock-in with optional 5-year extensions; EEE tax treatment for eligible residents; government-notified rate (revised quarterly); partial withdrawal from year 7; loan facility in years 3–6; nomination; and transfer between authorised banks/post offices. There is no market risk on the principal — returns depend on notified rates.
Lock-in, extension and withdrawals
The account matures after 15 complete financial years. Before maturity, partial withdrawals are allowed from the 7th year within limits linked to earlier balances. Loan facility is available between the 3rd and 6th years against a portion of your balance.
After 15 years you may close the account and withdraw fully, or extend in blocks of 5 years. To keep depositing, file Form-4 (Form H) within one year of maturity. If you do not opt in, the account typically continues earning interest without fresh deposits — use the Interest only mode with your matured balance to model that path.
Eligibility and how to open an account
Resident individuals may open one PPF account in their own name. Parents or guardians may open an account for a minor. Non-resident Indians (NRIs) cannot open new accounts; rules for accounts opened before NRI status apply per current government guidance.
Open at a designated bank branch or post office with PAN, identity and address proof, and photographs. Minimum deposit is ₹500 per financial year; maximum is ₹1.5 lakh. Missing the minimum in a year may attract penalties per scheme rules.
PPF vs EPF vs NPS
PPF is voluntary and self-directed. EPF applies mainly to salaried employees with mandatory employer participation. NPS is a market-linked pension scheme with its own withdrawal and tax rules. Compare lock-in, risk and tax treatment before choosing.
| Feature | PPF | EPF | NPS (Tier I) |
|---|---|---|---|
| Who can open | Resident individuals (one account per person); minors via guardian | Salaried employees where employer offers EPF | Any Indian citizen aged 18–70 |
| Contribution limit | ₹500–₹1.5 lakh per financial year | 12% of basic wages (employee + employer share) | No annual cap; additional ₹50,000 under 80CCD(1B) for extra deduction |
| Lock-in / access | 15-year block; partial withdrawal from year 7; extension in 5-year blocks | Till retirement / resignation; partial withdrawal for specific purposes | Tier I locked till age 60 (with exit rules); Tier II voluntary |
| Tax on returns | Exempt — EEE (contribution, interest, maturity) | Exempt subject to conditions; interest on high balances may be taxable | Partially exempt; lump sum and annuity taxed per rules at exit |
| Section 80C | Eligible up to ₹1.5 lakh/year | Employee contribution eligible under 80C | Employee contribution under 80CCD(1); employer under 80CCD(2) |
| Rate / return basis | Government-notified rate, revised quarterly | EPFO-declared rate on pooled corpus | Market-linked (debt/equity mix chosen by subscriber) |
Who typically considers PPF?
PPF suits long-term savers who want sovereign-backed returns with tax-free compounding — often parents saving for education, professionals building a retirement corpus alongside equity, or anyone maximising Section 80C with a safe instrument.
It may be less suitable if you need liquidity within five years or want potentially higher (but market-linked) returns without lock-in. Compare with an FD or RD for shorter horizons. This is educational content, not personal financial advice.
Frequently asked questions about PPF
What is the Public Provident Fund (PPF)?
PPF is a long-term small savings scheme backed by the Government of India, offered through designated banks and post offices. It combines a 15-year investment horizon with tax benefits under Section 80C and tax-free interest and maturity proceeds (EEE status) for resident individuals.
How do I use this PPF calculator?
Choose contribution mode: With deposits (initial tenure or Form-4 extension with fresh contributions) or Interest only (extension without deposits). For deposits, pick monthly/quarterly/yearly frequency within the ₹1.5 lakh yearly cap. Enter amount, years (up to 50 for long extensions), rate, optional current balance, and optional inflation.
How is PPF interest calculated?
PPF interest is credited yearly. Yearly mode models a lump-sum deposit at the start of each year. Monthly and quarterly modes approximate the official method: interest accrues on the lowest balance between the 5th and month-end, with deposits assumed before the 5th. Small differences from bank/post-office passbooks are normal.
What is the current PPF interest rate?
The Ministry of Finance notifies PPF rates quarterly along with other small savings schemes. As of the latest notification referenced on this page, the indicative rate is 7.1% p.a. — verify the current rate on the National Savings Institute or India Post website before depositing.
How much will I get after 15 years in PPF?
It depends on how much you deposit each year and the prevailing rate. At the maximum ₹1.5 lakh per year for 15 years at 7.1% p.a. (yearly mode), maturity is about ₹40.7 lakh. Use the calculator for your own deposit amount, frequency and opening balance.
What does EEE tax status mean for PPF?
EEE stands for Exempt-Exempt-Exempt: contributions up to ₹1.5 lakh per year qualify for deduction under Section 80C (within the overall 80C cap), interest earned is not taxed, and the maturity amount is tax-free in the hands of a resident individual, subject to scheme rules.
What is the PPF lock-in period?
The initial maturity period is 15 financial years from the end of the year in which the account was opened. After maturity you may withdraw fully, extend with deposits (Form-4 / Form H within one year, in 5-year blocks), or keep the account without fresh deposits while interest continues. Use With deposits or Interest only in this calculator, with your current balance for extension projections.
What is extension without contributions?
If you do not opt to continue depositing within one year of maturity, the account typically continues earning the notified PPF interest with no fresh deposits (and usually one withdrawal per year). Choose Interest only, enter your matured balance, and set how many years to leave it invested. If you want to keep depositing, you must file Form-4 for a 5-year block and use With deposits instead.
Can I withdraw from PPF before 15 years?
Partial withdrawals are permitted from the 7th financial year onward, subject to limits prescribed in the PPF scheme (linked to balances in preceding years). Premature closure is allowed only in specific circumstances such as serious illness or higher education, per government rules.
Can I take a loan against my PPF balance?
Yes. A loan against PPF is available between the 3rd and 6th financial years, up to a percentage of the balance at the end of the second preceding year. Loan interest is charged at a rate prescribed in the scheme. A second loan is not allowed until the first is repaid.
Can NRIs open a PPF account?
NRIs cannot open a new PPF account. If residential status changes to NRI after an account was opened, the account may be continued until maturity per existing rules — confirm current RBI and Ministry of Finance guidance.
How do I open a PPF account?
Visit a designated bank branch or post office with KYC documents (PAN, Aadhaar, photographs) and complete the account opening form. Many banks also offer online PPF opening for existing customers. Only one PPF account is permitted per individual. Accounts can usually be transferred between authorised banks/post offices.
Can I project from my current PPF balance?
Yes. Enter your current passbook balance and the years remaining (or extension years). With deposits compounds the opening balance plus fresh contributions; Interest only grows the opening balance with annual interest and ₹0 deposits.
Can I deposit monthly or quarterly instead of yearly?
Yes. The calculator supports monthly, quarterly and yearly deposits (capped so total stays within ₹1.5 lakh per financial year). Earlier deposits within a year usually earn slightly more under the official minimum-balance method than a late lump sum; yearly mode assumes deposit at the start of each year.
What does the inflation adjustment show?
Optional inflation (e.g. 4%, 6%, 8%) discounts the maturity amount to today's purchasing power so you can see real returns after price rise. It does not change your actual PPF balance.
What does the invested vs corpus chart show?
The area chart compares cumulative deposits (plus opening balance, if any) with the growing PPF corpus over time. The schedule table lists year-wise opening, deposit, interest and closing.
PPF vs FD — which gives better post-tax returns?
PPF offers tax-free interest and maturity for eligible residents, which improves post-tax returns when you stay invested for the full horizon. FD interest is taxable at your slab rate. Compare gross and post-tax figures using our PPF and FD calculators for your tenure and tax bracket.
PPF calculator — maturity value if I invest ₹1.5 lakh every year for 15 years?
Enter yearly contribution (max notified limit), current PPF rate and 15-year tenure. Interest is compounded annually per PPF rules. Rate can change by government notification; projection is not a guarantee.
Can I continue PPF after 15 years with or without contribution in India?
Yes — you can extend in 5-year blocks with or without fresh deposits, subject to account rules. Use extension options in the calculator for illustration and confirm bank/post-office procedures.
Disclaimer: Projections from the calculator are illustrative. Official interest calculation uses monthly balances. Confirm current rates and rules with your bank, post office or the National Savings Institute before investing.
