What is PPF Account?

PPF (Public Provident Fund) is a government-backed long-term savings and investment scheme in India, launched in 1968 by the National Savings Institute under the Ministry of Finance. It is one of the most popular tax-saving instruments in the country, combining guaranteed returns with complete tax exemption.

The scheme operates under the Public Provident Fund Act, 1968 (now governed by the Government Savings Promotion Act, 2019). Your principal, interest earned, and maturity amount are all backed by the sovereign guarantee of the Government of India — making it essentially risk-free.

Over 8 crore PPF accounts are active in India today, held through post offices and authorised banks. The scheme has a lock-in period of 15 years and currently offers an interest rate of 7.1% per annum (compounded annually), as announced by the Ministry of Finance for Q1 FY2025-26.

Key Features & Current Rules (2025)

Before opening a PPF account, you need to understand its core parameters. These are set by the Government of India and updated periodically through official notifications.

Who Can Open a PPF Account?

Any resident Indian individual can open a PPF account. This includes salaried employees, self-employed professionals, business owners, and even homemakers. Non-resident Indians (NRIs) who held a PPF account before becoming NRI can continue it till maturity but cannot open a new one.

You can also open a PPF account in the name of a minor child (below 18 years), with yourself as the guardian. However, the combined deposit limit of ₹1.5 lakh applies across both accounts — adult’s own account plus minor’s account.

Hindu Undivided Families (HUFs) and trusts are not eligible to open PPF accounts.

Tax Benefits — The Triple Exemption Explained

The biggest reason PPF remains unbeatable for long-term savers is its EEE tax status — the only such status available to Indian retail investors in a government-backed product.

To put this in perspective: if you invest ₹1.5 lakh per year and are in the 30% tax bracket, you save ₹46,800 in tax every single year through Section 80C. Over 15 years, that’s a tax saving of approximately ₹7 lakh — before even counting the interest on the tax you saved.

PPF Under New Tax Regime (NTR)

Under the New Tax Regime introduced in Budget 2020 (and revised in 2023), the Section 80C deduction is not available. However, the interest exemption under Section 10(11) continues — meaning PPF interest is still tax-free even if you choose the new regime. This makes PPF a great long-term savings tool regardless of which regime you choose.

You can open a PPF account either online (net banking) or by visiting a branch in person. The process takes 15–30 minutes.

How PPF Interest is Calculated

The PPF interest calculation has some nuances that every investor must understand to optimise their returns.

The Monthly Balance Method

Interest is calculated monthly on the minimum balance between the 5th and last day of the month. Even though interest is calculated monthly, it is credited to your account only once a year — on 31st March.

The formula is: Monthly Interest = (Balance × 7.1%) ÷ 12

All monthly interest figures are summed and credited on 31 March. This credited interest then becomes part of your principal, so next year’s interest is calculated on a larger base — creating the compounding effect.

When Does Compounding Actually Happen?

Technically, PPF compounds annually — because interest is added to the principal only once a year on 31st March. This is different from bank FDs where some compound quarterly or monthly. However, because the credited interest earns interest in subsequent years, the effective compounding over 15 years is highly powerful.

Worked Example: ₹1.5 Lakh/Year for 15 Years

Let’s see exactly how much a maximum PPF deposit grows at the current 7.1% interest rate over the full 15-year tenure.

This means you invest ₹22.5 lakh over 15 years and receive a tax-free corpus of over ₹40.68 lakh — a wealth gain of ₹18.18 lakh purely from interest, with zero tax liability.

If you extend the account by one block of 5 years with continued deposits (maximum allowed), your corpus grows to approximately ₹66.58 lakh over 20 years at the same rate.

Important Rules and Limits

Extension After 15 Years

When your 15-year account matures, you have three choices:

1. Close the account and withdraw the full corpus (tax-free).
2. Extend without deposits — The account continues in blocks of 5 years, earning interest at the prevailing rate. No new deposits required. You can make partial withdrawals once per year.
3. Extend with deposits — Continue depositing up to ₹1.5 lakh/year and claim 80C benefits (Old Regime only). You must submit Form H within 1 year of maturity to avail this option.

Partial Withdrawal Rules

Partial withdrawal is allowed from the 6th financial year (i.e., from Year 7 of the account). The maximum you can withdraw is 50% of the balance at the end of the 4th year preceding the year of withdrawal, or the balance at the end of the immediately preceding year — whichever is lower. Only one withdrawal is permitted per financial year.

Premature Closure

PPF accounts can be closed prematurely only after 5 full financial years, and only in specific circumstances: life-threatening illness of the account holder or family members, higher education expenses of the account holder or dependent children, or change in residential status (becoming NRI). A penalty of 1% reduction in interest rate applies for premature closure.
