PPF Calculator: Public Provident Fund Returns & Rules [2026]

The Public Provident Fund (PPF) is one of the most trusted and popular long-term investment instruments in India. Backed by the sovereign guarantee of the Government of India, PPF offers tax-free returns, making it one of the few investments that enjoy the coveted EEE (Exempt-Exempt-Exempt) status. Whether you are a salaried employee, self-employed professional, or homemaker, PPF is a cornerstone of financial planning. In this guide, we cover everything you need to know about PPF — interest rates, rules, tax benefits, and how to maximize your returns.

What is PPF?

The Public Provident Fund is a long-term savings scheme established under the Public Provident Fund Act, 1968. It is available at post offices and designated banks across India. PPF is designed to encourage long-term savings with the safety of government backing.

Here are the key features of PPF:

• Eligibility: Any Indian resident can open a PPF account. NRIs cannot open new PPF accounts (existing accounts can continue until maturity). Hindu Undivided Families (HUFs) are also not eligible.
• Minimum deposit: ₹500 per year to keep the account active.
• Maximum deposit: ₹1,50,000 per year. Deposits above this amount do not earn interest and are not eligible for tax benefits.
• Tenure: 15 years. Can be extended in blocks of 5 years indefinitely.
• Interest rate: Set by the government each quarter. Currently 7.1% per annum (compounded annually).
• Deposit frequency: You can deposit a lump sum or in installments (maximum 12 installments per year). Deposits must be made before the 5th of each month to earn interest for that month.
• Account limit: One PPF account per person. A minor can have a PPF account opened by a parent/guardian.

PPF is ideal for risk-averse investors who want guaranteed, tax-free returns over a long period. It is particularly suitable for building a retirement corpus or a child's education fund.

PPF Interest Rate History

PPF interest rates are reviewed quarterly by the Ministry of Finance. Here is the historical trend of PPF interest rates over the past decade:

Period	PPF Interest Rate
Q2 2026 (Apr-Jun)	7.1%
Q1 2026 (Jan-Mar)	7.1%
FY 2025-26	7.1%
FY 2024-25	7.1%
FY 2023-24	7.1%
FY 2022-23	7.1%
FY 2021-22	7.1%
FY 2020-21	7.1%
FY 2019-20	7.9%
FY 2018-19	8.0%
FY 2017-18	7.8%
FY 2016-17	8.0%–8.1%
FY 2015-16	8.7%

Trend: PPF rates have declined from 8.7% in 2015-16 to 7.1% currently, mirroring the overall decline in interest rates in the Indian economy. However, 7.1% tax-free is equivalent to approximately 10.15% pre-tax for someone in the 30% bracket, making PPF still one of the best risk-adjusted investments available.

PPF Rules — Tenure, Loans & Withdrawals

PPF has specific rules regarding tenure extension, loans, and withdrawals that every investor should know:

15-Year Tenure & Extension

The initial PPF tenure is 15 years from the end of the financial year in which the account was opened. After maturity, you have three options:

• Close the account: Withdraw the entire corpus (principal + interest) tax-free.
• Extend without contribution: The balance continues to earn interest for 5 more years. No fresh deposits allowed. One withdrawal per year is permitted.
• Extend with contribution: Continue depositing up to ₹1.5L per year for another 5 years. You must submit Form H within 1 year of maturity to extend with contribution. If you miss this, you cannot deposit fresh funds.

You can extend in blocks of 5 years indefinitely. Many investors extend their PPF accounts for 25-30 years, allowing the power of compounding to work over very long periods.

Loan from PPF (Year 3 to Year 6)

You can avail a loan against your PPF account from the 3rd financial year to the 6th financial year of opening the account. Key rules:

• Loan amount: Up to 25% of the balance at the end of the 2nd year preceding the loan year.
• Interest rate: 1% more than the prevailing PPF interest rate (currently 8.1%).
• Repayment: Must be repaid within 36 months (3 years). You can repay in lump sum or installments.
• Second loan: A second loan can be taken only after the first loan is fully repaid.

After the 6th year, loans are no longer available, but partial withdrawals become possible.

Partial Withdrawal (From Year 7)

Partial withdrawals are allowed from the 7th financial year onwards. Key rules:

• Maximum withdrawal: Up to 50% of the balance at the end of the 4th year preceding the withdrawal year, or 50% of the balance at the end of the preceding year — whichever is lower.
• Frequency: One withdrawal per financial year.
• No need to repay: Withdrawals are not loans — they reduce your corpus permanently.

Other Important Rules

• Account freezing: If you fail to deposit the minimum ₹500 in a year, the account becomes inactive. You can revive it by paying ₹500 per year of default plus a ₹50 penalty per year.
• Nomination: You can nominate one or more persons. Nomination is strongly recommended to avoid legal complications for your heirs.
• Transfer: PPF accounts can be transferred between post offices and banks, or between banks, free of charge.

PPF vs FD vs ELSS

Choosing between PPF, FD, and ELSS depends on your risk appetite, tax bracket, and investment horizon:

Feature	PPF	5-Year Tax Saving FD	ELSS Mutual Fund
Returns	7.1% (guaranteed, tax-free)	6.5%–7.0% (guaranteed, taxable)	12%–15% (market-linked, taxable above ₹1L LTCG)
Risk	Zero (sovereign guarantee)	Zero (DICGC insured up to ₹5L)	Moderate to high (equity market risk)
Lock-in	15 years	5 years	3 years (shortest among 80C options)
Tax on returns	Tax-free (EEE)	Taxed at slab rate	LTCG above ₹1L taxed at 12.5%
80C benefit	Up to ₹1.5L	Up to ₹1.5L	Up to ₹1.5L
Effective pre-tax return (30% bracket)	~10.15%	~7% (after tax: ~4.9%)	12%–15%

Best strategy: Use PPF for guaranteed tax-free returns and capital preservation. Use ELSS for potentially higher returns with the shortest lock-in. Use tax-saving FD only if you need guaranteed returns and have already maxed out PPF and ELSS. For most investors in the 20% or 30% bracket, PPF's tax-free status makes it superior to FD even though the nominal rate is similar.

PPF Tax Benefits — EEE Status

PPF enjoys the most favorable tax treatment among all investments in India — the EEE (Exempt-Exempt-Exempt) status:

• Exempt 1 — Investment: Deposits up to ₹1.5 lakh per year are deductible under Section 80C.
• Exempt 2 — Interest: Interest earned each year is completely tax-free. You do not pay any tax on the annual interest credited to your PPF account.
• Exempt 3 — Maturity: The entire maturity amount (principal + interest) is tax-free. No TDS, no capital gains tax, nothing.

This triple exemption makes PPF unique. Compare this with FD where interest is taxed annually at your slab rate, or ELSS where long-term capital gains above ₹1 lakh are taxed at 12.5%. For someone in the 30% tax bracket, PPF's 7.1% tax-free return is equivalent to a pre-tax return of approximately 10.15%, making it extremely competitive even against market-linked instruments.

PPF Calculation Example

Let us calculate the maturity value for a PPF account where you deposit ₹1,50,000 per year for 15 years at 7.1% interest:

Over 15 years, your ₹22.5 lakh grows to approximately ₹40.68 lakh — all completely tax-free. If you extend for another 5 years with contributions, the corpus grows even larger thanks to compounding.

Tips to Maximize PPF Returns

1. Deposit before the 5th: PPF interest is calculated on the minimum balance between the 5th and the end of each month. Always deposit before the 5th to earn interest for that month. Depositing on the 10th means you lose interest for that month.
2. Deposit the maximum early in the year: Instead of monthly installments, deposit ₹1,50,000 as a lump sum in April. This ensures the full amount earns interest for all 12 months. The difference can be ₹5,000–₹10,000 over 15 years.
3. Extend beyond 15 years: The real power of PPF is seen with extensions. A PPF account extended for 25-30 years can grow to ₹1 crore+ with consistent maximum contributions, all tax-free.
4. Open PPF for your spouse and children: Each family member can have their own PPF account. A husband and wife can together invest ₹3 lakh per year. A minor child's account (opened by parent) also counts towards the parent's ₹1.5L limit, but after the child turns 18, it gets its own limit.
5. Do not withdraw early: The 15-year lock-in is long, but it is this forced discipline that builds wealth. Avoid taking loans or withdrawals unless absolutely necessary. Let compounding work uninterrupted.
