What Is a PPF Calculator?

A PPF calculator is a tool that estimates the future value of a Public Provident Fund account based on your yearly contribution, an assumed interest rate and the number of years you plan to contribute. It turns a series of yearly deposits and compounding interest into a single estimated maturity figure, so you can compare different contribution levels and tenures without doing the year-by-year math yourself.

What Is PPF (Public Provident Fund)?

The Public Provident Fund is a long-term savings scheme backed by the Government of India, commonly used for retirement planning, tax-saving and long-term financial goals. Contributions made within prescribed limits are eligible for a deduction under Section 80C of the Income Tax Act, and PPF accounts can be opened at eligible post offices and banks. Because it's a government scheme, PPF is generally viewed as a lower-risk savings option relative to market-linked investments, though "lower risk" doesn't mean the terms, rates or rules are fixed forever — they are set and periodically reviewed by the government.

How Does a PPF Calculator Work?

1. You enter an annual contribution amount.
2. You enter or select an assumed annual interest rate.
3. You choose an investment duration in years.
4. The calculator works through the deposits year by year: each year it adds your yearly deposit to the balance, then applies interest for that year to the updated balance.
5. After the chosen number of years, the resulting balance is shown as the estimated maturity amount.

PPF Calculator Formula

This calculator uses a simplified annual model: it adds your full yearly deposit to the balance once per year, then applies the annual interest rate to the entire updated balance for that year, and repeats this for each year of the tenure you select. This is different from how an actual PPF account works in practice — real PPF interest is calculated monthly on the lowest balance between the 5th and last day of each month, then credited to the account once a year at year-end, which means deposit timing within the year can affect the exact interest earned. This calculator's year-by-year model is a reasonable estimate for planning purposes, but it will not exactly match an official passbook calculation down to the rupee.

PPF Calculator Example

You can reproduce any of these by entering the same yearly deposit, rate and tenure into the calculator above. These are estimates generated from this calculator's own logic, not official government maturity figures.

PPF Maturity After 15, 20 and 25 Years

A standard PPF account matures after 15 years. Continuing to contribute the maximum ₹1,50,000 per year at an assumed 7.1% for the full 15-year term gives an estimated maturity of about ₹40,68,209 in this calculator's model.

After the initial 15 years, an account holder can extend the account in blocks of 5 years, with or without further contributions, subject to applicable rules. Extending to 20 years at the same ₹1,50,000/7.1% assumption gives an estimated maturity of about ₹66,58,288, and extending to 25 years gives an estimated maturity of about ₹1,03,08,015 — illustrating how continued contributions over a longer horizon can meaningfully increase the estimated corpus, assuming the rate stays constant, which it may not.

Use the Tenure field above to model your own extension scenario.

PPF Contribution Rules

Under current rules, the minimum PPF contribution is ₹500 and the maximum is ₹1,50,000 per financial year, which can be deposited as a lump sum or in up to 12 instalments. These limits are set by the government and can change, so verify the current limits on an official source such as India Post or the National Savings Institute before finalizing your contribution plan.

PPF Tax Benefits

PPF is commonly described as following an EEE (Exempt-Exempt-Exempt) tax treatment under current rules: contributions (up to the applicable Section 80C limit) qualify for a tax deduction, the interest earned is generally tax-free, and the maturity amount is generally tax-free as well. Tax rules can change over time, so this should be verified against current Income Tax Department guidance rather than assumed to be permanent, and this page does not constitute personalized tax advice.

PPF Withdrawal and Loan Rules

Under commonly cited PPF rules, partial withdrawal is generally permitted from the 7th financial year onwards, and a loan against the PPF balance is generally available in an earlier window of the account's life, both subject to specific eligibility conditions and limits set by the scheme. Exact eligibility windows, withdrawal limits and loan terms are set by the government and can be revised, so please verify the current rules on an official source, such as India Post or the National Savings Institute, before relying on them for a financial decision.

PPF Account Extension

After the initial 15-year term, PPF accounts can generally be extended in blocks of 5 years, either with or without making further contributions, subject to the applicable rules and the process required to opt for extension. Extended accounts continue to earn interest at the rate applicable at the time.

Who Should Use a PPF Calculator?

• Long-term savers planning a fixed yearly contribution over many years
• People comparing PPF against other tax-saving or long-term savings options
• Anyone estimating retirement or education-fund growth over a 15+ year horizon
• Investors comparing how different contribution amounts affect the estimated maturity value

This calculator gives you a starting estimate — it isn't personalized financial advice, and actual outcomes depend on the rate the government sets each quarter and the rules in force at the time. If you're also considering market-linked or lump-sum options, our SIP Calculator and FD Calculator may help you compare.
