PPF Calculator – Calculate Public Provident Fund Maturity, Interest & Tax-Free Returns

The Public Provident Fund (PPF) remains one of the most trusted long-term savings instruments in India. Backed by the Government of India, it offers guaranteed returns, complete tax exemption under the EEE (Exempt-Exempt-Exempt) category, and a disciplined 15-year lock-in that helps build a substantial corpus. Whether you are a salaried professional maximising Section 80C benefits, a self-employed individual seeking safe returns, or a parent planning for a child’s future, a reliable PPF calculator helps you see exactly how your annual deposits can grow over time.

This free PPF calculator is designed to be accurate, transparent, and practical. It uses the current interest rate of 7.1% per annum (compounded annually), supports existing balances, allows custom tenure including extensions beyond 15 years, and generates a clear year-by-year breakdown so you can track opening balance, deposit, interest earned, and closing balance for every year. The interface is minimal, lightweight, and free of distractions—perfect for embedding in any WordPress page via custom HTML.

What is the Public Provident Fund (PPF)?

The Public Provident Fund is a long-term savings-cum-tax-saving scheme introduced by the Government of India in 1968. It is available through most banks and post offices. Any resident Indian individual can open one PPF account in their own name. A guardian can also open an account on behalf of a minor. Hindu Undivided Families (HUFs) and Non-Resident Indians (NRIs) cannot open new PPF accounts, although existing NRI accounts may continue until maturity under certain conditions.

Key features that make PPF popular include a sovereign guarantee on both principal and interest, a fixed interest rate reviewed quarterly by the Ministry of Finance, a 15-year lock-in period that can be extended indefinitely in blocks of five years, and full tax exemption on contributions (under Section 80C up to ₹1.5 lakh), interest earned, and maturity proceeds.

Current PPF Interest Rate and How It Is Calculated

As of 2026, the PPF interest rate stands at 7.1% per annum. This rate has remained unchanged since April 2020—one of the longest stable periods in the scheme’s history. The Ministry of Finance reviews small savings rates every quarter (April, July, October, and January) and announces any revisions.

Interest is calculated monthly on the lowest balance standing in the account between the close of the 5th day and the end of the month. These monthly interest amounts are accumulated and credited to the account on 31 March every year. Because interest is calculated on the minimum balance during that window, depositing before the 5th of the month ensures the new deposit earns interest for the full month. Depositing after the 5th means the amount earns interest only from the following month.

Although interest is computed monthly, compounding happens annually. The interest credited on 31 March becomes part of the principal for the next financial year, creating the powerful effect of compound growth over the 15-year (or longer) tenure.

PPF Deposit Rules: Minimum, Maximum and Frequency

You must deposit a minimum of ₹500 in every financial year to keep the account active. The maximum deposit allowed in a financial year is ₹1,50,000. This limit applies across all deposits made in that year, whether in one lump sum or multiple instalments. Excess deposits beyond ₹1.5 lakh do not earn interest and are not eligible for Section 80C deduction; the excess is usually refunded without interest.

You can make deposits as many times as you like during the year, subject to the annual ceiling. Many investors prefer a single annual deposit early in the financial year (preferably by 5 April) so that the entire amount earns interest for all 12 months. Others prefer monthly or quarterly transfers for cash-flow convenience. Both approaches work; the calculator assumes a yearly deposit made at the beginning of each year for simplicity and maximum interest credit.

Lock-in Period, Withdrawals, Loans and Extensions

The mandatory lock-in period for a PPF account is 15 years. After maturity you have three options: withdraw the entire amount, extend the account for another five years without further contributions (the balance continues to earn interest), or extend it for five years while continuing to make fresh deposits (subject to the annual limit).

Partial withdrawals are allowed from the seventh financial year onwards. The maximum amount that can be withdrawn is 50% of the balance at the end of the fourth year preceding the year of withdrawal or at the end of the preceding year, whichever is lower. Only one withdrawal is permitted per financial year.

A loan facility is available from the third financial year up to the sixth financial year. The maximum loan is 25% of the balance at the end of the second year preceding the year in which the loan is applied for. The loan must be repaid within 36 months, and interest is charged at 1% above the prevailing PPF rate.

Premature closure is permitted after five years only in specific cases such as serious illness or higher education of the account holder or dependent children, or when the account holder becomes a non-resident. A penalty of 1% reduction in the interest rate for the entire period applies in such cases.

Tax Benefits of PPF – The EEE Advantage

PPF enjoys the highly desirable Exempt-Exempt-Exempt (EEE) tax status:

• Exempt at investment – Contributions up to ₹1.5 lakh per financial year are eligible for deduction under Section 80C of the Income Tax Act (available only under the old tax regime).
• Exempt during growth – Interest earned every year is completely tax-free. It does not form part of your taxable income.
• Exempt at maturity – The entire maturity amount, including all accumulated interest, can be withdrawn tax-free.

This triple tax benefit makes PPF especially attractive for investors in higher tax brackets who are still using the old tax regime. Even under the new tax regime, the interest and maturity remain tax-free, although the upfront 80C deduction is not available.

How This PPF Calculator Works

The calculator uses the standard future-value formula for an annual annuity plus the future value of any existing balance. It assumes that each year’s deposit is made at the beginning of the year so that it earns a full year’s interest. Interest is compounded annually at the rate you enter (default 7.1%).

For each year the tool calculates:

• Opening balance (previous closing balance)
• Deposit made during the year
• Interest earned on (opening balance + deposit)
• Closing balance = opening balance + deposit + interest

At the end of the chosen tenure you see the final maturity amount, the total sum you invested, and the total interest earned. The year-by-year table lets you observe how compounding accelerates growth in the later years—a key reason why starting early and staying consistent produces powerful results.

Example: Maximum Annual Investment for 15 Years

If you invest the maximum ₹1,50,000 every year for 15 years at 7.1% interest, the approximate results are:

• Total amount invested: ₹22,50,000
• Total interest earned: approximately ₹18,18,209
• Maturity amount: approximately ₹40,68,209

These figures assume deposits are made early enough each year to earn full interest and that the 7.1% rate remains constant. Actual results will vary if the government revises the rate in future quarters.

Why Use a PPF Calculator Before Investing?

A good PPF calculator removes guesswork. It shows you the concrete impact of different annual investment amounts, longer or shorter tenures, and the effect of an existing balance. You can quickly test scenarios such as “What if I invest only ₹1 lakh per year?” or “What happens if I extend the account for another five years after maturity?” Seeing the numbers helps you decide how much to allocate to PPF versus other instruments such as equity mutual funds, NPS, or fixed deposits.

It also highlights the power of compounding. In the early years the interest component looks modest. By year 10–15 the interest earned each year often exceeds the annual deposit itself. Visualising this progression encourages long-term discipline.

Tips to Maximise Your PPF Returns

Deposit before the 5th of the month (ideally early April) so that the full amount earns interest for the entire year. Avoid missing the minimum ₹500 deposit in any year, as the account becomes inactive and certain facilities are suspended until reactivation. If you have an existing balance, continue regular contributions rather than treating the account as dormant. Consider opening a separate PPF account for a minor child (the combined limit of parent + child is still ₹1.5 lakh for 80C purposes in the parent’s hands, but the child’s account grows independently). Finally, review the interest rate announcement every quarter so you remain aware of any changes, even though the rate has been stable for several years.

PPF vs Other Popular Savings Options

Compared with bank fixed deposits, PPF generally offers a higher post-tax return because of its tax-free status and sovereign guarantee. Against equity-oriented instruments such as ELSS or NPS Tier-I, PPF provides capital protection and predictable growth at the cost of lower long-term expected returns. Many investors therefore use PPF as the debt or safety portion of their overall portfolio while allocating growth-oriented money to equities. The ideal mix depends on your age, risk tolerance, and existing asset allocation.

Who Should Consider Investing in PPF?

PPF suits risk-averse investors who value capital safety and tax efficiency. It is particularly useful for those still under the old tax regime who can claim the full 80C deduction. Parents often open accounts for children to create an education or marriage corpus. Self-employed individuals who do not have access to EPF find PPF a convenient way to build a retirement-oriented nest egg. Even high-income earners who have exhausted other 80C options frequently use PPF for its tax-free compounding.

Limitations to Keep in Mind

The 15-year lock-in reduces liquidity. Although partial withdrawals and loans are available, they are restricted. The interest rate, while currently attractive, is not guaranteed to remain at 7.1% forever; future quarterly reviews could raise or lower it. The annual deposit ceiling of ₹1.5 lakh limits how much you can park in the scheme. Finally, under the new tax regime the 80C deduction is not available, so the relative attractiveness of PPF depends on your overall tax situation.

Final Thoughts

The Public Provident Fund continues to be a cornerstone of long-term financial planning for millions of Indians because it combines safety, reasonable returns, and unmatched tax efficiency. A clear, accurate PPF calculator turns the abstract idea of “saving every year” into concrete future numbers you can plan around. Enter your intended annual deposit, any existing balance, and the desired tenure, then review the maturity amount and year-wise growth. Use the insights to decide how PPF fits into your broader savings and investment strategy. Consistency over 15 years or more, combined with the power of tax-free compounding, can create a meaningful corpus that supports important life goals.
