Introduction

A PPF (Public Provident Fund) is a safe, government-backed savings plan in India. It helps you grow your money over time with tax-free returns. The interest rate is set by the Government of India each quarter, and right now it is 7.1% per year. You must keep your money locked in for at least 15 years, but you can extend it in blocks of 5 years after that. The most you can put in each year is ₹1,50,000.

This PPF Calculator helps you see how much your savings will grow. Just enter how much you want to invest, how often you want to invest, and how many years you plan to save. The tool will show you your total invested amount, the interest you earn, and your final maturity value. It also gives you a clear chart and a year-by-year table so you can track your money at every step. Use it to plan your long-term savings and make smart choices with your hard-earned money.

How to Use Our PPF Calculator

Enter a few details about your Public Provident Fund investment below. The calculator will instantly show your maturity value, total interest earned, and a year-by-year breakdown.

Investment Frequency: Pick how often you plan to deposit money — monthly, quarterly, half-yearly, or yearly. This changes the deposit cap to stay within the ₹1,50,000 annual PPF limit.

Investment Amount: Type in the amount you want to invest each period. The minimum is ₹500 and the maximum depends on the frequency you chose. You can also drag the slider to adjust the amount.

Investment Duration: Set how many years you will keep investing. PPF has a 15-year lock-in period, so the minimum is 15 years. You can extend it up to 50 years using the plus and minus buttons or the slider.

Rate of Interest: The current PPF interest rate of 7.1% is filled in by default. You can change it to test different scenarios. The rate can be set between 1% and 15%.

What Is a PPF Calculator?

A PPF calculator helps you find out how much money you will get when your Public Provident Fund account matures. You enter how much you invest, for how many years, and the interest rate. The calculator then shows your total invested amount, total interest earned, and the final maturity value. If you want to compare how your PPF returns stack up against other savings options, try our Compound Interest Calculator to see the difference compounding makes across various instruments.

What Is PPF?

PPF stands for Public Provident Fund. It is a savings scheme run by the Government of India. It is one of the safest ways to save money because the government backs it. The money you put in, the interest you earn, and the amount you get back at maturity are all tax-free under Section 80C of the Income Tax Act. This makes PPF an EEE (Exempt-Exempt-Exempt) investment. To understand how your overall financial health looks alongside your PPF savings, you can use our Net Worth Calculator.

Key Rules of PPF

  • Lock-in period: 15 years. You cannot take out all your money before 15 years are over.
  • Minimum deposit: ₹500 per year.
  • Maximum deposit: ₹1,50,000 per year. You cannot invest more than this in one financial year.
  • Interest rate: The government sets the rate every quarter. As of now, it is 7.1% per annum.
  • Compounding: Interest is compounded once a year (annually). To learn more about how annual versus other compounding frequencies affect your returns, check out our APY Calculator.
  • Extension: After 15 years, you can extend your PPF in blocks of 5 years as many times as you want.
  • Partial withdrawal: Allowed from the 7th year onward, with limits.
  • Loan facility: You can take a loan against your PPF balance from the 3rd year to the 6th year.

How PPF Interest Is Calculated

PPF interest is calculated on the lowest balance between the 5th and the last day of each month. This means if you deposit your money before the 5th of the month, it earns interest for that month. The interest is added to your account at the end of each financial year (March 31). To get the most interest, always invest before April 5 each year if you make a yearly deposit. If you are curious about the difference between compound and simple interest, our calculator can help you compare both approaches side by side.

Who Should Invest in PPF?

PPF is a good choice for people who want a safe, long-term savings plan with guaranteed returns and full tax benefits. It works well for salaried individuals, self-employed people, and anyone who wants to build a retirement fund without taking any risk. Since the returns are fixed by the government and not linked to the stock market, your money stays protected from market ups and downs.

If you are planning for retirement, consider using our Retirement Calculator to map out your complete financial picture. You can also explore a SIP Calculator to see how systematic investments in mutual funds compare to PPF returns. For those looking to understand how much their money will be worth in the future at different rates, our Future Value Calculator is a great companion tool. And if you want to see how rising prices might erode your PPF maturity value over time, the Inflation Calculator can help you gauge the real purchasing power of your savings.

To build a well-rounded savings strategy, you might also want to set aside an emergency fund alongside your PPF account. If you are comparing PPF with other fixed-return options such as bank fixed deposits, our CD Calculator can help you weigh the returns. Additionally, tools like the Savings Calculator and the Investment Calculator can give you a broader view of how different saving and investing habits shape your financial future. For a quick estimate of how long it takes your PPF balance to double at a given rate, try the Rule of 72 Calculator. You can also use our Income Tax Calculator to see how your Section 80C deduction from PPF contributions lowers your tax liability, and the Interest Calculator to run quick interest comparisons across different scenarios.


Frequently asked questions

How does this PPF Calculator find the maturity value?

The calculator takes your investment amount, multiplies it by how many times you pay each year, and adds that to your balance every year. It then applies the interest rate on the total of your opening balance plus that year's contribution. Interest is compounded once a year. This repeats for every year of your chosen duration to give you the final maturity value.

Why does the maximum deposit amount change when I switch frequency?

PPF has a strict annual limit of ₹1,50,000. When you pick monthly, the cap per deposit becomes ₹12,500 (₹1,50,000 ÷ 12). For quarterly it is ₹37,500, for half-yearly it is ₹75,000, and for yearly it stays at ₹1,50,000. The calculator adjusts automatically so you never exceed the annual limit.

Can I invest less than ₹500 in PPF?

No. The minimum deposit allowed in a PPF account is ₹500 per year. This is a rule set by the government. The calculator will show an error if you enter anything below ₹500.

Why is the minimum duration set to 15 years?

PPF has a mandatory lock-in period of 15 years. You cannot withdraw your full balance before that. The calculator enforces this rule so your results always match real PPF conditions.

What happens after 15 years? Can I keep investing?

Yes. After 15 years, you can extend your PPF account in blocks of 5 years. There is no limit on how many times you extend. This calculator lets you set a duration up to 50 years to plan for long-term growth.

Is the interest rate fixed for the entire duration?

In real life, the government revises the PPF interest rate every quarter, so it can change. This calculator uses a single rate for the entire duration to give you an estimate. You can change the rate to test different scenarios and see how it affects your maturity value.

Are PPF returns really tax-free?

Yes. PPF falls under the EEE (Exempt-Exempt-Exempt) category. The money you invest (up to ₹1,50,000) gets a tax deduction under Section 80C. The interest you earn is not taxed. The maturity amount you receive is also fully tax-free.

What does the year-by-year table show?

The table shows five things for each year: the opening balance, the amount you invested that year, the interest earned that year, and the closing balance. It helps you track exactly how your money grows over time.

Does it matter when I deposit money during the year?

Yes, in a real PPF account it matters a lot. Interest is calculated on the lowest balance between the 5th and last day of each month. To earn the most interest, deposit your money before the 5th of the month. For yearly deposits, invest before April 5. This calculator assumes the full annual contribution earns interest for the entire year.

Can I change the interest rate to something other than 7.1%?

Yes. The default rate is 7.1% because that is the current government rate. But you can change it to any value between 1% and 15%. This is useful if you want to see how a rate increase or decrease would affect your final amount.

What do the two charts show?

The growth chart shows how your total balance and total invested amount rise each year. The gap between the two lines is your interest. The donut chart shows the split between how much you put in and how much interest you earned, as a percentage of the maturity value.

Can two people in a family both have PPF accounts?

Yes. Each person can open one PPF account in their own name. A parent can also open one account for each minor child. However, the combined deposit for a parent's own account and a minor child's account cannot exceed ₹1,50,000 per year.

What if I miss a deposit in one year?

If you do not deposit at least ₹500 in a financial year, your PPF account becomes inactive. You can reactivate it by paying ₹500 for each missed year plus a ₹50 penalty per missed year. This calculator assumes you invest every year without a gap.

Can I withdraw money before 15 years?

Partial withdrawals are allowed starting from the 7th financial year. You can withdraw up to 50% of the balance at the end of the 4th year or the year before withdrawal, whichever is lower. Full withdrawal before 15 years is not allowed except in special cases like serious illness.

How accurate are the results from this calculator?

The results are close estimates based on annual compounding at a fixed rate. In real life, the PPF rate can change every quarter, and interest depends on your exact deposit dates each month. Use these results for planning, not as an exact guarantee.
