What is a PPF account?

The Public Provident Fund, or PPF, is an initiative by the Indian government to encourage small investors to make long-term investments. The scheme was introduced in 1968.

How to invest in PPF? You can open a PPF account at any authorized bank or Post Office and start investing with as little as Rs. 500 per year. To promote long-term investment, this scheme comes with a lock-in period of 15 years.

The PPF scheme offers attractive interest rates and tax benefits. Investors can use this scheme to get guaranteed risk-free returns and build a retirement corpus. After learning what the Public Provident Fund is, let's see how to estimate its return.

How to calculate PPF return?

To find the return on PPF investment in our PPF account calculator, we use the following formula:

FV=P((1+r)n1r)(1+r)\small FV = P \left ( \frac{(1+r)^n - 1}{r} \right ) (1+r)


  • FVFV - Future value of your investment, or its maturity value;
  • PP - Annual installments;
  • nn - Number of years the investment if for; and
  • rr - Rate of interest.

To further understand it, let us imagine that you invest Rs. 1.5 lakh for 15 years and the annual rate of interest is 7.1%.

  • As you are making yearly payments, the total investment made in 15 years is:
Total investment=15×1,50,000=Rs. 22,50,000\quad \quad \scriptsize \begin{split} \rm Total\ investment &= 15 \times 1,50,000\\ & = \rm Rs.\ 22,50,000 \end{split}
  • The maturity value of your investment will be:
FV=1,50,000×(1+0.071)1510.071×(1+0.071)FV=Rs. 40,68,209\quad \quad \scriptsize \begin{split} FV &= 1,50,000 \\ &\times \frac{{(1 + 0.071)^{15} - 1}}{ 0.071} \times (1 + 0.071) \\ FV &= \rm Rs.\ 40,68,209 \end{split}
  • You can calculate the total interest earned as:
interest=40,68,20922,50,000=Rs. 18,18,209\quad \quad \scriptsize \begin{split} \rm interest &= 40,68,209 - 22,50,000 \\ &= \rm Rs.\ 18,18,209 \end{split}

Does that sound complicated? It shouldn't be with our tool! You can use the PPF calculator for monthly deposits or any other frequencies to quickly assess the final balance of your investment.

How to use the PPF interest calculator?

Now let us see how we can use the PPF interest calculator to estimate the return of your PPF investments under the same conditions as above (which we put into brackets):

PPF inputs

  1. Choose your preferred deposit frequency (Yearly) and provide the deposit amount (Rs. 1,50,000).

  2. Input the annual interest rate (7.1%).

  3. Enter the tenure of your planned investment, i.e., 15 years. You can also set the date when you plan to start your investment.

  4. Our PPF calculator also has the option of giving inflation-adjusted returns. For the sake of simplicity, we will set it to 0%.


  1. The calculator will display the final balance (Rs. 40,68,209) of your PPF account. It will also give a summary of your investment, i.e., payments made by you (Rs. 22,50,000) and the total returns earned on your investment (Rs. 18,18,209).

  2. Finally, you can find a detailed account of your capital growth over the years in the form of a chart of balances and a table of payment schedules.

What's more, we added the ability for you to determine the periodic investments you need to make to reach a specific target amount. For example, use the PPF calculator for monthly depositions determination.

How to open a PPF account?

Any Indian citizen can open a PPF account by visiting either a Post Office or any authorized bank branch and submitting the following documents:

  • Filled PPF account opening application form;
  • Address and identity proof; and
  • Cheque for the first deposit amount.

Some banks also allow you to open a PPF account online without visiting the bank branch office. Be sure to check PPF rules that each specific bank enforces.

Interest rate on PPF

The PPF interest rate is set by the Ministry of Finance each year. The interest rate on a PPF account was 7.1% in 2021.

The interest is calculated on the lowest balance between the end of the fifth day and the last day of the month. Therefore, to maximize your PPF investment return, you should try to pay your periodic deposit before the 5th day of the month.

What are the benefits of a PPF account?

Some benefits of a PPF account are:

  • Tax benefits - The deposits made into a PPF account qualify for tax deduction under Sec.80-C of the Income Tax Act. The interest earned is also free from income tax under Section-10 of the I.T. Act.

  • Safe investment option - The Government of India manages the PPF scheme. Hence it is a safer option than mutual fund schemes. The most crucial benefit of a PPF account is that its balance can't be attached under any order or decree of a court of law regarding any debt or liability incurred by the account holder.

  • Attractive interest rates - The PPF scheme offers higher interest rates than other investment options, such as fixed deposit, recurring deposit, or Post Office monthly income scheme. You can compare the returns from these schemes using the FD calculator, RD calculator, and the post office monthly income scheme calculator.

  • Transferable - You can easily transfer your PPF account from one bank to another without breaking any specific PPF withdrawal rules.

  • Facility to avail loan - You can avail a loan against your PPF account from the 2nd financial year up to the 6th financial year.

Other important PPF rules

Some other important points to keep in mind while opening a PPF account are:

  • Minimum contribution - If you fail to deposit a minimum of Rs. 500 in the PPF account during a financial year, the account will be treated as discontinued. To revive a discontinued account, you need to pay a penalty of Rs. 50 along with arrears of the minimum deposit amount (Rs. 500) for each year of default.

  • PPF lock-in period - All PPF accounts have a lock-in period of 15 years during which you can not close the account except under certain conditions, e.g., death of account holder, change of residency status, etc.

  • PPF withdrawal rules - You can withdraw up to 50% of your account balance after the ending of the 5th financial year.

  • Extension of account after maturity - After the maturity of your scheme, i.e., 15 years, you can choose to continue your account with or without making any further contributions.

  • Joint account - You can not open a joint account under this scheme.
