PPF Calculator - Public Provident Fund Calculator

PPF Maturity Amount

What is a PPF calculator?

A Public Provident Fund (PPF) calculator is an online long-term investment tool designed to help investors calculate the potential returns and growth of their investments in a PPF account.

It considers various factors such as the contribution amount, interest rate, and investment duration to estimate the maturity amount and the interest earned over a period. 

If you are someone who is planning to invest in PPF and not sure how much to invest or how much returns you may get on investing a certain amount, our PPF calculator is here for you. 

By using a PPF calculator, you gain a clear understanding of the future value of their PPF investments, make informed financial decisions, and effectively plan their savings.

Once you decide the amount you can afford to invest on a regular basis, the calculator considers the tenure to be 15 years and the prevalent interest rate to calculate the returns. 

However, ensure that you make your PPF investments before the 5th of the month, or else you will not receive the interest for that month. This is because the PPF interest is calculated on the lowest balance between the close of the 5th day and the last day of every month. 

Thus, a PPF contribution made on the 5th of a month will be taken into consideration for interest calcultion and will earn interest for that month, while any PPF contribution made after the 5th of the month will not earn interest and result in a loss of interest for that month. 

Why use a PPF calculator?

Here’s why you should use a PPF calculator:

Plan your investments: It helps you visualise how your PPF grows, thus helping you plan your contributions to reach desired financial goals, which could be building a retirement corpus, children’s education, marriage, etc.

Compare investment options: You can compare PPF returns with other options, such as bank deposits, helping you make informed financial decisions.

Maximise your contributions: It will help you effectively utilise the full Rs.1.5 lakh annual limit by understanding how different contribution frequencies impact returns.

Track your progress: You can monitor your PPF’s growth over a period, keeping you motivated enough to remain on track to meet your financial goals.

How to use PPF Calculator?

You can follow the easy steps mentioned below to use the PPF calculator to calculate your PPF investments accurately:

Select the frequency of investment: The frequency of your investment will influence your maturity value. Ideally, select monthly in case you are salaried for more convenient investment and accurate results.

Enter the monthly PPF investment: It is the amount you wish to invest in the PPF account. You could input a monthly, quarterly, semi-annual, or annual amount. Also, ensure that your investment amount is not more than Rs 12,500 per month or Rs 1.5 lakh a year.

Select the duration of investment:  It is the time you will continue your PPF investment. The minimum time available is 15 years, and you have the option to extend the term in batches of five years after that. The PPF calculator assumes that you will be investing the same amount till the time of maturity.

Check the future value:  Once you enter all the above details, our calculator will automatically show the maturity amount. 

How the PPF Calculator Can Help You?

The PPF calculator makes it easy for an investor to keep track of their account balance and growth. It can also aid in resolving your queries regarding changing interest rates or how they affect your maturity value.

The online tool accurately calculates your potential profit and shows you the data within a short span of a few seconds.

You are only required to provide few basic information such as deposit amount, tenure and investment frequency. After this, you can automatically see the current PPF interest rate on the calculator. This makes the PPF calculations quick and easy to use for anyone.

Formula used for calculating PPF

A PPF calculator uses a similar formula that’s used for calculating the future of an annuity. Simply put, it calculates the future value of your investment, depending on the annual contribution you make towards the PPF and the prevailing interest rate. 

The calculation formula that a PPF calculator uses is as follows:

M = P [ ( { (1 + i) ^ n } - 1 ) / i ] 

In which:

M = Maturity benefit

P = Annual installments

i = Interest rate

n = Number of years

The part after the P in the formula is the annuity factor, which when multiplied with the annual contribution, provides the maturity value of the PPF investment. 


Let’s say, you make annual contributions of Rs 1,00,000 for 15 years and the PPF account interest rate is 7.1%.

By using the above-mentioned PPF calculation formula:

M= Rs 1,00,000 [({(1+0.071)^15}-1)/i] = Rs 27,12,139

PPF calculator example table

The concept of the power of compounding and how it works in favour of an investor when it comes to PPF calculation could be explained with the following table, which highlights the PPF interest earned, the principal invested and the PPF maturity value for 15, 20, and 30 year tenures.

Rs 66,58,288

30 years

Rs 1.5 lakh

Rs 1,09,50,911

Rs 1,54,50,911

In this PPF calculation example, it is assumed that the annual investment amount is Rs 1,50,000, and the PPF interest rate is 7.1% per annum (the current PPF interest rate is 7.1% for Q4 of FY 2023-24). 

The above example highlights the power of compounding when investing in PPF – your maturity amount rises from Rs 40 lakh to Rs 1 crore merely by investing Rs. 1.5 lakh over a 15-year period to a 30-year period.

Frequently Asked Questions

How accurate are PPF calculators?

A PPF calculator aids an investor in identifying the estimated returns receivable at the policy tenure end based on the current interest rates. Interest rates on PPF are known to keep on changing every quarter, and, therefore, results at the end are likely to vary from the calculated returns.

Can I transfer my PPF account to another branch or office?

Yes, you can transfer the PPF account from a particular branch to another branch or office. 

How much interest rate can I get on my PPF account?

The PPF interest rate has been unchanged since April 2020 and ranges to 7.1%

When is my investment going to mature?

A PPF account matures after 15 years from the end of the financial year of opening. For example, in case you opened the account between April 1, 2022 and March 31, 2023. From the immediate next financial year, the actual tenure starts for maturity calculation, which means from April 1, 2023. The 15-year tenure of PPF is April 1, 2023, plus 15 years, so the PPF will mature on April 1, 2038.

What factors does a PPF calculator consider?

A PPF calculator takes into account factors such as contribution amount, investment duration and prevailing interest rate. The PPF calculator provides an estimated projection of the maturity amount and total earned interest from your PPF investment.

What are some examples of how to use a PPF calculator?

The standard formula to calculate PPF is mentioned as below with an example.

An investor can contribute a minimum of Rs 500 and a maximum of Rs 1.5 lakh in a financial year. Contributions can only be undertaken once a month.

For instance, if a person invests Rs 50,000 every year in PPF, they can build a corpus of Rs 13.56 lakh in 15 years. This is calculated at the current interest rate of 7.1%.

Investing the maximum amount of Rs 1.5 lakh every year in a PPF account would build a corpus of Rs 40.68 lakh in 15 years.

At the same time, opting for extensions, with or without contributions, can further lead to a rise in the maturity amount.

Where can I find a PPF calculator?

An individual can easily calculate the PPF interest and, thus, the maturity amount for a particular tenure with the aid of online PPF calculators. A number of PPF calculators are available online and can be used for this purpose. They are free of cost and quite easy to use.

How often should I use a PPF calculator?

As there is no limit to how many times you can use the PPF calculator, you can try out different investment amounts and frequencies multiple times. This will help you in figuring out how much to invest to get your desired return.
