What is PPF calculator?

A PPF calculator is a financial tool that helps you estimate the maturity amount and returns on your investments in a Public Provident Fund (PPF) account. You input details such as the amount you plan to invest, the duration of investment, and the interest rate, and the calculator computes the future value of your investment. It helps you plan your savings and financial goals by providing insights into your PPF investments.

How is PPF interest calculated?

The interest on a Public Provident Fund(PPF) account is calculated using the formula for compound interest. Here's how it works:

The formula for compound interest is:

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


i : Rate of interest

F: Maturity value

N: Total number of compounding periods(usually years).

P: Annual instalments

Suppose you start a PPF account where you deposit Rs. 10,000 annually for 15 years. The annual interest rate is 7.5%.We want to find out the total amount in the PPF account at the end of 15 years.

P=Rs.10, 000 (annual instalments)

i=7.5% (annual interest rate)

N=15 (total number of years)

Using the formula:

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

F = 10,000 * [({(1+ 0.075) ^15}-1)/ 0.075] = ₹393,200.

Calculating the expression within the brackets first:

{(1+ 0.075)^15} = 3.949

[3.949-1/0.075]= 39.32

Now, substituting it back into the formula:

F= 10,000* 39.32

F= Rs.393,200

So, the total amount in your PPF account at the end of 15 years would be Rs. 393,200.
