Public Provident Fund (PPF) Calculator

What is a PPF?

Public Provident Fund (PPF) is a long-term investment scheme mandated by the government of India.

Since it is backed by the government of India, it guarantees a low risk and a stable return.

Investment in a PPF scheme can start for as low as Rs.500 annually to a maximum of Rs.1.5 Lakh annually. Investor is eligible to make deposits in 1 to 12 yearly installments.

PPF scheme has a lock-in period of 15 years. Upon maturity, Investors have an option to extend this scheme by a lock-in period of 5 years.

Investments made under this scheme are completely exempted from wealth tax. 

How is interest in PPF calculated?

As per revised interest rate (April 2020) on PPF, a compound interest of 7.1% is applicable on total account balance before 5th day of each month.

For deposits made after 5th day of the month, interest earned will remain same as of previous month.

For maximum benefit of this scheme, it is recommended to deposit complete annual amount at the start of financial year i.e. before 5th of April each year.

PPF calculation formula:

A= P x [(1+ r)^t / r] x (1+r)


A= Maturity amount.

P= Principal amount.

r= Rate of Interest.

t= Tenure in years.

Let’s consider an example to understand this better,

You are investing a principal amount of 10000 annually for PPF scheme at current interest rate of 7.1%.

A= 10000 x [(1+ 0.071)^15 / 0.071] x (1+0.071)

A= 271,213.95

Maturity amount in this case at the end of lock-in period of 15 years will be 271,213.95.
