PPF Calculator

What is a PPF Calculator?

A PPF Calculator helps you estimate the maturity value, total investment, and interest earned from your Public Provident Fund (PPF) account. By entering your yearly investment amount, current interest rate, and investment period, the calculator provides an instant estimate of how your savings will grow over time.

The Public Provident Fund is a government-backed savings scheme in India that offers tax benefits, guaranteed returns, and long-term wealth creation. Using a PPF calculator allows you to plan your investments effectively and understand the potential returns on your contributions.

How Does a PPF Calculator Work?

A PPF calculator works by using the current PPF interest rate and annual contributions to compute the maturity amount.

When you enter:

• Annual investment amount

• Investment duration (usually 15 years)

• Interest rate

the calculator estimates:

• Total invested amount

• Total interest earned

• Final maturity value

Since the PPF interest is compounded annually, your investment grows every year with accumulated interest.

PPF Calculation Formula

The maturity value of a PPF investment is calculated using a compound interest formula.

Formula:

F = P × [((1 + r)^n − 1) / r]

Where:

• F = Maturity amount

• P = Annual investment

• r = Interest rate

• n = Investment period in years

This formula helps determine how your yearly deposits grow with compound interest over time.

Example of PPF Calculation

Suppose you invest ₹1,50,000 every year in a PPF account with an interest rate of 7.1% for 15 years.

Using a PPF calculator helps you quickly estimate these values without manual calculations.
