Public Provident Fund: Meaning, Benefits, and How It Works

The Public Provident Fund (PPF) is one of the most popular long-term savings schemes in India. It is backed by the government and offers safe investment, attractive interest rates, and tax benefits.

What is Public Provident Fund (PPF)?

The Public Provident Fund is a government-supported savings scheme introduced to promote long-term financial security and disciplined savings.

The scheme has a lock-in period of 15 years and allows investors to deposit money annually while earning compound interest.

Many investors also compare PPF with other savings tools such as Fixed Deposit and Recurring Deposit before making investment decisions.

How Public Provident Fund Works

Investors open a PPF account with a bank or post office and deposit money every year. The minimum annual deposit is ₹500 and the maximum allowed investment is ₹1.5 lakh.

The interest rate is determined by the government and compounded annually. Because of this compounding effect, long-term investments in PPF can grow significantly over time.

PPF Calculation Formula

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

PPF Formula:

F = P × ( ( (1 + i)ⁿ − 1 ) / i )

Where:

• F = Final maturity amount
• P = Annual investment amount
• i = Annual interest rate
• n = Number of years

This formula helps calculate the total maturity value of your PPF account based on yearly contributions and compound interest.
