Public Provident Fund (PPF)

What is PPF?

PPF is one of the most popular long-term investment options among investors because it not only diversifies your portfolio but also helps you save tax.

The tenure of PPF is 15 years (including lock-in), and after maturity, it can be extended in 5-year blocks with or without contributions or closed. In a Public Provident Fund (PPF), you can invest a minimum of ₹500 and a maximum of ₹1.5 lakh in a financial year.

Public Provident Fund (PPF), launched in 1968 by the National Savings Institute under the Ministry of Finance, is a long-term investment scheme backed by the Government of India. To invest, one must open a PPF account, and the amount deposited in a financial year can be claimed as a deduction under Section 80C.

A court may issue an order or decree to attach a person’s property or assets for any debt or liability they have incurred, even if that person holds a PPF account. However, such an order has no effect on the PPF account. According to the rules, the PPF account is safeguarded, and its balance cannot be seized or attached, even by a court order.

Formula for PPF Maturity

The PPF maturity is calculated using the formula:

M = P × ((1 + r)n − 1) / r
  • M = Maturity Amount
  • P = Annual Investment
  • r = Annual Interest Rate (in decimal)
  • n = Number of Years

How Does PPF Work?

Here’s the basic flow:

  • Investment Amount – You choose how much to invest annually (within limits).
  • Interest Rate – Declared by the government every quarter (e.g., 7.1% per annum).
  • Tenure – 15 years (can be extended in blocks of 5 years).
  • Compounding – Interest is compounded annually, meaning your money grows faster over time.

Example

Suppose you open a PPF account and deposit ₹1,00,000 every year for 15 years. Let’s assume the interest rate is 7.1% per annum, compounded annually.

  • Total amount you invest: ₹15,00,000 (₹1 lakh × 15 years)
  • Total interest earned: Around ₹12,12,139
  • Maturity amount at the end of 15 years: ₹27,12,139 (investment + interest)

This means your money almost doubles in 15 years, plus you don’t pay any tax on the interest or maturity amount.

Benefits of PPF

  • Tax saving – The amount you invest in PPF can be claimed as a deduction of up to ₹1.5 lakh under Section 80C, helping you reduce your taxable income.
  • Long-term savings discipline – With a 15-year lock-in period it helps you build a long-term savings habit and grow wealth steadily.
  • Safe and government backed – PPF is supported by the Indian Government, which makes it one of the safest investment options.
  • Attractive returns – The interest rate is declared by the government every quarter and is usually higher than most bank fixed deposits.
