What is PPF (Public Provident Fund)?
The Public Provident Fund (PPF) is a long-term savings scheme backed by the Government of India, offering guaranteed returns with complete tax benefits. Launched in 1968, PPF has become one of the most popular investment options for Indian citizens seeking safe, tax-free returns.
PPF combines the benefits of tax savings under Section 80C, tax-free interest, and tax-free maturity proceeds, making it an EEE (Exempt-Exempt-Exempt) investment. With a 15-year lock-in period that can be extended in blocks of 5 years, PPF is ideal for long-term wealth creation and retirement planning.

Understanding the PPF Formula
PPF returns are calculated using the future value of an annuity formula:
Where:
- FV = Future Value (Maturity Amount)
- P = Annual deposit amount
- r = Annual interest rate (currently 7.1%)
- n = Number of years
PPF Investment Rules and Limits
Contribution Limits
The minimum annual investment in PPF is ₹500, while the maximum is ₹1,50,000 per financial year. You can make deposits in lump sum or up to 12 installments per year. Exceeding the ₹1.5 lakh limit does not earn interest on the excess amount.
Lock-in Period
PPF has a mandatory 15-year lock-in period from the end of the financial year in which the account was opened. After maturity, you can extend the account in blocks of 5 years, with or without making fresh contributions.
Withdrawal Rules
Partial withdrawals are allowed from the 7th year onwards, up to 50% of the balance at the end of the 4th preceding year. Premature closure is permitted after 5 years only in specific cases like serious illness or higher education, with a 1% interest penalty.
Tax Benefits of PPF
PPF offers triple tax benefits (EEE status):
- Tax Deduction: Contributions up to ₹1.5 lakh qualify for deduction under Section 80C
- Tax-Free Interest: Interest earned is completely tax-free
- Tax-Free Maturity: The maturity amount is exempt from tax
PPF vs Other Investment Options
PPF vs Fixed Deposit
While FDs offer liquidity, PPF provides better post-tax returns due to tax-free interest. PPF is ideal for long-term goals, while FDs suit short-term needs.
PPF vs National Savings Certificate (NSC)
Both offer Section 80C benefits, but PPF interest is tax-free while NSC interest is taxable. PPF has a longer lock-in (15 years vs 5 years for NSC).
PPF vs Mutual Fund SIP
PPF offers guaranteed returns with zero risk, while SIPs can provide higher returns but with market risk. A balanced portfolio often includes both.
