How Public Provident Fund (PPF) Interest & Maturity Work
The Public Provident Fund (PPF) is a sovereign-backed long-term savings instrument in India offering government capital security and triple tax exemption (EEE). Knowing how the 5th-of-the-month calculation rule works allows investors to maximize cumulative compounding returns over the 15-year tenure.
Calculations default to the officially notified rate of 7.1% per annum. Rates for government small savings schemes are reviewed and notified quarterly by the Ministry of Finance, Government of India.
Interest is computed monthly on the lowest balance recorded between the 5th and the end of each calendar month. Deposits made on or before the 5th earn interest for that entire calendar month.
Monthly accrued interest is credited to your PPF account once each year at the close of the financial year (March 31st), compounding into the opening principal for the following year.
Worked PPF Example: Maximum ₹1.5 Lakh Annual Contribution (15 Years at 7.1%)
Suppose an investor deposits the statutory maximum of ₹1,50,000 every year in April for the full 15-year tenure:
Total Amount Deposited (15 Years): ₹22,50,000
Total Interest Earned: ₹18,18,209
Total Tax-Free Maturity Value: ₹40,68,209
Wealth Multiplier: 1.81x your invested capital, completely free of income tax.
Rules and notified rates are verified against official directives from theDepartment of Economic Affairs, Ministry of Finance and India Post Small Savings Scheme schedules.

Frequently Asked Questions
What is the maximum amount I can deposit in a PPF account each year?
The statutory maximum limit for deposits in a Public Provident Fund account is ₹1,50,000 per financial year. Deposits exceeding this limit do not earn interest and are not eligible for tax benefits.
How is monthly interest calculated on PPF deposits?
Interest is calculated monthly on the lowest balance in the account between the close of the 5th day and the end of the month. To maximize monthly interest, deposits should be credited on or before the 5th of each month.
Can the PPF interest rate change during my 15-year tenure?
Yes. The Ministry of Finance notifies small savings scheme interest rates quarterly. While the current rate is 7.1% p.a., it may be adjusted up or down in subsequent quarters.
Can I extend my PPF account beyond the 15-year maturity?
Yes. You can extend your PPF account indefinitely in blocks of 5 years, with or without making further annual contributions.
Is PPF maturity interest completely tax-free?
Yes. PPF operates under the Exempt-Exempt-Exempt (EEE) tax regime in India: contributions qualify for Section 80C deductions (Old Regime), interest earned is tax-exempt, and the entire maturity proceeds are exempt from income tax.
