Enter your annual deposit and interest rate to estimate the maturity value and total interest after 15 years.
⚠️ This calculator provides an estimate based on India's government/financial schemes using publicly available 2026 rates. Actual amounts may differ due to scheme changes or individual circumstances — please verify with an official source or financial advisor.
The Public Provident Fund (PPF) is a long-term Indian government-backed savings scheme known for its EEE tax status (contributions, interest, and withdrawals are all tax-exempt) and stable interest rate. You can deposit between ₹500 and ₹1,50,000 per year, with interest compounded annually. The standard maturity period is 15 years, extendable in 5-year blocks afterward. The rate for the Jul-Sep 2026 quarter is 7.1%, as announced quarterly by India's Ministry of Finance.

How the Maturity Value Is Calculated
This calculator assumes a deposit at the start of each financial year (earning a full year of interest on that year's deposit) and compounds annually over 15 years. For example, depositing ₹1,50,000 per year for 15 years at 7.1% yields a maturity value of roughly ₹40.68 lakh (₹22.5 lakh invested + about ₹18.18 lakh interest). In practice, PPF interest is calculated on the lowest monthly balance between the 5th and end of month, so real-world results may differ slightly.
Frequently asked questions
How often does the PPF rate change?
India's Ministry of Finance announces small savings scheme rates every quarter (3 months), including PPF. For Jul-Sep 2026 it is 7.1%, unchanged for 9 consecutive quarters since April 2020.
What is the maximum annual deposit?
You can deposit up to ₹1,50,000 per year; any amount above that earns no interest. The minimum annual deposit is ₹500.
Can I extend PPF after the 15-year maturity?
Yes, PPF accounts can be extended indefinitely in blocks of 5 years, with or without further contributions. This calculator only covers the base 15-year scenario, so extensions must be calculated separately.
