PPF Calculator
Calculate your PPF (Public Provident Fund) maturity value, total interest earned and year-wise growth with this online calculator for India.
How is PPF Maturity Value Calculated?
PPF (Public Provident Fund) compounds interest annually. This calculator uses the standard deposit-at-start-of-year model: each year's opening balance plus that year's deposit earns a full year of interest, and the resulting closing balance becomes next year's opening balance.
Balancen = (Balancen−1 + Yearly Deposit) × (1 + Rate)
For example, depositing ₹1,50,000 every year at 7.1% for 15 years grows to a maturity value of about ₹40.68 lakh — of which ₹22.5 lakh is your own investment and the rest is interest earned.
Frequently Asked Questions
What is the PPF lock-in period?
A PPF account has a 15-year lock-in period. After maturity, it can be extended indefinitely in blocks of 5 years, with or without making further contributions.
Is PPF interest taxable?

What is the minimum and maximum PPF deposit?
You must deposit at least ₹500 per year to keep a PPF account active, and can deposit up to ₹1,50,000 per year, which also qualifies for tax deduction under Section 80C.
