What is PPF?
Public Provident Fund (PPF) is a long-term government-backed savings scheme with a 15-year lock-in period. It offers tax-free returns under Section 80C and interest is compounded annually.
How is PPF interest calculated?
Interest is computed on the lowest balance between the 5th and last day of each month, and credited annually at the end of the financial year. Deposits made before the 5th earn interest for that month.
Can I extend my PPF account?
Yes. After the 15-year maturity, you can extend in blocks of 5 years any number of times, with or without further contributions. This calculator supports extensions up to 50 years.
What are the tax benefits?
PPF follows the EEE (Exempt-Exempt-Exempt) model — contributions are deductible under 80C (up to ₹1.5L), interest earned is tax-free, and the maturity amount is completely tax-free.
