How the PPF Calculator (Public Provident Fund Maturity) works
PPF pays interest yearly, compounded annually, on the lowest balance between the 5th and the last day of each month. Depositing before 5 April each year earns interest for the whole year, which this calculator assumes.
The account matures after 15 full financial years and can be extended in blocks of 5 years. Deposits qualify for the section 80C deduction in the old tax regime, and interest and maturity are tax-free.
The formula
Worked example

- ₹1,50,000 a year for 15 years at 7.1% matures at ₹40,68,209.
