About the PPF Calculator
A PPF calculator shows what your Public Provident Fund grows to. PPF pays 7.1% a year (October–December 2026), compounded yearly, and matures after 15 years. Depositing the maximum ₹1,50,000 every year builds ₹40,68,209, all of it tax-free.
How it is calculated
Balance at year end = (previous balance + this year’s deposit) × (1 + r)
- r is the PPF interest rate as a decimal. The government reviews it every quarter.
- The calculator assumes you deposit by 5 April each year, so the deposit earns interest for the full year.
- Interest is calculated monthly on the lowest balance between the 5th and the end of the month, and credited once a year.
