About the PPF Calculator
Our free Public Provident Fund (PPF) Calculator helps Indian citizens project the long-term wealth accumulation, guaranteed interest earnings, and maturity values of their PPF accounts over the mandated 15-year lock-in period and beyond.
How PPF Interest and Maturity Are Calculated
Public Provident Fund interest is calculated on the lowest balance between the close of the 5th day and the end of the month, but it is compounded and credited annually at the end of the financial year. The compound growth formula governing PPF accumulation is:
$$A = P \times \left( \frac{(1 + r)^n - 1}{r} \right)$$
Where:
- A: Maturity value of the account
- P: Annual principal deposit amount
- r: Annual interest rate expressed as a decimal
- n: Total tenure in years (minimum 15 years)
