PPF Compounding Formulas
Interest in PPF is calculated on the minimum balance between the 5th and the end of the month, but it is compounded annually at the end of each year. The maturity amount for annual contributions is given as:
Where:
- F = Maturity value of PPF
- P = Annual contribution amount
- r = Annual interest rate
- n = Total number of years (usually 15)
Note: This formula assumes that the contribution is made as a lump sum at the beginning of the financial year (before April 5th), which maximizes interest earnings.
