The PPF calculator helps you estimate the maturity amount and interest earned on your Public Provident Fund investment. Enter your yearly investment, interest rate, and tenure to see your results instantly.
PPF maturity is calculated using the formula for recurring annual investments compounded yearly:
M = P × [ ( (1 + r)^n - 1 ) / r ]
Where:
M = Maturity amount
P = Yearly investment
n = Number of years
r = Interest rate per annum (in decimal)
Example: If you invest ₹1,50,000 per year for 15 years at 7.1% p.a., your maturity amount will be calculated accordingly.
