🌱 PPF Calculator: Plan Your Long-Term Savings with Ease
A PPF Calculator helps you estimate how much wealth you can accumulate by investing in a Public Provident Fund — one of India’s safest and most tax-friendly long-term savings schemes. Just enter your yearly contribution and let the calculator show your maturity value and total interest earned.
🧮 How is PPF Interest Calculated?
PPF returns are compounded annually and calculated using this formula:
A = P × (1 + r/n)^(n × t)
Where:
A = Maturity amount
P = Annual investment
r = Interest rate (currently 7.1% p.a.)
n = Compounding frequency (annually for PPF)
t = Tenure (in years — minimum 15 years)
Note: Interest is calculated monthly but compounded annually. Contributions before the 5th of each month earn more interest.

Using the calculator is simple:
Enter your annual investment amount (between ₹500 and ₹1.5 lakh).
Choose the investment duration (minimum 15 years, can extend up to 50).

This helps you visualize long-term savings and retirement goals.
