PPF Calculator

About PPF Calculator

The Public Provident Fund (PPF) is a popular long-term investment scheme in India with tax benefits. Our PPF calculator helps you estimate:

• Total investment over selected period
• Interest earned through compounding
• Final maturity amount

How PPF Calculation Works:

PPF calculations use compound interest formula with annual compounding:

Maturity Amount = P × [( (1 + r)^n - 1 ) / r ]

Where:
P = Annual investment
r = Interest rate (decimal)
n = Number of years

Example Calculation:

If you invest ₹12,000 yearly for 15 years at 7.1% interest:

• Total Investment: ₹1,80,000
• Interest Earned: ₹1,51,548
• Maturity Value: ₹3,31,548

Key Features:

• 15-year lock-in period (extendable)
