1. What is the PPF Calculation Formula?

The PPF (Public Provident Fund) calculation formula estimates the maturity amount of an investment including an existing balance. It accounts for both the initial amount and regular contributions over time with compound interest.

2. How Does the Calculator Work?

The calculator uses the PPF formula:

Where:

• \( M \) — Maturity amount
• \( Existing \) — Initial/existing balance
• \( \sum P \) — Total contributions over the period
• \( r \) — Annual interest rate (as decimal)
• \( n \) — Number of years

Explanation: The formula calculates the future value of both the existing balance and all contributions, compounded annually at the given interest rate.

3. Importance of PPF Calculation

Details: Accurate PPF calculation helps in financial planning, retirement savings estimation, and understanding the growth potential of long-term investments with compound interest.

4. Using the Calculator

Tips: Enter existing balance, annual contributions, annual interest rate (as percentage), and number of years. All values must be valid (non-negative amounts, positive years).
