1. What is a PPF After 15 Years Calculator?

Definition: This calculator estimates the maturity amount of a Public Provident Fund (PPF) account after the initial 15-year period plus any extension periods.

Purpose: It helps investors plan their long-term savings by projecting how their PPF investment will grow during extension periods.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Maturity \) — Final maturity amount after extension ($)
• \( Initial\ Maturity \) — Maturity amount at the end of 15 years ($)
• \( i \) — Annual interest rate (in decimal, e.g., 0.071 for 7.1%)
• \( extension \) — Number of years extending beyond 15 years

Explanation: The formula calculates compound interest on the initial maturity amount for the extension period.

3. Importance of PPF Maturity Calculation

Details: Understanding potential returns helps in financial planning, retirement preparation, and comparing PPF with other investment options.

4. Using the Calculator

Tips: Enter the initial maturity amount (after 15 years), current interest rate (default 0.071 for 7.1%), and extension period in years (default 5). All values must be ≥ 0.
