1. What is Compound Interest?

Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods. It allows your investment to grow at an accelerating rate over time, making it a powerful tool for wealth creation.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ A = P \times (1 + r/n)^{n \times t} \]

Where:

\( A \) — Future value of the investment
\( P \) — Principal amount (initial investment)
\( r \) — Annual interest rate (in decimal form)
\( n \) — Number of compounding periods per year
\( t \) — Time the money is invested for (in years)

Explanation: The formula calculates how much your investment will grow when interest is compounded at regular intervals.

3. Importance of Compound Interest in India

Details: Compound interest is fundamental to various Indian financial products including fixed deposits, recurring deposits, mutual funds, and provident funds. Understanding compound interest helps investors make informed decisions about their savings and investments.

4. Using the Calculator

Tips: Enter the principal amount in rupees, annual interest rate as a percentage, number of compounding periods per year (e.g., 12 for monthly, 4 for quarterly, 1 for annually), and time period in years. All values must be positive numbers.
