1. What is the Compound Interest Formula?

The compound interest formula calculates the future value of an investment or savings account where interest is earned on both the initial principal and the accumulated interest from previous periods. This is the standard method used by Indian banks for savings account interest calculation.

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 (decimal)
\( n \) — Number of times interest is compounded per year
\( t \) — Time the money is invested for (years)

Explanation: The formula accounts for the effect of compounding, where interest is added to the principal at regular intervals, allowing your money to grow faster over time.

3. Importance of Compound Interest Calculation

Details: Understanding compound interest is crucial for financial planning, savings growth estimation, and making informed investment decisions. It demonstrates how small, regular savings can grow significantly over time.

4. Using the Calculator

Tips: Enter the principal amount in rupees, annual interest rate as a percentage, select compounding frequency, and time period in years. All values must be positive numbers.
