1. What is Compound Interest?

Compound interest is interest calculated on the initial principal and also on the accumulated interest of previous periods. It allows savings to grow at an accelerated rate compared to simple interest, making it a powerful tool for long-term wealth building in Australian savings accounts.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

\( A \) — Maturity amount (AUD)
\( P \) — Principal amount (AUD)
\( R \) — Annual interest rate (as decimal)
\( n \) — Compounding frequency per year
\( T \) — Time period in years

Explanation: The formula calculates how much your savings will grow when interest is compounded at regular intervals, accounting for both your initial deposit and accumulated interest.

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for effective financial planning. It demonstrates how regular savings can grow significantly over time, helping Australians make informed decisions about their savings and investment strategies.

4. Using the Calculator

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