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 savings to grow at an accelerating rate over time, making it a powerful tool for long-term wealth accumulation in Australia.

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

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

3. Importance of Compound Interest Calculation

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

4. Using the Calculator

Tips: Enter the principal amount in AUD, annual interest rate as a decimal (e.g., 0.05 for 5%), number of compounding periods per year, and time period in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)
