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 faster over time as interest is earned on both the original amount and the interest that has been added to it.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

\( FV \) — 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 an investment will grow over time with compound interest, taking into account how frequently the interest is compounded.

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 money can grow exponentially over time.

4. Using the Calculator

Tips: Enter the principal amount in AUD, annual interest rate as a percentage, number of compounding periods per year, and time in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q3: Does compounding frequency affect the final amount?

Q4: Are there taxes on interest earned?
A: Yes, interest earned on savings accounts is generally considered taxable income in Australia and must be declared to the ATO.

Q5: What's a good interest rate for Australian savings accounts?
