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 investments to grow exponentially over time, making it a powerful concept in finance and investing.

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 (AUD)
\( P \) — Principal amount (AUD)
\( r \) — Annual interest rate (decimal)
\( n \) — Number of compounding periods per year
\( t \) — Time in years

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

3. Importance of Compound Interest

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

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between simple and compound interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on both principal and accumulated interest.

Q2: How does compounding frequency affect returns?
A: More frequent compounding (e.g., monthly vs annually) results in higher returns due to interest being calculated more often.

Q3: Is this calculator specific to Australian interest rates?
A: While designed with Australian users in mind, the calculator works with any currency. The formula is universal for compound interest calculations.

Q4: Can I use this for investment planning?
A: Yes, this calculator helps estimate future investment values, but remember that actual returns may vary due to market fluctuations.

Q5: What are typical compounding periods in Australia?
A: Common compounding periods in Australian financial products include monthly, quarterly, and annually, depending on the investment type.
