1. What Is The Compound Interest Formula?

The compound interest formula calculates the future value of savings by accounting for interest earned on both the initial principal and accumulated interest over time. It's essential for understanding how savings grow in Australian financial institutions.

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 investment/loan (AUD)
\( P \) — Principal investment amount (AUD)
\( r \) — Annual interest rate (decimal)
\( n \) — Number of times interest is compounded per year
\( t \) — Time the money is invested/borrowed for (years)

Explanation: The formula demonstrates how money grows over time through compound interest, which is interest calculated on both the initial principal and accumulated interest from previous periods.

3. Importance Of Savings Interest Calculation

Details: Understanding compound interest is crucial for financial planning, retirement savings, and making informed investment decisions. It helps Australians maximize their savings growth and compare different investment options.

4. Using The Calculator

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