1. What is the Compound Interest Formula?

The compound interest formula calculates the future value of an investment or savings account where interest is compounded periodically. It shows how money grows over time through the power of compounding.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

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

Explanation: The formula accounts for interest being added to the principal, so that interest is earned on interest in subsequent periods.

3. Importance of Compound Interest Calculation

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

4. Using the Calculator

Tips: Enter the principal amount in dollars, annual interest rate as a decimal (e.g., 0.05 for 5%), number of compounding periods per year, 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 the principal plus accumulated interest.

Q2: How often is interest typically compounded in Canada?
A: Common compounding frequencies in Canada include monthly, quarterly, semi-annually, and annually, depending on the financial institution and account type.

Q3: Are there tax implications for interest earnings?
A: Yes, in Canada, interest income is generally taxable and must be reported on your annual tax return.

Q4: What's the Rule of 72?
A: The Rule of 72 is a quick way to estimate how long it takes for an investment to double: divide 72 by the annual interest rate.

Q5: Can this calculator be used for different currencies?
A: Yes, the formula works for any currency, though the calculator displays results in dollars by default.
