1. What is Compound Interest?

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. It's a powerful concept in finance that allows investments to grow exponentially over time.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

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

Explanation: The formula accounts for periodic compounding, where interest is added to the principal at regular intervals, resulting in exponential growth.

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for financial planning, retirement savings, and investment decisions. It demonstrates how money can grow over time and why starting early is beneficial.

4. Using the Calculator

Tips: Enter principal in CAD, annual interest rate as a percentage (e.g., 5 for 5%), number of compounding periods per year, and investment duration in years. All values must be positive.

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 include annually, semi-annually, quarterly, monthly, or daily, depending on the financial product.

Q3: Does this calculator account for taxes?
A: No, this calculates gross returns. Remember that investment earnings may be taxable in Canada (TFSA/RRSP exceptions apply).

Q4: What's the Rule of 72?
A: A quick way to estimate doubling time: divide 72 by the interest rate. At 6% interest, money doubles in about 12 years.

Q5: How accurate is this calculator?
A: It provides precise mathematical calculations but doesn't account for changing rates, additional contributions, or fees.
