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's a powerful concept in finance that allows savings to grow at an accelerating rate over time, especially with high-interest savings accounts.

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
$ P $ — Principal investment amount
$ r $ — Annual interest rate (in decimal form)
$ n $ — Number of times interest is compounded per year
$ t $ — Time the money is invested for (in years)

Explanation: The formula calculates how much your initial investment will grow when interest is compounded multiple times per year over a specific period.

3. Importance of Compound Interest

Details: Compound interest is a fundamental concept in personal finance and investing. It demonstrates how money can grow exponentially over time, making it crucial for retirement planning, savings goals, and understanding the true potential of high-interest savings accounts.

4. Using the Calculator

Tips: Enter the principal amount in dollars, 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 both the principal and accumulated interest, leading to faster growth.

Q2: How often is interest typically compounded in savings accounts?
A: Most savings accounts compound interest daily, monthly, or quarterly. High-interest accounts often compound more frequently.

Q3: Does compounding frequency really make a difference?
A: Yes, the more frequently interest is compounded, the faster your money grows due to the "interest on interest" effect.

Q4: What is APY and how does it relate to compound interest?
A: APY (Annual Percentage Yield) represents the actual rate of return taking compounding into account, making it a better comparison metric than the nominal interest rate.

Q5: Are high-interest savings accounts safe?
A: High-interest savings accounts at FDIC-insured banks are generally safe, protecting your principal up to $250,000 per account holder.
