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 savings to grow at a faster rate compared to simple interest, especially with high interest rates and frequent compounding.

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

Explanation: The formula calculates how much your initial investment will grow over time with compound interest, taking into account the frequency of compounding.

3. Importance of High Interest Rates

Details: High interest rates significantly accelerate wealth accumulation through compound interest. Even small differences in interest rates can lead to substantial differences in final amounts over long periods.

4. Using the Calculator

Tips: Enter 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.

Q2: How often do banks typically compound interest?
A: Common compounding frequencies include daily, monthly, quarterly, and annually. More frequent compounding results in higher returns.

Q3: Are high interest rates always better?
A: While high interest rates benefit savers, they can be disadvantageous for borrowers. Always consider the context and your financial position.

Q4: What is the rule of 72?
A: The rule of 72 estimates how long it takes for an investment to double: 72 divided by the interest rate gives the approximate number of years.

Q5: Are there risks with high-interest accounts?
A: Some high-interest accounts may have restrictions or requirements. Always read the terms carefully and ensure the institution is FDIC insured.
