1. What is the Compound Interest Formula?

The compound interest formula calculates the future value of an investment or savings account where interest is earned on both the initial principal and the accumulated interest from previous periods. It's a powerful concept for long-term wealth building.

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 shows how your money grows exponentially over time as interest is earned on both your initial deposit and the accumulated interest.

3. Importance of Compound Interest

Details: Compound interest is often called the "eighth wonder of the world" for its ability to significantly grow wealth over time. Understanding compound interest is crucial for financial planning and retirement savings.

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 does compounding frequency affect returns?
A: More frequent compounding (daily vs. annually) results in higher returns due to interest being calculated more often.

Q3: What's a typical interest rate for high-yield savings?
A: Rates vary but typically range from 0.5% to 5% APY, depending on economic conditions and the financial institution.

Q4: Are high-yield savings accounts safe?
A: Yes, they are typically FDIC insured up to $250,000 per depositor, per institution.

Q5: How often do high-yield accounts compound interest?
A: Most compound interest daily and credit it to your account monthly, but this can vary by institution.
