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 an accelerating rate over time, making it a powerful tool for wealth accumulation in high-yield savings accounts.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ A = P \times (1 + R / n)^{n \times T} \]

Where:

$ A $ — Maturity amount ($)
$ P $ — Principal amount ($)
$ R $ — Annual interest rate (decimal)
$ n $ — Compounding frequency per year
$ T $ — Time period (years)

Explanation: The formula calculates how much your initial investment will grow based on the interest rate and compounding frequency over a specific time period.

3. Importance of Compound Interest

Details: Compound interest is fundamental to long-term savings growth. The more frequently interest compounds, the faster your money grows. High-yield savings accounts typically offer better rates than traditional savings accounts, maximizing the compounding effect.

4. Using the Calculator

Tips: Enter the principal amount in dollars, annual interest rate as a percentage, select compounding frequency, and time period 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 does compounding frequency affect returns?
A: More frequent compounding (daily vs. annually) results in higher returns because interest is calculated and added to the principal more often.

Q3: Are high-yield savings accounts FDIC insured?
A: Yes, most high-yield savings accounts at FDIC-member banks are insured up to $250,000 per depositor.

Q4: What's a typical APY for high-yield savings accounts?
A: Rates vary but typically range from 3-5% APY, though this fluctuates with market conditions.

Q5: Can I withdraw money from a high-yield savings account?
A: Yes, though some accounts may have withdrawal limits or minimum balance requirements to earn the highest rates.
