1. What is Compound Interest?

Compound interest is interest calculated on the initial principal and also on the accumulated interest of previous periods. In high-yield savings accounts, your money grows faster because you earn interest on both your original deposit and the interest that accumulates over time.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ Interest = P \times (1 + r/n)^{n \times t} - P \]

Where:

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

Explanation: The formula accounts for how often interest is compounded (daily, monthly, quarterly, etc.) and how that frequency affects your total returns.

3. Importance of High-Yield Savings

Details: High-yield savings accounts typically offer much higher interest rates than traditional savings accounts, helping your money grow faster while remaining FDIC-insured and liquid.

4. Using the Calculator

Tips: Enter your principal amount, annual interest rate (as a decimal, e.g., 0.05 for 5%), number of compounding periods per year (12 for monthly), and time in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How often do high-yield accounts compound interest?
A: Most compound interest daily, though the frequency can vary by institution. Daily compounding yields slightly better returns than monthly.

Q2: What's a good interest rate for a high-yield account?
A: As of 2023, rates between 3-5% APY are competitive, though rates fluctuate with the federal funds rate.

Q3: Are there limits on withdrawals?
A: Federal Regulation D limits certain types of withdrawals to 6 per month, though this was suspended during COVID.

Q4: How is this different from a CD?
A: CDs typically offer higher rates but require you to lock up your money for a set term, while high-yield savings accounts offer more liquidity.

Q5: Is my money safe in a high-yield account?
A: Yes, as long as the bank is FDIC-insured (up to $250,000 per depositor, per account type).
