1. What is Compound Interest?

Compound interest is 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 particularly powerful for long-term savings.

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 frequently interest is compounded, with more frequent compounding resulting in higher returns.

3. Importance of High-Yield Savings

Details: High-yield savings accounts typically offer interest rates much higher than traditional savings accounts, making them an excellent place to keep emergency funds or short-term savings while maintaining liquidity.

4. Using the Calculator

Tips: Enter the principal amount, annual interest rate (as a percentage), select how often interest is compounded, and the time period. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How often do high-yield savings accounts compound interest?
A: Most compound interest daily, but pay it out monthly. Check with your specific financial institution for their compounding schedule.

Q2: Are high-yield savings accounts safe?
A: Yes, when offered by FDIC-insured banks (up to $250,000 per depositor), they carry virtually no risk to your principal.

Q3: What's a good interest rate for a high-yield savings account?
A: Rates vary, but typically 4-5% APY is considered good as of 2023-2024, much higher than traditional savings accounts.

Q4: How does compounding frequency affect returns?
A: More frequent compounding (daily vs. monthly) results in slightly higher returns due to the "interest on interest" effect.

Q5: Are there limits on withdrawals?
A: Federal Regulation D limits certain types of withdrawals to 6 per month, though this was suspended during COVID and may vary by bank.
