5. Frequently Asked Questions (FAQ)

Q1: What is a high-yield savings account?
A: A high-yield savings account typically offers higher interest rates than traditional savings accounts, helping your money grow faster through compound interest.

Q2: How does compounding frequency affect savings?
A: More frequent compounding (e.g., daily vs. annually) results in higher returns because interest is calculated and added to the principal more often.

Q3: What's the difference between APR and APY?
A: APR (Annual Percentage Rate) doesn't account for compounding, while APY (Annual Percentage Yield) does. This calculator uses the compounding method.

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

Q5: How often do high-yield accounts compound interest?
A: Most high-yield savings accounts compound interest daily and credit it monthly, but check with your specific financial institution for details.
