FAQ — answers Google & AI can cite

What is APY?

Annual Percentage Yield — the yearly return including compounding. A 4.50% APY turns $10,000 into about $10,450 in one year.

APY vs interest rate — what is the difference?

The interest rate ignores compounding frequency; APY includes it, so APY is the number to compare between accounts.

How is CD interest calculated?

Maturity value = principal × (1 + APY)^years. Early withdrawal usually costs some interest as a penalty.

Are CDs safe?

Bank CDs are FDIC-insured up to $250,000 per depositor — among the safest places for cash you will not need soon.

Is this financial advice?

No — an informational estimate. Rates change; confirm with your bank.
