Worth knowing

APY vs quoted rate

The quoted rate is nominal. APY includes compounding, so it runs slightly higher, and it is the figure banks must disclose. When two offers compound differently, compare their APYs.

Daily vs monthly compounding

More frequent compounding helps less than people expect. On $10,000 at 4.50% for one year, daily compounding beats annual by about ten dollars.

What happens at maturity

The bank returns your deposit plus the interest. Most CDs renew automatically unless you act during a short grace period, and the details are in your bank's disclosure.
