Frequently Asked Questions

Are CD rates fixed for the entire term?

Yes, traditional CDs lock in a fixed rate for the term, unlike savings accounts where rates can change, this predictability is one of the main appeals of CDs.

Are CDs a good investment?

CDs offer safety and predictable returns, making them useful for short-term goals or a portion of a conservative portfolio, though they typically offer lower returns than stock market investments over the long run.

What's the difference between APY and interest rate on a CD?

APY (Annual Percentage Yield) accounts for compounding within the year, giving a more accurate picture of actual annual return than the stated nominal rate alone.
