What is a CD ladder and how do I build one?
A CD ladder spreads investments across multiple CDs with different maturity dates. Example: Split $10,000 into 5 CDs: 1-year, 2-year, 3-year, 4-year, 5-year. As each matures, reinvest at the longest term. This provides annual access to funds and higher average rates.
What's the difference between CD interest rate and APY?
Interest rate is the base rate paid on your deposit. APY (Annual Percentage Yield) includes compounding effects. Example: 5.00% interest rate compounded monthly = 5.12% APY. APY is the true annual return and should be used to compare CDs.
