자주 묻는 질문
What is a Certificate of Deposit (CD) and how does it work?+
A Certificate of Deposit is a savings product offered by banks and credit unions where you deposit money for a fixed period (the term) at a guaranteed interest rate. In exchange for locking up your money, you typically earn a higher interest rate than a regular savings account. When the CD matures (reaches the end of its term), you receive your original deposit plus all accrued interest. Terms range from as short as 1 month to as long as 10 years.
What is the difference between APY and APR for CDs?+
APY (Annual Percentage Yield) reflects the total amount of interest you earn in a year including the effect of compounding. APR (Annual Percentage Rate) is the simple interest rate without compounding factored in. Because CDs compound interest, the APY is always slightly higher than the APR. Banks are required to advertise APY, making it easier to compare offers. For example, a 5.00% APR compounded daily yields an APY of approximately 5.13%.
What is a CD ladder strategy and why should I use one?+
A CD ladder involves splitting your total investment across multiple CDs with staggered maturity dates (e.g., 1-year, 2-year, 3-year, 4-year, and 5-year CDs). As each shorter-term CD matures, you can reinvest it at the longest term to capture higher rates, or access the cash if needed. This strategy balances liquidity with higher long-term rates, reducing the risk of locking all your money away at a single rate while still earning more than a savings account.
What are typical early withdrawal penalties for CDs?+
Early withdrawal penalties vary by bank and CD term. Common penalties include 3 months of interest for CDs with terms under 1 year, 6 months of interest for 1-year CDs, and 12 months or more of interest for longer-term CDs. Some banks charge a flat fee instead. In extreme cases, the penalty can eat into your principal if you withdraw very early. Always check your bank's specific penalty terms before opening a CD.
How does compounding frequency affect my CD earnings?+
Compounding frequency determines how often earned interest is added to your balance to earn additional interest. Daily compounding yields the most because interest is calculated and added every day. Monthly, quarterly, and annual compounding produce progressively less total interest. However, the differences are relatively small. For example, on a $10,000 CD at 5% APY for 1 year, the difference between daily and annual compounding is typically only a few dollars.
Are CDs safe? Is my money insured?+
CDs from FDIC-insured banks are insured up to $250,000 per depositor, per bank, per ownership category. Credit union CDs (called share certificates) are similarly insured by the NCUA. This makes CDs one of the safest investment options available. The trade-off is that CD rates are generally lower than potential stock market returns, but your principal is guaranteed and the interest rate is locked in for the term.
When is the best time to open a CD?+
The best time to open a CD is when interest rates are high relative to historical norms, or when you expect rates to decline. Locking in a high rate before the Federal Reserve cuts rates means you benefit from that rate for the entire CD term. If rates are expected to rise, shorter-term CDs or a CD ladder strategy lets you reinvest at higher rates as they become available.
