How to Choose the Best CD
When comparing CDs, consider these factors:
- APY (Annual Percentage Yield): The actual rate of return, accounting for compounding.
- Term Length: Shorter terms offer less interest but more flexibility.
- Minimum Deposit: Some banks require higher minimums for their best rates.
- Early Withdrawal Penalty: Typically 3-12 months of interest.
- FDIC Insurance: Ensure your bank is FDIC-insured up to $250,000.
Certificate of Deposit (CD) Information
What is a CD?
A Certificate of Deposit (CD) is a savings account that holds a fixed amount of money for a fixed period of time (the term) and pays a fixed interest rate. CDs generally offer higher interest rates than regular savings accounts because you agree to leave your money untouched for the term.
How Do CDs Work?
When you open a CD, you deposit a lump sum for a set term (from 3 months to 5 years). The bank pays you interest at regular intervals. At the end of the term (maturity date), you get back your initial deposit plus the accrued interest. Withdrawing money before maturity typically results in a penalty.
Types of CDs
- Traditional CD: Fixed rate for a fixed term
- High-Yield CD: Offers higher interest rates than standard CDs
- Bump-Up CD: Allows you to increase your rate if rates rise
- Liquid CD: Allows penalty-free withdrawals (typically with lower rates)
- Jumbo CD: Requires a large minimum deposit (usually $100,000+)
Benefits of CDs
- Higher interest rates than regular savings accounts
- Fixed, predictable returns
- Low risk (FDIC insured up to $250,000)
- Helps prevent impulsive spending (due to withdrawal penalties)
CD Ladder Strategy
A CD ladder is a strategy where you divide your investment across multiple CDs with different maturity dates. For example, instead of investing $10,000 in a single 5-year CD, you could invest $2,000 in 1-year, 2-year, 3-year, 4-year, and 5-year CDs. As each CD matures, you reinvest it in a new 5-year CD. This strategy provides regular access to funds while taking advantage of higher long-term rates.

✅ FDIC Protection – Insured up to $250,000 per depositor
✅ Discipline Mechanism – Penalties discourage impulsive withdrawals

Common CD Mistakes to Avoid
❌ Ignoring Early Withdrawal Penalties – Typically 3-12 months of interest
❌ Overlooking Callable CDs – Banks may terminate high-rate CDs early
❌ Forgetting Maturity Dates – Funds often auto-renew at lower rates if not claimed
❌ Neglecting FDIC Limits – Spread large balances across institutions
