Frequently Asked Questions

What is a CD (Certificate of Deposit)?

A CD is a savings account that holds a fixed amount of money for a fixed term (months to years) and earns interest at a higher rate than regular savings. At maturity, you get your principal plus interest back. If you withdraw early, you pay a penalty (typically 3-6 months of interest).

What is a good CD rate right now?

In 2024-2025, competitive CD rates range from 4.5-5.5% APY for 6-12 month CDs. Rates vary by institution — online banks and credit unions typically offer significantly higher rates than traditional big banks. Always compare rates before committing.

What is the early withdrawal penalty for CDs?

Common penalties: 3 months interest (CDs under 1 year), 6 months interest (1-2 year CDs), 12 months interest (2-5 year CDs). Some banks have more severe penalties. Calculate the penalty before breaking a CD early — it can eat into your principal.

What is a CD ladder strategy?

Instead of locking all money in one CD, split it into multiple CDs with staggered maturities. Example: $20,000 split into four $5,000 CDs maturing in 6, 12, 18, and 24 months. As each matures, reinvest at the current rate. You get liquidity every 6 months.

CD vs high-yield savings account: which is better?

HYSAs offer flexibility — no maturity date, can add/withdraw money, competitive rates. CDs offer higher rates in exchange for locking money away. If rates are rising, prefer HYSAs (you can move money as rates improve). If rates are falling, lock in CDs at the current higher rate.

CD Ladder Example

$20,000 split into 4 CDs at 5% APY:

CDAmountMatures
CD #1$5,0006 months
CD #2$5,00012 months
CD #3$5,00018 months
CD #4$5,00024 months

Access $5,000 every 6 months. Reinvest at current rates.
