❓ Frequently Asked Questions

What is a Certificate of Deposit (CD)?

A CD is a savings account that holds a fixed amount for a fixed period at a fixed rate. Terms range from 3 months to 5 years. Banks offer higher rates than regular savings in exchange for locking your money. CDs are FDIC insured up to $250,000 per depositor per bank.

Are CD rates fixed or variable?

Traditional CDs have fixed rates throughout the term. This protects you if rates drop but you miss out if rates rise. Variable-rate CDs allow rate changes. For most savers, fixed-rate CDs offer the best predictability.

What happens if I withdraw from a CD early?

Early withdrawal triggers a penalty of 3-12 months' interest depending on the term. For CDs under 12 months, it's usually 3 months' interest. For 12-24 months, often 6 months. The penalty can eat into your principal if you haven't earned enough interest.

Should I build a CD ladder?

A CD ladder spreads savings across staggered maturity dates (e.g., $4,000 each in 1-5 year CDs). As each matures, reinvest in a new 5-year CD. This gives regular access to funds while capturing higher long-term rates.

How are CD earnings taxed?

CD interest is taxed as ordinary income in the year earned, even if you don't withdraw. A $10,000 CD at 5% APY generates about $500/year in taxable income. Use a CD IRA to defer taxes until withdrawal.

What is APY vs APR on CDs?

APY includes compound interest; APR is the simple annual rate. A 4.90% APR compounded monthly equals 5.01% APY. Always compare CDs using APY — it reflects what you'll actually earn.

Are CDs better than high-yield savings accounts?

HYSA offers flexibility with variable rates. CDs lock in rates for the term. If you expect rates to fall, CDs are better. If you may need the money, HYSA is safer. Currently both offer similar rates (4-5%+).

How much money should I put in a CD?

Only put money you won't need during the term. Keep 3-6 months expenses in savings for emergencies, then use CDs for excess savings. CDs are FDIC insured up to $250,000 per depositor per bank.
