Instead of one CD, split the deposit into five equal rungs maturing 1 through 5 years out. One rung frees up every year while the rest keep earning the longer rate.

Certificates of deposit, explained
How Certificate of Deposit Interest Works
A certificate of deposit (CD) pays a fixed interest rate in exchange for keeping your money deposited for a set period, known as the term. Most CDs compound interest daily or monthly and credit it to your account, allowing your earnings to generate additional interest over time. Withdrawing funds before the maturity date typically triggers an early withdrawal penalty, which can range from a few months' to a full year's worth of interest depending on the institution and term length.
CD Terms and Current Rates Compared
CD terms typically range from 3 months to 5 years, with longer terms generally offering higher annual percentage yields (APY) to compensate for locking up your money. As of 2025, competitive online banks offer rates significantly higher than the national average, especially for 12-month and 18-month terms. Short-term CDs (3 to 6 months) provide more flexibility but usually at lower rates, while 5-year CDs lock in today's rate but carry the risk that rates may rise during the term.
CD Ladder Strategy Explained
A CD ladder involves dividing your savings across multiple CDs with staggered maturity dates, for example, one each at 1, 2, 3, 4, and 5 years. As each CD matures, you reinvest it into a new long-term CD at the current rate, ensuring you always have funds becoming available while capturing higher long-term yields. This strategy balances liquidity with earning potential and reduces the risk of locking all your money into a single rate. CD ladders are especially effective during periods of rising or uncertain interest rates.
CDs vs High-Yield Savings Accounts
Both CDs and high-yield savings accounts are FDIC-insured up to $250,000, but they serve different purposes. CDs offer a guaranteed fixed rate for the entire term, protecting you if rates drop, but penalize early withdrawals. High-yield savings accounts provide full liquidity with no withdrawal penalties, though their rates can fluctuate as the Federal Reserve adjusts monetary policy. If you won't need the money for a specific period and want rate certainty, a CD is usually the better choice; for emergency funds or flexible savings, a high-yield savings account is more practical.
Common questions
How much interest does a CD earn?
At 4.75% APY, a $10,000 CD earns about $487 in the first year and about $997 over 2 years with monthly compounding. CD rates are guaranteed for the full term, unlike savings accounts where rates can change.
What is the penalty for early CD withdrawal?
Early withdrawal penalties vary by bank and term. Typical penalties: 3 months of interest for terms under 1 year, 6 months for 1-year CDs, and 12 months for longer terms. Some online banks offer no-penalty CDs with slightly lower rates.
What is a CD ladder and why should I consider one?
A CD ladder splits your deposit across multiple CDs with staggered maturity dates (e.g., 1-year, 2-year, 3-year). As each CD matures, you reinvest at the longest term. This balances higher long-term rates with regular access to some of your money.
Are CDs a good investment right now?
With rates at 4%-5% APY in 2024, CDs are attractive for risk-averse savers. They are FDIC-insured up to $250,000 and guarantee your rate. CDs are best for money you will not need during the term, such as emergency fund reserves or short-term savings goals.
Are CDs better than high-yield savings accounts?
CDs typically offer slightly higher rates (0.25%-0.50% more) in exchange for locking up your money. Savings accounts offer flexibility to withdraw anytime. If you can commit to a term, CDs guarantee the rate even if market rates drop. If you need liquidity, a high-yield savings account is better.
Estimates for planning only. Real returns depend on the exact rate, compounding method, and terms your bank offers, plus any early withdrawal penalty. CD deposits at insured banks are protected by the FDIC up to $250,000 per depositor, per bank, per ownership category. Verify the rate and terms before you open the account.
