CD rates are set by individual banks and credit unions, influenced heavily by the federal funds rate, and they lock in a fixed return for a specific period of time. When you open a certificate of deposit, you agree to leave your money untouched for a set term, and in exchange, the bank pays you a guaranteed interest rate that’s typically higher than a regular savings account. Understanding how these rates are determined, how your interest compounds, and what happens if you need your money early will help you get the most from a CD.
What Determines the Rate You’re Offered
Three main forces shape the CD rates you see advertised: the federal funds rate, the bank’s own business strategy, and the term length you choose.
The federal funds rate is the benchmark interest rate set by the Federal Reserve. When it goes up, CD rates tend to follow. When it drops, CD rates fall too. The Fed lowered its benchmark rate three times in 2025, and CD rates declined in response. As of early 2026, the rate sits at 3.5% to 3.75% after officials held it steady.
Banks also set rates based on their own need for deposits. A bank balances what it pays you against what it earns from lending your money out. If a bank charges borrowers 9% on loans, it can offer you 4% or more on a CD and still turn a profit on the spread. Banks that are aggressively trying to attract new deposits, particularly online banks with lower overhead costs, will offer higher rates than competitors that already have plenty of cash on hand.
The FDIC tracks national average deposit rates across all institutions, and those averages sit well below what the best-paying banks offer. National averages for CDs currently hover between about 1.35% and 1.53% depending on the term, while the highest-paying CDs from competitive banks range from roughly 4.10% to 4.78%. That gap is significant: on a $10,000 deposit, the difference between 1.5% and 4.5% is about $300 per year. Shopping around is one of the simplest ways to earn more.
How Term Length Affects Your Rate
CD terms typically range from three months to five years, and the relationship between term length and rate isn’t always what you’d expect. In a straightforward environment, longer terms pay higher rates because you’re locking up your money for more time. But the current rate environment can flip that pattern.
If banks expect the Fed to cut rates in the near future, they may offer higher yields on short-term CDs to attract depositors now, knowing that when those CDs mature, customers will have to renew at a lower rate. Conversely, if rates are expected to rise, a bank might pay more on longer-term CDs to lock depositors in before rates climb further. This is why you’ll sometimes see a six-month CD paying more than a three-year CD.
APY, Compounding, and What You Actually Earn
CD rates are expressed as an APY, or annual percentage yield. APY reflects both the stated interest rate and the effect of compounding, which is when the interest you’ve already earned starts earning interest of its own. This makes APY the most accurate number for comparing what you’ll actually earn across different CDs.
Compounding frequency matters. A CD that compounds daily will earn slightly more than one that compounds monthly or quarterly, even if they advertise the same base interest rate. The APY accounts for this difference, so when two CDs list the same APY, you’ll earn the same amount regardless of how often they compound. Always compare APY to APY, not raw interest rates.
Here’s a simple example: if you put $10,000 into a CD with a 4.50% APY for one year, you’d earn $450 in interest. On a five-year CD at 4.00% APY, that same $10,000 would grow to roughly $12,167 thanks to compounding, earning you about $2,167 over the full term.
Fixed-Rate, Bump-Up, and Step-Up CDs
Most CDs are fixed-rate, meaning the rate you lock in on day one stays the same for the entire term. This is the core appeal of a CD: you know exactly what you’ll earn no matter what happens to interest rates in the broader market.
Bump-up CDs give you the option to request a rate increase during your term if rates rise. You decide when to use this option, but most bump-up CDs only allow one increase. The trade-off is that the starting rate on a bump-up CD is usually lower than what you’d get on a comparable fixed-rate CD.
Step-up CDs take a different approach. The bank schedules automatic rate increases at set intervals throughout the term. You don’t choose when the rate goes up; the bank determines the schedule and the amounts in advance when you open the CD. Like bump-up CDs, the initial rate is often lower than a standard fixed-rate option.
Both specialty types can make sense if you believe rates will rise significantly during your CD’s term, but in most cases a standard fixed-rate CD at a competitive institution will deliver a better overall return.
Early Withdrawal Penalties
If you pull your money out of a CD before the term ends, you’ll pay an early withdrawal penalty. This penalty is almost always calculated as a certain number of days’ worth of interest, typically ranging from 60 to 365 days depending on the CD’s term length. Longer-term CDs carry steeper penalties.
To see what a penalty looks like in dollars: take a $10,000 CD earning 4% APY with a 90-day interest penalty. Divide the annual interest ($400) by 365 to get your daily interest (about $1.10), then multiply by 90 penalty days. You’d forfeit roughly $98.63. If you haven’t earned that much in interest yet, say you withdraw just a few weeks after opening the CD, the penalty can eat into your original deposit. You’d get back less than you put in.
Some banks offer no-penalty CDs that let you withdraw early without a fee, but these typically pay lower rates than standard CDs. Whether the flexibility is worth the lower return depends on how certain you are that you won’t need the money before the term ends.
How CD Laddering Works
A CD ladder is a strategy where you split your money across multiple CDs with staggered maturity dates. For example, instead of putting $10,000 into a single three-year CD, you might open five CDs of $2,000 each with terms of one, two, three, four, and five years. As each CD matures, you can either use the cash or reinvest it into a new five-year CD at the current rate.
This approach gives you regular access to a portion of your money (reducing the chance you’ll need to pay early withdrawal penalties) while still capturing the higher rates that longer terms often provide. In a rising-rate environment, each maturing CD gets reinvested at the new, higher rate. In a falling-rate environment, you still have longer-term CDs locked in at the older, higher rates.
What Happens When Your CD Matures
When your CD reaches the end of its term, most banks give you a grace period, usually seven to ten days, to decide what to do. You can withdraw the money, move it to a different account, or renew the CD. If you do nothing, the bank will typically auto-renew the CD into a new term of the same length at whatever rate it’s currently offering, which could be higher or lower than what you originally locked in.
It’s worth setting a reminder a few days before your CD matures. The auto-renewal rate is often not the bank’s most competitive offering, and you may find a better deal by shopping around or negotiating directly.
