Best CD Rates for August 2026: Up to 4.50% APY

What is a certificate of deposit (CD)?

A certificate of deposit (CD) is a fixed-term savings product that locks money up for a fixed period of time.¹ You select a term, typically 6, 12, 18, or 24 months, though some CDs may extend for several years. Once you’ve chosen your term, you deposit your funds and earn a fixed interest rate for the entire term. Because the money stays locked in, banks offer rates that are higher than traditional savings accounts, and sometimes comparable to high-yield savings accounts, depending on the term and institution. When the CD reaches maturity, you can withdraw your original deposit along with the interest earned, or renew it into a new term.

How do CD accounts work?

When you open a CD, you lock in three things: the term, the rate (quoted as APY or annual percentage yield), and the early withdrawal penalty. APY is an annualized figure that already accounts for compounding under the bank’s method. The methodology for how the banks will credit that interest is different, and this is important to pay attention to. Some CDs credit interest monthly to the CD balance (so it compounds), others let you pay the interest out to another account (which stops compounding). If you withdraw early, the bank deducts a penalty (usually a number of months’ interest) from the interest you’ve earned.²

Example: Balances for a $10,000 deposit using different APYs and term lengths, all with monthly compounding.

Compounding frequency and interest crediting affect CD returns

Not all CDs are structured the same. As mentioned above, even when two CDs advertise the same rate, the way interest is calculated and credited can slightly change what you earn. These differences don’t seem very big when looking at them over a single year, but they matter for larger deposits or multi-year terms. For example, let’s compare two common scenarios that you will find when looking at different options:

Same rate but different compounding = different APY

Even though most CDs quote their yield as an annual percentage yield (APY), that number is derived from a nominal rate, which is compounded over time. The more frequently interest compounds, the more total interest you earn, but the difference is subtle. A CD that compounds daily will end the year slightly ahead of one that compounds monthly, while annual compounding produces the smallest total.

Example assumes a $10,000, 12-month CD with a nominal 4.90% annual rate.
Differences are small over one year but compound over larger balances or longer terms.

This example highlights how banks can advertise nearly identical nominal rates but show slightly different APYs once compounding is factored in. So, the lesson learned here is that you ALWAYS compare the APY, not just the stated rate, when choosing between CD offers.

Compound vs. payout interest = different return 

Another factor that shapes your CD returns is how the bank credits your interest. Two CDs can quote the same APY, but if one compounds internally and the other pays interest out to another account each month, your end result changes. The difference isn’t huge over a single year, but it grows with larger deposits or longer terms.

For example, let’s say you deposit $10,000 into a 12-month CD with a 5.00% APY. If you allow the interest to stay in the CD, it compounds, bringing your total to $10,500 at maturity. But if you choose monthly payouts to a checking account, you’ll receive about $488.89 in interest payments over the year, slightly less, because those payments don’t earn interest once withdrawn.

Example assumes a $10,000, 12-month CD at 5.00% APY. When interest is paid out instead of compounded, you earn slightly less overall because each payment stops generating new interest.

For savers seeking the best possible growth, leaving interest in the CD produces the best return. But investors who prefer regular income, such as retirees or those using CDs for monthly cash flow, often favor payout structures.

In the majority of cases, CD interest is taxed as ordinary income, whether it’s paid monthly or at the end of the term. The key difference is timing: if someone chooses monthly payouts, they’ll owe taxes on that interest each year, while if they wait until maturity, all the interest is taxed in the year the CD ends. That being said, there are some caveats to how CDs are taxed that might not always fit this model.³

Are CDs safe?

Yes, CDs are some of the safest financial products out there. CDs at banks are insured by the FDIC up to $250,000 per depositor, per insured bank.⁴ This means that as long as your CD isn’t worth several million dollars and is stuck at only one bank, you are totally fine. Credit union “share certificates” carry equivalent coverage through the NCUA. The principal risk isn’t default, it’s liquidity that’s the risk: needing the money before maturity and paying a penalty.

Early withdrawal penalties (How much can it cost?)

Penalties vary by bank and term, but a common pattern is:

• Terms ≤ 12 months: roughly 3–6 months of interest forfeited.
• Terms > 12 months: roughly 6–12 months of interest (sometimes more) forfeited.

No one likes to pay a penalty, and they are usually taken from only the interest first. If you close very early, the penalty can eat most or all of the interest, but it typically does not reduce your original principal unless your accrued interest is insufficient to cover the penalty (rare if you’ve held the CD for a while). That being said, always check the fine print that was provided to you with your CD deposit by the bank or financial institution!

CD laddering: How to invest in multiple CDs for cash flow

You might have come across the term “CD Laddering” and might not have understood what it meant. CD laddering means splitting money into several CDs with different maturity dates instead of locking it all into one. It helps earn higher rates over time while keeping some funds accessible at regular intervals. A CD ladder staggers maturity dates so you aren’t “all-in” on one long term. It gives you periodic access to cash and the option to reinvest at new rates.

When the first CD in your ladder matures, you can either withdraw the cash or reinvest it in a longer-term CD to keep your ladder going. This lets you take advantage of higher rates today while still having regular access to some of your money.

Types of CDs and when to use them

Again, it can’t be overstated that not all CDs are the same. Just as some calculate interest differently than others via compounding structures, others will have different features altogether. Below is a list of some of the more popular CDs that you might come across.

How to choose the best CD for you

Not all CDs are created equal, and the most important CD is the one that fits your own plans. Before locking in a term, it’s worth comparing how each account handles penalties, rate changes, and minimum deposits. Below are 4 key factors you should be looking at before you choose a CD.

1. Match the term to your timeline

Make sure you know when you’ll need your cash, and choose a CD term that aligns with that timing. For example, if you’ll need money for a condo deposit in 8 months, a 6-month CD might be a good fit. If your timing is uncertain, consider using a CD ladder or a no-penalty CD for more flexibility.

2. Look at the rate outlook

If you, like many others, are expecting rates to drop, then why not lock in solid rates or a longer timeline? If you think rates may rise, shorter terms (or a ladder) preserve the option to reinvest higher later.⁵

3. Read the penalty policy

Always read the fine print, and always read the terms of the penalty. Two similar APYs can have very different penalties, and a harsher penalty makes a CD much less forgiving if plans change.

4. Confirm minimums and interest crediting

Some CDs require a minimum opening deposit; some credit interest monthly to the CD (compounds), while others pay out (no compounding). As mentioned in the beginning of this article, this methodology for compounding can affect overall returns. 

Are CDs worth it in 2026?

Look, everyone wants a high yield with as little risk as possible. Although CDs don’t deliver the most amazingly high yields possible, for a risk-free investment backed with federal protection, the yields are quite good. CDs are a great thing to have as part of a portfolio, particularly for financial goals that might be on short or medium-term horizons. For example, if someone is saving for a down payment on a house within the next 9 to 18 months, CDs can be a solid choice.

The tradeoff is liquidity; how long can you stand to have your money locked up and not be able to touch it without a penalty? This is why options are important, and that includes considering CD laddering to give you access to cash flow while continuing to earn a decent return on at least some of your cash. One thing is certain: interest rates won’t remain this high forever, so if there is a solid CD with a solid rate that compounds the right way, consider getting on board with it sooner rather than later.

Frequently asked questions

Can I lose money in a CD?

No, or at least it’s super difficult to lose money on a CD. As long as your CD is issued by an FDIC-insured bank (or NCUA-insured credit union) and your total deposits stay within the $250,000 coverage limit per institution, your principal is protected. The only “loss” you might face is an early withdrawal penalty.

Are CD rates fixed for the full term?

Yes. Once you open a CD, the APY you lock in stays the same until maturity, regardless of what happens with the Federal Reserve or market rates. This predictability is a major advantage for savers who want certainty about their returns. That being said, it also means you won’t benefit if rates rise after you open your CD, unless you choose a bump-up or step-up CD that allows for a rate increase mid-term.

Can I open more than one CD at the same bank?

 Yes, and it’s quite common. Many people open multiple CDs at the same bank as part of a CD ladder or to take advantage of different terms. Just keep in mind that FDIC insurance covers up to $250,000 per depositor per insured bank, so staying under that limit keeps your deposits fully protected.

What happens when my CD matures?

When a CD reaches its maturity date, the bank usually gives a short grace period, usually around 7 to 10 days, to decide what to do next. The funds can then be withdrawn, renewed at the current rate, or transferred to another account.
