Key takeaways

• HYSAs offer flexible access to cash with variable interest rates and typically no withdrawal penalties.
• CDs lock in funds for a set term and may provide more certainty around interest earnings.
• People can use both accounts to meet a variety of financial goals.

Savers and investors may be wondering how to make the most of savings and try to outpace rising inflation. Two options come to mind for building interest: a CD vs. high-yield savings account.

Both a certificate of deposit and a HYSA use the power of compounding to build on either a fixed or variable interest rate, though getting the most value from the account may depend on your time horizon and how much flexibility you need.

Generally, a HYSA is preferred for liquid cash reserves that might need to be tapped quickly, such as an emergency fund. With fixed terms and more stringent withdrawal rules, a CD could fit well for planned cash needs. Both types of accounts can be used for short- and long-term financial goals.

Americans had an average cash savings balance of $39,262 in April 2026, according to Empower Personal Dashboard^TM data. Both CDs and HYSAs can be lower-risk tools for savers to earn interest on their cash, though some key differences stand out.

What is a HYSA?

A high-yield savings account (HYSA) is a savings deposit account that earns a higher-than-typical amount of interest, known as the annual percentage yield (APY). The APY shows the total amount of interest you can expect to earn during the year, expressed as a percentage.

But that percentage isn’t set in stone. HYSAs are variable rate; the APY can change over time as determined by the financial institution offering the account. The average savings account interest rate was 0.38% as of May 18, 2026, while high-yield savings account APYs would typically be higher than the average.¹

In addition to rate changes, financial institutions can set requirements around direct deposits or minimum account balances. It’s important to review the account disclosures carefully to ensure you’re able to follow the rules and maximize the value of the HYSA.

High-yield savings accounts typically don’t have withdrawal caps — limits on how many transactions you can make per month — so they can be a good source of liquidity for short-term savings. However, institutions may still set their own transaction policies or fees.

What is a CD?

A certificate of deposit (CD) is also a deposit account, though it has a set term and maturity date. These can be opened online or in-person at banks, credit unions, and other types of financial institutions.²

A CD typically pays a fixed rate of interest for the term, though early withdrawals can result in a penalty unless the account disclosures deem it a no-penalty CD. At the end of the term, you receive back your original deposit plus interest accrued.

A CD term can vary in length, such as one month, three months, six months, one year, or longer. Make sure to get all the account details, since reaching the maturity date doesn’t necessarily mean the bank will close your CD; some accounts renew automatically, possibly with a different interest rate.

Selecting a CD term that best fits when you’d need the funds helps avoid paying an early withdrawal penalty.

CD vs. HYSA comparison

High-yield savings accounts and CDs can meet different financial needs:

The accounts are similar and overlap when it comes to additional factors important for savers:

• Deposit insurance: Both CDs and high-yield savings accounts are eligible for deposit insurance at financial institutions backed by the Federal Deposit Insurance Corporation (or National Credit Union Association for credit unions). Deposits are federally insured for up to $250,000 per depositor, per bank, per ownership category.³
• Taxes: Interest received from HYSAs and CDs is treated as taxable interest income.⁴ Savers will receive a 1099-INT or 1099-OID tax form for amounts of $10 or more.⁵
• Rate shopping: APYs matter for both deposit accounts, and financial institutions can shift their rates continually. Check around at physical and online financial institutions to see which rates are the best fit, along with any additional requirements.

When a HYSA may be the better choice

The flexibility of a high-yield savings account can be a greater benefit for people with shifting financial priorities or who just want more peace of mind knowing they can access their money without a potential penalty.

Short-term money goals can be a good fit for a high-yield savings account.

• Cash that’s needed in the next weeks or months: Everyday expenses like rent or groceries could fall into this category, and savers with less predictable income streams can benefit from the HYSA not having transaction limits.
• Money that may need to move quickly: Payments for credit card bills or to reimburse someone could need to be withdrawn with shorter notice.
• A sinking fund: A dedicated savings pot for predictable expenses that you know are coming — like travel or entertainment tickets — could be housed in a HYSA.
• An emergency fund: Empower research found that Americans have a median of $500 saved for emergencies.

Make sure to stay on top of a HYSA, as the APY could change, especially if a promotional rate expires or if you no longer meet certain requirements.

When a CD may be the better choice

A set schedule and rate lock can be important factors that could make a CD smarter move for your savings goals. A CD works best for money that aligns with how the account is set up:

• The money is needed at a certain time: This “deadline” can help decide on the most appropriate CD term.
• Withdrawals won’t be necessary before maturity: Because CD deposits are “locked in” until the maturity date, it may be wise to set aside only what you can do without for the short term.
• You want a specific rate for a defined amount of time: Some CDs may offer variable rates after a certain period, though compared to HYSAs, there is more certainty around the initial APY with a CD.
• You can keep up with penalty disclosures and renewal terms: Before opening a CD, it’s important to understand what can happen if you need to withdraw your money before the maturity date, or if you want to renew your CD after the maturity date.

End-of-year holiday shopping is a good example of when a CD could be a helpful financial tool. By setting aside money and locking the funds into a CD earlier in the year – say, for a 3- or 6-month term, so that the maturity date aligns with shopping season – savers can avoid spending the money prematurely while earning interest on their gift fund in the meantime.

Some savers choose to have multiple CDs, in what’s called a CD ladder or CD laddering. This strategy involves opening multiple CDs with different terms, so that the accounts mature at different times.

This allows a person to lock in a variety of APYs while still having access to their cash at expected intervals. At the same time, their deposits can continue accumulating interest over a longer period. However, keep in mind that each CD can have a different APY and a longer term doesn’t necessarily result in a higher rate.

Savers using individual CDs or a CD laddering strategy need to keep track of the details. A CD tracking spreadsheet or similar checklist should include:

• When each CD was opened
• Original amount deposited
• Interest rate — and whether it’s fixed or variable (and for how long)
• When interest is paid (monthly, every six months, etc.)
• How the bank distributes the interest (electronic deposit, check, etc.)
• CD maturity date

Frequently asked questions about CDs and HYSA

What makes a CD “high yield”?

A high-yield CD is a certificate of deposit that pays a competitive APY relative to other CD offers. The term “high yield” does not mean the account is an entirely different product; rather, it is a label that may help differentiate these CDs from others.

When shopping for high-yield CDs, make sure to verify each account’s specifics, such as APY, term, any minimum deposit requirements or withdrawal penalties, and whether it’s at a federally insured institution.

Can someone use both a CD and a high-yield savings account?

Yes, some people keep emergency funds in a HYSA while using CDs for planned expenses or longer-term savings goals with defined timelines.
