CD rates today: compare the whole offer, not one number

A certificate of deposit rate is only useful with a timestamp and a set of terms. The attractive number on a comparison page may apply to a narrow maturity, require a large opening deposit, or disappear when the CD renews.

That makes "CD rates today" a shopping task rather than a single national answer. Check offers from banks and credit unions you can actually use, then confirm the terms on the institution's own site before opening an account. This guide does not quote a market rate because those numbers change and availability can depend on location, balance, and account type.

Use the CD and Treasury Yield Calculator to compare the amounts you find. It can estimate interest and an after-tax result from your inputs. The calculator cannot tell you whether the maturity date or withdrawal rules fit the job you have in mind for the money.

Compare APY before comparing the interest rate

Banks usually show both an interest rate and an annual percentage yield, or APY. They are related, but they are not interchangeable.

The interest rate is the rate applied to the deposit. APY expresses how much the account would earn over a year when compounding is included, under the disclosed assumptions. Two CDs can show the same interest rate and different APYs if they compound differently.

For that reason, APY is the cleaner first comparison when the deposit amount and term are the same. Regulation DD requires account disclosures to identify both the interest rate and APY. The disclosures also cover compounding and crediting frequency, minimum-balance rules, fees, and features of time accounts.

APY does not fix a mismatched comparison. A six-month CD and a two-year CD tie up money for different periods. Their APYs put earnings on an annual basis, but they do not tell you what rates will be available when the shorter CD matures or what cash needs may appear during the longer term.

Make sure the quoted rate is still available

A rate table can go stale quickly. Record four details while shopping:

  • the APY;
  • the date or time the institution says the rate is effective;
  • the maturity term;
  • the minimum deposit needed to receive that APY.

Then open the institution's current disclosure rather than relying only on a search result, ad, email, or comparison site. Regulation DD allows an institution responding to a request for written disclosures to provide a rate and APY offered within the previous seven calendar days if it identifies the effective date and gives a phone number for current rate information. A properly dated disclosure can therefore be compliant without being a live quote at the moment you read it.

Take a screenshot or save the disclosure before funding the CD. After the account opens, check the confirmation for the deposit amount, rate, APY, opening date, and maturity date. If any item differs from the offer you expected, contact the institution while the record is fresh.

Match the term to the date you need the cash

A CD is a savings account with a time commitment. The Consumer Financial Protection Bureau's CD explainer says depositors generally agree to leave the money in place for a specified period and may pay a penalty for withdrawing early.

Start with the spending date, not the highest APY on the screen. Money reserved for a tuition bill in nine months does not fit comfortably in a one-year CD merely because the one-year rate is higher. The early withdrawal penalty could erase the apparent advantage, and the institution may limit partial withdrawals.

The same issue applies to emergency savings. A CD can hold a later layer of a large cash reserve, but the first dollars needed for rent, repairs, or an insurance deductible usually need quicker access. The Emergency Fund Calculator can help separate an immediate cash target from money that may be available for a fixed term.

If there is no known spending date, compare several sensible maturities rather than defaulting to the longest one. A longer commitment does not always pay a higher APY. The shape of bank funding needs and the interest-rate environment can produce offers where a shorter CD pays more.

Read the early withdrawal penalty in dollars

"Penalty applies" is not enough information. You need to know how the institution calculates it and whether the penalty can reach principal.

Regulation DD requires the account disclosure to say that a penalty will or may apply, explain how it is calculated, and state the conditions that trigger it. A penalty might be described as a number of days or months of interest. The details vary, including which rate is used, whether the institution takes earned interest first, and whether it permits a partial withdrawal.

Convert the rule into a rough dollar amount for the deposit you plan to make. Then compare that amount with the extra interest offered over a more accessible account. A small APY advantage can be a poor trade if one unexpected withdrawal costs several times the extra earnings.

Do not assume the penalty is the only obstacle. The agreement may prohibit partial withdrawals, require the entire CD to close, impose a waiting period after opening, or make early access subject to the bank's consent except in specified cases. Read the actual deposit agreement before sending money.

Some institutions offer no-penalty CDs. The label still needs inspection. Check when withdrawals become available, whether only one full withdrawal is allowed, and what happens to the account afterward. Flexibility can come with a lower APY than a standard CD of a similar term.

Check the minimum deposit and balance rule

The advertised APY may require a specific opening deposit or balance tier. A rate shown for a $100,000 balance does not describe what a $5,000 deposit will earn.

Regulation DD requires disclosure of any minimum balance needed to open the account, avoid a fee, or obtain the stated APY. Tiered-rate accounts must disclose the rate and corresponding APY for each balance level.

Also distinguish a minimum from a maximum. Promotional CDs sometimes cap how much can receive the special APY. If the deposit exceeds that limit, the excess may earn another rate or may not be accepted under the offer.

A bonus can complicate the comparison. Treat it separately from APY unless the disclosure clearly includes it. Confirm the balance and holding-period requirements, when the bonus arrives, and whether closing early causes the institution to reclaim it.

Find the maturity and renewal instructions

The maturity date is when the agreed term ends. What happens next can matter as much as the opening APY.

Many CDs renew automatically. The new CD may have the same term but whatever rate the institution offers at renewal, not the rate on the old CD. Regulation DD requires the disclosure to say whether the account renews automatically and whether a grace period is provided. If there is a grace period, the disclosure must state its length.

Put two reminders on a calendar: one shortly before maturity and another on the maturity date. Before the grace period closes, compare the renewal offer with current alternatives and decide whether to renew, change terms, or move the cash.

Missing the window can lock the deposit into another term. Closing the renewed CD afterward may trigger an early withdrawal penalty. The old CD's strong rate does not make an automatic renewal strong too.

Check how the institution delivers maturity notices. An email can land in spam, and a paper notice can go to an old address. Keep contact details current and do not rely on the notice as your only reminder.

Confirm what deposit insurance covers

A CD at an FDIC-insured bank is a deposit account. The FDIC says its insurance covers certificates of deposit and is automatic for eligible deposits at insured banks. Coverage is at least $250,000 at each insured bank, but the full calculation depends on the depositor and account ownership category.

A credit union CD is usually called a share certificate. Federally insured credit unions use National Credit Union Share Insurance Fund coverage rather than FDIC insurance. Verify the institution and coverage instead of trusting a logo copied onto a rate-listing page.

Bank name alone can be misleading. Several brands may be divisions of the same insured bank, so splitting money between them may not create separate coverage. Conversely, different ownership categories can receive separate treatment under the insurance rules. Use the FDIC's BankFind and insurance estimator, or the NCUA's equivalent tools, when balances approach coverage limits.

A brokered CD needs another check. It may be issued by an insured bank, but it is purchased through a brokerage account and can behave differently before maturity. If it is sold on a secondary market, its price can be above or below the original deposit amount. Review the issuer, insurance allocation, call provisions, brokerage fees, and what happens if the brokerage relationship changes.

Decide whether a CD ladder solves a real problem

A CD ladder divides money among several maturity dates. One simple version places equal amounts in CDs that mature at regular intervals. As each CD matures, the cash can be spent or moved into a new longer-term CD.

The appeal is access. Only part of the money is committed to the longest remaining term, and another maturity is always getting closer. The cost is administration: more accounts, more renewal dates, and more chances to miss a grace period.

A ladder does not guarantee a better return. If rates fall, new rungs may earn less. If rates rise, the older rungs remain at their original rates until maturity. Build one because staggered access suits the expected cash needs, not because "ladder" sounds like a strategy that must outperform.

Compare CDs with Treasury bills on the same basis

Treasury bills are not bank deposits. They are short-term U.S. government securities sold at a discount or at par, and their quoted yields do not always use the same convention as a bank APY.

Taxes differ too. CD interest is generally subject to federal and state income tax. Interest on Treasury marketable securities is subject to federal income tax but exempt from state and local income tax. That distinction can change the after-tax comparison for someone subject to state income tax.

Our Treasury bills versus CDs guide covers yield conventions, taxes, insurance, early access, and maturity mechanics. Enter the actual CD APY and Treasury investment rate you find in the CD and Treasury Yield Calculator rather than treating two headline percentages as identical.

Liquidity is different as well. A bank CD uses the early withdrawal terms in its agreement. A marketable Treasury bill can be sold before maturity through a broker, but its price may move and settlement takes time. TreasuryDirect securities have their own transfer procedures. Neither instrument is automatically the better home for every short-term dollar.

A compact CD comparison checklist

Before opening a CD, write down:

1. Institution name and the actual insured bank or credit union behind the offer. 2. Effective date of the rate, interest rate, and APY. 3. Opening deposit, balance tier, and any maximum for the offer. 4. Term, opening date, and maturity date. 5. Compounding and interest-crediting schedule. 6. Early withdrawal formula and partial-withdrawal rules. 7. Automatic-renewal policy and grace-period length. 8. Callable, stepped-rate, variable-rate, or bonus features. 9. Deposit-insurance treatment for the amount and ownership category. 10. The job the money must do and the earliest date it may be needed.

This list takes longer than sorting a rate table from highest to lowest, but not much longer. The highest APY among CDs with the wrong term or an expensive exit is not the highest useful return.
