The certificate of deposit remains a straightforward option for savers who want a guaranteed return over a fixed period. As of May 27, 2026, top short-term offers for a 12-month CD reach as high as 4.05% APY, while the national average sits much lower at around 1.55% according to the FDIC. A certificate of deposit locks your principal for a set term in exchange for a stated yield, which can make planning easier when you expect to need the money within a year or when you want protection from falling rates.
Rates have been relatively stable in recent weeks, which makes this a reasonable moment to consider securing a rate for the coming 12 months. Current competitive offerings include a 4.05% APY jumbo CD from Credit One Bank with a $100,000 minimum, a 4.00% APY 12-month CD at Live Oak Bank with a $2,500 minimum, and Finworth (a division of INSBANK) at 3.95% APY with a $50,000 minimum. Credit unions such as Navy Federal offer a regular 12-month share certificate at 3.70% APY with a $1,000 minimum and a jumbo option at 3.75% APY for $100,000. Alliant Credit Union lists competitive short-term and jumbo rates in the mid 3.70%–3.80% APY range.
How a 12-month CD actually works
A 12-month CD simply pays a fixed interest rate for a one-year term in exchange for leaving your deposit untouched until maturity. Most institutions enforce an early withdrawal penalty if you take money out before the term ends; a common penalty is roughly 90 days of interest. Because the rate is fixed for the term, a CD provides rate protection if market yields decline, and it offers a predictable payout for budgeting. For example, a $25,000 CD at 4.00% APY would produce about $1,000 in interest over 12 months, compared with roughly $385 using the national average for short-term yields.
Practical uses for a 12-month CD
Savers often choose a 12-month CD for clear, near-term objectives such as upcoming tuition payments, a planned wedding, or a down payment scheduled within a year. The product is also useful when you want to lock a decent guaranteed return while keeping the horizon short. Another common tactic is a CD ladder, where you stagger maturity dates across multiple terms to preserve liquidity while capturing higher rates on longer tranches. This approach blends access to cash with some yield enhancement compared with keeping everything in a single short-term account.
Key factors to check before you open a CD
Not all CDs are identical, so verify a few points before you commit funds. Confirm the minimum deposit required to open the account and whether the best APY is tied to a jumbo balance. Read the fine print on the early withdrawal penalty and the institution’s renewal policy, since many CDs auto-renew at maturity. Make sure the bank or credit union is covered by FDIC or NCUA insurance, which protects up to $250,000 per depositor, per institution. Also check whether the rate is locked at the time of funding, and that the provider offers convenient online access and e-statements if you prefer digital management.
Additional considerations
Compare accessibility and customer experience as part of your decision. Some institutions have attractive headline APYs but require large minimums or limit how you can add funds during the term. If you might need liquidity, review whether the CD offers a short grace period at maturity—typically seven to ten days—to withdraw or change terms without penalty. Also keep tax treatment in mind: interest from CDs is subject to federal income tax and in many states to state tax as well.
How we gather and validate rates
Our editorial process involves daily rate checks across an array of banks and credit unions to ensure the information reflects publicly disclosed yields. We confirm each APY against official rate disclosures and regulatory filings and include only institutions insured by either the FDIC or the NCUA. Rankings are based on yield, accessibility, and the overall customer experience; editorial judgment is independent of any referral agreements. While we may receive a referral fee when readers open accounts through certain links, our recommendations rest on objective criteria rather than compensation.
Bottom line and quick answers
Short-term 12-month CDs remain a secure way to earn a fixed return, particularly when national averages are well below top offers. Yes, CDs are federally insured up to $250,000; yes, early withdrawal typically costs about three months’ interest; and yes, interest is taxable. If rates are near cycle highs, locking a one-year rate can make sense for many savers who want a predictable return with limited term exposure. Review minimums, penalties, and renewal terms before you fund the account to ensure it fits your cash-flow plans.
