Credit Union Certificates of Deposit 2025

Credit union certificates of deposit (“CDs”, also commonly called “time deposits” at credit unions) are contract-based and time-based savings vehicles that are offered by credit unions. In return for agreeing to keep your money tied up with the credit union for a given time period, you earn a fixed rate or return that cannot change over the course of that period. Should you need your money before the expiration of the contractual period, the penalties for early withdrawal can be severe. Not all credit unions even offer early withdrawal from CDs; many that do offer it maintain the right to deny it in their fine print. It therefore is important to fully understand the terms of any time-based deposit that you enter with a credit union. Read this article for further detail on early withdrawal penalties.

NCUA Insurance

Most, but not all, credit unions listed on BestCashCow are insured by the National Credit Union Administration (NCUA). You should confirm that the credit union that you are working with is NCUA-insured by visiting that institution’s BestCashCow page (NCUA coverage is detailed on the overview tab). The NCUA insures each named individual's deposits to $250,000 for all accounts at the credit union within ownership class. The rules are very similar, but not identical, to those for FDIC insurance. You should always stay within NCUA insurance limits.

BestCashCow strongly recommends that you deposit money only in NCUA insured credit unions and that you stay within insured limits. If you are considering depositing over $250,000 at a single NCUA-insured credit union across products (share certificates, time deposits, etc.) or across types of ownership (individual, joint, etc.) you should use the NCUA’s Share Insurance Toolkit in order to be sure that you are not exceeding coverage limits.

Is there any difference between a time deposit offered by a credit union and a CD account offered by a bank?

The difference is mainly one of terminology. But, you should always completely understand the terms of a time deposit or CD before you enter it, paying careful attention to the early withdrawal penalties. A reasonable early withdrawal penalty for a 1-year CD or time deposit is 3 months, and a reasonable early withdrawal penalty for a longer term CD is 6 months.

Does the small amount of interest gained on a time deposit make sense given the fact that I am losing access to my capital (liquidity)?

This is a decision that depends on your own specific circumstances, your needs for cash, and other investments that you may wish to pursue over the period of your time deposit or CD. The premium in a one-year CD is very small, with the premium of longer-term CDs being a little wider. A small difference in compounding interest can make a large difference over long period of time.
