Wealth Management FAQ: Money Market Account vs. Share Certificate: What's the Difference?
09/09/2026
What's the difference between a money market account and a Share Certificate at a credit union?
A money market account keeps your money accessible while earning dividends. A Share Certificate locks in a fixed rate for a set term in exchange for higher earnings. The right choice depends on whether you need flexibility or are willing to set the money aside.
The Key Difference: Access vs. Rate
Both accounts are safe, insured savings options — but they serve different purposes depending on your timeline and how often you might need the funds.

Flexible — withdraw when needed |

Fixed dividend rate locked in at opening |
|
Good for emergency funds and short-term savings |
Good for money you will not need for 6 months or more |
|
Rate may change with market conditions |
Rate stays the same regardless of market changes |

No penalty for withdrawals |
Early withdrawal may result in a dividend penalty |
When a Money Market Makes More Sense
• You are building or maintaining your emergency fund.
• You want your savings to earn more than a basic savings account without giving up access.
• You are saving toward a goal with a flexible timeline, such as a home down payment or car purchase.
When a Share Certificate Makes More Sense
• You have money you know you will not need for at least 6 months.
• You want a guaranteed return without any exposure to market fluctuation.
• You want to earn the highest available rate on a portion of your savings.
Can You Have Both?
Yes — and many members do. A common approach is keeping 3 to 6 months of expenses in a money market account for liquidity, then placing additional savings into a Share Certificate to maximize the return on money that does not need to stay liquid.
Capitol Credit Union offers both options. A team member can walk you through current rates and terms with no obligation.
