How Credit Union Money Market Accounts Work

Money market accounts (MMAs) are a smart way to earn higher dividends on your savings while maintaining easy access to your money.

Credit unions often offer some of the best money market rates available — with lower fees and more flexibility than big banks.

If you’re deciding between a savings account, a CD, or a money market account at your credit union, this guide explains exactly how MMAs work, how dividends are paid, and when they make the most sense.

1. What Is a Credit Union Money Market Account?

A money market account (called a Money Market Share Account at credit unions) is a hybrid between:

• A savings account (safe, insured, liquid)
• A checking account (some withdrawal flexibility)
• A CD-style product (higher yields, tiered rates)

You earn higher dividends in exchange for keeping a larger balance, while still being able to access your money when you need it.

MMAs are ideal for:

• Emergency funds
• Short-term savings
• Large balances you want to grow safely
• Business reserves
• Parking money while exploring long-term options

2. Why Credit Unions Offer Better Money Market Rates

Credit unions are not-for-profit, so they return earnings to members — not shareholders. This often results in:

• Higher dividend rates
• Lower balance requirements
• Fewer fees
• More consumer-friendly tier structures

Many top-yielding MMAs in the nation come from credit unions, especially community and regional CUs.

3. How Dividends Work in a Money Market Account

Credit union MMAs typically pay tiered dividends, meaning:

• Higher balance = higher rate
• You earn based on the tier your balance falls into

Example tier structure:

• $0–$2,500 → 0.10%
• $2,500–$10,000 → 0.25%
• $10,000–$25,000 → 0.50%
• $25,000+ → 1.00%

Dividend crediting usually happens:

• Monthly
• Based on average daily balance
• Automatically added to your account

Like all credit union accounts, MMAs are:

• NCUA insured up to $250,000
• Sometimes privately or dually insured above that

4. Withdrawal & Access Rules

Unlike CDs, money market accounts give you flexible access:

You can usually:

• Withdraw money anytime
• Transfer to checking or savings
• Write a limited number of checks (if your CU offers MMA checks)
• Use digital banking for transfers
• Access funds at a branch

Reg D Limits (The Old Rule)

Before 2020, MMAs were limited to 6 monthly withdrawals due to Regulation D.

This rule was suspended, but many credit unions still use internal limits of:

• 6 free withdrawals per month
• Fees for excessive withdrawals

Always check your CU’s specific policies.
