We think it's important for you to understand how we make money. It's pretty simple, actually. The offers for financial products you see on our platform come from companies who pay us. The money we make helps us give you access to free credit scores and reports and helps us create our other great tools and educational materials.

Compensation may factor into how and where products appear on our platform (and in what order). But since we generally make money when you find an offer you like and get, we try to show you offers we think are a good match for you. That's why we provide features like your Approval Odds and savings estimates.

Of course, the offers on our platform don't represent all financial products out there, but our goal is to show you as many great options as we can.

If you like the idea of better service and lower fees and interest, you may be better off with a credit card from a credit union than from a major card issuer.

We picked our favorites based on their standout features for a variety of consumers.

Best for low interest: Lake Michigan Credit Union Prime Platinum Visa® Card

Here’s why: The card’s lowest variable APR on purchases, cash advances and balance transfers starts at 6.25%. (Note that the issuer says you’ll have to contact the them to know what the maximum rate could be, although the max is stated at 14.25% in the card’s recent terms and conditions).

Who qualifies: Lake Michigan Credit Union membership is primarily for residents in certain areas of Michigan and Florida, but residents of other states can also join. Here are the criteria.

  • You live, work or worship anywhere in Michigan’s lower peninsula.
  • You live, work or worship anywhere in Florida.
  • You’re an immediate family member of a current member.
  • You live in a state besides Michigan or Florida and donate $5 to the ALS Foundation.

The card doesn’t offer any rewards or any other significant perks, but a low APR can make your life easier if you think you might carry a balance from month to month. You also don’t have to worry about paying an annual fee or a balance transfer fee. Note that this card has a foreign transaction fee of 1% and a cash advance fee of 3%.

Getting a lower APR for the Lake Michigan Credit Union Prime Platinum Visa® Card can depend on having healthy credit. The credit union says the card’s lowest rate is based on credit scores of 760.

Best for building credit: DCU Visa® Platinum Secured Credit Card

Here’s why: You can get a relatively low APR, with relatively few fees and a path to building credit.

Who qualifies: There are four primary ways you can qualify to become a Digital Federal Credit Union member.

  • Living, working, worshipping or attending school in an eligible community in Massachusetts or Georgia
  • Working for or retired from an eligible employer
  • Belonging to an eligible organization
  • Being an eligible family member of a current DCU member

The DCU Visa® Platinum Secured Credit Card offers a low 11.50% variable purchase, balance transfer and cash advance APR for all cardholders who get approved. You also won’t pay an annual fee or a transaction fee for cash advances or balance transfers, and there’s no foreign transaction fee.

That said, this is a secured card, which means you’ll need to hand over a security deposit before you’re given a credit limit. Your credit limit will be equal to your deposit, so keep that in mind when you consider this card.

Best for balance transfers: Navy Federal Credit Union Platinum Card

Here’s why: This card offers you time to pay off an existing balance with no balance transfer fees.

Who qualifies: 

  • Active duty, retired or veteran service member in any branch of the U.S. military
  • Immediate family members of an active-duty, retired or veteran service member
  • Department of Defense civilian personnel, including employees, U.S. government employees and contractors assigned to DOD installations
  • DOD retirees and annuitants

When applying for membership, be ready to supply your Social Security number, driver’s license or government ID; home address; and banking account and routing number or a credit card number.

If you request a balance transfer within 30 days of opening the Navy Federal Credit Union Platinum Card, you’ll get an intro APR of 0% on balance transfers for 12 months. After the intro period, the card’s standard variable APR of 5.99% to 18% will apply. The card also offers no balance transfer fees, making it a good fit for those who are looking to pay down a larger balance over time.

On top of that offer, the Navy Federal Credit Union Platinum Card also comes with no annual fees, no foreign transaction fees and no cash advance fees.

Just keep in mind that while this card offers an intro balance transfer APR, it does not include an intro APR offer for purchases. But with the chance to qualify for a low APR overall, this card still makes it into our top picks. For similar options, check out our list of the best credit cards for military personnel.


How we picked these cards

Many credit unions serve local communities only, limiting who can apply to people who live in a certain region. As a result, we limited the scope of our research to credit unions that make it possible to become a member regardless of where you live in the United States.

We also made our picks based on features that provide enough value for different types of cardholders to compete with some of the best credit cards from major card issuers. That includes a cash back card with a tough-to-beat rewards rate and cards with impressively low interest rates and few fees.

How to make the most of credit union credit cards

If you plan to get a credit union credit card, take the opportunity to look at other benefits you might get as a member, such as higher deposit rates on checking and savings accounts and lower interest rates on loans.

As we noted above, we limited this list to cards from credit unions with attainable membership requirements for people around the United States. For that reason, we recommend taking a closer look at your local credit unions, as they may be more focused on the community you live in and provide better service for your needs.
