“Margie is friendly and thorough! We’ve been with Affinity CU for many years.

Highly recommend these folks. They know how to take care of their customers.”


Charlie is the greatest.. honestly, everyone there makes banking easy. I always come in with a handful of deposits, but they don’t care. There always given me a hard time and I give it back. Great place, great atmosphere and great people.

Building a better Iowa with you.

Since 1949, Affinity has been working to help members do more with their money. It starts with great rates, low fees and caring personal service – but it doesn’t end there.

Our mission is simple: Building Better Lives.

Community involvement is the heartbeat of that mission. So we sponsor scholarships, raise cash for local scholarships and come together to fund area charities and feed the hungry.

And since every Affinity member is a co-owner, that means when you join us, you’re doing this work too.

It starts with a membership.
