Together we make things better.

Commerce became Summit Credit Union October 1, and we’re thrilled to welcome customers and staff to our co-op team (you’ll fit right in!). See more on this acquisition below – and if you’re coming from Commerce, get to the latest updates and access the online banking login with your same login credentials.

With three whole months of no payments, there’s nothing but new-car bliss ahead! Especially knowing that when those low payments do finally kick in, they’ll totally fit your budget – thanks to that fast, easy preapproval. Apply in 10 minutes or less.

The Truth About Mortgage just featured the biggest mortgage lenders in Wisconsin, putting Summit at the top for both overall mortgage lending and refinancing! Actually, you put us there. Thanks for choosing a local Summit mortgage!

You get more for your money when you join Summit – like 3.40% APY*** for a 13-month certificate (one of the highest rates around)! Just one of many ways we help you earn more for your goals and build wealth. 

Summit Free Checking means no surprise fees, an average savings of $291 a year⁶ and one easy place to manage your account – our mobile app! Pay bills, pay friends (with Zelle®!), move money, even set and track savings goals.

Summit is committed to economic development, and we are proud to partner with the Black Business Hub in South Madison to increase opportunities for entrepreneurs of color.
