How to choose a bank in Wisconsin

When choosing a bank in Wisconsin, consider what matters most for your financial needs. Wisconsin has 12 FDIC-insured banks headquartered in the state, plus additional out-of-state banks with local branches. Each institution offers different strengths in terms of branch access, product variety, and community focus.

Consider whether branch access matters to you. If you prefer in-person banking, look for institutions with branches near your home or workplace. If you primarily use mobile and online banking, you may want to prioritize digital features and compare interest rates, as online-focused banks often offer higher savings APYs.

All banks listed on this page are FDIC-insured, meaning deposits are protected up to $250,000 per depositor, per insured bank, for each account ownership category (Source: FDIC). Beyond FDIC insurance, compare factors such as monthly maintenance fees, ATM networks, minimum balance requirements, and customer service availability. The CFPB recommends comparing at least three institutions before opening a new account.
