Credit unions are not right for everybody. Here's how they stack up against banks.
Not all credit unions offer the full range of products and services, but most offer enough services to be competitive. Before you decide, make a list of banking services you need and find out which institution will serve you best.
Being a member, as opposed to being a customer, is a significant difference. Since credit unions are nonprofit organizations, they are more focused on the needs of their customers than on meeting the demands of their investors. Not all credit unions operate the same way, and it should be noted that not all savings are passed along to the members. That depends on the people running the show, and on the financial health of the credit union. Banks have the “purchasing” power to undercut small institutions and frequently do.
If you believe that banks are largely responsible for the mess that the U.S. economy is currently in due to predatory lending practices, risky investments, and greedy management, you are not alone. Credit Unions are not huge, faceless, megalith corporations, they are generally small to medium local or industry-specific nonprofits. It's up to you to decide which type of business you prefer to support.
There’s no single answer to the question of credit union vs bank, and fortunately, it is not a permanent decision. If you decide on one and then find you want to switch, it is not that difficult.
