Bank vs credit union for a business loan

Two different kinds of institution

A bank is a company owned by shareholders, lending deposits to earn a return on its capital. A credit union is a cooperative owned by its members: not-for-profit, exempt from federal income tax, and limited to lending to people and businesses within its field of membership. Both take insured deposits, both are examined by federal or state regulators, and both make business loans. What differs is how much of their balance sheet business lending can take, what kind of business lending they are built for, and what else they can do for an operating company.

The member business lending cap

Federal law limits the total amount of business loans most credit unions may hold to the lesser of a multiple of their net worth and a fixed share of their total assets. For a credit union with a large consumer business and modest capital, the cap can be the binding constraint on how much it lends to businesses at all. When it is close to the cap, it becomes selective in ways that have nothing to do with the borrower: it may favor its longest-standing members, prefer smaller loans, or decline new business lending for a period.

Several things fall outside the cap. Credit unions with a low-income designation, and certain credit unions chartered or historically focused on business lending, are exempt. Some loan types are excluded, such as loans secured by the member's home. Loans backed by a federal guarantee, including SBA's, receive favorable treatment. That is one reason some credit unions use SBA programs actively: the guaranty helps both their risk and their room under the cap.

A borrower cannot see how close a credit union is to its cap, but it shows up in behavior. A credit union that was eager for your building loan may be unable to offer a line of credit or an increase a year later. Ask directly how much room the institution has for business lending and whether it has ever paused.

A credit union near its cap can pull back for reasons unrelated to your business. Ask how much room it has before you rely on it for growth.

Hold size, participations and who really underwrites

Every lender limits how much it will lend to one borrower, under a legal limit and, more tightly, its own policy. Most credit unions have smaller balance sheets than regional banks, so the amount they will hold on one relationship is usually smaller. A credit union that likes a larger loan commonly participates it: it keeps part and sells the rest to other credit unions. Many also rely on a credit union service organization (a shared back office owned by several credit unions) to underwrite and service commercial loans.

For the borrower, that has two effects. The decision may be made by an underwriter who has never met the business, applying a shared policy. And every later change, such as an extension, a covenant waiver or a new advance, may need the agreement of the participants. That is manageable on a stable real estate loan. It is slower and less predictable on an operating company whose needs change every year. The same issue arises with bank syndicates, but at the loan sizes most private companies need, a single bank usually holds the whole loan.

Where a credit union can be the better lender

Credit unions do not pay federal income tax and do not owe shareholders a return, and many run lean commercial lending teams. On the loans they are built for, that can translate into lower rates and lower fees than a bank would quote:

• A smaller owner-occupied building, with solid equity and a long-standing owner. This is the core of most credit unions' business lending. It is worth comparing against both a bank mortgage and an SBA 504 structure; see SBA 504 vs a conventional commercial mortgage. Some credit unions act as the first-lien lender in 504 projects.
• Vehicles and equipment, where the collateral is standard and easy to value. Compare also equipment financing vs SBA 7(a).
• A small business whose owners already bank there personally. The relationship is real at a credit union, and a member with a long history often gets a hearing a bank would not give a company of the same size.
• Some SBA loans. A credit union active in SBA lending can be a good 7(a) lender for a smaller acquisition or refinance, with the same SBA rules as any other lender: coverage of at least 1.15x, and from 1 October 2026 at least 1.25x on historical results for a change of ownership.

Where a growing company outgrows it

A company with several million in revenue usually needs more than a loan against its building. It needs a package: an operating line, a term loan for equipment or an acquisition, and the cash management to run payables and collections. This is where banks, and community and regional banks in particular, usually fit better.

• Cash-flow lending. Acquisitions and recapitalizations are sized on earnings, not collateral. Senior cash-flow lenders to lower-middle-market companies commonly lend 2x to 3.5x EBITDA, with covenants and monitoring built for it. Few credit unions lend against goodwill outside SBA programs. See how much debt a business can carry.
• Working-capital lines and ABL. A line sized on a borrowing base, with borrowing base certificates and field exams, needs systems and staff that most credit unions do not keep. Asset-based lenders typically advance 80% to 90% of eligible receivables; that product lives mainly at banks and non-bank ABL lenders. See bank vs non-bank ABL.
• Treasury services. Lockbox, positive pay, ACH origination at volume, sweep accounts, international wires and letters of credit are standard at commercial banks and uneven at credit unions. A lender that holds the operating accounts sees collections directly, which is part of how it gets comfortable with a line.
• Room to grow. A company that doubles needs a lender whose hold limit, and whose cap, can double with it.

None of this makes a credit union a bad lender. It makes it a specialist in a narrower set of loans. The difference between community and larger banks is covered in community bank vs national bank, and the wider field in types of lenders in the lower middle market.

Membership, relationship and moving your accounts

A credit union can lend only to members, so the business, and often its owners, must join, usually by opening an account. Eligibility depends on the credit union's field of membership, which may be defined by geography, employer or association. Most will expect the business's deposits as part of the relationship.

Banks rarely require membership, but most expect the operating accounts once they make a line of credit or term loan, and some write it into the loan agreement as a covenant. Before splitting lenders, for example a building loan at a credit union and a line at a bank, check each lender's liens and cross-default terms: both will usually want the business's assets, and they must agree on who holds what. See intercreditor agreement, blanket liens and new financing and moving loans to a new bank.

How to decide

Start from what the business needs over the next few years, not from the single loan in front of you. If the need is one well-secured real estate or equipment loan, a credit union belongs on the list and may win on price. If the need is an operating relationship, including a line, a term loan, perhaps an acquisition, and treasury, compare community and regional banks first, and bring in a credit union for the piece it does best.

Either way the file is the same. A term loan starts with a P&L and year-to-date P&L, a balance sheet, a debt schedule and optionally an AP aging; a line adds an AR aging by customer with days outstanding and an inventory report where inventory is in the base. Conventional bank lenders commonly look for debt service coverage of at least 1.25x. Transparent's lender book holds 1,800+ lenders, including 235 writing asset-based loans and lines and 278 writing SBA 7(a) and 504, so one package can be shown to lenders of different kinds and the offers compared on the same file.
