A credit union business line of credit works like any other revolving line. The credit union sets a limit, you draw what you need, you pay interest on what you use, and the line opens back up as you repay. The difference is who you borrow from. A credit union is owned by its members, so you have to join before you can borrow.

That one fact shapes most of what follows: who can apply, how big the line can get, and what the credit union will ask for. If you want the full picture on how lines work first, start with my complete guide to a business line of credit or the business line of credit overview. This post stays on the credit union angle.

What a credit union business line of credit is

A credit union is a not for profit financial institution. Members own it and elect a volunteer board, per the NCUA’s MyCreditUnion.gov overview. Like a bank, it takes deposits and makes loans. Unlike a bank, any surplus goes back to members through dividends, lower fees or better loan pricing.

Federal rules treat a business line of credit as a commercial loan. Under 12 CFR 723.2, that covers any loan, line of credit or letter of credit made for a business purpose, including unfunded commitments. In plain terms, the full limit on your line counts, not just what you have drawn. Business credit of less than $50,000 in total to one borrower and related borrowers falls outside that definition.

How it differs from a bank or online line

You have to be a member

Every credit union has a field of membership. You might be eligible through your employer, a family member, a group you belong to, or where you live, work or worship, as MyCreditUnion.gov explains. Many community credit unions serve anyone in a set area. Some business owners join one through their personal account and then open business accounts. Ask about membership before you spend time on an application.

Line sizes can be capped

Credit unions face limits banks do not. Under 12 CFR 723.4, a federally insured credit union covered by the rule must cap commercial loans to one borrower and related borrowers at the greater of 15 percent of its net worth or $100,000. A bit more is allowed if it is fully secured by readily marketable collateral. Some very small credit unions are exempt from that section, and some state chartered credit unions follow an equivalent state rule. On top of that, 12 CFR 723.8 sets a statutory cap on total member business loans tied to 1.75 times net worth, with some exemptions such as low income designated credit unions.

Here is what that means for you. A small credit union may simply not have room for a large line, even if your numbers look good. A larger one may have plenty. The size of the credit union matters more than it does with a bank.

Rate ceilings apply to federal credit unions

Federal credit unions are generally limited to a 15 percent loan rate ceiling by law. The NCUA Board can set a temporary higher ceiling, and in February 2026 it extended the 18 percent ceiling through September 10, 2027, per the NCUA announcement. State chartered credit unions follow their state’s rules. A ceiling is a cap, not a quote. Your price depends on the credit union and your file, and I can’t predict it.

Relationships carry weight

Credit unions tend to lend inside a trade area they define in their loan policy, and they often want to see your deposits with them. If you already bank there, that history helps them understand your cash flow. If you don’t, expect them to ask you to move some accounts over.

What credit unions usually look for

Each credit union writes its own commercial loan policy, so there is no single checklist. For credit unions covered by 12 CFR 723.4, the federal rule requires that policy to cover how deeply the credit union analyzes your financials, your ability to repay, and how it values collateral. In practice, expect them to look at:

Time in business and a track record of revenue.
Business and personal tax returns, plus recent bank statements.
Personal credit for the owners.
Your debt load and whether cash flow can cover a fully drawn line.
Collateral, if the line is secured.
A projection, if your history alone does not support the payments.

For a deeper look at the usual bar across lenders, see my post on line of credit requirements.

Collateral and personal guaranties

Under 12 CFR 723.5, a credit union has to require collateral that fits the size and risk of the loan. If it makes an unsecured line, it must document why other factors offset the risk. It also has to document its reasoning if it skips a full personal guaranty from the owners who control the business. So expect a personal guaranty as the default, and expect a lien on business assets for many lines. I explain the difference in personal guaranty vs collateral, and secured lines in secured business line of credit.

Pros and cons of a credit union line

Where it can fit well:

You already bank with the credit union and have a clean history there.
You want a local lender who knows your market.
Your need fits inside the credit union’s size limits.
You are comfortable with a full application and a personal guaranty.

Where it can fall short:

You are not eligible to join, or joining takes extra steps.
The credit union is small and can’t offer the limit you need.
You need an answer on a short timeline. Commercial underwriting with full financials can take a while.
Your business is young and the policy wants years of history.

None of this makes a credit union better or worse than a bank or an online lender. It is a different set of trade offs. If you are weighing other options, my bank loan alternatives post and the roundup of business lines of credit lay out the field.

Credit unions and SBA lines

Some credit unions take part in SBA programs. That matters for lines because SBA Express and CAPLines can be revolving. Under 12 CFR 723.4, the portion of a loan backed by a federal or state agency program, such as the SBA share, is left out of the one borrower limit, which can give a smaller credit union more room. I compare Express with standard 7(a) in SBA Express loan vs 7(a) loan.

How to apply at a credit union

Confirm you are eligible to join, and open a membership if needed.
Ask whether they offer business lines and the typical size range.
Gather two to three years of tax returns, recent bank statements, a current profit and loss statement and a balance sheet.
Check your personal credit and fix errors before you apply.
Ask what collateral and guaranties they expect, and what fees apply to open, renew or keep the line.
Ask whether the line renews each year and what happens at renewal.

Guru’s Take

If you already belong to a credit union, start there and ask about a business line before you look elsewhere.

FAQ

Do I have to be a member to get a credit union business line of credit?

Yes. Credit unions lend to members. You join through the credit union’s field of membership, which can be based on your employer, family, a group or where you live or work. Ask about membership first.

Are credit union business lines cheaper than bank lines?

Sometimes, not always. The NCUA says credit unions on average offer lower loan rates, and federal credit unions have a rate ceiling. Your actual price depends on the credit union and your file. Compare total cost, including fees, before you choose.

How large can a credit union business line of credit be?

It depends on the credit union. For credit unions covered by the federal rule, commercial credit to one borrower is generally capped at the greater of 15 percent of the credit union’s net worth or $100,000, with some room above that for certain collateral and for the SBA backed share of a loan. Larger credit unions can go bigger.

Will a credit union require a personal guaranty?

Usually. Federal rules make a full personal guaranty from controlling owners the default, and a credit union must document its reasons if it skips one.

Can a new business get a credit union line of credit?

It can be hard. Many commercial loan policies want a track record, and covered credit unions must ask for a projection when history doesn’t support the payments. See line of credit for startups for other paths.
