How does a business line of credit work? The bank approves your business for a borrowing limit. You take funds from that limit when you need them and pay interest just on what you take out. As you repay, you can borrow that money again without starting a new application.
That setup is useful for costs that rise and fall through the year, such as a large inventory order or a gap between paying bills and getting paid. This guide shows small business owners how the limit is set, how draws and payments work, what the line costs, and when another option makes more sense.
Key Takeaways
- The bank sets your credit limit after reviewing your business, credit, and financial records.
- You pay interest on the balance you draw, not on the unused part of your limit.
- Each payment lowers the balance and restores that much access to credit.
- Use a line of credit to cover costs that repeat. A single large purchase is often a better match for a loan with a fixed term.
A Business Line of Credit in Plain Terms
A business line of credit gives your business a set amount it can borrow, repay, and borrow again. You pay interest only on what you borrow. It works much like a business credit card, but a line of credit provides cash in your business checking account.
A traditional business loan is different. You receive the full amount at once and repay it on a fixed schedule.
In the Federal Reserve’s 2026 Report on Employer Firms, meeting operating expenses was the most common reason small firms sought financing, at 56 percent. A small business line of credit can help cover those business expenses. 1st National Bank offers business lines of credit to companies across its six-county market.
How Does a Business Line of Credit Work Once It’s Open?
A revolving line of credit follows a cycle. The bank sets a limit, you draw funds, your payments reopen credit, and the line reaches the end of its term.
The Credit Limit Comes First
Your credit limit is the most you can owe on the line at one time. To qualify for a business line of credit, your business goes through a review first. At 1st National Bank, the business line of credit requirements may include the following.
- Credit history: The bank looks at your business credit score and may check your personal score as well.
- A business bank account: A place for the funds you draw and the payments you make.
- Financial documents: Tax returns and other records that show how your business is doing.
- Business assets: Details about your assets, if they apply to your request.
Your time in business and your revenue are part of the review, too. Underwriting is done in-house, and credit decisions are made locally. Before you apply for a business line, read getting ready to borrow.
Taking a Draw When Your Business Needs Cash
A draw is the amount you draw out of your line. Usually, the money is deposited into your business checking account. Your bank can explain how draws on your line operate.
Say a store pulls a quarter of its limit in March to purchase spring merchandise. Its available credit is reduced by that amount. Interest the store pays is just on the amount it pulls. The other 3 quarters of the credit line do not accrue interest until the business draws down on them.
Can you get cash from a line of credit? In most cases, yes. Once the draw reaches your checking account, you can use it like other business funds.
Repaying the Balance Frees Up Credit Again
Each payment reduces your balance and reopens the same amount of available credit. That is what makes it revolving credit.
At 1st National Bank, repayment terms are set to fit your business, and payments are typically monthly. Your agreement explains how each payment is applied.
A balance that never goes down is a sign the need may be long term rather than short term. Paying on time with a line of credit may help build your business credit.
What Happens When the Line’s Term Ends
Most lines of credit have a set term. Terms for business lines of credit may vary, so check your agreement.
The bank may look at how you’ve used the line and how your business is doing before the term is over. The line may be renewed, the limit may be changed, or the balance may need to be paid back, depending on the review and your agreement.
What happens when the term of a line of credit runs out? Before you sign, read the part of your deal that has the answer. Questions? Contact the commercial lending team.
The Real Cost of a Business Line of Credit
The cost of a business line of credit is determined by your interest rate, any fees included in your agreement, and the length of time you keep the balance.
You only pay interest on the amount you draw from a business line of credit, so timing is important. A short-term draw costs less in interest than a long-term draw.
Line of credit interest rates and costs vary from one lender to the next. Before you sign, ask your banker the following questions.
- Rate: How is the rate set, and can it move during the term?
- Fees: Are there any fees to open, keep, or use the line?
- Payments: How is each monthly payment calculated?
The answers show you the total cost of a business line of credit, not just the rate.
Credit extended mainly for a business purpose is exempt from Regulation Z, the federal Truth in Lending rule, under 12 CFR 1026.3. You aren’t guaranteed the standard consumer disclosures. Read the agreement before you sign.
Secured vs. Unsecured Business Lines of Credit
A secured line of credit is backed by business assets, also called collateral. An unsecured line of credit is approved without pledging specific assets. These two types of business lines suit different situations.
| Feature | Secured line | Unsecured line |
| What backs it | Business assets such as equipment, inventory, or receivables | Your credit profile and the strength of your business |
| What the lender reviews | Your credit, your finances, and the pledged assets | Your credit and your finances |
| Good question to ask | Which assets can be used as collateral? | Is a personal guarantee required? |
Collateral and personal guarantees are both common. Among small firms with debt, the Fed’s 2026 report found that 59 percent used a personal guarantee and 51 percent used business assets. Ask your lender which setup applies to your request.
Line of Credit, Term Loan, or Business Credit Card?
A business line of credit offers a reusable source of funds for costs that repeat. A small business loan with a fixed term is built for a single planned purchase. A business credit card works well for smaller day-to-day purchases.
| Feature | Business line of credit | Term loan | Business credit card |
| How you get funds | Draw as needed, up to your limit | One full amount at the start | Card purchases, up to your limit |
| How interest applies | Only on the amount drawn | On the full amount borrowed | Based on the card’s terms |
| Typical use | Payroll, inventory, supplier bills | Machinery or a commercial property | Travel, supplies, small recurring costs |
Should you get a business loan or a line of credit? A line of credit is right when your costs come and go, and you expect to borrow more than once. For a single equipment purchase, equipment financing is usually a closer match.
The benefits of a business line of credit are quick access to funds and interest charged only on what you use. The cons of a business line of credit depend on your agreement. A variable rate can rise, and a limit can be lowered after a review.

Frequently Asked Questions
When does a business line of credit make sense?
When your company has intermittent expenses, such as supplier invoices that are due before customers pay, it may make sense to get a business line of credit. Additionally, you must have a clear plan for paying back each draw. A term loan can be more appropriate for a long-term necessity.
Do you pay interest on the unused part of the line?
No. Interest applies only to the amount you have drawn, as set out in your agreement. Fee terms are also set in the agreement. Ask your lender whether any fees apply to keeping the line open.
Does a business line of credit affect your personal credit?
It can. The bank may look at personal and business credit scores when you apply. If you sign a personal guarantee, you become personally responsible for the debt if the business can’t repay it. Ask your lender what your request requires.
Can you pay off a line of credit early?
In many cases, yes. Paying down a draw sooner reduces the interest you owe, because interest applies to the balance you carry. Review your agreement for any terms about early payment, and confirm them with your lender.
Do you need a business checking account?
A business bank account may be on 1st National Bank’s list of requirements for a line of credit. It gives you a place to manage the funds you draw. Ask your commercial lender about a 1st National Bank business checking account.
What documents should you bring when you apply?
Bring your business tax returns and, if requested, your personal tax returns. Recent financial statements, your cash flow history, and details on any business assets help too. Your lender will tell you if your request needs anything else.
