Business Line of Credit in 2026: How It Works, What It Costs and How to Qualify

A business line of credit is the financing most owners wish they'd set up before they needed it. It covers the gap between paying suppliers and getting paid by customers, funds seasonal inventory, and keeps payroll on time in a slow month, and you pay interest only on what you use. This guide explains how a line works, secured versus unsecured lines, SBA's CAPLines and Express lines, what lenders look for, what it costs at today's prime rate, and when a term loan or credit card is the better tool. Rates and SBA terms were checked against Federal Reserve and SBA sources in October 2026.

Quick answer

A business line of credit is a revolving credit limit you can draw from, repay and draw again. You pay interest only on the balance you've used. Bank lines are usually variable, priced at prime plus a margin, with prime at 7.00% in early October 2026. SBA-backed lines through CAPLines or SBA Express can help businesses that don't qualify for a conventional line.

• Best for short-term, recurring needs: inventory, receivables, payroll gaps

• Secured lines use collateral (receivables, inventory, cash); unsecured lines usually need strong credit and a personal guarantee

• SBA CAPLines go up to $5 million; SBA Express lines up to $500,000

• SBA caps line rates at prime + 3% to prime + 6.5% depending on size

• Drawing $40,000 and repaying it over four months costs about $1,000 in interest at 10%, versus thousands on a term loan

How a business line of credit works

A lender reviews your business and sets a credit limit, say $100,000. During the draw period you can borrow any amount up to that limit, by transfer, check or card depending on the lender. Interest accrues only on the outstanding balance. When you repay, that amount becomes available again, which is what makes it revolving.

The key terms to understand:

• Draw period: how long you can keep borrowing. Bank lines are often reviewed and renewed every year or two; SBA Express revolving lines can run up to 10 years.
• Repayment: many lines require monthly interest-only payments on the balance, plus periodic paydowns. Some lenders require the balance to drop to zero for a set period each year (a "clean-up" requirement) to show it's used for short-term needs.
• Rate: usually variable, set as an index (commonly the prime rate) plus a margin. When the Federal Reserve moves rates, your cost moves too.
• Fees: some lenders charge an origination fee, annual or maintenance fee, draw fees, or a fee on the unused portion. Ask for every fee in writing and include them when you compare offers.
• Borrowing base: for lines secured by receivables or inventory, the amount you can draw may be tied to a percentage of eligible receivables and inventory, reported monthly.

Lines are a mainstream product. In the Kansas City Fed's survey of banks for the first quarter of 2026, new small business credit lines rose 31.1% year over year, borrowers were using a median of 40.7% of their available lines, and variable-rate lines made up about 91% of credit line usage.

Secured vs unsecured lines

"Unsecured" rarely means no strings. Lenders typically file a UCC-1 financing statement giving them a lien on business assets, and most require a personal guarantee from the owners. If a lender advertises a line with no personal guarantee, read the terms closely; those are usually reserved for larger or fully cash-secured borrowers.

SBA lines of credit: CAPLines, Express and Working Capital Pilot

If a bank likes your business but won't extend a conventional line, SBA's 7(a) program has revolving options where SBA guarantees part of the lender's risk. You apply through an SBA lender, not SBA.

SBA rules apply to all of these: rates can't exceed prime plus Prime + 3.0% for amounts over $350,000, up to prime plus Prime + 6.5% for $50,000 or less; every 20%+ owner gives an unlimited personal guarantee; and lines over $50,000 generally need collateral where it's available, although SBA says a loan shouldn't be declined solely for inadequate collateral. Upfront guaranty fees apply too; see our SBA 7(a) loan guide for the current fee table and eligibility rules, including the October 1, 2026 citizenship requirement.

What does a business line of credit cost?

Rates move with the market, so start with the index. The Federal Reserve's H.15 release showed the bank prime loan rate at 7.00% for the week ending October 5, 2026. Most bank lines are priced as prime plus a margin set by your risk profile, collateral and relationship, and many include a floor rate.

The SBA rows are legal maximums, not quotes; your lender can charge less. Online lenders' pricing can be much higher than bank pricing once fees are annualized, so ask for the APR and total cost in dollars.

Worked example: a seasonal draw, a term loan and a credit card

Rosa runs a garden center with a $100,000 bank line at prime + 3%, which is 10.00% variable at today's prime. Each spring she buys stock before the selling season.

• March 1: she draws $40,000 for plants and supplies. Interest at 10% is about $333 a month, and she makes interest-only payments.
• May 1: she repays $20,000 from spring sales. Two months of interest on $40,000 cost about $667, and $80,000 of credit is available again.
• July 1: she repays the last $20,000 after two more months at about $167 a month ($333).
• Total interest for the season: about $1,000. The line stays open with nothing owed until her next draw, apart from any annual fee in her agreement.

Compare the alternatives for the same need:

Cost of funding Rosa's spring stock

≈ $1,000

Line of credit at 10%

Interest only on what's drawn, for 4 months

$2,125/mo

$100,000 term loan at 10% over 5 years

≈ $27,500 total interest; she pays on money she doesn't need

≈ $2,215

Same draws on a card at 22.15%

If she carried the balance like the line

The line wins because Rosa borrows only for as long as she needs the cash. If her bank's margin were higher, say prime + 6% (13.00%), the season would cost about $1,300, still well below the other options. Model your own figures with the working capital calculator or check term loan payments in the loan payment calculator.

Line of credit vs term loan vs business credit card

A useful rule: match the financing to how long the money is tied up. Cash that comes back within months belongs on a line; assets you'll use for years belong on a term loan.

Requirements: what lenders look for

Each lender sets its own standards, but most applications are judged on:

• Cash flow: bank statements and profit and loss showing you can service the line.
• Time in business and revenue: banks generally prefer an operating history with tax returns.
• Credit: your business credit file and the owners' personal credit.
• Collateral: for secured lines, details of receivables (aging reports), inventory or the asset pledged.
• Personal guarantee: standard for small businesses, and required by SBA from every 20%+ owner.
• Documents: business and personal tax returns (commonly two to three years), year-to-date financial statements, a debt schedule, formation documents and your EIN.

Approval isn't guaranteed. In the Federal Reserve Banks' 2025 Small Business Credit Survey (published 2026), 38% of employer firms applied for a loan, line of credit or merchant cash advance, and 42% of applicants received the full amount they sought. Applicants at small banks were the most likely to be fully approved (57%), while the share applying at online lenders has grown from 17% in the 2020 survey to 29%.

How to get a business line of credit

1. Separate business and personal finances: EIN, business bank account, clean books
2. Pull your personal credit and your business credit file; fix errors first
3. Prepare two to three years of tax returns and year-to-date financials
4. Size the line: estimate your largest cash gap over the year
5. Ask your current bank first, since it already knows your accounts and cash flow
6. Request quotes from at least two other lenders, including an SBA Express or CAPLines lender
7. Compare APR, all fees, renewal terms, clean-up requirements and covenants
8. Read the personal guarantee and lien language before signing

Set it up before you need it. Lenders are more willing to approve a line when your recent statements look healthy, not in the middle of a cash crunch. Need the basics first? See our guide to getting an EIN.

Mistakes to avoid

• Funding long-term assets with a line. If you use the line to buy equipment, it stays maxed out and stops working as a cash buffer.
• Ignoring renewal risk. Banks can reduce or not renew a line at review; keep financials current and talk to your banker early.
• Comparing rates, not costs. A low headline rate with draw and maintenance fees can cost more than a slightly higher rate with none.
• Missing the variable-rate risk. A one-point rise in prime adds about $400 a year on a $40,000 balance.
• Mixing personal spending into the line. It muddies your books and can breach the agreement.

What to do next

Work out the largest cash gap your business faces in a typical year, using the working capital calculator, and size your line around it with some headroom. Then ask your bank for a quote and compare it with an SBA Express or CAPLines lender through Lender Match. If you're weighing other funding, compare the SBA 7(a) loan and whether any small business grants fit your situation.

Frequently asked questions

How does a business line of credit work?

A lender approves a maximum credit limit, and you draw money only when you need it, up to that limit. You pay interest only on the amount you've drawn, not the whole limit. As you repay, the available credit refills, so you can borrow again during the draw period. Most bank lines are variable-rate, priced as a margin over the prime rate, and are reviewed or renewed periodically.

What credit score do you need for a business line of credit?

There's no single legal minimum; each lender sets its own standards. Banks focus on your business's cash flow, financial statements, time in business and your personal credit, because owners usually sign a personal guarantee. SBA doesn't set a minimum credit score for 7(a) lines either. Expect stronger credit and two or more years of history to get the lowest prime-based pricing.

What is the interest rate on a business line of credit?

Bank lines are usually variable and priced as prime plus a margin. The prime rate was 7.00% in early October 2026, per the Federal Reserve. SBA-backed lines are capped at prime plus 3% to prime plus 6.5% depending on size, which works out to 10.00% to 13.50% at that prime rate. Online lenders often quote fees or factor rates instead, so convert everything to an APR to compare.

Can a new business get a line of credit?

It's harder but possible. Start-ups with little revenue history usually need collateral, such as a cash deposit for a secured line, or a strong personal credit profile and a personal guarantee. An SBA Express or CAPLines line through a bank is another route, though SBA lenders still need to see repayment ability. A business credit card is often the easiest first step.

Is a line of credit better than a business loan?

It depends on the use. A line of credit is better for uneven, short-term needs such as seasonal inventory, payroll gaps or waiting on customer payments, because you pay interest only on what you use. A term loan is better for one-time, long-life purchases such as equipment or a building, where a fixed payment over several years matches the asset.

Do business lines of credit require a personal guarantee?

Most small business lines do. Banks and online lenders commonly ask owners to guarantee the debt personally, and SBA requires an unlimited personal guarantee from every owner of 20% or more on its loans, including CAPLines and Express lines. Lines without a guarantee generally go to larger, well-capitalized businesses or are fully secured by cash or investments.
