Business Line of Credit Guide: How They Work, Rates & Best Options (2026)

A business line of credit is a revolving credit facility that lets a business draw funds up to an approved limit, pay interest only on what's actually drawn, and re-borrow as principal is repaid. It works like a business credit card in concept but at meaningfully lower rates (8–22% APR vs 18–28% on most cards) and with cash-out access rather than card-only spending.

The structural advantage over a term loan: a line of credit charges interest only on the outstanding balance, not the approved limit. A $250K line that sits at $0 for six months costs nothing in interest (some lenders charge a small maintenance fee, but no interest accrual). The same $250K drawn as a term loan would have been accruing interest from day one. For businesses with unpredictable or recurring cash needs, that flexibility is the entire reason the product exists.

The trade vs a term loan: lines of credit carry higher headline rates than equivalent-tier term loans (8–22% vs 6–12% on bank term debt), shorter renewal cycles (usually annual review), and they typically require periodic paydown to zero or a personal guarantee. For one-time, planned capital needs (equipment, real estate, business acquisition), a term loan is usually the better instrument. For ongoing working capital, payroll bridges, seasonal swings, and short inventory cycles, the line wins.

The mechanics are straightforward once you've been approved. The lender approves a credit limit (the "line") based on your business's financial profile. You draw funds as needed via online banking, mobile app, or wire request. Interest accrues only on the drawn balance, calculated daily. You repay principal on your own schedule (some products require monthly minimum payments, similar to a credit card; others give full flexibility). As you repay, the credit becomes available again — hence "revolving."

Secured vs Unsecured Business Lines of Credit

The first major fork is collateralization. Secured lines are backed by business assets (accounts receivable, inventory, equipment) or in some cases real estate. They carry lower rates (typically 8–14% APR), higher limits ($250K to $5M+), and stricter underwriting. Unsecured lines have no collateral pledge beyond a personal guarantee — they price higher (12–22% APR), cap lower ($25K–$250K typical), and approve faster. For most small businesses under $1M in revenue, unsecured online lines are the realistic option; secured lines tend to require multi-year operating history and bank relationships.

Draw Structure and Repayment

Most modern business lines of credit settle into one of two repayment patterns:

• Revolver with monthly minimums: You pay a minimum monthly amount (interest plus a small principal) plus whatever extra principal you choose. Balance can sit indefinitely as long as minimums are met. Bank lines and most online lines (Bluevine, Fundbox, OnDeck) work this way.
• Fixed amortization per draw: Each draw locks into a fixed repayment schedule (weekly or monthly, 6–24 months). New draws stack with separate schedules. Some online lenders (Headway, Kabbage-style products) use this structure.

The revolver structure is meaningfully more flexible — if revenue tightens, you can pay the minimum and ride out the cash crunch. The fixed-amortization structure costs less in interest (each draw amortizes down) but creates payment stacking risk if you draw frequently.

Renewal and Annual Review

Business lines of credit almost universally carry an annual review. The lender re-evaluates your revenue, deposits, and credit at renewal and may raise, lower, or freeze the line. Strong performance typically expands the line; declining revenue or NSFs can trigger a reduction or non-renewal. The implicit message: a line of credit is a relationship product, not a one-shot transaction. Lenders watch how you actually use it.

Business line of credit rates run 8–22% APR across the 2026 market, with the spread reflecting credit tier, time in business, and bank vs online structure. Here's the practical breakdown:

Lender category	2026 rate range	Typical limit	Best for
Bank secured line (asset-backed)	8–11% APR	$250K–$5M+	Established businesses, strong banking relationship, real collateral
Bank unsecured line	10–14% APR	$50K–$500K	2+ years, FICO 720+, $500K+ revenue
SBA CAPLine (7(a) line variant)	10–13% APR	$25K–$5M	Working capital, contract financing, builders, seasonal businesses
Online unsecured line (top tier)	12–18% APR	$25K–$250K	1+ year, FICO 680+, $100K+ revenue
Online line (subprime/fast)	18–22% APR	$10K–$100K	6+ months, FICO 600+, $50K+ revenue

Fees Beyond the Interest Rate

Three fees commonly layer on top of the headline APR:

• Origination / opening fee: 0–3% of the line limit, charged once at opening. Banks often waive this; online lenders typically charge 1.5–3%.
• Maintenance fee: $0–$500/month, regardless of whether you draw. Worth modeling against expected utilization — a $250/month fee on a $50K line you barely use is effectively a 6% annual cost on capacity you're paying for either way.
• Draw fee: 0–3% per draw on some online lines. Stacks up quickly if you draw frequently.

The Effective Cost Math

The headline APR on a line of credit is misleading because interest accrues only on what's outstanding. A $100K line at 14% APR used at 30% average utilization costs you roughly $4,200/year in interest, not $14,000. That makes lines of credit meaningfully cheaper than equivalent-rate term loans for use cases where utilization is intermittent.

The flip side: if you actually utilize the line at 80–90% all year, you're paying near-full APR on the balance, and a term loan at a lower headline rate might have been the cheaper instrument. The decision rule of thumb: under 50% expected utilization → line of credit; over 70% sustained utilization → consider a working capital term loan instead.

Eligibility tightens as rate drops — banks demand the most, online lenders the least. Here's what each category actually requires:

Bank Line of Credit Requirements (2026)

• Time in business: 2+ years, ideally 3+
• Annual revenue: $250K+ minimum, $500K+ for unsecured
• Personal FICO: 700+ (720+ for best rates)
• Business credit: Established Dun & Bradstreet profile, Paydex 70+
• Documentation: 2 years business tax returns, 2 years personal tax returns, current YTD P&L and balance sheet, business debt schedule, A/R aging
• Banking relationship: Existing depository relationship typical (not strictly required, but it accelerates approval)
• Personal guarantee: Required from all 20%+ owners

SBA CAPLine Requirements (2026)

The SBA's CAPLine program runs through SBA 7(a) lenders and offers four variants: Working Capital, Contract, Builders, and Seasonal. Requirements largely match SBA 7(a):

• Time in business: 2+ years
• FICO: 680+
• Revenue: $150K+ annual
• SBA eligibility: Owner residency, no federal debt delinquency, SBA-eligible structure
• Documentation: Full SBA package (see our SBA loan requirements guide)

Online Line of Credit Requirements (2026)

• Time in business: 6 months to 1 year, depending on lender
• Annual revenue: $50K–$100K+ minimum
• Personal FICO: 600+ (top tier 680+)
• Bank statements: 3–6 months of business bank statements (Plaid integration common)
• NSF / negative days: Fewer than 3–5 NSFs in the last 90 days
• Personal guarantee: Required

The single biggest disqualifier for online lines is bank account instability — frequent NSFs, low average daily balance, or inconsistent deposit patterns will trigger an automated decline regardless of revenue. Cleaning up your business banking for 60–90 days before applying typically unlocks 1–3 tiers of rate.

The three most common working capital instruments — line of credit, term loan, and revenue-based advance — solve different versions of the same problem. Picking the right structure matters more than picking the right lender within a structure.

	Line of credit	Term loan	Revenue-based advance
Best for	Recurring, unpredictable needs	One-time, planned capital	Fast, flexible, weak qualification
Cost basis	Interest on drawn balance only	Interest on full principal	Factor on funded amount
Approval timeline	15–45 days (bank), 1–7 days (online)	30–90 days (bank), 1–5 days (online)	4–24 hours
Repayment	Flexible draws and paydowns	Fixed monthly amortization	Daily or weekly debits tied to revenue
Renewal	Annual review	Pays down to zero, then refinance	One-time, must reapply for next
Effective cost (recurring use)	Lower	Higher	Highest

When a Line Wins

The line is the right choice when capital needs are ongoing rather than one-shot. Examples: monthly payroll bridges, seasonal inventory builds, accounts receivable timing gaps, opportunistic small purchases that come and go. The pay-interest-only-on-balance structure makes the line cheaper than a term loan over a year of intermittent use, even at a higher headline APR.

When a Term Loan Wins

The term loan wins for one-time, sized, planned capital needs — equipment, real estate, business acquisition, debt consolidation, a single large inventory buy. The lower headline rate compounds in your favor when the full principal is funded immediately and amortized down predictably.

When a Revenue-Based Advance Wins

The revenue-based advance wins when speed or qualification dominates everything else. Funding in 4–24 hours, qualification down to 500 FICO, 6 months in business, $15K+/month revenue. The cost is meaningfully higher than line or term, but it's the only product that solves a 48-hour cash gap for a business that doesn't qualify for traditional credit.

For most small businesses that have time to plan and meet basic qualification thresholds, a line of credit + a term loan together — using the line for ongoing needs and the term loan for one-time capital — is the cheapest realistic structure. A revenue-based advance is a fallback when one of those structures isn't available in the timeline you need.

The application process differs meaningfully by lender category. The mechanics:

Bank Line of Credit Application

Bank lines require a full underwriting package: 2 years business and personal tax returns, current YTD P&L and balance sheet, A/R and A/P aging, business debt schedule, and personal financial statements from all 20%+ owners. The lender reviews the file, requests follow-up, and routes it through credit committee. Timeline: 15–45 days. Best practice is to apply through an existing banking relationship — your business banker can pre-qualify you and shape the application before it goes to underwriting.

Online Line of Credit Application

Online lines are bank-statement based: you connect your business operating account (via Plaid or by uploading 3–6 months of PDF statements), provide a voided business check, business identification, and personal guarantor information. Automated underwriting evaluates deposit consistency, average daily balance, NSF history, and personal credit. Approval and pricing typically returns in hours to 1–2 business days. Funding hits the operating account 1–5 days after approval.

SBA CAPLine Application

SBA CAPLine applications run through the SBA 7(a) process, with all the same documentation requirements (full SBA package, see our SBA loan requirements guide). Timeline: 45–75 days. Worth the effort when the borrower can't qualify for an equivalently-priced bank line and the rate difference vs an online line is meaningful (3–8 percentage points).

Apply Once, Compare Many

For most small businesses, the cleanest path is a brokered application that goes to 50+ lenders simultaneously — both bank and online, secured and unsecured — without triggering multiple credit pulls. You see only the products you actually qualify for, with real pricing, in one application. Explore business line of credit options →
