What is a business line of credit and how do you qualify?

A business line of credit is revolving credit—you borrow what you need, repay it, and redraw as cash flow allows.

You're approved for a maximum limit, but you pay interest only on the amount you actually draw. Unlike a term loan (a fixed lump sum), a line of credit lets you access capital on demand—ideal for managing payroll gaps, seasonal inventory swings, or unexpected equipment repairs. Repayment is typically interest-only each month, with the balance due in full at maturity (usually 3–5 years). As you pay down the balance, that credit becomes available to redraw.

The specifics

To qualify for a business line of credit, you'll meet these concrete thresholds:

Credit score: According to the SBA 7(a) loan guidelines, 640+ FICO is the standard for traditional bank and SBA-backed lines. Fair-credit borrowers (620–680 FICO) can qualify through online lenders and credit unions, though expect rates 1–2 percentage points higher than prime-tier borrowers.

Time in business: The SBA requires 24+ months of operating history for most institutional lenders. Startups under 2 years are ineligible for traditional bank lines but may access fintech and alternative lenders at significantly higher cost (15–24% APR) and smaller limits.

Revenue and debt service: Most lenders cap your total monthly debt payments at 40% of gross monthly revenue. If you gross $10,000 per month, your maximum monthly debt obligation is $4,000. This threshold protects your business during downturns and ensures the lender has margin for error.

Documentation: Lenders typically review 2–6 months of business bank statements, personal and business tax returns (last 2 years), and a current balance sheet. Online lenders may approve faster with fewer documents but charge higher rates to compensate for the risk.

Business structure: Sole proprietorships, LLCs, S-Corps, and C-Corps all qualify. You'll likely guarantee the line personally, meaning your personal credit score and financial statement back the obligation.

How rates and qualification work in 2026

According to NerdWallet's June 2026 survey on average business loan interest rates, unsecured business lines of credit typically range from 8–18% APR depending on credit quality and lender type. LendingTree's 2026 working capital loan guide reports that secured lines—backed by equipment, inventory, or real estate—cost 1–3 percentage points less than unsecured options.

Traditional banks tend to price prime-credit borrowers (740+ FICO) at 8–12% APR, while online lenders and fintech platforms charge 12–18% for comparable borrowers. The rate spread reflects speed of approval and underwriting flexibility: online lenders approve in days and accept weaker credit profiles; banks take longer but demand stronger credentials.

Qualification edge cases

Fair-credit borrowers (620–680 FICO): You will qualify, but expect to pay 1–2 percentage points above prime rates. Most online lenders and credit unions serve this segment; traditional banks often decline outright. If you're in this range, apply to 2–3 lenders simultaneously (within 14 days) to minimize credit-inquiry damage and compare terms.

Startups under 24 months: Most banks will decline you. Enova's 2026 report on small business access to capital shows alternative lenders sometimes accept businesses with 6–12 months of history, but at significantly higher rates (15–24% APR equivalent) and smaller limits ($5,000–$50,000). Consider building 6 more months of bank statements before applying to mainstream lenders.

Debt-to-income already above 40%: You're overleveraged in most lenders' eyes. Before you apply, calculate your actual debt-to-income ratio using our affordability calculator. If you're genuinely over the threshold, pay down existing debt first or explore alternative funding options like revenue-based financing or invoice factoring.

Recent late payments or charge-offs: You may still qualify but expect 2–4 percentage points higher rates and a lower credit limit (often 50% of what you'd receive with clean payment history). If the late payment is older than 12 months, your approval odds improve significantly.

Background: how business lines of credit work

A business line of credit sits between a credit card and a term loan in cost and flexibility. Credit cards offer unlimited flexibility but charge 18–28% APR—unsustainable for working-capital borrowing. Term loans cost less (8–14% APR) but give you a single lump sum with a fixed repayment schedule. Lines of credit split the difference: you get revolving access at moderate rates (8–18% APR depending on credit), and you pay interest only on what you draw.

Lines work best for managing seasonal cash gaps, float inventory purchases, or covering payroll in slow months. They're less suitable for one-time capital purchases—equipment finance or an SBA 7(a) loan is cheaper for those. Crestmont Capital's 2026 working capital loan trends report shows lines are the fastest-growing working capital product among mid-market businesses, driven by simplicity and speed of access.

Once approved, you'll receive a credit card, checkbook, or online portal linked to the line. Each draw is a separate transaction; interest accrues daily on the outstanding balance. Most lines require monthly interest-only payments, though some allow a 30–60 day grace period on small draws. At maturity, the balance is due in full—this is where cash-flow planning matters. If you can't pay the full amount, you'll either refinance the line or negotiate an extension with your lender.

Bottom line

A business line of credit is flexible, revolving capital you draw and repay as needed. Most lenders require 640+ FICO, 24+ months in business, and monthly debt payments under 40% of revenue. See the rate you qualify for in 2 minutes—no credit-score hit using our affordability calculator.
