A business line of credit gives you access to a set amount of money you can borrow, repay, and borrow again. It works like a financial safety net — the funds are there when you need them, and you only pay interest on what you actually use. For small business owners managing unpredictable cash flow, it can be one of the most flexible financing tools available.
But flexibility also comes with complexity. Understanding how draws work, how repayment is structured, and what lenders want to see in your application will help you use this tool strategically — not just when you’re in a pinch.
Key Takeaways
- You only pay interest on what you draw, not on the full credit limit.
- Most lines of credit are revolving, meaning repaid funds become available again.
- Draw periods and repayment terms vary by lender — knowing the difference protects you from surprises.
- Lenders evaluate revenue, credit score, time in business, and cash flow when deciding whether to approve your application.
- A line of credit works best for short-term, recurring needs. Term loans are better suited for large, one-time purchases.
- Secured lines require collateral; unsecured lines typically need stronger credit and charge higher rates.
What Is a Business Line of Credit and How Does It Work?
Quick Answer: A business line of credit is a revolving loan with a set credit limit. You draw funds as needed, repay what you borrowed, and the available balance resets. You only pay interest on the amount drawn, not the full limit.
Think of it like a credit card for your business, but with a higher limit and usually a lower interest rate. Your lender approves you for a maximum borrowing amount — say, $75,000. You can pull from that pool whenever you need cash, in any amount up to that limit.
Once you repay what you borrowed (plus interest), that amount becomes available again. That’s the “revolving” part. It’s a continuous cycle of access rather than a single disbursement.
Revolving vs. Non-Revolving Lines of Credit
Most business lines of credit are revolving. That means repaid funds cycle back into your available balance. A non-revolving line works more like a term loan — once you draw funds and repay them, the line closes. Non-revolving lines are less common for small businesses but do appear in certain SBA and specialty lending programs.
Secured vs. Unsecured Lines of Credit
A secured line of credit requires collateral — assets like accounts receivable, inventory, or real estate that the lender can claim if you default. An unsecured line requires no collateral but typically demands a stronger credit profile and charges a higher interest rate to offset the lender’s risk.
| Type | Collateral Required | Typical Credit Limit | Interest Rate Range | Approval Difficulty |
|---|---|---|---|---|
| Secured (Asset-Based) | Yes — receivables, inventory, equipment | $50,000 – $500,000+ | 7% – 20% APR | Moderate |
| Unsecured | No | $10,000 – $100,000 | 15% – 40% APR | Higher |
| SBA CAPLines | Depends on program | Up to $5 million | Prime + 3% – 6.5% | High (more documentation) |
| Bank Line of Credit | Often required over $50K | $25,000 – $250,000 | 8% – 18% APR | Moderate to High |
| Online Lender Line | Rarely required | $5,000 – $250,000 | 20% – 60% APR | Lower |
How Do Draw Periods and Repayment Work?
Quick Answer: During the draw period, you borrow funds as needed and make interest-only or minimum payments. After the draw period ends, repayment begins on the outstanding balance. Most draw periods last 6 to 24 months, and repayment terms range from 6 months to 5 years.
The draw period is the window when you can access your credit line. During this time, you request funds — called draws or advances — through online banking, a linked account, or a check. Some lenders require a minimum draw amount, often $500 to $5,000.
Repayment during the draw period usually covers interest only on what you’ve borrowed. Some lenders also require a small principal payment. Once the draw period closes, you enter the repayment period, where you pay down the full outstanding balance — typically in fixed monthly installments.
What Happens If You Miss a Draw Period Deadline?
If you don’t draw any funds by the end of the draw period, the line typically closes or resets. Lenders may require a renewal application to reopen it. Some banks also charge an inactivity fee if you maintain a credit line but never use it — often 0.5% to 1% of the unused balance annually.
How Interest Accrues on a Business Line of Credit
Interest on a business line of credit is calculated daily on the outstanding balance — not on the full credit limit. For example, if you have a $100,000 line but only draw $20,000, you pay interest on $20,000 only. This makes it far cheaper than a term loan if you don’t need the full amount at once.
| Scenario | Credit Limit | Amount Drawn | Interest Rate | Monthly Interest Cost | Draw Period |
|---|---|---|---|---|---|
| Small seasonal draw | $50,000 | $10,000 | 12% APR | ~$100 | 12 months |
| Inventory purchase | $100,000 | $40,000 | 15% APR | ~$500 | 18 months |
| Cash flow gap | $75,000 | $25,000 | 18% APR | ~$375 | 12 months |
| Emergency payroll | $150,000 | $15,000 | 10% APR | ~$125 | 24 months |
When Should a Business Use a Line of Credit?
Quick Answer: Use a business line of credit for short-term, recurring needs — like covering payroll gaps, buying seasonal inventory, or bridging delayed client payments. It’s not the right tool for buying equipment or real estate, where a term loan fits better.
A line of credit shines in situations where your cash needs fluctuate. If you’re waiting 45 days to collect on an invoice but your supplier wants payment in 10, a line of credit bridges that gap cleanly. You borrow what you need, pay back when the invoice clears, and your balance resets.
Common use cases include:
- Seasonal inventory builds — buying product ahead of a busy season
- Payroll coverage — meeting payroll when client payments are delayed
- Emergency repairs — fixing equipment without disrupting operations
- Marketing campaigns — funding a launch before revenue hits
- Accounts receivable gaps — bridging slow-pay clients
When Is a Term Loan a Better Choice?
A term loan delivers a lump sum upfront with a fixed repayment schedule. It’s predictable, often carries a lower interest rate than a line of credit, and is designed for large one-time purchases. If you’re buying equipment, funding a renovation, or acquiring another business, a term loan is the right tool.
| Attribute | Business Line of Credit | Term Loan |
|---|---|---|
| Funding structure | Revolving, draw as needed | Lump sum, one disbursement |
| Interest calculation | On drawn balance only | On full loan balance |
| Repayment flexibility | High — repay and redraw | Fixed monthly payments |
| Best use | Short-term, recurring needs | One-time, large purchases |
| Typical term | 6 months – 2 years (renewable) | 1 – 10 years (fixed) |
| Interest rate | Variable, often higher | Fixed or variable, often lower |
| Collateral | Optional depending on lender | Often required for large amounts |
| Speed of access | Fast after approval | Slower — single underwrite |
What Do Lenders Look for When Approving a Business Line of Credit?
Quick Answer: Lenders evaluate your business credit score, personal credit score, annual revenue, time in business, and monthly cash flow. Most banks want at least 2 years in business, $100,000 or more in annual revenue, and a personal credit score above 650.
Getting approved for a business line of credit requires you to prove two things: that your business generates enough cash to repay what it borrows, and that you’ve managed debt responsibly in the past.
Credit Score Requirements
Your personal credit score matters significantly for small business lending — especially for businesses under five years old. Most traditional banks require a personal FICO score of 680 or higher. Online lenders may approve scores as low as 600, but they charge higher rates to compensate. Your business credit score (from Dun & Bradstreet, Experian Business, or Equifax Business) also factors in once your business has an established credit history.
Revenue and Cash Flow Standards
Lenders look for consistent monthly revenue, not just a single strong month. They want to see that your business generates enough cash to service the debt comfortably. A common benchmark is a debt service coverage ratio (DSCR) of 1.25 or higher. This means your business generates $1.25 for every $1.00 of debt obligation — leaving a buffer.
Time in Business Requirements
Most banks require at least 2 years of operating history before approving a line of credit. Some online lenders will work with businesses as young as 6 months, but the credit limits and rates reflect the added risk. Startups with limited history generally have better luck with SBA-backed programs or CDFI lenders who specialize in early-stage businesses.
| Lender Type | Min. Time in Business | Min. Annual Revenue | Min. Personal Credit Score | Typical Credit Limit | Approval Speed |
|---|---|---|---|---|---|
| Traditional Bank | 2 years | $100,000+ | 680+ | $25,000 – $250,000 | 2 – 4 weeks |
| Credit Union | 1 – 2 years | $75,000+ | 650+ | $10,000 – $100,000 | 1 – 3 weeks |
| Online Lender (e.g., Bluevine, Fundbox) | 6 months – 1 year | $50,000 – $120,000 | 600+ | $5,000 – $250,000 | 1 – 3 business days |
| SBA CAPLines Program | 2+ years | Varies by program | 650+ | Up to $5 million | 30 – 90 days |
| CDFI Lender | 6 months – 1 year | $30,000+ | 550+ | $5,000 – $100,000 | 1 – 2 weeks |
How Do You Apply for a Business Line of Credit?
Quick Answer: To apply, gather 3-6 months of business bank statements, your last 2 years of tax returns, a current profit and loss statement, and your business and personal credit information. Online lenders require fewer documents. Banks typically require a full financial package.
The application process varies by lender type, but the underlying logic is the same — the lender wants to verify your revenue, confirm your creditworthiness, and assess your business’s financial health.
Documents You’ll Typically Need
- Business bank statements — 3 to 6 months, showing consistent cash flow
- Business and personal tax returns — 1 to 2 years
- Profit and loss statement — current year, year-to-date
- Balance sheet — current assets and liabilities
- Business license and formation documents — Articles of Incorporation or LLC operating agreement
- Accounts receivable aging report — if applying for an asset-based line
How Long Does Approval Take?
Online lenders can approve and fund a line of credit in 24 to 72 hours. Traditional banks take 2 to 4 weeks because they manually underwrite the full financial package. SBA CAPLines programs take the longest — often 30 to 90 days — due to the government guarantee process and documentation requirements.
What Are the Fees and Costs of a Business Line of Credit?
Quick Answer: Beyond interest, business lines of credit may include origination fees (1%–3%), annual maintenance fees ($100–$500), draw fees ($5–$50 per draw), and inactivity fees (0.5%–1% of unused balance). Always calculate the total cost — not just the interest rate.
Interest rate alone doesn’t tell the full story. A line with a 12% APR and a $400 annual fee may cost more than one with a 15% APR and no fees — depending on how much you draw and how often.
Common Fee Types to Watch For
- Origination fee: Charged at approval, typically 1% to 3% of the credit limit
- Annual renewal fee: $100 to $500 per year to keep the line open
- Draw fee: $5 to $50 each time you pull funds
- Inactivity fee: 0.5% to 1% annually on unused balance if you never draw
- Prepayment penalty: Rare for lines of credit, but check before signing
How Does a Business Line of Credit Affect Your Credit Score?
Quick Answer: Applying for a line of credit creates a hard inquiry, which can lower your personal credit score by 5–10 points temporarily. Using less than 30% of your available credit limit and making on-time payments will build your business credit profile over time.
Credit utilization — how much of your available credit you’re using — plays a major role in your credit score. Keeping your drawn balance below 30% of your total credit limit signals responsible borrowing and can improve your score over time.
Late payments on a business line of credit may be reported to both personal and business credit bureaus, depending on whether you signed a personal guarantee. Most small business lines of credit under $100,000 require a personal guarantee — meaning the lender can pursue you personally if the business defaults.
Does Having an Open Line Help or Hurt?
An open, unused line of credit with a zero balance can actually improve your credit score by increasing your total available credit. The key is to avoid maxing it out and to make payments on time. Think of an approved, untouched line as a credit score asset — as long as it doesn’t charge inactivity fees.
What Are the Risks of a Business Line of Credit?
Quick Answer: The biggest risks are overborrowing, variable interest rates that rise with market conditions, and treating the line as a substitute for revenue. A line of credit is a bridge, not a budget. Relying on it for operating costs signals a deeper cash flow problem.
A revolving line makes it easy to borrow repeatedly without a clear payoff date. Some business owners fall into a pattern of drawing down the line, making minimum payments, and never fully paying it off — which is exactly how short-term credit becomes long-term debt.
Variable Rate Risk
Most business lines of credit carry variable interest rates tied to the prime rate (the benchmark rate large banks charge their best customers) or SOFR (Secured Overnight Financing Rate, a widely used short-term interest rate benchmark). When the prime rate rises, your borrowing costs rise with it. In a rising-rate environment, budget for your interest costs to increase by 1% to 2% annually.
Personal Guarantee Risk
If you signed a personal guarantee — and most small business owners do — your personal assets are on the line if the business can’t repay. This includes personal savings, vehicles, and in some cases, home equity. Understand this exposure before you draw significant funds.
Frequently Asked Questions
Can a startup get a business line of credit?
Most traditional banks require at least 2 years of operating history. However, CDFI lenders and some online lenders work with businesses as young as 6 months. SBA microloan programs also offer early-stage financing for businesses that don’t yet qualify for conventional credit lines.
Is a business line of credit considered a loan?
It is a form of credit, but it functions differently from a term loan. A term loan disburses a fixed amount upfront with scheduled payments. A line of credit is a flexible, revolving facility — you control when and how much you borrow within the approved limit.
Does a business line of credit require a personal guarantee?
Most lenders require a personal guarantee for small business lines of credit, particularly those under $250,000. This means you are personally liable if the business fails to repay. A few lenders offer non-recourse lines for established businesses with strong financials, but they are the exception.
What is a good credit limit for a small business?
A practical benchmark is 10% to 20% of your annual revenue. If your business generates $500,000 per year, a $50,000 to $100,000 line gives you meaningful coverage without creating excessive debt exposure. Lenders often use a similar formula when setting limits.
How often can you draw from a business line of credit?
Most lenders place no limit on draw frequency during the draw period, as long as you stay within your approved credit limit. Some set minimum draw amounts — typically $500 to $5,000 — to reduce administrative overhead on very small transactions.
What is the difference between a business line of credit and a business credit card?
Both are revolving credit tools, but they work differently. A business credit card charges higher interest rates (often 18% to 28% APR) and is designed for everyday purchases. A business line of credit typically offers lower rates and larger limits, with funds transferred directly to your bank account. Lines of credit are better suited for larger, planned borrowing needs.
