If your business has ever had money on the way but bills due today, you already understand why lines of credit exist. Revenue rarely arrives on the same schedule as rent, payroll, and suppliers. A business line of credit is the standard tool for closing that timing gap: a pre-approved pool of money you can dip into when you need it and repay as cash comes in.
This page explains how business lines of credit actually work — the mechanics, the real costs (including the fees that don't show up in the advertised rate), who tends to qualify, and when a line is the wrong tool. By the end, you should be able to look at any line-of-credit offer and know exactly what questions to ask.
What is a business line of credit?
A business line of credit is a set amount of money — the credit limit — that a lender agrees to let your business borrow against, repeatedly, for as long as the line stays open. You don't receive the money up front. Instead, you draw funds when you need them, in whatever amounts you need, up to the limit.
Two features define it:
- You pay interest only on what you draw. If you have a $100,000 limit and draw $20,000, interest accrues on $20,000 — not $100,000.
- It revolves. As you repay a draw, that amount becomes available to borrow again without a new application.
Think of it as the business equivalent of a credit card's structure, but typically with higher limits, lower rates, and cash you can actually use for payroll, suppliers, and rent.
Lines come in two broad flavors. A secured line is backed by collateral — often accounts receivable, inventory, or a blanket lien on business assets — and generally offers better pricing or higher limits. An unsecured line doesn't pledge specific collateral, but nearly all lenders will still require a personal guarantee, meaning you promise to repay personally if the business can't. (Read our full guide to personal guarantees before signing anything.)
How a business line of credit works
Here's the lifecycle from application to repayment:
- Approval sets your limit and terms. Based on your revenue, time in business, and credit profile, the lender approves a limit (say, $50,000), a rate structure, and a repayment schedule for draws.
- You draw when needed. Most providers let you transfer funds to your business bank account online, often arriving the same or next business day.
- Each draw starts its own repayment clock. Many online lines convert each draw into a short amortizing schedule — for example, equal weekly payments over 6, 12, or 18 months. Bank lines more often bill monthly interest with flexible principal repayment.
- Repaid principal becomes available again. Pay down $10,000 and your available credit rises by $10,000.
- The line renews — or doesn't. Lines typically have a review or renewal date. Lenders can reduce the limit, change pricing, or decline to renew, especially if your revenue has weakened.
A worked example
Say you run a landscaping company and draw $25,000 in March to buy materials for spring contracts, at a 14% APR, repaying over 12 months in equal monthly payments.
- Monthly payment: 25,000 × (0.14 ÷ 12) ÷ (1 − (1 + 0.14 ÷ 12)^−12) ≈ $2,244
- Total repaid: about $26,933
- Total interest: about $1,933
If the line also charges a 1.5% draw fee, add $375, bringing the true cost of that draw to roughly $2,308 — about 19% more than the interest alone. That's why you should always price a line by its total cost of a realistic draw, not the headline rate. Run your own numbers in the calculator below.
Good uses — and bad ones
A line of credit is a cash-flow tool. It shines when the money comes back quickly:
- Bridging receivables. You've invoiced $60,000 due in 45 days; payroll is Friday.
- Seasonal inventory. Buying holiday stock in September that sells through December.
- Smoothing predictable dips. A restaurant covering January's slow weeks with February's rebound in sight. (See how this plays out in restaurant financing.)
- Genuine surprises. The walk-in freezer dies; the repair can't wait.
It is usually the wrong tool when:
- The purchase is large and long-lived. Equipment that earns for seven years shouldn't be financed on a 12-month revolving line — that's what equipment financing or a term loan is for.
- You're funding ongoing losses. If the business loses money every month, a line doesn't fix that; it delays the reckoning and adds interest. The line gets drawn to the top and stays there.
- You can't name the repayment source. Before every draw, you should be able to say what specific incoming cash repays it. "Sales will probably pick up" is not a repayment source.
What lenders typically look for
Every provider weighs things differently, but the same factors come up everywhere:
| Factor | Why it matters for a line of credit |
|---|---|
| Monthly revenue | The line is repaid from cash flow, so lenders want steady deposits — they'll read your bank statements closely |
| Time in business | More history means more evidence your cash flow is real; many online providers want 6–12 months minimum, banks often 2+ years |
| Personal credit | Especially for smaller businesses, the owner's score is a proxy for how the business will pay |
| Business credit | An established business credit file expands options and can reduce reliance on your personal profile (how to build it) |
| Existing debt | Lenders check whether current obligations already eat your cash flow — a low DSCR is a common decline reason |
| Industry | Volatile or restricted industries may see lower limits or fewer willing providers |
Lenders verify revenue rather than take your word for it — usually through bank statements or read-only account connections. Our guide on how lenders verify revenue explains exactly what they look at.
Costs and repayment structures
The advertised number is only the start. Price a line on all of these:
- Interest rate. Often variable (a base rate plus a margin), so your cost can rise with the market. Some online products quote weekly or monthly fee rates instead of APR — always convert to APR to compare. Our APR vs. interest rate guide shows how.
- Draw fees. A percentage (commonly 1–3%) charged every time you take money. Frequent small draws can make this the biggest cost on the line.
- Maintenance or inactivity fees. Monthly or annual charges just to keep the line open, whether or not you use it.
- Payment frequency. Weekly (and occasionally daily) payments are common with online providers. The same APR with weekly payments strains cash flow more than monthly — model it before you commit.
- Renewal repricing. The rate that got you in the door can change at renewal. Ask how renewals work and what triggers repricing.
Documents you'll typically need
Requirements scale with the size of the line and the type of lender. A typical checklist:
- Government-issued ID and basic ownership information
- Business bank statements (usually the last 3–6 months) or a read-only bank connection
- Business tax returns, and often personal returns for larger lines
- Basic financials — profit & loss and balance sheet — especially at banks
- Details of existing business debt
- Your EIN and formation documents
Getting these organized before you apply speeds everything up. The full rundown is in our documents guide.
Advantages and disadvantages
Every financing product is a trade. Here is the honest ledger for lines of credit:
Advantages
- You pay interest only on what you actually draw — an unused line costs little or nothing beyond any maintenance fee
- Credit becomes available again as you repay, so one approval covers many needs
- Faster to use in a pinch than applying for a new loan each time
- Regular, well-managed use can strengthen your business credit profile
Disadvantages
- Limits are usually smaller than what the same business could get as a term loan
- Rates are often variable and can rise with the market
- Draw fees, maintenance fees, and inactivity fees can add real cost beyond the quoted rate
- Lenders can reduce or freeze your limit if your revenue weakens — often exactly when you need it most
- Easy access makes it tempting to fund losses instead of fixing them
The last disadvantage deserves emphasis because it surprises people: your limit is not guaranteed. Most agreements let the lender reduce or freeze the line based on your financial condition. Businesses that treat an unused line as their entire emergency plan can find the safety net smaller precisely when revenue drops. A line is a strong first layer of resilience — it shouldn't be the only one.
How to apply, step by step
- Decide the job the line is for. Bridging receivables? Seasonal inventory? Write it down — it determines the limit you actually need.
- Check your numbers first. Know your average monthly revenue, your current debt payments, and your DSCR before a lender calculates them for you.
- Gather documents (list above) so you can complete any application in one sitting.
- Compare at least three providers. Include your existing bank — relationship pricing is real — plus at least one online provider for speed comparison. Use our offer-comparison guide to line them up.
- Convert every quote to total cost. Model a realistic draw (not the full limit) with each provider's rate and fees in the line of credit calculator.
- Read the agreement for the four fine-print questions in the callout above, then sign only when the answers are in writing.
- After opening, do a small test draw and repay it. You'll confirm the mechanics, timing, and fees while nothing is at stake — and start building history with the lender.
Alternatives to consider
- Term loans — better for large, one-time investments where you need the full amount immediately and want a fixed payment.
- Business credit cards — fine for small everyday spending and building credit; expensive if you carry a balance.
- Invoice financing — if slow-paying B2B invoices are the specific cash-flow problem, financing the invoices themselves may fit better.
- SBA lines and loans — SBA programs include lines of credit with rate caps set by program rules; slower to obtain but often cheaper for those who qualify.
- Working capital products — a broader category of short-term options; compare carefully, as some carry much higher effective costs.
How do these stack up side by side?
| Line of credit | Term loan | Business credit card | Invoice financing | |
|---|---|---|---|---|
| Best for | Recurring cash-flow gaps | One-time large investments | Small everyday purchases | Slow-paying B2B invoices |
| Interest charged on | Amount drawn | Full amount from day one | Carried balance | Advanced amount |
| Reusable? | Yes — revolving | No — reapply for more | Yes — revolving | Per invoice |
| Typical cost level | Moderate; varies widely | Often lowest for strong profiles | High if you carry a balance | Fee-based; annualize to compare |
| Funding speed | Draws are near-instant once open | Days to weeks to fund | Instant once open | Often 1–3 days per invoice |
| Main risk | Limit cut when revenue dips | Paying interest on money you don't use | High APR compounds fast | Customer nonpayment (recourse) |

How this is calculated
Interest accrues only on the drawn balance. Repaying a draw with equal monthly payments over n months: M = D × r ÷ (1 − (1 + r)^−n), where D = amount drawn and r = APR ÷ 12. Total cost = interest + draw fees.
- Models a single draw repaid in equal monthly payments — a common way to compare costs.
- Many lines require minimum payments or use weekly schedules; check your agreement's payment schedule.
- Some lines charge maintenance or inactivity fees not modeled here — ask for the full fee schedule.

Frequently asked questions
What's the difference between a business line of credit and a business loan?
A term loan gives you the full amount up front and you pay interest on all of it from day one. A line of credit gives you a limit you can draw against repeatedly, and interest is charged only on what you've drawn. Loans fit one-time investments; lines fit recurring or unpredictable needs.
Does opening a business line of credit hurt my credit?
Applying may involve a hard inquiry on your personal credit, which can cause a small, temporary dip. After opening, on-time payments generally help your business credit profile, while heavy utilization or missed payments hurt it. Ask each lender whether they do a hard or soft pull before you apply.
Can a startup get a business line of credit?
It's harder. Most providers want to see revenue history — often six months to two years — because the line is repaid from cash flow. Newer businesses are usually offered smaller limits, secured options, or are directed to startup-focused products first. See our startup business loans page for paths that fit younger companies.
What credit score do I need for a business line of credit?
There's no universal number. Online providers often consider scores in the low-to-mid 600s, while banks typically want higher. Lenders also weigh revenue, time in business, and cash-flow consistency — a strong business can sometimes offset a mediocre score. Beware of anyone promising approval regardless of credit.
Secured vs. unsecured line of credit — which should I choose?
A secured line is backed by collateral (like inventory, receivables, or a blanket lien) and usually offers a higher limit or lower rate. An unsecured line doesn't require specific collateral but often costs more and almost always still requires a personal guarantee. The honest question is which one you can qualify for at an acceptable total cost.
What happens if I only make minimum payments on my line of credit?
You'll stay current, but interest keeps accruing on the outstanding balance, so the debt shrinks slowly and the total cost grows. Lines work best when draws are repaid on a schedule you set deliberately — use our calculator to see what different repayment speeds cost.
