A business line of credit is a revolving facility that lets you draw funds up to an approved limit, pay interest only on what you draw, and reborrow as you repay the principal. Unlike a term loan, which charges interest on the full amount from day one, a line of credit only costs you money on the balance you actually use. If you want to see what a revolving credit option looks like for your business, checking your prequalification takes about two minutes, and the breakdown below covers exactly how these facilities work and when they make sense.
Key Takeaways
A line of credit is revolving: you draw, repay, and draw again, paying interest only on the outstanding balance, not the full limit.
Unsecured lines typically carry APRs around 12% to 22% with limits that rarely exceed $250,000. Secured lines typically run 8% to 14% APR with higher limits in exchange for pledged collateral.
Online lenders can fund a line in as little as one to seven days, while bank lines generally take two to six weeks and SBA CAPLines take 45 to 75 days.
Lines of credit fit recurring or intermittent needs like payroll bridges and seasonal inventory, not one-time, long-term purchases.
What a Business Line of Credit Actually Is
A line of credit works more like a credit card than a loan. The lender approves you for a maximum limit, and you draw against it whenever you need cash, whether that is $2,000 or the full amount, and you only pay interest on the portion you have actually drawn. As you repay what you borrowed, that capacity becomes available again, which is the "revolving" part of a revolving line of credit. This structure makes lines of credit meaningfully cheaper than a term loan for intermittent or recurring needs, since a term loan charges interest on the entire principal from the moment it funds, regardless of how quickly you actually use the money.
Line of Credit vs. Term Loan: The Real Difference
A term loan delivers a lump sum upfront that you repay on a fixed schedule, with interest accruing on the full balance from day one. A line of credit delivers access to capital that sits ready until you need it, and the interest meter only starts running on whatever portion you draw. That distinction matters most when your capital need is unpredictable or recurring rather than a single, known expense.
If you know exactly how much you need and what you are buying with it, a term loan or a product built around that specific purchase is usually the better fit. If your need shows up unevenly throughout the year, covering payroll during a slow month, restocking inventory ahead of a busy season, or bridging the gap between issuing an invoice and getting paid, a line of credit is built for exactly that kind of timing problem. For businesses weighing which structure fits their situation, comparing the different types of business loans side by side is worth doing before committing to either one.
How Lenders Decide Your Credit Limit
Lenders set your limit based primarily on your cash flow and revenue history rather than a single factor. Online lenders typically look at three to six months of business bank statements and weigh deposit consistency heavily, which is why a business with volatile daily balances or frequent overdrafts tends to see a lower limit even if total annual revenue looks strong on paper. Banks apply a more document-heavy process, often requiring two or more years of tax returns, full financial statements, and accounts receivable aging reports before setting a limit, which is part of why bank-issued lines tend to come with higher limits but a much longer approval timeline.
Unsecured lines, meaning no specific collateral is pledged against the facility, typically top out around $250,000 for most small businesses, with APRs commonly in the 12% to 22% range. Secured lines, where you pledge business assets or a specific lien against the facility, generally unlock higher limits and lower pricing, often in the 8% to 14% APR range, in exchange for that added collateral step.
Secured vs. Unsecured Lines of Credit
The core tradeoff between secured and unsecured lines comes down to speed and cost versus collateral risk. An unsecured line skips the collateral step entirely, which means underwriting moves faster, often with decisions in one to three days at online lenders, but you pay for that speed and flexibility with a higher interest rate and a lower ceiling on how much you can borrow.
A secured line adds a collateral step, typically a UCC filing against business assets or a specific pledge, and sometimes a formal valuation of that collateral. That additional underwriting generally takes two to six weeks at a bank, considerably longer than an unsecured online application, but it unlocks a lower APR and a higher available limit because the lender has an asset to fall back on if the line goes unpaid. Businesses that already have significant receivables or inventory sitting on their balance sheet are often good candidates for this structure, and it is worth understanding how asset-based lending works more broadly if you are weighing a secured line against a dedicated asset-based facility.
When a Line of Credit Is the Right Tool
A line of credit shines when your capital need is recurring but unpredictable in timing. Seasonal businesses that need to build inventory months before a peak selling season, service businesses bridging the gap between delivering work and collecting payment, and any business that occasionally needs to smooth out payroll during a slower month are all strong candidates. The revolving structure means you are not paying interest on money sitting unused, which makes a line far more cost-efficient than a lump-sum loan for these kinds of intermittent gaps. If cash flow timing has been a recurring pain point for your business specifically, it is worth reviewing practical ways to avoid cash flow problems alongside setting up a line, since the two solutions work well together rather than as alternatives to each other.
When a Line of Credit Is the Wrong Tool
A line of credit is a poor fit for large, one-time purchases with a long useful life, like a piece of equipment, a vehicle, or a facility buildout. Those purchases are better matched to financing structured around the asset itself, where the loan term lines up with how long the asset will actually be useful to your business. Using a revolving line to fund a large capital purchase often means carrying a big balance for an extended period, which erodes the cost advantage that makes lines attractive for shorter-term needs in the first place. If a line was declined or the terms were not competitive enough for your situation, it does not necessarily mean financing is unavailable. Online and alternative lenders often underwrite differently than a bank, and a decline from one source frequently just means your business falls outside that particular lender's specific criteria rather than being unfundable altogether.
Flexibility Has a Price Tag Too
A business line of credit gives you the flexibility to draw capital exactly when you need it and pay for only what you use, which is genuinely valuable for the uneven, unpredictable cash flow timing that most small businesses deal with at some point. But that flexibility is not free, and it is not automatically the cheapest or fastest option for every situation. Matching the loan structure to the actual shape of your need, recurring versus one-time, predictable versus uneven, is what determines whether a line of credit saves you money or simply adds another monthly obligation to track.
