Business Line of Credit Rates: What They Cost and What Drives Them

A business line of credit is a revolving limit you can draw from, repay, and reuse — and you only pay to carry the balance you actually pull, not the full limit. In 2026, rates run roughly from 8% APR on the strongest bank lines to 50%+ effective cost on fast, revenue-based online lines. The gap comes down to who is underwriting you: banks price low but want two-plus years in business, strong credit, and clean financials; online and marketplace lenders price higher but fund thin files, newer businesses, and FICO scores as low as 500 in 24 to 48 hours. The headline rate is only half the story. What a line really costs depends on how much you draw, how fast you repay, and the draw, origination, and maintenance fees stacked on top. This guide breaks down the ranges, what moves your number, and how the repayment actually hits your bank account week to week.

Typical Business Line of Credit Rate Ranges in 2026

Line of credit pricing splits sharply by who funds it. The tradeoff is consistent across the market: the lowest rates come with the strictest requirements and the slowest funding, while the fastest, most flexible lines cost the most. On the revenue-based and marketplace side — where approval leans on your bank deposits more than your credit score — pricing is often quoted as a factor or fee rather than a clean APR, so you have to translate it back to a true annual cost to compare fairly.

APR is the most useful comparison number because it folds fees into the rate. A line quoted at a low weekly or monthly rate can carry a far higher effective cost once draw and origination fees are counted, so always convert to an annualized figure before comparing offers. For how revenue-based pricing works under the hood, see the revenue-based financing guide.

How Interest Is Actually Charged on a Line of Credit

A line differs from a term loan in one important way: interest accrues only on the outstanding balance, and only for the days you carry it. If you have a $50,000 limit but draw $10,000, you pay to carry $10,000. Repay it, and the cost stops. That makes a line efficient for uneven or recurring expenses — payroll gaps, inventory buys, waiting on invoices — where you cannot predict the exact amount or timing in advance.

Most lenders express the cost as an annual rate but bill it in periodic increments. The table below shows a simplified example of the carry cost on a single draw, before any additional fees.

These figures are illustrative and rounded. The takeaway is simple: carrying a balance longer, or borrowing more, scales the cost proportionally — so a line rewards borrowers who draw deliberately and repay quickly.

How Repayment Hits Your Cash Flow

The headline rate tells you what a draw costs. Your cash flow cares about something different: how the repayment lands on the bank balance, and how often. This is where lines split into two camps.

Bank and SBA lines usually bill monthly — one interest charge, plus any principal you choose to pay down. The hit is predictable and easy to plan around. Revenue-based and marketplace lines, by contrast, often pull repayment daily or weekly, sometimes as a fixed ACH and sometimes as a percentage of deposits. A daily or weekly pull is smoother in size but relentless in timing: it comes out whether or not your customers have paid you yet. If your revenue is lumpy — big deposits some weeks, quiet stretches in between — a daily debit can bite hardest exactly when the account is thin.

Before you draw, map the repayment against your real deposit rhythm, not your average month. Ask two questions: what day does the debit hit, and what is the lowest my balance realistically goes that week? A line you can carry comfortably at average revenue can still cause an overdraft on your slowest week. Match the draw size and repayment frequency to how money actually moves through the account. For the broader mechanics of matching financing to cash flow, see the working capital guide.

Fees That Sit on Top of the Rate

The interest rate rarely tells the whole story. Several fees can raise your effective cost, and they vary widely between lenders. Reading the fee schedule matters as much as reading the rate.

• Draw fee: a flat percentage (often 1%–3%) charged each time you pull funds. Frequent small draws can make this the single largest cost.
• Origination / setup fee: a one-time charge to open the line, sometimes deducted from your first draw.
• Maintenance / monthly fee: a recurring charge to keep the line open, whether or not you draw.
• Annual fee: common on bank lines, sometimes waived above a minimum usage level.
• Late / NSF fees: penalties that can also trigger a rate increase on some agreements.

A line with a modest APR but a per-draw fee can cost more than a higher-APR line with no draw fee, depending on how you use it. Match the fee structure to your usage: infrequent large draws favor low draw fees; a rarely used standby line favors low or no maintenance fees.

What Underwriters Actually Look At

On the revenue-based and marketplace side of the market, underwriting looks less like a credit review and more like a cash-flow review. The score matters, but the bank statements decide the deal. Here is what actually gets checked:

• Bank deposits, first. Underwriters pull three to six months of statements and read the deposit pattern — monthly volume, how many separate deposits, and whether revenue is steady or spiky. Consistent deposits carry more weight than a high credit score.
• Average daily balance and negative days. A history of overdrafts or frequent negative-balance days is the fastest way to a decline or a smaller limit. It signals the account cannot absorb a repayment pull.
• Existing debits and position. They look for other advances or lines already pulling from the account. Heavy existing daily debits (stacking) shrink what you qualify for and raise pricing.
• Time in business and revenue floor. Most marketplace lines want real operating history and roughly $10,000+ in monthly revenue as a starting point.
• Credit as a modifier, not a gate. FICO 500+ opens the door on many online lines; it shapes your rate rather than being pass/fail.

The practical lesson: clean up the bank account before you apply. Avoid overdrafts in the months before you submit, keep deposits landing in the business account, and don't stack new obligations right before applying.

Documents Needed and a Realistic Timeline

A revenue-based or online line asks for far less paperwork than a bank, which is why it funds faster. Have these ready and you remove most of the delay:

• A completed application with business and ownership details
• Three to six months of recent business bank statements
• A voided business check or bank login for funding and repayment setup
• Basic business verification — EIN, formation, and a government ID for the owner
• For larger limits or bank lines: recent tax returns, a P&L, and a debt schedule

Approval and timing depend on your full file, and no line is ever guaranteed. The single biggest cause of delay is incomplete or inconsistent bank statements — send all pages, for all business accounts, so underwriting doesn't stop to ask for more.

Decision Framework: Is a Line of Credit the Right Tool?

A line of credit is a specific instrument, not a default answer. It fits some needs cleanly and fights others.

This works best when:

• Your expenses are recurring or unpredictable — payroll gaps, inventory reorders, waiting on invoices — and you can't name the exact amount in advance.
• You want capacity on standby and are willing to pay only for what you draw, leaving the rest idle at little or no cost.
• Your deposits are steady enough to absorb a weekly or daily repayment without pushing the account negative.
• You draw deliberately and repay fast, so the balance — and the cost — stays short-lived.

Avoid this when:

• You have a single, known, one-time expense — a term loan usually costs less per dollar for that. See the business line of credit overview for how the two compare.
• Your revenue is thin or highly seasonal and a fixed daily debit would hit hardest on your slowest weeks.
• You already have advances pulling daily from the account — adding another debit raises risk of an overdraft spiral, not relief.
• You'd draw the full limit and carry it for months; at that point you're paying line pricing for term-loan behavior.

If a daily-debit line is straining an account that already carries an advance, the goal is to lower the payment — restructure to reduce the daily or weekly pull so the account can breathe. That is different from paying anything off, and no responsible funder promises to eliminate an existing balance.

Common Mistakes to Avoid

Most of the cost damage on a line of credit is self-inflicted and avoidable. The recurring mistakes:

• Comparing on weekly or monthly rate instead of annualized cost. A low periodic rate with a draw fee can beat — or badly lose to — a higher clean APR. Convert everything to an annual figure first.
• Drawing a cushion you won't deploy. Interest and draw fees both scale with usage; pulling extra you plan to sit on is pure cost.
• Ignoring the debit day. Signing a daily-repayment line without checking your slowest week is how a manageable line turns into overdraft fees.
• Stacking. Taking a new line on top of existing daily debits multiplies the drain on the account and drives future pricing up.
• Applying with a messy bank account. Overdrafts in the prior months tell underwriters the account can't carry a repayment — clean it up before you submit.
• Treating a revolving line like a term loan. Maxing it and carrying the full balance for months forfeits the whole advantage of paying only for what you use.

How to Lower Your Effective Rate

Even after approval, you have levers that reduce what a line actually costs:

• Draw only what you need, when you need it. Interest and draw fees both scale with usage, so don't pull a cushion you won't deploy quickly.
• Repay faster. Because cost accrues on the balance, early repayment cuts it directly — and there is rarely a prepayment penalty on a revolving line.
• Consolidate small draws. If your line charges per draw, one larger pull can beat several small ones.
• Requalify as you grow. After a year of on-time use and stronger revenue, ask for a rate review or shop a bank line to replace a higher-cost online line.
• Keep utilization moderate. Running a line near its limit for long stretches can hurt your credit profile and future pricing.

Used this way, a line becomes a flexible, low-idle-cost tool rather than an expensive standing balance. If you're weighing it against a lump-sum revenue-based product, the merchant cash advance guide lays out where each one fits.
