How to Use a Business Line of Credit: Best Uses, Mistakes and Examples
A business line of credit is a revolving pool of money you draw from, repay and draw from again, paying interest only on what is outstanding. Used well, it is the cheapest way to cover timing gaps between paying for work and getting paid for it. Used badly, it turns into a permanent, expensive balance. This guide covers how draws and repayments actually work, the uses that make sense, the ones that do not, and worked examples with real numbers.
How Does a Business Line of Credit Work?
You are approved for a limit, say $100,000. You draw what you need, when you need it, by transfer to your bank account, usually within one business day. Interest accrues only on the drawn balance. You repay on a schedule (weekly or monthly) or ahead of it, and every dollar repaid becomes available to draw again. Most lines run for 12 to 24 months before renewal; bank lines are often reviewed annually. The right use is short-term and self-liquidating: the money goes out, the thing it paid for brings cash back in, and the draw is repaid within weeks or a few months.
Draws, Repayments and the Revolving Cycle
Three mechanics decide how much a line costs you in practice.
Draws
Most lenders let you draw any amount up to the available limit, with a minimum of $500 to $1,000. Online lenders deposit funds the same or next business day; banks may take two to three days. Some lenders charge a draw fee of 1% to 3% of each advance, which is why many small draws cost more than one larger one.
Repayment
Bank lines usually require interest-only monthly payments with principal due at renewal or on a schedule you choose. Online lines typically set a fixed weekly or monthly payment that amortizes each draw over 6, 12 or 24 months, with no penalty for paying early. Either way, interest stops accruing on whatever you repay.
Revolving availability
Repaid principal becomes available again immediately. A $100,000 line that you draw and repay four times in a year has moved $400,000 through your business while you paid interest on only the outstanding balance each day.
One revolving cycle on a $100,000 line
At 12% APR, holding $40,000 for 45 days costs about $600. The same draw held for a full year would cost $4,800.
The Best Uses for a Business Line of Credit
A line fits any expense that will be paid back by revenue within a few months. The strongest cases:
- Bridging receivables. You invoice on net-30 or net-60 terms but pay payroll every two weeks. Draw to cover payroll, repay when the invoice clears. This is the single most common and most sensible use.
- Seasonal inventory. A retailer stocking for the holidays or a landscaper buying material in March draws in the slow season and repays in the busy one.
- Starting a new contract. Materials, deposits and the first payroll on a job before the first progress payment arrives.
- Taking supplier discounts. A 2% discount for paying in 10 days instead of 30 is worth about 36% annualized; a line at 12% to make that payment is a clear win.
- Emergency repairs and replacements. A compressor fails or a truck needs a transmission; a draw keeps the business running while you arrange longer-term financing if needed.
- Short-term marketing pushes. Funding an ad campaign ahead of a launch when the sales will land within the quarter.
- A safety net. An open, undrawn line costs little or nothing at most banks and gives you a buffer so a slow month does not become a crisis.
When Not to Use a Line of Credit
A line is the wrong tool whenever the money will not come back within the draw’s repayment period. The usual mistakes:
| Poor use | Why it backfires | Better tool |
|---|---|---|
| Buying a $150,000 machine | Paid back over 5–7 years of use; the line wants it back in months | Equipment financing at a fixed rate over the asset’s life |
| Buying out a partner or acquiring a business | Long-term, large, and ties up the whole line | SBA 7(a) or a term loan |
| Covering chronic monthly losses | The balance never comes down; you are borrowing to lose money | Fix pricing or costs first; a line only buys time |
| Paying personal expenses | Breaks the business-purpose covenant and complicates taxes | Owner draw or salary |
| Consolidating MCAs | Most lines are too small and the lender will decline a stacked file | Reverse consolidation or a term loan |
| Real estate down payment | Years to repay; lender may call the line at renewal | Commercial mortgage or a business HELOC |
Worked Examples With Real Numbers
Example 1: Staffing agency bridging payroll
A staffing firm bills $180,000 a month on net-45 terms and runs payroll of $70,000 every two weeks. It carries a $150,000 bank line at 10.5% APR. Each cycle it draws about $120,000 for 45 days and repays from collections. Interest per cycle: roughly $1,550. Annual cost: about $12,500 to support $2.1 million in billings — well under 1% of revenue, and far cheaper than factoring the same invoices.
Example 2: Retailer stocking for Q4
A gift shop draws $60,000 on a $75,000 online line in September at 1.8% per month on the balance plus a 2% draw fee ($1,200). It repays $20,000 a month in November, December and January. Interest: roughly $2,160. Total cost: about $3,360 to fund $60,000 of inventory that sold for $150,000. The draw fee was a third of the cost, which is why a single draw beat three smaller ones.
Example 3: Contractor with an expensive mistake
A contractor uses a $100,000 line at 14% to buy a $90,000 excavator, expecting to repay it from jobs. Eighteen months later $70,000 is still outstanding, the line is maxed and the lender declines renewal because the balance never revolved. Interest paid: about $17,000. An equipment loan at 9% over 60 months would have cost about $6,900 in the same period and left the line open. See equipment loan vs. lease for the right structure.
Cost of three real uses over one year
The right use keeps the cost tiny relative to the revenue it supports; the wrong use is both more expensive and blocks the line for its real purpose.
Habits That Keep the Line Healthy
Lenders review how you use the line at every renewal, and good habits earn higher limits and lower rates.
- Draw with a repayment date in mind. Note the invoice or sales event that will repay each draw; put it on the calendar.
- Rest the line. Banks like to see the balance hit zero at least once a year, sometimes for 30 consecutive days. A line that is always drawn looks like a term loan the lender did not price for.
- Prefer one larger draw over many small ones if your lender charges draw fees; the reverse if it does not.
- Pay early when cash arrives. Interest is daily; there is no benefit to holding cash in checking while a draw accrues at 12% or more.
- Do not stack. Two online lines plus an advance reads as distress to every underwriter and usually violates the first lender’s agreement.
- Keep the limit below what the business can repay in 90 days of normal operations. That is the lender’s own rule of thumb and a good one.
- Send updated financials before renewal. A growing business that documents it gets an increase; see how limits are set.
Line of Credit vs. Term Loan vs. Credit Card
Owners often ask whether a line is better than a loan or a card. It depends on the shape of the need.
| Line of credit | Term loan | Business credit card | |
|---|---|---|---|
| Best for | Recurring short gaps, uncertain timing | One-time, known amount, long payback | Small purchases, points, 0% intro offers |
| Cost basis | Interest on drawn balance only | Interest on full amount from day one | 20–30% APR after intro; 0% if paid monthly |
| Typical size | $10K–$500K (more secured) | $25K–$5M | $5K–$50K |
| Repayment | Revolving; weekly or monthly | Fixed over 1–10 years | Minimum monthly; revolving |
| Rate (2026) | 8–60%+ by lender | 7–30% | 18–30% |
Many businesses hold all three: a card for daily spend, a line for cash-flow gaps and a term or equipment loan for big purchases. Compare current pricing in our guide to business line of credit rates.
How RAN Funding Helps You Use a Line Well
We place lines of credit from bank, SBA, asset-based and online lenders, and we size them to how you will actually use the money rather than to the largest number a lender will approve. If a draw you have in mind is really a term loan or an equipment purchase, we will say so and quote that instead; it is usually cheaper, and it keeps your line open for its real job.

Common Questions
Can I use a business line of credit for anything?
For any legitimate business purpose, yes. Personal use is prohibited by nearly every agreement and can trigger default. Practically, a line works best for short-term needs that revenue will repay within a few months, not for long-lived assets or acquisitions.
How often can I draw on a business line of credit?
As often as you like up to the available limit, subject to minimum draw amounts (often $500 to $1,000) and, at some lenders, a per-draw fee. Repaid principal is available to draw again immediately.
Do I pay interest if I do not use the line?
No interest accrues on an undrawn line. Some lenders charge an annual fee, a monthly maintenance fee or an inactivity fee, so check the agreement; many bank lines and most online lines have no cost when unused.
Should I pay off my line of credit every month?
Pay it down as soon as the cash that the draw was meant to be repaid from arrives. Interest accrues daily, so carrying a balance you could repay costs money for no benefit. Bank lenders also like to see the balance return to zero periodically.
Can I use a line of credit to pay off a merchant cash advance?
Sometimes, if the line is large enough and the lender allows it, but most lenders decline files with multiple active advances. A reverse consolidation or a term loan is usually the practical route, after which a line can be opened on the cleaner file.
What happens at renewal?
The lender reviews updated financials and usage. A well-used line is typically renewed, often with a higher limit; a line that has sat maxed for a year may be converted to a term loan or not renewed. Send current financials and show the balance revolving before the review date.
