How a Business Line of Credit Works: A Complete Guide
If you run a small business, you already know that cash needs rarely show up on a predictable schedule. A slow month, an unexpected equipment repair, or a large inventory order can all create pressure on your cash flow. That is exactly where understanding how a business line of credit works becomes valuable. A business line of credit is a revolving financing tool that gives you access to a set pool of funds you can draw from when you need them, repay, and draw from again. Instead of receiving a single lump sum, you get ongoing access to capital on your own terms.
This guide walks through every aspect of how this financing product works, from the draw period and interest calculations to qualification requirements and practical use cases.
What Is a Business Line of Credit?
A business line of credit is a flexible financing arrangement where a lender approves you for a maximum credit limit. You can borrow any amount up to that limit, repay what you have borrowed, and then borrow again without reapplying.
The simplest way to understand it: think of it like a business credit card, but typically with lower interest rates and the ability to transfer funds directly to your bank account.
The key difference between a line of credit and a traditional term loan is structure. With a term loan, you receive a lump sum upfront and repay it over a fixed schedule. With a line of credit, you only borrow what you need, when you need it. That means you are not paying interest on money sitting in your account unused.

How the Draw Period Works
The draw period is the window of time during which you can access funds from your line of credit. During this phase, you can withdraw money up to your approved limit, and you only pay interest on the amount you have actually drawn.
Here is what happens during a typical draw period on a line of credit:
- You request funds. You can draw the full limit or just a portion. Most lenders let you request draws online or through a mobile app.
- Interest accrues on the drawn amount. If your credit limit is $100,000 and you draw $30,000, you pay interest on $30,000 only.
- Your available credit replenishes as you repay. Pay back that $30,000, and your full $100,000 is available again (on a revolving line).
Draw periods vary by lender and product. Some lines of credit have draw periods of 12 to 24 months, while others remain open indefinitely as long as the account stays in good standing. SBA lines of credit, for example, may have draw periods of up to 10 years.
Understanding the draw period on a line of credit is important because once it ends, you typically enter a repayment-only phase where you can no longer access additional funds.
Revolving vs. Non-Revolving Lines of Credit
Not all lines of credit work the same way. The distinction between revolving and non-revolving is worth understanding before you apply.
A revolving line of credit works like a credit card. As you repay borrowed funds, your available credit is restored. You can borrow, repay, and borrow again throughout the draw period. Most business lines of credit are revolving, which is a major part of their appeal.
A non-revolving line of credit gives you access to a set amount, but once you draw and repay funds, that portion of your credit is no longer available. It is a one-time access pool. Non-revolving lines are less common for business financing but do exist.
For most small business owners, a revolving line of credit offers the flexibility that makes this product worth pursuing. The ability to reuse your credit as needs change throughout the year is the core advantage.
How Interest and Fees Are Calculated
One of the most common questions about business lines of credit is how interest works. The short answer: you pay interest only on the amount you have drawn, not on your total credit limit.
For example, if you have a $75,000 line of credit and draw $20,000, interest accrues on $20,000. The remaining $55,000 in available credit costs you nothing until you use it.
Interest rates on business lines of credit vary based on multiple factors, including the lender, your creditworthiness, time in business, revenue, and whether the line is secured or unsecured. Rates can be fixed or variable depending on the product.
Beyond interest, watch for these common fees:
- Draw fees: Some lenders charge a small percentage each time you withdraw funds.
- Annual or maintenance fees: A flat fee charged yearly to keep the line open, regardless of whether you use it.
- Inactivity fees: Charged if you do not use the line for an extended period.
- Origination fees: A one-time fee when the line is first established.
Always review the full fee structure before committing to a line of credit. The interest rate alone does not tell the full cost story. For more on understanding financing costs, our guide on APR vs. factor rate can help.
How Repayment Works
Repayment structures for business lines of credit vary by lender. Here are the most common setups:
- Weekly or biweekly payments: Common with online lenders. Payments are often auto-debited from your business bank account.
- Monthly payments: More typical with traditional banks and SBA lines of credit.
- Interest-only payments during the draw period: Some lines allow you to pay only the interest during the draw period, with principal repayment starting afterward.
With a revolving line, every dollar of principal you repay becomes available to borrow again. Paying down your balance faster frees up more credit and reduces total interest costs.
Some lenders set minimum payment requirements, while others allow you to pay off your balance in full at any time without penalties. Ask about prepayment terms before you sign.
Secured vs. Unsecured Business Lines of Credit
Business lines of credit come in two forms: secured and unsecured.
A secured line of credit requires collateral. This could be business equipment, inventory, accounts receivable, or real estate. Because the lender has an asset backing the credit, secured lines may come with higher limits and potentially more favorable terms.
An unsecured line of credit does not require specific collateral, though many lenders still require a personal guarantee. Without collateral, lenders take on more risk, so unsecured lines may have stricter qualification requirements and lower credit limits.
The right choice depends on your situation. If you have assets to pledge and need a larger credit line, secured may be the way to go. If you prefer not to tie up assets, unsecured offers more flexibility. Read more in our comparison of secured vs. unsecured business loans.
Common Qualification Requirements
Qualification criteria differ from lender to lender, but many lenders evaluate similar factors when reviewing a business line of credit application:
- Time in business: Many lenders look for at least six months to two years of operating history. Newer businesses may still find options, though terms can differ.
- Annual revenue: Revenue thresholds vary widely. Some online lenders work with businesses generating $100,000 or more per year, while banks may set higher minimums.
- Credit score: Both personal and business credit scores can factor into the decision. Stronger credit profiles typically open the door to higher limits and more favorable terms. See our post on credit score for a business line of credit for a detailed breakdown.
- Documentation: Expect to provide bank statements, tax returns, financial statements, and possibly a business plan. Our guide on documents required for a business loan covers what to prepare.
Keep in mind that meeting these general benchmarks does not guarantee approval. Each lender has its own underwriting criteria, and terms will vary based on your specific financial profile.
When a Business Line of Credit Makes Sense
A line of credit is not the right tool for every situation, but it excels in several common scenarios:
- Managing cash flow gaps. If your business has uneven revenue cycles, a line of credit can bridge the gap between payables and receivables. Learn more in our guide on cash flow management for small businesses.
- Covering seasonal expenses. Retail businesses that need to stock up on inventory before a busy season can draw funds, then repay as sales come in.
- Handling unexpected costs. Equipment breakdowns, emergency repairs, or sudden opportunities all call for quick access to capital.
- Purchasing inventory. Rather than tying up all your cash in inventory, a line of credit lets you buy what you need and repay as products sell.
The common thread is flexibility. If you need a fixed amount for a specific purchase like real estate or a large piece of equipment, a term loan may be a better fit. But for ongoing, variable capital needs, a line of credit is hard to beat.
Business Line of Credit vs. Other Financing Options
Here is a quick comparison of how a business line of credit stacks up against other common financing products:
| Feature | Line of Credit | Term Loan | Working Capital Loan | Invoice Factoring |
|---|---|---|---|---|

| Interest | On drawn amount only | On full loan amount | On full loan amount | Factoring fee per invoice |
| Repayment | Flexible, replenishes credit | Fixed schedule | Fixed schedule | Collected from customers |
| Best for | Ongoing variable needs | Large one-time purchases | Short-term cash needs | Businesses with slow-paying clients |

How to Apply for a Business Line of Credit
Applying for a business line of credit is straightforward, especially when you prepare ahead of time:
- Assess your needs. Determine how much credit you need and what you will use it for. This helps you find the right product and lender.
- Gather your documentation. Have bank statements, tax returns, financial statements, and business registration documents ready.
- Compare lenders. Different lenders offer different terms, limits, and fee structures. A marketplace like BreadRoute can help you compare multiple lender options in one place rather than applying separately to each one.

- Review your offer. Before accepting, read the terms carefully. Look at the interest rate, fees, draw period length, and repayment structure.

With a revolving line of credit, your available balance replenishes as you repay, so you can borrow again without reapplying.
You pay interest only on the amount you have drawn, not on the full credit limit. If you have a 50,000 line of credit and draw $10,000, interest accrues on that $10,000 only. The remaining $40,000 in available credit does not cost you anything until you use it.
Yes, if you have a revolving line of credit. As you repay what you have borrowed, that amount becomes available to draw again. This cycle can continue throughout the draw period. Non-revolving lines do not replenish after repayment.
There is no single credit score requirement that applies to all lenders. Many traditional lenders look for personal credit scores in the mid-600s or higher, while some online lenders may work with lower scores. Stronger credit profiles generally lead to higher limits and more favorable terms. Visit our post on credit score for a business line of credit for more detail.
The draw period is the timeframe during which you can access funds from your line of credit. Draw periods vary by lender and can range from 12 months to several years. Some revolving lines remain open indefinitely as long as the account is in good standing. Once the draw period ends, you typically enter a repayment-only phase.
Most business lines of credit are revolving, meaning your available credit replenishes as you repay. Non-revolving lines exist but are less common. When shopping for a line of credit, confirm whether the product is revolving so you understand how your access to funds will work over time.
Common fees include draw fees (charged each time you withdraw funds), annual or maintenance fees, origination fees, and in some cases inactivity fees. Fee structures vary significantly between lenders, so reviewing the full cost beyond just the interest rate is essential before committing.
Some startups can qualify, though options may be more limited. Many lenders prefer businesses with at least six months to two years of operating history. Startups with strong personal credit, solid revenue, or collateral to offer may find lenders willing to work with them. Exploring multiple lender options through a marketplace can help identify the right fit.
