What it is
A line of credit works like a business credit card with a much higher limit and a lower rate. You are approved for a maximum, borrow what you need when you need it, and pay interest only on what is outstanding. As you repay, the room opens up again.
That makes it ideal for timing gaps: waiting on a customer payment, buying inventory ahead of a busy season, or covering a slow month. It is a poor fit for buying equipment or real estate, because lines are shorter-term and usually renewed periodically.
Illustration at the same rate. The line costs less because you pay interest only on what you have drawn, which is the point of a revolving line.
A good fit if you want
- Cash-flow gaps and seasonal businesses
- Having a safety net without paying interest on idle money
- Borrowing needs that are hard to predict
Probably not the right tool if
- Financing a long-lived asset
- Borrowers who tend to leave the balance near the limit, which can lead lenders to cut the line
Typical requirements
- Business bank statements and financials
- Often a personal guarantee
- Collateral such as receivables, inventory or a blanket lien
- SBA CAPLines follow the same eligibility as a 7(a)

Common questions
What is the difference between a term loan and a line of credit?
A term loan gives you the full amount up front and charges interest on all of it. A line lets you borrow in pieces and pay interest only on what you use.
Can the lender cut my line?
Yes. Lines are commonly reviewed and renewed, and lenders can reduce or freeze them if your finances weaken.
