What this topic is
A line of credit is revolving borrowing: you're approved for a limit, draw any amount up to it as needed, repay, and draw again — paying interest only on what you've drawn. It's different from a term loan's lump sum you pay interest on immediately.
Why it matters
Because you pay only for what you use, a well-managed line of credit is one of the most useful, cost-effective financing tools — ideal for smoothing cash flow, bridging timing gaps, and holding as a safety net for emergencies.
Who should learn it
Almost any business — for cash-flow smoothing, short-term needs, and a safety net.

- Understand a line of credit: revolving, pay only for what you use
- See its ideal use: smoothing cash flow and a safety net
- Use it for short-term, self-liquidating needs — not permanent losses
- Read a maxed-out line as a warning sign
Prerequisites
Common misconception
"A line of credit is just a loan — draw it all and use it however." A line of credit is revolving — you draw, repay, and draw again, paying interest only on what you've drawn — which makes it ideal for short-term, self-liquidating needs (a gap soon repaid from incoming cash). Use it to fund ongoing losses or a permanent purchase, and you quietly turn a flexible safety net into a maxed-out, perpetual debt. A revolving line is a tool for timing; a maxed-out one is a warning sign.
