Revolving credit is a credit line you can borrow against, repay, and borrow against again up to a set limit, with no fixed end date and no fresh approval needed each time you draw. A credit card is the everyday example: as you pay down the balance, that headroom becomes available to spend again. Interest is charged only on the amount you actually owe, not the whole limit.
For a business, revolving credit is a flexible buffer for the gaps that fixed financing handles badly: a slow-paying customer, a stock order that lands before the cash does, payroll falling due the week before a big invoice clears. Because the line refills as you repay it, it is built for recurring, unpredictable needs rather than a single large purchase.
Borrow, repay, repeat.The line refills as you pay it down, with no new approval for each draw.
You pay for what you use.Interest applies only to the drawn balance, not the full limit.
Built for swings, not lumps.Ideal for working-capital gaps; a term loan suits one large, fixed purchase.
A lender sets a credit limit, you draw any amount up to it, interest accrues on the outstanding balance, and each repayment restores that much available credit. The cycle has no scheduled finish: as long as you stay within the limit and meet the minimum payments, the facility stays open and reusable. That is the single feature that defines it, and the one that separates it from every fixed-term loan.
Most revolving facilities carry a few standard mechanics worth knowing before you draw.
A minimum monthly paymentOften a small percentage of the balance, which keeps the account in good standing.
A possible commitment feeSome business lines charge a non-utilisation fee on the unused portion, paying the lender to hold the headroom.
A variable interest rateThe cost of carrying a balance can move with the wider rate environment, so it is rarely fixed.
Carry a balance month to month and the interest compounds quickly, which is why revolving credit rewards discipline and punishes drift.
Revolving credit is a reusable line you draw on as needed, while a term loan is a single lump sum repaid on a fixed schedule. The two solve different problems, and using the wrong one is an expensive mistake. A term loan suits a known, one-off cost like a vehicle or a fit-out, where the amount and timing are clear up front. Revolving credit suits the moving target of day-to-day cash flow.
| Feature | Revolving credit | Term loan |
|---|---|---|
| Access to funds | Draw repeatedly up to a limit | One lump sum at the start |
| Repayment | Flexible, minimum payment then your pace | Fixed instalments over a set term |
| End date | Open-ended, renews on review | Fixed maturity date |
| Interest charged on | Only the drawn balance | The full borrowed amount |
| Best for | Working capital and cash-flow gaps | A single, known purchase |
The practical rule: if you cannot say in advance exactly how much you will need or when, revolving credit fits. If you can name the figure and the date, a term loan is usually cheaper and more predictable. Many businesses run both, a term loan for assets and a revolving line as a cash-flow cushion behind it.
Revolving credit shows up in several familiar forms, and the common thread is reusability: each repayment frees up capacity to borrow again.
Business credit cardThe simplest form: a limit, a monthly statement, and a balance you can carry or clear.
Business line of creditWorks the same way but usually at a higher limit and lower rate, drawn to your bank account.
Bank overdraftLets the account dip below zero up to an agreed ceiling, then refills as you top it back up.
A supplier accountBuying on credit terms as you settle earlier invoices behaves like revolving credit, with no bank involved.
Contrast that with invoice finance or a fixed loan, where the facility is tied to specific invoices or a specific sum and does not simply refill.
Unsecured revolving credit relies on your creditworthiness alone, while secured revolving credit is backed by an asset such as receivables, inventory, or property. Most business credit cards and smaller lines are unsecured, which makes them faster to arrange but typically smaller and pricier. Larger revolving facilities are often secured, with the lender taking a charge over assets to reduce its risk, which usually buys a higher limit and a lower rate.
The trade-off is straightforward. Unsecured credit keeps your assets unencumbered but costs more and caps lower. Secured credit unlocks more borrowing on better terms, at the price of pledging something the lender can claim if you default. Which makes sense depends on how much headroom you need and what you are comfortable putting up against it.
Revolving credit's strength is flexibility, but the same flexibility makes it easy to misuse. Used as a short-term bridge, repaid quickly, it is one of the cheapest forms of business flexibility available. Leaned on to fund ongoing losses, it can quietly become permanent, expensive debt.
Instant access to funds without reapplying each time.
You only pay interest on what you draw, and nothing to hold an unused line.
Smooths the timing mismatch between paying suppliers and getting paid.
Covers the unexpected as a fast, short-term bridge.
No fixed repayment forcing the balance down, so it can become permanent debt.
Variable interest compounds on a balance that never clears.
Rates are usually higher than a secured term loan.
Funding ongoing losses, not timing gaps, is how businesses drift into trouble.
The tool is only as good as the discipline behind it: a short-term bridge repaid quickly, not a standing overdraft on the future.
The discipline that keeps revolving credit cheap is keeping utilisation low and clearing the balance often. Utilisation, the share of your limit you are using, drives both interest cost and how lenders read your risk. A line that sits near its ceiling month after month signals strain and can nudge future borrowing costs up, so treat the limit as a buffer rather than a target.
For a business, the fastest way to lean on the line less is to get paid faster. Every invoice that clears on time is cash you do not have to draw down to cover the gap. Tightening collections, so money arrives closer to the due date, shrinks the working-capital hole that revolving credit exists to fill, and that is squarely what accounts receivable automation is for. Steady reminders and clean follow-up mean less reliance on borrowed cash, lower interest, and a credit line kept in reserve for when you genuinely need it.
