Working capital loan vs line of credit: what's the difference?
A working capital loan is a lump sum you take once and repay on a fixed schedule; a line of credit is a revolving limit you draw, repay, and draw again as needed. Use a loan for a known one-time gap, and a line of credit for recurring or unpredictable cash-flow swings.
The core difference
A working capital loan drops a fixed amount into your account and you repay it over a set term, whether or not you end up needing all of it. A line of credit sets a ceiling you borrow against only when you draw, and you pay interest just on the outstanding balance. One is a single event with a defined start and end; the other is a reusable buffer that refills as you repay. That structural difference — lump sum versus revolving limit — is what makes each better suited to a different kind of cash-flow problem, and it drives everything else, from what they cost to how a lender sizes them.
When each one fits
Choose a working capital loan when the need is specific and one-time — a big material order, a payroll gap on a known project, mobilizing to a new site. You know the amount and you'll clear it as a defined inflow lands. Choose a line of credit when your cash flow is lumpy and you want a standing cushion for the next slow-pay stretch, a seasonal dip, or an unexpected cost you can't predict the timing of. The rule of thumb: a loan solves a problem you can see and size today; a line stands ready for the ones you can't.
What each one costs
A working capital loan is priced as a rate or a simple factor on the full amount, and you pay for every dollar over the whole term even if the money sits idle. A line of credit charges interest only on what's drawn, so for intermittent needs it's usually cheaper in practice, though it may carry an annual or monthly fee whether or not you use it. The honest comparison is total dollar cost over how you'll actually use the money — a fully-used loan can beat a line, while a line wins when you dip in and out. Convert any quote to an annualized cost before deciding.
How lenders size and secure each
Both products size to revenue and cash flow more than to collateral, but the emphasis differs. A term loan is underwritten against your ability to repay a fixed schedule, so lenders weight recent revenue and existing debt heavily. A line of credit is ongoing exposure, so lenders care about the stability of your bank-account behaviour — steady deposits, few NSFs — because they're betting on you managing a revolving balance responsibly. Either can be unsecured (higher rate, faster, smaller) or secured against receivables or a general security agreement (lower rate, larger, slower to arrange).
Using both together — and the common mistake
Many established trades run both: a line of credit for the routine ebb and flow, and a term advance for the occasional larger push the line can't comfortably absorb. Used that way they complement each other. The common mistake is forcing one to do the other's job — carrying a permanent balance on a line that should have been a term loan (you end up paying revolving rates on money you never repay), or taking a lump-sum loan for a need that comes and goes (you pay interest on idle cash). Match the tool to the shape of the need and both stay cheap; misapply them and you quietly overpay.
Which should you ask for first?
If you're unsure, a line of credit is the more flexible starting point for most trades and owner-operators, because it covers the widest range of timing gaps and only costs you when you draw. Graduate to a term working-capital advance when a specific, larger need appears that the line can't cover without maxing out. Lenders look at your total debt when sizing either, so opening a modest line and using it well also builds the track record that supports a bigger facility later. Start with the buffer, add the lump sum when a concrete need justifies it.
A worked example
Say you run a small mechanical contracting shop with steady monthly revenue and two recurring headaches. The first is a predictable one: every quarter you carry payroll for two to three weeks before a big client's progress draw clears — a known, repeating gap. The second is unpredictable: a truck blows a transmission, or a supplier suddenly wants payment up front on a large order. The recurring payroll gap is textbook line-of-credit territory — you draw a portion of your limit for a couple of weeks, repay when the draw lands, and pay interest only on those weeks. The one-off supplier bill or repair, if it's large and you'll clear it against a specific upcoming payment, can suit either, but a working-capital advance keeps your line free for the payroll cycle you know is coming. The mistake would be funding the routine quarterly gap with a fresh lump-sum loan each time (slow, and you pay for idle cash) or letting a one-off emergency permanently occupy your line so it isn't there for payroll. Matching each need to the right tool keeps both cheap and available.
Frequently asked questions
- Which is cheaper, a loan or a line of credit?
- A line of credit is often cheaper in practice because you pay interest only on what you draw. A term loan can be cheaper per dollar if you'd fully use the funds anyway.
- Can I have both?
- Yes — many businesses keep a line of credit for routine swings and take a working capital loan for a specific larger need. Lenders will look at total debt when sizing either.
- Do I need collateral for either one?
- Not necessarily. Both come in unsecured versions that lean on revenue and cash flow, at higher rates and smaller amounts. Secured versions cost less and can be larger but require collateral.
