A working capital loan gives you a lump sum upfront with fixed repayments, while a line of credit lets you draw and repay funds as needed, paying interest only on what you use.
How Working Capital Loans Function in Practice
A working capital loan delivers a set amount of funding in a single transaction. You receive the full loan amount at settlement, then repay it over an agreed term, typically between six and 24 months. Interest accrues on the entire balance from day one, and your repayments stay consistent throughout the loan term.
Consider a manufacturing business securing a $150,000 working capital loan to purchase raw materials for a confirmed contract. The funds arrive within days of approval, the materials are ordered, production begins, and the loan is repaid from invoices as they're settled. The business knows exactly what it owes each month, which makes budgeting predictable. The structure works when you have a specific funding need, a clear repayment source, and confidence that you won't need to access additional funds during the term.
This type of funding suits businesses with defined expenses and reliable income cycles. It's also more commonly available on an unsecured basis for established businesses with consistent turnover, meaning you may not need to offer property or equipment as security.
When a Line of Credit Offers More Control
An unsecured business line of credit works more like an overdraft. You're approved for a limit, draw what you need when you need it, and repay at your own pace within the agreed terms. Interest is charged only on the outstanding balance, and once you repay, that capacity becomes available again.
This structure gives you ongoing access without reapplying each time your circumstances change. A transport operator approved for a $100,000 line of credit might draw $40,000 to cover fuel and wages during a quiet fortnight, repay it once invoices clear, then draw $60,000 the following month to repair two trucks after a breakdown. The same facility supports both needs without doubling up on fees or applications.
Lines of credit are particularly valuable for businesses that experience uneven income, seasonal demand, or irregular expenses. You're not locked into repaying funds you haven't used, and you're not penalised for repaying early. The flexibility comes at a cost though, with interest rates on lines of credit typically sitting higher than those on term loans, reflecting the on-demand nature of the product.
Comparing Interest Costs Across Both Structures
Interest on a working capital loan is calculated on the full amount from the outset. Even if you only needed half the funds for the first few months, you're paying interest on the entire balance. That makes the total cost higher if your actual drawdown is lower than the approved amount.
With a line of credit, you only pay interest on what you've drawn. If you're approved for $80,000 but only use $30,000 in the first month, your interest charge reflects that lower figure. As you repay, the interest drops accordingly. Over time, this can result in lower overall costs, particularly if your funding needs fluctuate or if you repay quickly.
That said, the higher interest rate on lines of credit can offset the savings if you consistently run a high balance. The structure favours businesses that draw intermittently and repay promptly, not those that treat the facility as permanent working capital.
Which Product Suits Seasonal or Project-Based Businesses
Businesses with seasonal income patterns often benefit more from a line of credit than a lump sum loan. A landscaping business in Western Australia might see demand peak from September through to March, then slow considerably over winter. A line of credit allows that business to draw funds during the off-season to cover wages and equipment maintenance, then repay the balance once invoices start flowing again in spring.
A working capital loan, by contrast, suits businesses undertaking a specific project or covering a one-off expense. If you're fulfilling a large order, purchasing stock for a known sales period, or covering a gap between contract milestones, a loan gives you certainty around repayment and total cost.
The key difference is whether your funding need is episodic or ongoing. If you're managing irregular expenses across an extended period, cashflow solutions that offer revolving access tend to deliver better value. If you're funding a single event or purchase, a term loan is usually more cost-effective and keeps your obligations contained.
Approval Criteria and What Lenders Prioritise
Lenders assess working capital loans and lines of credit differently. For a term loan, they focus on your ability to service fixed repayments from current income. They'll review recent financials, turnover, profit margins, and existing debt commitments. If your cashflow can absorb the monthly repayment comfortably, approval is usually straightforward.
For a line of credit, lenders also consider how you'll manage variable drawdowns. They want to see that your business can handle fluctuating balances without overextending. That means stronger scrutiny of your cash conversion cycle, debtor days, and how quickly you turn stock or invoices into cash. Businesses with longer payment terms or slower stock turnover may face lower limits or higher rates, even if their overall income is solid.
Both products are available on an unsecured basis, but eligibility tightens if your business is newer, operates in a high-risk industry, or carries significant existing debt. In those cases, lenders may require a director's guarantee, or steer you toward asset finance or inventory loans where security strengthens the application.
How to Decide Between the Two
Start with the question: do you need a set amount now, or ongoing access over time? If it's the former, a working capital loan is usually the right fit. If your needs shift week to week, or if you want the option to draw, repay, and redraw without reapplying, a line of credit makes more sense.
Next, consider how predictable your income is. Businesses with consistent monthly revenue can handle fixed loan repayments without strain. Businesses with seasonal peaks, project-based income, or long payment cycles benefit from the flexibility of a line of credit, where repayments adjust to match actual drawdowns.
Finally, compare the interest cost under realistic usage. If you're likely to use most of the approved limit for an extended period, a working capital loan will usually cost less. If you'll be drawing intermittently and repaying quickly, a line of credit keeps your costs tied to actual usage rather than approved capacity.
Both options address genuine cashflow needs, but the structure you choose should reflect how your business earns and spends. Choosing the wrong one doesn't just increase costs, it can create repayment pressure at exactly the wrong time.

Frequently Asked Questions
What is the main difference between a working capital loan and a line of credit?
A working capital loan provides a lump sum with fixed repayments over a set term, while a line of credit lets you draw and repay funds as needed, paying interest only on the amount you use. The loan suits one-off expenses, while the line of credit suits ongoing or irregular funding needs.
Which option costs less in interest?
A working capital loan typically has a lower interest rate, but you pay interest on the full amount from day one. A line of credit has a higher rate but you only pay interest on what you've drawn, which can result in lower overall costs if you repay quickly or use the facility intermittently.
Can I get either product without offering security?
Yes, both working capital loans and lines of credit are commonly available on an unsecured basis for established businesses with consistent turnover. Lenders may require a director's guarantee, but you won't necessarily need to offer property or equipment as security.
Which product suits a business with seasonal income?
A line of credit is usually better for businesses with seasonal income because you can draw funds during quieter months and repay when cashflow improves. A working capital loan requires fixed repayments regardless of income fluctuations, which can create pressure during off-peak periods.
How quickly can I access funds from either option?
Both products can settle within days of approval, depending on the lender and the completeness of your application. Working capital loans typically involve a single drawdown at settlement, while a line of credit gives you ongoing access once the facility is in place.
