Working Capital Loans vs Overdraft: Which One Actually Supports Growth?
When cash gets tight, most banks push you toward an overdraft. It feels flexible, familiar and easy to tweak. But for many businesses, a structured working capital loan is actually the cleaner option for growth, especially when you’re already dealing with cash flow warning signs like the ones in 5 Cash Flow Warning Signs Your Business Needs a Finance Safety Net.
This guide breaks down how working capital loans and overdrafts are built, how they’re priced, and how they behave over time. We’ll also show where tools like a business line of credit and invoice finance fit in, using the same simple framework from our Business Cashflow System article.
1. Structure: term loan vs revolving credit
A working capital loan is a term facility: you borrow a lump sum, repay it over an agreed schedule and have a clear end date. An overdraft (or informal line on your transaction account) is revolving—you can dip in and out up to a limit, with no set finish line.
Term-style working capital loans work well when you’re clearing a known problem (for example, ATO debt or supplier arrears) or funding a defined project. Overdrafts are better for short, temporary timing gaps in cash flow. If you’re using an overdraft to permanently carry old debt, you’re likely paying more interest than you need to.
2. Cash flow impact: discipline vs drift
A working capital loan comes with a repayment schedule, so your cash flow plan automatically includes clearing that balance. That built-in discipline is a big reason many owners feel calmer once they move chronic overdraft debt into a term loan.
With an overdraft, there’s no forced reduction. Minimum repayments are often just interest, so it’s easy for the limit to stay near max while you hope “one big invoice” will knock it down. If that sounds like your world, cross-reference this article with How to Use a Business Line of Credit Without Getting Stuck in Debt.
3. Pricing: headline rate vs total cost
Overdrafts are usually on a variable rate, and the headline rate can look sharp—especially if you only glance at the number on the website. But you also need to factor in line fees, unused limit fees and higher margins once your risk profile changes.
Working capital loans might be either variable or fixed rate, often with clearer total cost over the life of the loan. When we compare options for clients at Business Loans, we look at the real dollar cost over 12–36 months, not just the starting rate.
4. Growth strategy: how each fits into a bigger system
On their own, both tools are blunt. Inside a simple system, they start to make sense:
- Use invoice finance to unlock cash stuck in receivables.
- Use a business line of credit or small overdraft for short-term swings.
- Use working capital loans to clear big issues or fund defined growth moves.
That mix is exactly what we unpack in the Invoice Finance for Growing SMEs article as part of this Monday cash flow cluster.
5. When to choose which: quick scenarios
A few simple rules of thumb:
- Clearing ATO debt, rent arrears or one-off supplier pressure? A working capital loan is usually cleaner than stretching an overdraft.
- Covering payroll while you wait for invoices to pay? A small overdraft or business line of credit can make sense, especially with good cash flow tracking.
- Funding ongoing growth? Combine working capital loans with invoice finance and a modest overdraft or LOC, instead of relying on one tool for everything.
If you’re still unsure where your situation fits, the Business Owners Finance Hub and our Business Cashflow System guide give more worked examples.

Frequently asked questions about working capital loans vs overdraft
A working capital loan is a term facility with fixed repayments and an end date. An overdraft is revolving—you use it when you need it and pay interest on the drawn balance. Loans suit defined problems or projects, overdrafts suit short-term cash flow timing gaps.
For larger ATO or supplier balances, a structured working capital loan is usually cleaner. It forces the balance down over time, instead of leaving it sitting in an overdraft where it can linger and cost more interest.
Most overdrafts are on a variable rate, so your interest cost can change over time. Some working capital loans offer a fixed rate instead, which can give more predictable repayments.
Yes. Many businesses use a term working capital loan for big, defined needs and a smaller overdraft or business line of credit for day-to-day swings in cash flow.
If slow-paying customers are the real problem, invoice finance is often better than simply lifting your overdraft limit. It converts invoices into working capital and can sit alongside a loan or overdraft in a broader funding mix.
