Merchant cash advance vs business overdraft: speed vs cost
A merchant cash advance is fast and asks for almost nothing upfront. A business overdraft is usually cheaper, but wants a real banking relationship behind it. Here’s what that trade-off costs you.
General information only
A merchant cash advance provides an upfront lump sum against your future card sales, repaid as a fixed percentage of what you take rather than a fixed monthly instalment. A business overdraft is a standing limit on your transaction account: draw below zero, repay, draw again, and pay interest only on what you’ve used. The common assumption is that an MCA is only for businesses in trouble. It isn’t. Plenty of well-run businesses use one deliberately, for speed and simplicity.
What’s different between them?
An MCA rarely requires asset or property security. It’s secured against your future card sales instead, and approval is usually fast, with lighter documentation than most finance. An overdraft has been the classic bank product for decades, but a growing group of non-bank lenders now write overdraft facilities too, often to business profiles the major banks won’t touch.
The trade-off sits in cost and access. An MCA is usually more expensive than a business overdraft or line of credit. That’s the price of speed and minimal paperwork, and it’s not worth paying if you don’t need either.
An MCA is rarely about property. It’s secured against future card sales. An overdraft is a standing limit on your transaction account.
You have trading history and time to arrange it
Usually the cheaper facility for the same working capital need, provided you’re prepared for a non-bank lender’s ongoing bank-statement access requirement and don’t already have another working capital facility running.
Speed and minimal paperwork matter most
Fast to arrange, rarely needs asset security, and suits a business without the time (or the profile) for a traditional application.
| What matters | Merchant cash advance | Business overdraft |
|---|---|---|
| Security | Rarely requires asset or property, secured against future card sales | Standing limit on your transaction account |
| Approval | Fast, less stringent documentation | Requires ongoing bank-statement access |
| Repayment | Fixed percentage of card sales, often daily or weekly | Draw and repay as needed, interest only on the amount used |
| Amount range | Scales with your card sales volume, no fixed published range | Up to $1,000,000, terms from 12 months to 5 years |
| Cost | Usually higher than an overdraft or line of credit | Generally cheaper for the same working capital need |
What does an MCA cost against an overdraft?
You can’t compare them until you convert one, because the two are priced in units that don’t meet. An overdraft carries an interest rate on what you’ve drawn. A merchant cash advance carries a factor rate, a fixed multiplier on the advance. That isn’t an interest rate, and it behaves nothing like one.
Take the worked example from our merchant cash advance page: a $50,000 advance at a factor rate of 1.20 means you repay $60,000, so the cost is a fixed $10,000, or 20% of the advance, no matter how long it takes. Converting that fixed fee into an annual cost of funds is what makes it comparable:
| Time to repay | Cost as a share of the advance | True annual cost of funds |
|---|---|---|
| 6 months | 20% | about 65.7% p.a. |
| 9 months | 20% | about 45.7% p.a. |
| 12 months | 20% | about 35.1% p.a. |
| 18 months | 20% | about 23.9% p.a. |
Now the published overdraft side, from each lender’s own product pages: Westpac from 8.11% p.a. plus a 1.20% line fee, CommBank 8.75% secured or 14.80% unsecured, each plus a 1.70% line fee. Fully drawn, that’s roughly 9.3% to 16.5% all-in.
So an MCA repaid over six months costs in the order of four times CommBank’s unsecured overdraft and seven times Westpac’s. That’s the number the comparison exists to surface, so here’s exactly how it’s built. The annual figures above are the internal rate of return on repaying $60,000 in level instalments against $50,000 received. A real MCA takes a percentage of daily card takings instead, so your schedule will be lumpier. On the overdraft side, interest applies to the drawn balance while the line fee applies to the whole limit, so 9.3% to 16.5% assumes you stay fully drawn. Leave the limit largely unused and the fee is a heavier share of what you borrowed.
The other difference matters just as much, and it runs the opposite way to every other product on this site. Because the MCA fee is fixed rather than accruing, trading well makes it more expensive, not less. A strong month clears the same $10,000 faster, which raises the annual cost rather than lowering it. On an overdraft, paying down early reduces what you pay. If your card takings are strong and reliable, that strength is the reason an MCA is an expensive way to borrow, and usually the reason you’d qualify for something cheaper.

Can you run both at the same time?
Not usually. Most overdraft providers won’t allow another working capital facility alongside theirs without signing off on it first, and some will foreclose, or ask for the balance back within 30 to 90 days, if they find one after the fact. Get the approval first, then sign. Where an MCA does make sense alongside a bank relationship is as a short-term, deliberate tool, not a permanent fixture in how you fund the business.
We’re filming a segment with one of our lending partners on when they’d recommend an MCA over an overdraft, and where the line sits for a well-run business. Once it’s up, it’ll sit here.
Choose an overdraft if
- You have the trading history to support it
- You’re comfortable with ongoing bank-statement access
- You don’t already have another working capital facility running
Choose an MCA if
- You need funding fast, with minimal paperwork
- Card sales make up a meaningful share of your revenue
- You’re using it as a deliberate, short-term tool
Using an MCA as a bridge
Some businesses use an MCA deliberately as a bridge: fast capital now, while building the trading history and bank statement conduct that gets an overdraft or line of credit approved on better terms. That’s a legitimate use of the product. What doesn’t work is treating an MCA as the permanent facility rather than the stepping stone, because the cost difference compounds the longer it runs.
Andrew’s rule of thumb: an MCA suits a café, restaurant or similar that wants quick capital against its daily EFTPOS takings. A bigger retail brand with a few years of decent cash flow, borrowing for stock, is usually better on an overdraft, so it isn’t handing a percentage of every day’s sales to a lender.
