Merchant cash advance vs bank overdraft: a detailed comparison
By Helm, Business Funding Specialists
- Overdrafts charge daily interest and can be reduced or withdrawn at any time by the bank
- MCAs have a fixed total cost and repayments that flex with your card revenue
- Overdrafts suit short-term cash flow gaps while MCAs suit larger investments
- MCAs are easier to access for businesses that struggle with bank approval
Business overdrafts have been the default working capital tool for UK businesses for decades. But they come with limitations that are becoming increasingly problematic. Banks can reduce or withdraw your facility with little notice, fees have risen, and approval has become harder.
A merchant cash advance offers a different approach. This guide provides a thorough comparison to help you decide which product is right for your business.
How each product works
A bank overdraft lets you spend beyond your account balance up to an agreed limit. You pay interest on the amount you use, typically calculated daily. The bank can review, reduce, or remove the facility at any time.
A merchant cash advance provides a lump sum upfront that you repay through a fixed percentage of your daily card transactions. The total cost is set from the start and does not change.
Cost comparison
The cost structures are fundamentally different, which makes direct comparison tricky. Overdrafts appear cheaper on paper because they quote low daily rates, but the costs add up over time, especially if you consistently use the facility.
| Feature | Bank overdraft | Merchant cash advance |
|---|---|---|
| Pricing model | Daily interest on balance used | Fixed factor rate |
| Typical cost | 15% to 40% EAR | Factor rate 1.15 to 1.5 |
| Cost certainty | Variable | Fixed from day one |
| Arrangement fees | Often £100 to £500+ per year | Usually none |
| Renewal fees | Annual review fees common | None |
| Unauthorised usage fees | Significant penalty charges | Not applicable |
Access and approval
Getting an overdraft has become increasingly difficult. Banks have tightened criteria and many smaller businesses find their applications rejected or their limits set too low to be useful.
| Feature | Bank overdraft | Merchant cash advance |
|---|---|---|
| Approval time | 1 to 4 weeks | 24 to 48 hours |
| Documentation | Extensive business and personal financial data | Card processing statements |
| Credit score importance | High | Low |
| Personal guarantee | Often required | Typically not required |
| Security required | Sometimes | None |
| Typical limit | £1,000 to £25,000 | £10,000 to £300,000 |
The withdrawal risk
One of the biggest risks with a bank overdraft is that the bank can reduce or withdraw the facility at any time. This has happened to many UK businesses, sometimes at the worst possible moment. During economic downturns, banks frequently review and cut overdraft facilities.
With a merchant cash advance, there is no risk of the funding being withdrawn. Once you have received the advance, the money is yours. The repayment continues automatically through your card transactions until the agreed total has been collected.
When an overdraft makes more sense
An overdraft remains a useful tool in certain situations.
- Covering very short-term cash flow gaps of a few days or weeks
- Managing timing mismatches between payments received and bills due
- Small, irregular working capital needs where you dip in and out quickly
- Businesses with strong bank relationships and secure, long-standing facilities
When an MCA makes more sense
A merchant cash advance is the stronger choice for many scenarios.
- Larger funding needs that exceed your overdraft limit
- Investments that will generate a return, like equipment or refurbishments
- Businesses that have been declined for an overdraft or had their facility reduced
- When you want cost certainty with no variable charges
- Situations where you need funds quickly and cannot wait weeks for bank approval
Frequently asked questions
Is a merchant cash advance more expensive than an overdraft?
It depends on usage. For short, infrequent dips into an overdraft, the overdraft may be cheaper. For sustained use or larger amounts, a merchant cash advance often works out more cost-effective because the total cost is fixed and there are no ongoing fees.
Can I use both at the same time?
Yes. Many businesses maintain an overdraft for day-to-day cash flow management while using a merchant cash advance for larger, specific investments.
Will taking an MCA affect my overdraft?
A merchant cash advance is separate from your banking relationship. However, if your bank notices a new financial obligation, they may review your overdraft facility.
Can the bank really remove my overdraft without warning?
Yes. Banks can reduce or remove overdraft facilities with relatively short notice. This is a contractual right that most banks reserve, and it happens more frequently than many business owners realise.
