Both business credit cards and business overdrafts give you access to funds you don't currently have - but they're fundamentally different products designed for different situations. Here's an honest comparison to help you choose the right one.
The key differences at a glance (2026)
| Feature | Business Overdraft | Business Credit Card |
|---|---|---|
| Credit limit | Up to $500,000 | Typically $5,000-$100,000 |
| Interest rate (2026) | From 14.55% p.a. indicative, charged on the drawn balance only | Typically 15-23% p.a. on carried balances |
| Interest-free period | None - interest from day of drawdown | Up to 55 days interest-free if paid in full |
| Fees | Line fee on the facility limit (often around 0.5-2% p.a.); no broker fee | Annual card fees typically $60-$450; cash advance fees; surcharges when paying suppliers by card |
| Reusability | Revolving - draw, repay, redraw without reapplying | Revolving - repay and spend again up to the limit |
| Credit score impact | One enquiry via broker; lender matched to your profile first | Card enquiry plus high utilisation can drag your score down |
| Cash access | Funds land in your bank account - pays wages, suppliers, ATO | Card payments only; cash advances attract higher rates and fees |
| Repayments | Fixed weekly (revolving) | Minimum monthly payment |
| Best for | Large, short-medium term cash flow gaps | Small, day-to-day business expenses |
| Rewards | None | Points, cashback, frequent flyer miles |
Overdraft rates start from 14.55% p.a. through OverdraftMe's 50+ lender panel and are indicative only - subject to change based on credit assessment, business profile, revenue, trading history and lender criteria. Credit card figures are market-typical ranges for Australian business cards in 2026.
When a business overdraft wins
A business overdraft is significantly better than a credit card when:
- You need a large amount - credit cards rarely offer limits above $100,000. An overdraft can go to $500,000.
- The gap lasts more than 55 days - once you're past the interest-free period on a credit card, rates jump to 15–20%+. An overdraft's daily rate is typically far lower for medium-term borrowing.
- You need funds in your bank account - a credit card can't pay wages or transfer to suppliers. An overdraft can.
- You need predictable weekly repayments - minimum credit card payments don't reduce the principal meaningfully, creating a debt trap.
When a business credit card wins
A credit card can be better than an overdraft when:
- You can pay it off within 55 days - the interest-free period makes it genuinely free short-term credit
- You want rewards on business spending - points and frequent flyer miles on everyday expenses add up
- The amounts are small - for expenses under $5,000 that you'll repay quickly, a credit card is simpler
- You need a card for employee expenses - issuing staff cards on a business credit card account is easier than an overdraft
The smart approach: Many businesses use both. A credit card for day-to-day expenses (paid off monthly within the interest-free period), and a business overdraft for larger cash flow gaps. This maximises the interest-free period benefit while having a significant facility available for larger needs.
The cost comparison over 3 months
To illustrate the difference: if you draw $50,000 for 90 days on a business overdraft versus carrying $50,000 on a business credit card at 18% p.a.:
- Business overdraft (at a typical non-bank rate): approximately $3,000–$4,500 in interest + service fees
- Business credit card at 18% p.a.: approximately $2,219 in interest - but minimum payments wouldn't have cleared the balance, so in practice the debt would persist longer
For amounts above $20,000 held for more than 2 months, an overdraft is almost always the cheaper option.

And if property security is the concern - facilities under $150,000 don't need it. See unsecured business overdraft.
Frequently asked questions
What's better, an overdraft or a credit card?
For amounts above $20,000 held longer than the interest-free period, a business overdraft is usually better - higher limits (up to $500,000), funds paid directly into your bank account, and interest charged only on the drawn balance. For small everyday expenses you can clear within 55 days, a credit card is often the better tool.
What is the difference between a credit card and an overdraft?
A business credit card is a payment tool with an interest-free period and rewards, but low limits and high ongoing rates. A business overdraft is a cash flow facility - you draw real funds up to your approved limit, pay interest only on what you use, and can cover wages, suppliers and ATO obligations that a card cannot pay.
When is a business credit card better than an overdraft?
When the amounts are small, you can repay in full within the interest-free period (up to 55 days), you want rewards points on everyday spending, or you need staff expense cards. Once a balance persists beyond the interest-free period at typical card rates of 15-23% p.a., an overdraft is almost always cheaper.
