Typical limits run from R10,000 to R5 million (usually 1–3 times your average monthly turnover) at rates of Prime + 2%–5%. If you need faster approval, online lenders like Lula and Bridgement offer revolving credit facilities with decisions in 24–48 hours. This guide covers costs, requirements, bank comparisons, and the full application process.
Who This Is For
- Established businesses with consistent banking history

What is a Business Overdraft?
A business overdraft (or overdraft facility) is an agreement with your bank that allows your business account to go into negative balance up to a pre-approved limit. It's essentially a safety net that provides instant access to short-term credit whenever you need it.
Key Characteristics
- Revolving: Repay and draw again without reapplying
- On-demand: Access funds instantly via your account
- Interest on usage: Only pay for what you use
- Annual review: Typically renewed yearly
- Repayable on demand: Bank can technically call it in
How Business Overdrafts Work
Example Scenario
Your business has a R200,000 overdraft facility. Your account balance is R50,000. You need to pay suppliers R180,000.
- Day 1: Pay suppliers R180,000. Account balance: -R130,000
- Day 10: Customer pays R100,000. Account balance: -R30,000
- Day 15: More customers pay R80,000. Account balance: +R50,000
Interest is calculated daily on the negative balance and charged monthly. You only paid interest for the days you were overdrawn.

Bank reviews financials, cash flow, credit history, and risk profile. Takes 5-15 business days.

Pros and Cons

Best Practices for Using Overdrafts
- Use for short-term needs only: Overdrafts should fund timing gaps, not permanent working capital
- Clear to positive regularly: Banks want to see the account in credit at least once a month
- Don't max it out permanently: Using 100% limit constantly signals distress
- Keep good records: Helps at annual review time
- Communicate proactively: Tell your banker about expected changes before they happen

Frequently Asked Questions
What is the difference between a business overdraft and a loan?
An overdraft is a revolving credit facility linked to your business account—you draw and repay as needed, paying interest only on what you use. A term loan gives you a lump sum upfront with fixed monthly repayments over a set period. Overdrafts are better for short-term cash flow gaps; loans are better for specific purchases or investments.
How much overdraft can I get for my business in South Africa?
Overdraft limits typically range from R10,000 to R5 million for SMEs. Banks usually offer 1-3 months of average monthly turnover as an overdraft limit. For example, if your business turns over R200,000/month, you might qualify for R200,000-R600,000. Larger limits require security or strong financials.
What interest rate do business overdrafts charge in South Africa?
Most business overdrafts charge Prime + 2% to Prime + 5%, depending on your risk profile and relationship with the bank. As of January 2026, with Prime at 11.75%, this means effective rates of 13.75% to 16.75% per annum. Some banks offer Prime or Prime + 0% for low-risk, established businesses.
Do I need security for a business overdraft?
Smaller overdrafts (under R250,000) may be unsecured, relying on cash flow and business banking history. Larger facilities typically require security: property bonds, cession of debtors, sureties from directors, or fixed deposits. DFI-backed programmes like SEDFA offer some unsecured options for qualifying SMEs.
How do I apply for a business overdraft in South Africa?
Apply through your existing business bank — most South African banks (FNB, Standard Bank, ABSA, Nedbank) require 6–12 months of business banking history, at least 12 months of management accounts or audited financials, and proof of consistent revenue. The process takes 5–15 business days. Online lenders like Lula and Bridgement offer revolving credit facilities that work similarly to overdrafts with faster approval (24–48 hours) for qualifying businesses.
What is the difference between a business overdraft and a business term loan?
An overdraft is a revolving credit facility — you draw and repay repeatedly up to your limit, paying interest only on what you use. A business term loan gives you a lump sum upfront with fixed monthly repayments over a set period (typically 12–60 months). Overdrafts suit recurring short-term cash flow gaps; term loans suit specific investments where you know the amount upfront.
