How Much Can I Borrow in South Africa? — NCA Affordability Guide
Last updated: June 2026 · Affiliate disclosure
Before applying for any loan, know exactly how much you can borrow. South African lenders use a standardised NCA affordability assessment — this guide shows you how to calculate it yourself.
The NCA Affordability Formula
The calculation every lender uses:
| Step 1: Net monthly income (take-home after tax and deductions) | + R[your income] |
| Step 2: Minus all existing monthly debt repayments | - R[existing debt] |
| Step 3: Minus estimated monthly living expenses | - R[living costs] |
| = Disposable income available for new debt | = R[available] |
| Step 4: Max new repayment ≈ 30-40% of disposable income | × 0.35 |
Worked Example
| Item | Amount | Notes |
|---|---|---|
| Net monthly salary | +R18,000 | After tax, pension, medical aid |
| Existing vehicle finance | -R3,200 | Monthly instalment |
| Credit card minimum | -R800 | Minimum payment |
| Estimated living expenses | -R8,000 | Rent, food, transport, utilities |
| Disposable income | = R6,000 | |
| Max new repayment (35%) | = R2,100/month | This is your borrowing ceiling |

What Happens If You Borrow Too Much
The NCA defines over-indebtedness as when your net income minus living expenses is insufficient to meet your minimum monthly obligations. If you reach this point:
- Lenders are legally required to decline your application
- You can apply for debt review which restructures all payments and provides legal protection
- Continuing to miss payments leads to defaults, judgments, and garnishee orders

How much can I borrow on a personal loan in SA?
Calculate your disposable income (net income minus existing debt and living costs), then multiply by 30–40%. That's your maximum monthly repayment. Use our table above or the loan calculator to convert that to a loan amount.
What is the debt-to-income limit?
No NCA-mandated fixed limit, but the practical ceiling most lenders apply is 40% of net income for total debt repayments. Above this you are likely considered over-indebted.
Can I increase my borrowing limit?
Yes — by increasing income, reducing existing debt obligations, or extending the loan term to lower the monthly repayment. Improving your credit score also increases what lenders are willing to offer.
What is over-indebted under the NCA?
When your net income minus living expenses is insufficient to meet your minimum monthly debt obligations. If over-indebted, debt review provides a formal legal solution.
