Most people applying for a loan think the income verification is where the lender’s scrutiny is focused. The salary, the payslip, the bank deposits. But there is a second half of the affordability equation that gets less attention and causes more surprises: the expense assessment. Lenders are not just checking what comes in. They are checking what goes out — and how much of what goes out is genuinely non-negotiable.
This article explains exactly how South African lenders assess monthly expenses during an affordability check — what they look for, what methods they use, how they decide which expenses count, and what you can do to present your expense profile in the most accurate and application-friendly way possible.
Why Expense Assessment Matters
The NCA requires every registered lender to conduct an affordability assessment that accounts for the applicant’s ‘existing financial means and prospects,’ their ‘financial obligations,’ and their ‘living expenses.’ That last category — living expenses — is the one that requires judgment: it cannot be read directly off a payslip or a credit bureau report. It has to be estimated, declared, or extracted from transaction data.
Different lenders handle this differently, which is one reason why two lenders can reach different qualifying amounts from the same application. The expense assessment methodology matters — and understanding it lets you approach it strategically.
The Three Methods Lenders Use
Method 1: Declared Expenses (Application Form)
The most common approach, especially at mid-market and specialist lenders. The application form asks you to declare your monthly expenses across categories — rent, food, transport, medical, schooling, utilities. The lender uses your declared figures in the NDI calculation.
This method relies on honest declaration. Understating expenses to produce a larger qualifying amount is both dishonest and counterproductive — a loan approved on understated expenses may be unaffordable in practice, leading to exactly the missed payments the affordability assessment is designed to prevent.
Method 2: Minimum Living Expense Tables
Some lenders supplement or replace declared expenses with standardised minimum living expense tables — reference amounts derived from Stats SA data and updated periodically. The table provides a minimum floor for expenses by household size and income band.
For example, a single person earning R10,000 per month might have a minimum living expense floor of R3,200 for food, transport, and basic utilities. If your declared expenses are below this floor, the lender uses the table minimum instead. If your declared expenses are above the floor, your declared figure applies.
| Expense Category | Typically Declared | Lender Minimum Floor (approx.) | What Applies |
| Rent or bond payment | Exact amount from lease/bond | No floor — actual amount used | Your declared figure |
| Food and groceries | R800–R2,500 | R600–R1,200 (single person) | Higher of declared or floor |
| Transport (public/fuel) | R400–R1,500 | R400–R800 | Higher of declared or floor |
| Utilities (electricity, water) | R300–R800 | R200–R500 | Higher of declared or floor |
| Airtime and data | R100–R400 | R100–R250 | Higher of declared or floor |
| School fees (if applicable) | Actual amount | No floor — actual amount used | Your declared figure |
| Medical expenses (out of pocket) | R0–R800 | Included in broader living estimate | Higher of declared or floor |

Method 3: Bank Statement Extraction
The most thorough approach, increasingly used by mainstream banks and large online lenders: automated analysis of bank statement transactions that categorises every outflow into expense types. The software reads three to six months of statements and produces a spend-by-category summary.
This method generates an actual expense figure rather than a declared or estimated one. It is more accurate — and it can surface spending patterns that reveal financial strain, such as regular gambling transactions, frequent overdraft usage, or a pattern of end-of-month near-zero balances.
If your bank statement shows end-of-month balances consistently close to zero, or regular overdraft usage to cover the final week before salary, this tells the lender that your current income barely covers your current obligations — before any new loan instalment is added. It is one of the clearest signals of affordability strain available to the automated assessment system.
What Expenses Count — and What Does Not
| Expense Type | Counted? | How Lenders Handle It |
| Rent or bond payment | Yes — fully | Deducted in full; exact figure from declaration or statement |
| Food and groceries | Yes | Deducted at declared or floor amount — whichever is higher |
| Transport (commuting) | Yes | Deducted — fuel, taxi fare, or public transport |
| Medical aid contributions (on payslip) | Yes | Subtracted as a payslip deduction before NDI |
| Private school fees | Yes — if declared | Full amount deducted; material impact on NDI |
| Streaming subscriptions (Netflix, etc.) | Partially | Extracted from bank statements; small but counted |
| Gambling transactions | Not an expense — a flag | Signals financial risk; affects assessment negatively |
| Luxury or discretionary spending | Partially — context-dependent | High discretionary spend may reduce qualifying amount |
| Informal support payments (family) | Only if declared | Not visible in bank statements unless EFT; declare if significant |
| Loan instalments (existing credit) | Yes — in full | Subtracted as obligations, not living expenses, in NDI calculation |

How to Present Your Expenses for the Best Application Result
Presenting your expenses accurately and strategically does not mean understating them — it means ensuring the picture the lender sees is complete, clean, and reflects your genuine financial management:
- Declare rent accurately. Rent is the single largest living expense for most South Africans and has the biggest impact on NDI. Declare the actual amount — not a rounded estimate, not a figure from six months ago. Use the current lease agreement amount.
- Clean up bank statement spending patterns before applying. Three to six months of bank statements are submitted. If the most recent month shows improved financial discipline relative to earlier months, the improvement is visible. Reducing unnecessary subscriptions, avoiding overdraft usage, and maintaining a positive end-of-month balance for two to three months before applying produces a cleaner expense picture.
- Declare support payments you make to family members. Many South Africans informally support extended family — sending money home, paying a parent’s utilities, covering a sibling’s school fees. If these payments are real and regular, they should be declared. Not declaring them and having the lender see the bank transfers anyway creates an inconsistency.
- Do not understate expenses in the hope of qualifying for more. A loan approved on understated expenses creates an instalment that your real budget cannot support. The affordability check is meant to protect you — gaming it defeats its purpose and creates the financial hardship it was designed to prevent.
Frequently Asked Questions
1. How do I know which expense assessment method my lender will use?
Most lenders disclose their assessment approach in the application process, particularly regarding bank statements. If the application requests three months of bank statements alongside the application form, the lender is likely using a combination of declared expenses and bank statement verification. If only a payslip and ID are required, declared expenses alone are more likely. For larger loan amounts at mainstream banks, automated statement analysis is increasingly standard.
2. If I declare lower expenses, will I qualify for a larger loan?
Possibly in the short term — but this is not advisable and can constitute a fraudulent misrepresentation on a credit application. More practically: if your declared expenses are below the lender’s minimum floor table, the higher floor figure is used regardless of your declaration. And if the bank statement analysis reveals actual spending significantly above declared amounts, the bank statement figure may override the declaration. Accurate declarations produce the most predictable outcome.
3. Does my entertainment spending affect my loan approval?
It can — if it is large enough to be visible in the bank statement analysis and if it materially reduces the end-of-month balance. Automated statement analysis categorises entertainment and discretionary spending separately from essential living costs. A borrower who spends R3,000 per month on entertainment on a R10,000 salary is presenting a different financial management picture from one who spends R400. Very high discretionary spend can cause some lenders to apply a conservative expense estimate that reduces the qualifying amount.
4. What if my living expenses genuinely are very high — will I be declined?
High living expenses are not a reason for decline — they simply reduce the NDI available for loan servicing. If your living expenses are genuinely high (large family, high rent, private school fees) and your income is moderate, the honest affordability assessment will produce a low qualifying amount or a decline. This is the assessment working correctly — a loan whose instalment cannot fit within the real NDI after real expenses is a loan that would create hardship. If the qualifying amount is lower than the need requires, the practical options are to apply for less, reduce expenses where possible, or grow income before reapplying.
5. Do lenders look at how I spend money on luxuries?
Mainstream banks using automated statement analysis do categorise spending — including discretionary spending on restaurants, entertainment, luxury retail, and gambling. This information is used contextually rather than as a binary pass/fail: a borrower with moderate discretionary spending and a positive end-of-month balance is assessed differently from one with high discretionary spending and an overdraft at the end of every month. The pattern of financial management — not any individual transaction — is what the statement analysis is looking for.
Final Thought
The expense assessment is the part of the affordability check that most applicants have the most control over — not by manipulating the figures, but by genuinely managing the financial behaviour that the bank statement reflects. Three months of clean, well-managed statements where income clearly exceeds outflows and a positive balance is maintained throughout tells a powerful story about financial management capacity. That story is exactly what lenders are reading when they pull those statements. Write it deliberately.
