What is an affordability assessment? An affordability assessment is a mandatory evaluation that every NCR-registered credit provider in South Africa must perform before granting a loan or credit facility. Required by the National Credit Act (NCA), it involves verifying your gross income, deducting your existing financial obligations — including tax, living expenses, and debt repayments — and determining whether you have enough discretionary income to comfortably afford the proposed repayments. The purpose is to prevent reckless lending and protect consumers from taking on more debt than they can manage.
If you have ever been declined for a personal loan and wondered why, the answer almost certainly lies in the affordability assessment. Even if your credit score is good, a lender will not approve your application if the numbers show you cannot afford the repayments. Understanding how this process works — and what you can do to improve your results — gives you a significant advantage when applying for credit.
This guide explains the affordability assessment process in detail, shows you how to calculate your own debt-to-income ratio, and provides practical tips to improve your chances of approval. All information is based on the requirements of the National Credit Act and current South African lending practices.
What Is an Affordability Assessment Under the NCA?
The affordability assessment was introduced as a core requirement of the National Credit Act (NCA), specifically under the Affordability Assessment Regulations published in 2014. These regulations were designed to address the growing problem of over-indebtedness among South African consumers and to prevent credit providers from engaging in reckless lending.
Under the NCA, a credit provider must not enter into a credit agreement with a consumer if the assessment shows that the consumer will not be able to satisfy the obligations under the agreement in a timely manner. This is not a suggestion — it is a legal obligation. A lender that approves credit without conducting a proper affordability assessment is engaging in reckless lending, which is an offence under the NCA.
The assessment must consider, at a minimum:
- Gross income — Your total income before deductions, verified through payslips, bank statements, or tax returns.
- Statutory deductions — Tax (PAYE), UIF, and any other mandatory deductions from your salary.
- Necessary expenses — Living expenses such as housing, food, transport, utilities, education, medical aid, and insurance.
- Existing debt obligations — All current loan repayments, credit card minimums, store account payments, and other financial commitments.
- Discretionary income — The amount left over after all deductions and obligations. This is what determines whether you can afford the new loan repayment.
The assessment is not a one-size-fits-all calculation. Different lenders use different expense models — some use declared expenses, others use statistical models based on income bands, and some use a combination. However, all must comply with the minimum standards set by the NCA regulations.
What Lenders Look At — Income, Expenses, Existing Debts & DTI Ratio
When you apply for a loan, the lender will examine four key areas to determine your affordability. Understanding each of these components helps you prepare and present the strongest possible application.
1. Income Verification
The lender must verify your income — they cannot simply take your word for it. For salaried employees, this typically means providing your latest 3 months' payslips and 3 months' bank statements. The bank statements confirm that the salary reflected on your payslip is actually being deposited into your account. For self-employed applicants or those with irregular income, lenders usually require 6 months' bank statements and may request tax returns or financial statements.
Lenders look at your net income (take-home pay after tax and statutory deductions) rather than your gross salary. If you have multiple sources of income — such as a side business, rental income, or commission — you may be able to include these, but you will need to provide documentary evidence for each.
2. Living Expenses
Lenders must account for your basic living expenses. The NCA regulations set minimum expense norms based on income bands — even if you declare lower expenses, the lender must use the prescribed minimum. These expenses include:
- Housing — Rent or bond repayments (if not already captured as a debt obligation)
- Food and groceries — Monthly household food costs
- Transport — Fuel, public transport, vehicle maintenance
- Utilities — Electricity, water, rates, refuse removal
- Education — School fees, university tuition, study material
- Medical — Medical aid contributions, out-of-pocket medical costs
- Insurance — Life insurance, short-term insurance premiums
- Communication — Cellphone, internet, DSTV or streaming services
- Maintenance — Child support or maintenance obligations
3. Existing Debt Obligations
The lender will pull your credit report from one or more credit bureaus to identify all your existing credit accounts. This includes home loans, vehicle finance, personal loans, credit cards (minimum payment or actual payment), store accounts, cellphone contracts, and any other instalment agreements. The total of these monthly obligations is a critical input into the affordability calculation.
This is one reason why it is important to check your credit report before applying — if there are accounts listed that you have already paid off but that have not been updated, they will inflate your debt figure and reduce your apparent affordability.
4. Debt-to-Income (DTI) Ratio
The DTI ratio is the percentage of your net monthly income that goes towards servicing debt. It is one of the most important metrics lenders use. A lower DTI ratio indicates that you have more room to take on new debt, while a high DTI ratio suggests you are already stretched thin. We cover how to calculate your DTI ratio in detail in the next section.
How to Calculate Your Debt-to-Income Ratio — Formula & Example
Your debt-to-income (DTI) ratio is a straightforward calculation that any consumer can perform at home before applying for a loan. Knowing your DTI before you apply helps you understand your chances and avoid unnecessary declined applications (which generate hard enquiries on your credit report).
The formula:
DTI Ratio = (Total Monthly Debt Payments / Net Monthly Income) x 100
Example: Let us say you earn a net monthly income (after tax) of R25,000. Your monthly debt obligations are:
| Debt Obligation | Monthly Payment |
|---|---|
| Vehicle finance | R4,500 |
| Credit card minimum | R1,200 |
| Store account (Woolworths) | R600 |
| Cellphone contract | R700 |
| Personal loan | R1,500 |
| Total monthly debt | R8,500 |
DTI Ratio = (R8,500 / R25,000) x 100 = 34%
A DTI of 34% means that 34% of your net income goes towards servicing debt. This leaves 66% for living expenses and any new credit obligations. Whether this is sufficient depends on the lender's thresholds and the size of the loan you are requesting.
Now let us say you want to apply for a personal loan with a monthly repayment of R2,000. Your new DTI would be:
New DTI = ((R8,500 + R2,000) / R25,000) x 100 = 42%
At 42%, some lenders may approve you, but others will decline. Understanding this before you apply allows you to either reduce existing debt first or apply for a smaller amount.
What DTI Ratio Do You Need to Get Approved?
Different loan products have different DTI thresholds. The table below provides general guidelines based on South African lending practice. Individual lenders may have stricter or more lenient criteria, but these represent typical industry benchmarks:
| Loan Type | Typical Max DTI | Notes |
|---|---|---|
| Home loan (mortgage) | 30% | Banks are strict. Most require DTI below 30%, including the proposed bond repayment. Some may stretch to 33% for higher-income applicants. |
| Vehicle finance | 35% | Slightly more flexible than home loans. A deposit of 10–20% can offset a higher DTI. |
| Personal loan | 40% | Most mainstream lenders cap at 40%. Specialist lenders may accept up to 45–50% at higher interest rates. |
| Credit card | 40% | Banks assess DTI based on the minimum payment obligation, not the full credit limit. |
| Payday / short-term loan | 50–60% | Higher DTI accepted because loan terms are short (1–6 months) and amounts are smaller. Higher interest rates apply. |
| Debt consolidation loan | 45–50% | Consolidation lenders accept higher DTI because the purpose is to reduce it. They assess post-consolidation DTI rather than current. |
Key insight: Your DTI is not the only factor. Even if your DTI is within the acceptable range, a lender may still decline your application based on your credit score, employment stability, or other risk factors. Conversely, a lender may approve a slightly higher DTI if you have an excellent credit score, a long employment history, and a strong banking record.

How to Improve Your Chances of Passing — 6 Tips
If you are concerned about passing the affordability assessment, there are concrete steps you can take before applying to strengthen your position. Lenders assess your financial situation at the moment of application, so changes you make in the weeks and months before can make a meaningful difference.
- 1. Pay down existing debt. The most effective way to improve your affordability is to reduce your existing debt obligations. Focus on paying off the smallest debts first (the "snowball method") to eliminate monthly payments entirely. Even paying off a single R500/month store account reduces your DTI and frees up affordability for a new loan. If you have multiple debts, consider a debt consolidation loan to reduce your total monthly obligation.
- 2. Close unused credit facilities. Open credit accounts — even if they have a zero balance — can count against you. Some lenders include the potential monthly repayment on available credit limits (e.g. 3–5% of your total credit card limit) when calculating your obligations. Closing unused store accounts and credit cards can reduce your calculated debt load and improve your affordability.
- 3. Increase your income. If reducing expenses is not sufficient, look for ways to increase your income. This could include overtime, a part-time job, freelance work, or rental income. The key is that the income must be verifiable — if it does not appear on your bank statements or payslips, the lender cannot include it in the assessment. Start building a paper trail at least 3 months before your application.
- 4. Reduce your declared expenses. While lenders apply minimum expense norms, you do have some control over discretionary expenses. Review your bank statements for unnecessary subscriptions, excessive entertainment spending, or high cellphone contract costs. Reducing these before applying can improve your net discretionary income. Note: do not under-declare expenses, as lenders verify against your bank statements and may decline dishonest applications.
- 5. Apply for the right amount. Many consumers are declined because they apply for more than they can afford, not because they cannot get any credit at all. Calculate your DTI first, determine how much additional monthly repayment you can afford, and then apply for a loan amount that fits within that payment. Applying for R3,000 and being approved is better than applying for R8,000 and being declined.
- 6. Clean up your credit report. Check your credit report for errors before applying. Paid-up accounts that still show as outstanding will inflate your debt figure. Accounts that are not yours may be adding to your obligations. Dispute any errors and wait for them to be corrected before submitting your loan application.

What Happens If You Fail the Affordability Assessment?
Failing the affordability assessment means the lender has determined that you do not have sufficient discretionary income to comfortably afford the loan repayments. Under the NCA, the lender is legally prohibited from approving your application in this case. Lending to someone who cannot afford the repayments constitutes reckless lending, which can result in the credit agreement being declared void by a court.
If you are declined, here is what you should know:
- You have the right to know why. The lender must provide you with a reason for the decline. This is your right under the NCA. Ask specifically what factor caused the decline — was it your DTI ratio, your credit score, income verification issues, or something else? This information helps you address the problem before trying again.
- A decline does not mean "never." Your affordability is assessed at the time of application. If you reduce your debts, increase your income, or correct errors on your credit report, you may pass the assessment when you reapply in the future. However, avoid reapplying immediately — each application generates a hard enquiry on your credit report, and multiple enquiries in a short period can lower your credit score.
- Consider a smaller loan amount. If you were declined for R8,000, you may be approved for R3,000 or R4,000. Ask the lender if there is a loan amount that would fall within your affordability. Some lenders will offer you a reduced amount rather than a flat decline.
- Do not turn to unregistered lenders. Being declined by NCR-registered lenders does not mean you should borrow from unregistered "loan sharks." Unregistered lenders do not conduct affordability assessments, charge illegal interest rates, and often use intimidation to collect. These loans will make your financial situation worse, not better. If you are struggling financially, contact a registered debt counsellor or the National Credit Regulator for advice.
- Explore debt consolidation. If your existing debts are the primary reason for the failed assessment, a debt consolidation loan may help. By combining multiple debts into a single loan with a lower overall monthly payment, you can reduce your DTI ratio and free up affordability for future credit needs.
The affordability assessment exists to protect you. While it can be frustrating to be declined, the assessment prevents you from taking on debt that could lead to default, judgment, or debt review — outcomes that are far worse than a temporary decline. Use the experience as a financial health check and take steps to improve your position before reapplying.

Frequently Asked Questions
An affordability assessment is a mandatory evaluation that all NCR-registered credit providers must perform before granting credit. Required by the National Credit Act (NCA), it involves verifying your gross income, deducting your existing financial obligations, and determining whether you have sufficient discretionary income to comfortably afford the proposed loan repayments. The purpose is to prevent reckless lending and protect consumers from over-indebtedness.
Most South African lenders prefer a DTI ratio below 40% for personal loans, though some will consider applications up to 50%. For home loans, banks typically require a DTI below 30%. Short-term and payday lenders may accept higher DTI ratios (up to 50–60%) but charge higher interest rates. The lower your DTI ratio, the better your chances of approval and the more favourable your interest rate.
For an affordability assessment, you will typically need: your South African ID document, your latest 3 months' payslips (or 6 months' bank statements if self-employed), 3 months' bank statements showing income and expenses, proof of residence, and details of all existing debts and financial obligations. Some lenders may also request employer contact details for verification purposes.
If you fail the affordability assessment, the lender is legally prohibited from granting you the loan under the NCA. Your options include: applying for a smaller loan amount, reducing your existing debts to lower your DTI ratio, increasing your income, considering debt consolidation, or trying a different lender with different assessment criteria. Avoid reapplying immediately, as each application generates a hard enquiry on your credit report.
