Take an applicant earning R21 000 gross. After PAYE, UIF and a pension contribution, R17 000 lands in the account. Declared living expenses come to R8 500, and an existing vehicle instalment takes R2 500. Discretionary income is therefore R6 000. A lender working to a conservative ceiling might allow an instalment of around R3 400, keeping total credit repayments comfortably inside a third of gross income.
At roughly 24% a year over sixty months, R3 400 a month supports a little over R118 000 of capital before costs. The monthly service fee and credit life cover come out of the same instalment, so the realistic loan is closer to R100 000. Price the same applicant at 18% because of a strong credit record and the figure rises past R120 000; price them near the legal ceiling and it falls below R90 000. The instalment did not move at all.
Why the maximum is rarely the right answer
The amount you qualify for and the amount you should take are different numbers, and the gap between them is where most personal loans go wrong. Affordability assessments work on the month you are having now, with the salary you have now and no unexpected expenses. They do not model a retrenchment, a medical emergency or an interest rate cycle. Borrowing to your ceiling leaves nothing between you and the first month that does not go to plan, and a missed instalment is reported to the bureaus and stays on your record for years.
A better approach is to work backwards. Write down what the money is genuinely for, to the rand rather than to a round number. Work out the instalment that fits your budget with room to spare, not the instalment the lender will allow. Then take the shortest term that instalment supports, because the term drives the total cost more than the headline rate does. If the loan you need does not fit inside that instalment, the honest conclusion is usually that the timing is wrong rather than that the term should be longer.
When a personal loan is the wrong instrument
Unsecured credit is priced for the risk the lender carries, so if the purpose allows a secured alternative, compare it first. Vehicle finance against the car itself, an access facility on an existing bond or a further advance against property all price well below an unsecured personal loan for the same amount. The reverse is also true: if the alternative on the table is short-term credit at up to 5% a month, a personal loan at annual pricing is the cheaper instrument by a wide margin. What matters is matching the product to the purpose and the term to the life of whatever you are buying.
