Every registered credit provider in South Africa runs the same core test, because the National Credit Act requires it. Your gross income is verified, statutory deductions and a prescribed minimum for living expenses are subtracted, and your existing debt obligations as reported at the credit bureaus come off after that. Whatever survives is your discretionary income, and the proposed instalment has to fit inside it. Granting credit without that assessment is reckless lending, which is why an advertisement promising approval with no checks whatsoever is a sign you are dealing with someone operating outside the law rather than a lender with unusually generous criteria.
Where lenders genuinely differ
The affordability test is fixed, but the weight given to your history is not. Banks lean heavily on the bureau score and on how long you have held accounts. Microlenders and digital lenders lean on what your bank statements show right now: a salary arriving on the same date each month, debit orders that do not bounce, and a balance that is not scraped to zero by the tenth. This is why two applications submitted the same week can produce a decline from one lender and an approval from another. It is also why applying to a single lender and reading the outcome as a verdict on your creditworthiness is a mistake.
Why the easy option is the expensive one
Accessibility is priced. A lender that approves applicants others turn away absorbs more defaults, and the interest rate is where that cost lands. The National Credit Act caps how far this can go, and the ceilings differ by product: mortgages are capped lowest, credit facilities at the repo rate plus 14% a year, unsecured credit at the repo rate plus 21%, and short-term loans at 5% a month on a first loan. Read that last figure annually and the gap becomes obvious. The practical rule is to borrow the smallest amount that solves the actual problem, over the shortest term your budget absorbs, from the least expensive lender that will say yes.
What a decline actually means
A rejection is rarely a permanent judgement. Most declines come down to one of four things: the instalment did not fit your discretionary income, your bank statements did not show the income you declared, a listing on your bureau record was worse than you realised, or the documents were incomplete. Every one of those is fixable, and three of them can be fixed within a month. You are entitled to ask the lender for the reason in writing, and you should, because guessing wrong means the next application fails for the same cause.
