The short version: most money advice treats credit as something to survive. That is half the picture. Credit is also the only way most South Africans will ever own a home, run a business or finish a qualification. The distinction that matters is not whether you borrow, but whether what you buy with the money is worth more over time than the interest costs you.
The one test
Ask what you are left holding when the debt is paid off.
A bond leaves you a house. A student loan leaves you a qualification that raises what you earn for forty years. Equipment finance leaves you a machine that produces income. In each case the debt bought something that outlasts it.
A holiday on a credit card leaves you the memory and the balance. Clothing on a store account leaves you clothes worth less than you paid and a monthly obligation. Neither is a moral failing, but neither is an investment, and calling them one is how people talk themselves into expensive habits.
The test is not about need. It is about what survives the repayment.
What that looks like in rands
Take a R900,000 bond over twenty years at 10.75%, against renting a similar place at R8,500 a month with rent rising 6% a year.
| Bond instalment | R9,137 a month |
| Paid over 20 years | R2,192,895, and you own the house |
| Rent over the same 20 years | R3,752,130, and you own nothing |
That is the case for borrowing, made honestly. The interest is real and large, and the bond still wins, because rent rises forever and a bond instalment does not, and because at the end one of them leaves you an asset.
The caveats are real too. That assumes you keep the house twenty years, that you can absorb rates, levies, insurance and maintenance on top of the instalment, and that a rate rise does not break you. Transfer costs mean a house sold after a few years often loses money. Borrowing well is not the same as borrowing early.
Three rules that separate the two kinds
The debt should not outlive the thing. Financing a car over 72 months when you will replace it at 60 means paying for something you no longer have. This is the most common way ordinary people end up permanently in debt without doing anything reckless.
The rate has to be beatable. A bond at 10.75% funds an asset that historically grows faster than that. A store card at 22% funds nothing that grows at all. Above roughly 15%, very little you can buy will outrun the interest.
It must survive a bad month. Good debt taken at the limit of what you can afford becomes bad debt the first time the rate rises or income dips. The instalment has to fit the worst month, not the best one.
Being financeable is itself the asset
Here is the part that gets missed. A good credit record is not a scoreboard. It is a cheaper price on every large thing you will ever buy, and the gap is bigger than most people’s savings rate.
Two percentage points on a R1 million bond is about R1,390 a month and roughly R333,000 over the term. Nobody saves their way to R333,000 on an ordinary salary. But a year of paying on time can move you between those bands, which makes the record one of the highest-return things you can work on, and it costs nothing but consistency.
That is what going from unfinanceable to financeable actually buys. Not approval. A permanently lower price.
The order that works
- Clear anything above 15% first. Paying off a 22% card is a guaranteed 22% return, which no investment can promise.
- Build a small buffer, so the next emergency does not go back onto the card you just cleared.
- Fix the record, six months before you need it rather than during the application.
- Then borrow, for something that outlasts the debt, at an instalment that fits a bad month.
Work through it with the affordability calculator and the credit health check. For the mechanics: secured and unsecured lending, what the score bands cost you, and why interest compounds against you as hard as for you.
How the figures were worked out: bond calculated on a standard amortising loan at 10.75% over 240 months, excluding rates, levies, insurance and maintenance. Rent projection assumes 6% annual escalation. Both are illustrative, not forecasts, and property values can fall as well as rise.
