In short
The honest answer to "which car can I afford?" is usually a smaller one than the finance house will approve. A lender is required to establish that you can service the instalment; it does not ask whether the car will still make sense in year four, when the service plan has run out and the tyres need replacing. Those are two different questions, and only the second one keeps you out of trouble.
As a working rule, keep the finance instalment near 12% of your gross monthly salary, and keep everything the car costs - instalment, comprehensive insurance, fuel, servicing, tyres and the licence renewal - under roughly a quarter of it. On R20 000 a month that points to an instalment of about R2 400, which finances a car of roughly R105 000 over five years. On R40 000 it points to R4 800 a month and a car around R211 000. Those figures are deliberately lower than the ones a dealership will put in front of you.
Below are the salary bands and what they realistically buy, the arithmetic behind them, the ownership costs that never appear on a quotation, and the two structures - a long term and a balloon payment - that make an unaffordable car look affordable on paper.
What your salary buys
Each band below takes 12% of gross monthly income as the instalment ceiling and converts it into a purchase price at 13% a year over 60 months, with no deposit and no balloon payment. Treat the price as the top of your range, not the target.
Rates in South Africa are quoted as prime plus a margin, so your own figure depends on your credit record, the deposit and the age of the car. The prices exclude the initiation fee, the monthly service fee and compulsory comprehensive insurance. Ask for a pre-agreement quotation and a full repayment schedule before you sign - under the National Credit Act you are entitled to both.
The arithmetic
A lender and a sensible buyer answer different questions. Under the National Credit Act, a credit provider registered with the National Credit Regulator must run an affordability assessment before it may grant vehicle finance: it takes your gross income, deducts statutory deductions, existing credit repayments and your declared living costs, and checks that the instalment fits into what is left. Pass that test and the finance is approved - even if the car swallows every spare rand you have.
Your own test should be tighter. Start with 12% of gross monthly salary as the instalment ceiling, then convert it into a price at the rate you are likely to be offered. At 13% a year over 60 months, every R1 000 of monthly instalment finances about R44 000 of car. So R3 000 a month is roughly R132 000, and R5 000 a month is roughly R220 000. Change the rate and the whole ladder shifts.
Then run the second check. Add comprehensive insurance, fuel, servicing, tyres and the annual licence renewal, and keep the all-in figure under about a quarter of your gross salary. If it does not fit, the answer is not a longer term - it is a cheaper car.
Practical moves
None of these require earning more. Each one changes the amount you finance, the rate you pay or the length of the agreement - and each is worth tens of thousands of rand at the top of your range.
Decide what you can pay every month first, then let that number decide which cars you are allowed to look at.
Walking onto a dealership floor with a model in mind reverses the process and almost always ends in a longer term. Work the instalment out at your kitchen table, convert it into a price, and treat that price as a hard ceiling rather than an opening position in a negotiation.
A deposit cuts the amount financed, the instalment and the interest, and it keeps you out of negative equity.
On a R200 000 car, R40 000 down moves the instalment from about R4 550 to R3 640 at 13% over 60 months and saves roughly R14 600 in interest. It also keeps the outstanding balance below the resale value in the early years, which matters if the car is written off or you need to sell.
Every extra year lowers the instalment a little and raises the total cost of the car by a lot.
R200 000 at 13% costs about R4 550 a month over 60 months and R4 015 over 72. The instalment drops by R535, but you pay roughly R16 000 more in total and spend another year owing money on a vehicle that has carried on depreciating the whole time.
The lump sum parked at the end is still yours to settle, and it attracts interest for the whole term.
A 20% balloon on R200 000 trims the instalment to about R4 075, but R40 000 falls due in month 60. Most buyers then refinance it, which restarts interest on a five-year-old car, or trade in and roll the shortfall into the next agreement - which is how permanent vehicle debt starts.
Comprehensive cover is compulsory on financed cars and can add anywhere from R800 to R2 500 a month.
The premium depends on the model, your age, your claims history and where the car is parked overnight, and two cars at the same price can differ by R700 a month. Ask for quotes on your whole shortlist before you commit, not after you have taken delivery of the vehicle.
Your bureau record sets the rate you are offered, and the rate quietly sets the car you can afford.
You are entitled to one free credit report a year from each registered bureau, so pull yours and dispute anything wrong. Two percentage points of rate on the same R4 500 instalment is worth roughly R9 000 of car, and a clean record is what gets you approved without a large deposit.
Every existing repayment is deducted from your affordability before the car instalment is even taken into account.
A R700 store account cleared is R700 of instalment released, which is around R31 000 more car at 13% over 60 months. Close the account as well as paying it off, so the available limit stops counting against you in the assessment the lender runs on your file.
Letting the first owner absorb the steepest depreciation is the cheapest saving available to a car buyer.
New cars commonly lose 20% to 30% of their value in the first year and about half over five. A two-year-old model with service history and some factory warranty remaining often costs a third less than new, which moves you a whole segment up for exactly the same monthly instalment.
Affordability rules of thumb are useful only when the arithmetic behind them is shown. Jacob has recalculated the salary-to-vehicle examples in this article.
Beyond the instalment
A finance quotation shows the instalment, the initiation fee and the monthly service fee. It says nothing about the costs that actually decide whether the car is affordable, and those are rarely smaller than half the instalment itself.
Comprehensive cover is a condition of every vehicle finance agreement in South Africa and stays compulsory for the full term. Depending on the car, your age, your area and where it sleeps at night, expect R800 to R2 500 a month. Fuel comes next: a small hatchback covering 1 000 km a month at around seven litres per 100 km burns close to R1 500 at current pump prices. Then add a service once the plan expires, a set of tyres every three to four years, and the annual licence renewal. On a R160 000 car, R2 500 to R3 500 a month on top of the instalment is a realistic planning figure.
Depreciation never shows up as a monthly debit, which makes it easy to ignore, but it is usually the single largest cost of owning a new car. A R300 000 vehicle that loses 30% in its first year has cost you R90 000 before a cent of interest. Finance the full price over 72 months and you will owe more than the car is worth for the first two to three years. If it is stolen or written off in that window, the insurer pays market value and you are left owing the difference - which is why shortfall cover exists, and why a deposit is worth more than it looks.
Buy less car, put down more, or wait another six months. Stretching the term until the instalment fits is the one adjustment that feels like a solution and is not.
Questions and answers
Straight answers to the questions that come up most often when working out what car a salary will actually carry.
Keep the finance instalment near 12% of gross monthly income, and everything the car costs - instalment, insurance, fuel, servicing and licensing - under roughly a quarter of it. The stricter 20/4/10 rule many advisers use caps all vehicle costs at 10% of gross, with 20% down and a maximum four-year term.
About R2 400 a month for the instalment, which finances a car of roughly R105 000 over 60 months at 13% a year. That is a good used hatchback rather than anything new. A R20 000 deposit lifts the ceiling to around R125 000 without changing the monthly figure.
If the affordability assessment passes, yes, but the sums are tight. R1 200 a month finances about R50 000, and insurance plus fuel on even a small car adds R1 500 or more. Many buyers in this band are better off saving for a cash car or sharing transport for another year.
The assessment starts with gross income, then deducts tax and statutory deductions, existing credit repayments and your declared living expenses. Your bank statements are the evidence, so expense figures that do not match what actually leaves your account will simply be replaced with realistic ones.
Nothing is legally required and 100% finance is widely available, but 10% to 20% down improves your rate, cuts the instalment and keeps you out of negative equity. On a R200 000 car, 20% down saves roughly R14 600 in interest across five years.
Only if you have a concrete plan to settle the lump sum in cash. It lowers the instalment by parking part of the debt at the end, where it keeps attracting interest. Refinancing a balloon on a five-year-old car is how buyers end up in a cycle of permanent vehicle debt.
Vehicle finance is secured by the car, so it usually carries the lower rate and the longer term. A personal loan costs more but leaves you owning the vehicle outright from day one, which suits an older car or a private sale that a finance house will not fund.
