Put a R15,000 fridge and washing machine on a credit card and pay only the minimum each month, and the debt can follow you for close to two decades. Borrow the same amount as a two-year personal loan and it is gone in 24 instalments, even though the loan’s interest rate may well be higher. That contrast is the heart of the credit card vs personal loan question. The cheaper product on paper is not always the cheaper product in your hands, because so much depends on how you repay.
Both are unsecured credit, both are regulated by the National Credit Act, and both need an affordability assessment before a lender says yes. The differences lie in how the interest is capped, how repayments are structured and how easy it is to keep borrowing.
How each one is built
A personal loan is a fixed amount paid into your account in one go. You repay it in equal monthly instalments over an agreed term, often somewhere between six months and six years. When the last instalment goes off, the account closes. If you want more money, you have to apply again.
A credit card is a credit facility. The bank gives you a limit, you spend against it, and each month you can repay the full balance or anything down to the minimum payment. Whatever you repay becomes available to spend again. There is no end date unless you close the account.
That single design difference drives most of what follows. A loan puts the repayment plan in the contract. A card leaves the plan up to you.
What the law lets each one charge
The National Credit Regulations set separate ceilings for the two products. With the repo rate at 7.25%, the caps currently work out as follows:
- Credit facilities, including credit cards: repo rate plus 14% a year, which is 21.25%.
- Unsecured loans, including most personal loans: repo rate plus 21% a year, which is 28.25%.
These are maximums. Banks price each customer individually, so someone with a strong credit record may be offered either product well below the cap. Standard Bank, for example, says its credit card rates range from prime minus 0.25% up to the legal maximum depending on the customer. The point is that, for the same borrower, a card is allowed to charge less interest than a personal loan.
Fees work a little differently. Both products can carry an initiation fee and a monthly service fee of up to R60 plus VAT. On a personal loan the initiation fee is usually tied to the amount borrowed and can reach R1,050 plus VAT. Card issuers often charge a smaller once-off fee when the card is opened, and the monthly card fee depends heavily on the card tier and any bundled bank account. Check the fee schedule rather than assuming.
The interest-free period, and where it stops
The feature that gives credit cards their reputation is the interest-free period. Many South African cards offer up to 55 days without interest on purchases, provided you pay the full closing balance by the due date. Use a card this way and you are borrowing for free for a few weeks.
Three things break that arrangement:
- Paying anything less than the full balance. Interest is then charged on what you carry over.
- Cash withdrawals. Interest usually starts on the day you draw the cash, and a withdrawal fee is added on top.
- Purchases moved to a budget facility. Spreading a purchase over 12 or 24 months on the card turns it into interest-bearing debt from the start.
A personal loan has no interest-free period at all. Interest runs from the day the money is paid out.
The minimum payment problem
Card statements show a minimum payment, often around 3% of the balance. It is set low on purpose, so that a tight month does not push you into arrears. The trouble starts when the minimum becomes the plan.
Here is a hypothetical case that shows the effect. A R15,000 card balance at the 21.25% cap, with no further spending, repaid at 3% of the balance each month (and at least R50 once the balance gets small), would take roughly 19 years to clear. The interest over that time comes to about R20,000, more than the original purchases. Because the payment shrinks as the balance shrinks, most of each early payment goes to interest.
Now take the same balance and pay a fixed R450 a month, which is what the first minimum payment would have been. The debt is cleared in a little over four years and the interest falls to roughly R7,900. Pay it down over two years, at about R773 a month, and interest drops to around R3,540. Same card, same rate, three very different outcomes. Fees are left out of all three figures.
For comparison, a R15,000 personal loan over 24 months at the 28.25% cap costs about R825 a month and roughly R4,800 in interest, again before fees. The loan is more expensive than the card repaid on the same schedule, but far cheaper than the card repaid at the minimum. That is why the honest answer to which is cheaper starts with another question: how will you actually repay it?
Our guide to revolving credit looks at the same re-borrowing risk on revolving loans, which work in a similar way to cards.
When a credit card tends to make more sense
A card usually fits better when:
- the expense can be cleared within the interest-free period or within a few months
- you need a buffer for irregular costs, such as car services or school trips, rather than a lump sum
- you already have a card with a reasonable rate and unused limit, so there is no new initiation fee
- you are disciplined about paying more than the minimum and do not use the card for day-to-day spending you cannot cover
Cards also offer some practical protections. Many issuers will help dispute a purchase where goods are not delivered, and some include travel or purchase insurance. Those features vary by card, so read the terms rather than relying on them.
When a personal loan tends to make more sense
A personal loan is often the better tool when:
- the amount is large and will take a year or more to repay
- you want a fixed instalment and a clear end date that fits your budget
- you know that open credit is a temptation, and a closed account protects you from yourself
- you are paying for one specific thing, such as a vehicle repair, medical bill or deposit
The structure is the protection. You cannot pay less than the instalment without falling into arrears, and you cannot quietly add to the balance. If you are weighing up a mid-sized amount, our article on what a R10,000 loan costs breaks down the fees at that level.
Signs you are using the wrong product
Some patterns suggest the choice has stopped working. Paying only the minimum on a card month after month is the clearest one. So is using a card to cover groceries and fuel because the salary has run out, or drawing cash on a card to make a loan instalment. On the loan side, taking a personal loan to clear a card and then filling the card up again leaves you with two debts instead of one.
If you see these signs, look at the full picture of your monthly commitments before taking on anything new. The debt-to-income calculator shows how much of your income already goes to repayments, which is roughly how a lender will look at it too.
Questions to ask before you choose
Whichever way you lean, a registered credit provider must give you a pre-agreement statement and quotation setting out the cost, and that quotation stays binding for five business days. Use it to compare:
- the interest rate you have been offered, not the advertised range
- the initiation fee and the monthly fee, including any card or account fees
- the cost of credit life cover, which you may replace with an existing policy of your own
- the total you will repay if you stick to the plan you intend to follow
Ask the card issuer what the minimum payment is and how it is calculated, and ask the lender whether you can settle the loan early. Under the National Credit Act you may settle at any time, paying the outstanding balance plus interest and charges up to that date.
If a personal loan looks like the better fit for what you need to pay for, you can compare personal loan offers through Mashonisa. Mashonisa is a comparison service, not a lender, and any offer depends on the lender’s own assessment.
Representative example: estimated repayments on a loan of R30 000 over 36 months at a maximum annual interest rate of 28% would be R1 360 per month, including an initiation fee and monthly service fees. All loans are subject to lender approval, affordability checks, and the lender’s final terms.
