A monthly instalment can make a loan look affordable while hiding how much it will cost over its full term. To compare South African loan quotations, begin with the total repayable amount and the terms, not just the amount deposited into your account.

Separate the different numbers on a quotation

The loan principal is what you borrow. Interest is the charge for borrowing and depends on the rate and how the agreement calculates it. Initiation fees, monthly service fees and credit-life insurance may increase the total amount you pay. The term determines how long repayments continue. Always ask whether insurance is optional, required or subject to alternative cover under the applicable agreement.

A simple, transparent instalment illustration

Suppose one loan quotation requires R1,250 per month for 24 months. Multiplying gives R30,000 in scheduled repayments. If the amount of credit advanced was R22,000, the difference is R8,000. But do not call the whole R8,000 "interest": it could include different fees and insurance, and the actual total may change if the agreement allows variable-rate changes or other adjustments.

Compare two offers correctly

Offer A asks for R1,250 over 24 months, totalling R30,000. Offer B asks for R990 over 36 months, totalling R35,640. The lower monthly instalment saves R260 in immediate cash flow but would cost R5,640 more in total under these illustrative fixed schedules. This is why extending the term can be expensive. These invented offers are not lender quotations; always read the real credit agreement.

Ask whether the rate can change

Compare fixed and variable interest terms and the consequences of rate changes. Check how an extra payment is applied, whether early settlement is allowed, and which extra costs may apply. Read a current repayment schedule rather than relying on a marketing figure. A nominal annual rate is not always enough to compare agreements with different fees or compounding conventions.

An affordability check before borrowing

Subtract actual essential expenses and all current contractual repayments from reliable take-home income. Leave room for irregular costs and emergencies. If a new instalment uses nearly all remaining money, even a small rise in expenses can lead to missed payments. Consider whether the purchase can wait or whether a smaller amount would meet the need.

Questions to take to the lender

  • How much money will reach my account after any deductions?
  • What is the total amount repayable if I follow the agreed schedule?
  • Which fees, premiums and interest-rate rules apply?
  • What happens if I pay late, settle early or make an extra payment?
  • Can I receive the full quotation and agreement before accepting?

Borrowing is not a revenue strategy

Be cautious of advertisements promoting credit as a way to "fix" an existing debt problem. The National Credit Act regulates consumer-credit practices, but it does not make every loan suitable for every household. Seek support if repayment commitments are already unaffordable.
