How personal loan costs are calculated
Your monthly instalment is calculated the same way as a bond repayment — the loan amount, interest rate, and term combine into an equal monthly payment, with more of each instalment going to interest early on and more to capital later. Personal loans just usually charge a higher rate over a shorter term, since they're unsecured.
On top of interest, lenders typically charge a once-off initiation fee (deducted up front or added to the loan) and a monthly service fee for the life of the loan. Both are required disclosures under the National Credit Act, but they're easy to skim past when you're just looking at the monthly instalment number.
This calculator adds the initiation fee and all monthly service fees to the interest charged, so 'total cost of borrowing' reflects everything you'll actually pay above the amount you borrowed — not just the interest line.
Add an extra monthly payment or a once-off lump sum above and this calculator shows you what that does directly — how many months and how much interest you'd cut by paying more than the minimum.
Frequently asked questions
How is a personal loan instalment calculated?
Your monthly instalment comes from the loan amount, the interest rate, and the term in months, spread into equal payments using the standard amortization formula — the same maths used for a bond, just usually at a higher rate over a shorter term since personal loans are unsecured.
What's included in the total cost of borrowing?
This calculator adds total interest, the once-off initiation fee, and every monthly service fee charged over the term, so 'total cost of borrowing' reflects everything you'll pay above the amount you borrowed — not just the interest line on its own.
Why do personal loans have higher interest rates than bonds?
Personal loans are unsecured — there's no asset like a property backing the loan for the lender to recover if you default. That extra risk is why personal loan rates typically run well above bond rates, often into the 20s percent, even for borrowers with good credit.
Are initiation and service fees required disclosures?
Yes — in South Africa, the once-off initiation fee and the monthly service fee are required disclosures under the National Credit Act, and both are capped by regulation. Your loan agreement should state both fees clearly; this calculator lets you enter your actual quoted amounts to see their real effect on total cost.
How much can extra payments save on a personal loan?
Because personal loan rates run higher than most other consumer debt, even a modest extra monthly payment or lump sum can cut a meaningful chunk off both the term and the total interest. Add an extra payment or lump sum above to see the exact saving for your loan amount, rate, and term.
