Example Calculation

Suppose, for instance, you wish to borrow R50,000 for a personal loan with an interest rate of 15% per annum repayable over 24 months. This is how you use the calculator: Loan Type: Personal Loan Loan Amount: R50,000 Interest Rate: 15% Repayment Period: 24 months Upon calculating, the loan calculator will provide you with:
  • Monthly Payment: The amount you need to pay each month.
  • Total Payment: The total amount you will repay over the loan period.
  • Total Interest: The total interest you will pay over the life of the loan.

Factors Affecting Loan Calculations

Several factors could affect what you end up paying on the loan you have calculated above. Understanding these can help you make more informed choices:

1. Loan Amount

The more you borrow, the higher your monthly repayments and the total cost of the loan. The bigger the loan, the more you repay each month and the more interest you pay over the loan term.

2. Interest Rate

The interest rate is the cost associated with borrowing. The higher the rate, the more expensive your monthly payments and total loan become. The lower the rate, the more affordable your loan will be. Interest rates may be fixed (constant through the life of the loan) or variable (fluctuating with the market).

3. Repayment Period

How long it takes to pay back the loan determines how much you pay each month. It costs less each month to pay over a long period, but it leads to greater total interest paid, while selecting a shorter period cost more each month but ends up with lower total interest.

4. Fees and Charges

Other lenders might charge fees, such as origination fees, late-payment fees or early repayment fees, which could influence how much you pay for a loan.
