How to calculate interest on late payment South Africa?

Last Updated on September 21, 2023 by ufiling

In South Africa, the calculation of interest on late payments is governed by the provisions of the Prescribed Rate of Interest Act (Act No. 55 of 1975) and the National Credit Act (Act No. 34 of 2005). The specific method for calculating interest on late payments can vary depending on the type of transaction and the terms of the agreement between the parties involved. However, I can provide you with a general overview of the calculation process.

  1. Determine the Applicable Interest Rate: The Prescribed Rate of Interest Act sets the maximum interest rate that can be charged on late payments in South Africa. As of my knowledge cutoff in September 2021, the prescribed rate was 10.25% per annum. It is advisable to check the latest updates to ensure you have the most accurate information regarding the prescribed interest rate.
  2. Identify the Late Payment Period: Determine the number of days or months that the payment is overdue. This period typically starts from the agreed-upon payment due date until the actual date of payment.
  3. Calculate the Daily Interest Rate: Divide the annual interest rate by the number of days in a year (365 or 366 for leap years) to obtain the daily interest rate. For example, if the annual interest rate is 10.25%, the daily interest rate would be approximately 0.028%.
  4. Calculate the Interest Amount: Multiply the outstanding payment amount by the daily interest rate and then multiply it by the number of days the payment is overdue. This will give you the interest amount payable for the late payment.
  5. Add the Interest Amount to the Principal: Once you have calculated the interest amount, add it to the original outstanding payment to determine the total amount payable.

It is important to note that this is a general guideline, and the specific terms and conditions of the agreement or legislation may modify the calculation method.
