Understanding Interest Rate Types in South Africa

In South Africa, there are different types of interest rates you might encounter:

  • Prime Interest Rate: The base rate set by South African banks (currently linked to the repo rate)
  • Fixed Interest Rate: Stays the same throughout the loan term
  • Variable Interest Rate: Changes with the prime rate
  • Compound Interest: Interest calculated on the principal plus accumulated interest
  • Simple Interest: Interest calculated only on the principal amount

💡 Pro Tip: Even a 1-2% reduction in interest rates through debt counselling can save you thousands of Rands over the life of your loans. Use our calculator to see the difference!
