Use the interest rate as your starting point

Paying off debt charging 24% produces a certain saving of that interest before fees. An investment return is uncertain and may be taxed outside a tax-free wrapper.

Store accounts, revolving credit and unsecured loans commonly deserve attention before extra investing. A low-rate home loan creates a closer decision.

Use a safe order

  • Pay every required minimum on time.
  • Build a small emergency buffer so the next surprise does not go back onto credit.
  • Capture any valuable employer retirement contribution or match.
  • Direct extra cash to the highest effective debt rate.
  • Increase investing as expensive debt disappears.

Check early-settlement terms

Ask the credit provider for a settlement figure and confirm whether fees or notice apply. Paying extra into a facility is not always the same as closing it.

A simple example

An extra R1 000 paid towards a balance charging 24% avoids a high, certain cost. Expecting an investment to beat 24% after fees and tax would require taking meaningful risk.
