What to do next

Read the plain-language walkthrough of this hike, then stress-test a full payoff plan if several debts moved at once.
Assumptions
  • Default bond scenario: outstanding balance at prime, 20 years remaining, fully amortising. That term reproduces the published illustrative bumps of about +R168 / +R337 / +R505 to +R506 per month on R1m / R2m / R3m.
  • Sep 2026 move used for defaults: repo 7.00% 7.25%; prime 10.50% 10.75%.
  • Credit cards and overdrafts often reprice too, but they are not amortising instalment loans. Use this tool for bonds, car finance, and personal loans with a remaining term.
