Common mistakes

  • !Using an assumption that is not supported by a current local quote, bill, statement or official source.
  • !Treating a generic estimate as a lender, provider, payroll or tax authority decision.
  • !Mixing monthly and annual inputs without converting them consistently.
  • !Testing only one scenario instead of checking how a cautious assumption changes the result.

What to do next

  • Run a second scenario with a cautious assumption so you can see the downside clearly.
  • Compare the result with the related calculators below before making a decision.
  • Check current local rules, eligibility and provider terms before applying or committing money.
  • Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.

Frequently asked

Yes. If your annual medical aid contributions exceed three times the annual MTC, the excess qualifies as additional medical expenses. SARS allows a credit of 25% of these excess contributions for taxpayers under 65, or 33.3% for those 65 and over or with a disability. Out-of-pocket medical expenses not paid by medical aid also qualify under the additional expenses calculation.
