Assumptions

  • Employer SG contribution is estimated as 12.0% of gross annual income (ordinary time earnings) — actual OTE may differ from gross salary.
  • Division 293 income is approximated as taxable income after sacrifice plus total concessional contributions — reportable fringe benefits and net investment losses aren't modelled.
  • If Division 293 applies, this calculator applies the combined 30% rate to the entire salary-sacrificed amount as a simplification, rather than only the portion of contributions above the threshold.
  • Assumes the full salary sacrifice amount is contributed for the full financial year, and that gross annual income is unaffected by the sacrifice other than the reduction modelled here.
