Sick Day Cost Calculator

According to Safe Work Australia and various HR surveys, Australian employees take an average of 7–9 unplanned absence days per year. This figure varies by industry: healthcare workers and teachers typically take more; professional services workers tend to take fewer. Full-time employees are entitled to 10 days of paid personal/carer's leave under the National Employment Standards.

Three hidden costs inflate the real number. First, employer on-costs: superannuation (11.5%), payroll tax, workers compensation, and other levies add roughly 20% to the direct salary cost. Second, productivity loss: the work still needs to be done — either by someone else at overtime rates, a temp agency, or it goes undone and creates a backlog. Third, role multiplier: a revenue-generating salesperson or senior engineer produces far more value per day than their daily salary reflects.

Research consistently shows that Employee Assistance Programs (EAPs), flexible working arrangements, flu vaccinations, and mental health support have the strongest ROI for reducing absenteeism. AHRI data suggests that organisations with strong wellness cultures see 30–50% lower unplanned absence rates. Even reducing from 8 to 5 sick days/year on a team of 10 at $80,000 average salary saves roughly $25,000–$30,000 annually.
