Why shift costs vary

Penalty rates

Weekend and public holiday shifts can cost 25–100% more than ordinary weekday hours, depending on the award.

Overtime stacking

When overtime applies on top of a penalty day, the multipliers stack — pushing the effective rate well above base.

Breaks reduce paid time

Unpaid meal breaks are deducted from paid hours, so a rostered 8-hour shift may only be 7.5 paid hours.

Superannuation

Super is added on top of gross wages, so every shift costs more than the wages alone suggest.

How small roster changes compound

Penalty rates in Australia commonly range from 125% to 250% of the base rate once weekends, evenings and public holidays are factored in. Because those multipliers apply to every paid hour, small changes — a longer shift, a later finish that tips into a higher rate, or dropping a break — compound quickly across a full roster.

Modelling a single shift first makes the pattern obvious, then you can see how it scales in the roster cost forecast calculator.
