Unplanned or unauthorised overtime
Hours per employee, per week. We've pre-filled a typical premium rate to show how this works, adjust or zero off any of these to match your site.
Calculated at ×1.33
Calculated at ×1.5
Calculated at ×2.0. Not sure which rate applies? Most sites use one or two of these, not all three.
A typical employee can't realistically work more than 30 overtime hours a week across all three rates combined. We've capped your entry to keep the estimate realistic.
