Why Overtime Calculations Break Payroll and What Automation Requires
Overtime calculation errors survive into paychecks not because anyone gets the 1.5x formula wrong, but because the data feeding that formula was never clean to begin with. Across industries like construction, manufacturing, warehousing and staffing, the pattern is consistent: unclassified hours types, misconfigured workweek boundaries and missing pay-rule flags produce errors long before the multiplication step. EasyClocking by WorkEasy Software has observed that teams who close payroll without manual reconciliation fix the data pipeline first. The math takes care of itself.
What You Need to Know
The formula is not where errors start
Overtime calculation errors almost always originate upstream, in shift classification, workweek boundaries and hours-type labeling, not in the 1.5x multiplication itself.
Premium pay confusion is a labeling gap
Conflating straight-time overtime with the overtime premium (the additional 0.5x) leads to double-counting or underpayment. Time records that do not distinguish the two force payroll processors to interpret rather than calculate.
