Formula, assumptions & limitations

Inputs used: Base hourly rate ($); Fixed differential per qualifying hour ($); Additional differential (%); Regular qualifying hours; Other regular hours; Overtime qualifying hours; Overtime multiplier.

Method: Qualifying straight-time rate = base rate + fixed differential + base rate × percentage differential. Regular qualifying hours use that rate; qualifying overtime hours multiply that full rate by the entered overtime multiplier.

This is a single-rate scenario that includes the entered differential in qualifying overtime pay. It does not derive a legal weighted-average regular rate across multiple rates or bonuses. Confirm eligibility, overtime threshold, stacking rules, union terms, and payroll policy.

How this tool works

The qualifying straight-time rate adds the fixed and percentage differentials to base rate. Regular qualifying hours use that rate, and qualifying overtime multiplies the full qualifying rate by the entered factor.

Assumptions

The qualifying rate adds fixed and percentage differentials to base pay, and qualifying overtime multiplies that full rate. The visitor classifies qualifying hours.

Limits to know

The estimate assumes the entered hours qualify for the selected differential. Overtime interaction, weekend rules, union terms, stacking rules, and payroll rounding may differ.
