Overtime Gross Pay Formula

Gross Pay=(Hreg×R)+(HOT×R×1.5)+(HDT×R×2.0)\text{Gross Pay} = (H_{\text{reg}} \times R) + (H_{\text{OT}} \times R \times 1.5) + (H_{\text{DT}} \times R \times 2.0)

Total gross earnings equal regular hours times base rate plus overtime hours times 1.5x base rate plus double-time hours times 2.0x base rate.
