How to Calculate Total Work Hours & Pay

Payroll software calculates hours in decimals rather than hours and minutes. To convert minutes into decimal hours, divide the minutes worked by 60.

Time Card Formulas:

1. Decimal Break Hours = Unpaid Break Minutes ÷ 60

2. Net Hours = Gross Worked Hours - Decimal Break Hours

3. Regular Hours = Minimum(Net Hours, 40)

4. Overtime Hours = Maximum(Net Hours - 40, 0)

5. Gross Pay = (Regular Hours × Base Rate) + (Overtime Hours × Base Rate × Overtime Multiplier)
