About Hours Calculator

The Hours Calculator accurately computes total time worked between clock-in and clock-out timestamps, subtracts unpaid lunch and break deductions, and converts the resulting shift into both hours/minutes and decimal hours for payroll computation.

What is Hours Calculator?

The Hours Calculator accurately computes total time worked between clock-in and clock-out timestamps, subtracts unpaid lunch and break deductions, and converts the resulting shift into both hours/minutes and decimal hours for payroll computation.

How to Use This Calculator

  1. Select shift start hour, minute, and AM/PM.
  2. Select shift end hour, minute, and AM/PM.
  3. Enter unpaid break or lunch minutes.
  4. Optionally enter your hourly wage rate to calculate gross daily earnings.

The Mathematical Formula & Variables

Total Minutes = (End Time - Start Time in minutes) - Break Minutes; Decimal Hours = Total Minutes / 60; Gross Pay = Decimal Hours * Hourly Rate

Step-by-Step Worked Example

Scenario: Shift from 8:30 AM to 5:00 PM with a 45-minute lunch break at $25.00/hour.

  1. Convert 8:30 AM to minutes from midnight: (8 * 60) + 30 = 510 minutes.
  2. Convert 5:00 PM (17:00) to minutes: (17 * 60) = 1,020 minutes.
  3. Gross elapsed time: 1,020 - 510 = 510 minutes (8 hours 30 minutes).
  4. Subtract 45-minute lunch: 510 - 45 = 465 net minutes = 7 hours 45 minutes.
  5. Decimal hours: 465 / 60 = 7.75 hours. Gross pay = 7.75 * $25 = $193.75.

Result: Duration: 7 Hours 45 Min (7.75 hrs) | Pay: $193.75

Frequently Asked Questions

How do I convert minutes to decimal hours for payroll?

Divide the minutes by 60. For example: 15 minutes = 0.25 hours, 30 minutes = 0.50 hours, and 45 minutes = 0.75 hours.

How are overnight shifts crossing midnight calculated?

If the end time is earlier than the start time, add 24 hours (1,440 minutes) to the end timestamp before subtracting the start time.
