The Formula
Calculate the exact time difference between two clock times, deduct unpaid break duration, and optionally compute gross pay based on your hourly rate. The total time is computed in hours and minutes (HH:MM) for timesheet readability and also converted to decimal hours (e.g., 8.5) for payroll multiplication. Gross pay is decimal hours multiplied by the hourly rate.
Variable Definitions
Total Time
The time elapsed between the start and end times, minus any unpaid break time. Displayed in both HH:MM and decimal formats.
Gross Pay
Total earnings before taxes and deductions. Calculated as decimal hours × hourly rate. Only shown when an hourly rate is provided.
How to Use This Calculator
- 1
Enter start and end times in 12-hour format with AM/PM (e.g., 9:00 AM, 5:30 PM) or 24-hour format (e.g., 09:00, 17:30).
- 2
Optionally enter your unpaid break duration in minutes (e.g., 30 for a 30-minute lunch break).
- 3
Optionally enter your hourly rate to calculate gross pay.
- 4
View total time in both HH:MM format (for timesheets) and decimal hours format (for payroll systems).
Total work time is calculated as end time minus start time minus break, shown in both HH:MM and decimal formats.
Understanding the Concept
Time calculators are used daily by shift workers, freelancers, contractors, and payroll processors to track hours worked and compute earnings. The tool automatically handles overnight shifts (e.g., starting at 10 PM and ending at 6 AM the next morning = 8 hours) and deducts unpaid break time. Decimal hours (e.g., 8.5 hours) are standard in payroll systems because they simplify wage calculation — just multiply by the hourly rate. HH:MM format (e.g., 8:30) is common on paper timesheets and for human readability. Converting between the two is straightforward: divide the minutes by 60 (e.g., 30 minutes ÷ 60 = 0.5 hours). The calculator performs this conversion automatically.
