Timesheet Calculator
How It Works
Enter each day's work hours as a separate row to compile a weekly total. The calculator sums all entries, subtracts break periods, and outputs the net total in HH:MM:SS, total minutes, and total seconds.
Three simple steps:
- Enter Monday's work hours in the first row (hours, minutes, seconds).
- Click Add Row for each additional day. Set break rows to minus (subtract) to deduct unpaid time.
- Read the weekly total in the result panel. Click Copy Result for payroll or invoicing systems.
Enter up to 7 daily rows for a standard work week, or add more for multi week billing periods, contractor invoicing, or project based tracking.
Each row is independent: combine full time, part time, and overtime entries in a single calculation.
What Is the Formula?
The timesheet formula is: <strong>Weekly Total = Mon + Tue + Wed + Thu + Fri minus Breaks</strong>. Enter each day's hours and deduct unpaid periods. The calculator normalizes all values using base 60 carry over for accurate totals.
Common rounding increments:
- 15 minute rounding: 1h 07m rounds to 1h 00m; 1h 08m rounds to 1h 15m
- 6 minute rounding: 1h 02m rounds to 1h 00m; 1h 04m rounds to 1h 06m
- 30 minute rounding: 1h 14m rounds to 1h 00m; 1h 16m rounds to 1h 30m
Use the live converter below to see how timesheet hours translate between HH:MM:SS and total minutes for payroll data entry.
Worked Example
See 4 common scenarios where the calculator streamlines weekly time tracking:
Log a Standard Monday to Friday Work Week
Enter 5 daily entries of 8 hours each. Formula: 8h × 5 = 40h 00m (40:00:00). This confirms a standard work week with 2,400 total minutes for payroll.
Track a Part Time Weekly Schedule
Sum 3 part time shifts: 6h 00m + 6h 30m + 6h 00m = 18h 30m (1,110 total minutes for the pay period report).
Build a Contractor Invoice Period
Compile 4 project blocks for a biweekly invoice. Total: 14h 30m + 12h 15m + 13h 00m + 13h 00m = 52h 45m (3,165 minutes × hourly rate = invoice amount).
Roll Up Team Hours for Reporting
Sum 4 team members' weekly hours. Calculation: 40h + 38h 30m + 36h 00m + 38h 00m = 152h 30m total for labor budgeting and headcount analysis.
Exporting and Formatting
Results display in 3 formats: HH:MM:SS for standard reporting, total minutes for billing systems, and total seconds for granular data exports. Click Copy Result to transfer the value directly to your clipboard.
For decimal hour payroll systems, divide total minutes by 60. For example, 2,400 minutes ÷ 60 = 40.00 decimal hours.
Maintain a separate row for each day to create an auditable timesheet trail. Avoid combining multiple days into a single row: individual entries simplify corrections and approvals.
