Timesheet Calculator
Build a weekly timesheet summary in minutes. Enter daily shifts, deduct breaks, and export totals for payroll, invoicing, and compliance reporting.
Build a Weekly Timesheet Summary
Enter each day's work hours as a separate row to compile a weekly timesheet total. The Timesheet Calculator sums all entries, subtracts break periods, and outputs the net total in HH:MM:SS, total minutes, and total seconds.
Quick 3-step process to build a timesheet:
- Enter Monday's work hours in the first row (hours, minutes, seconds).
- Click Add Row for each additional day. Set break rows to − (subtract) to deduct unpaid time.
- Read the weekly total in the result panel. Copy the value for payroll or invoicing systems.
Enter up to 7 daily rows for a standard work week, or add more for multi-week timesheets, contractor billing periods, or project-based tracking.
Each row operates independently. Combine full-time, part-time, and overtime entries in a single timesheet calculation.
Timesheet Rounding Rules
Many payroll systems round timesheet entries to the nearest increment. The 3 most common rounding methods are quarter-hour (15 minutes), tenth-hour (6 minutes), and half-hour (30 minutes).
Quarter-Hour Rounding: Rounding each time entry to the nearest 15-minute increment. 7 minutes rounds down to 0; 8 minutes rounds up to 15 minutes.
Tenth-Hour Rounding: Rounding each time entry to the nearest 6-minute increment (0.1 hours). 3 minutes rounds to 0; 4 minutes rounds up to 6 minutes.
Common timesheet 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
This calculator displays exact (unrounded) values. Apply your employer's rounding policy after reading the result.

Timesheets must comply with local labor laws. In the United States, the FLSA requires employers to track and compensate all hours worked, including overtime past 40 hours per week.
Timesheet Examples and Practical Uses
Explore 4 common scenarios where the Timesheet Calculator streamlines weekly time tracking:
Log a Standard Monday–Friday Work Week
Enter 5 daily entries of 8 hours each. The total — 40 hours 0 minutes (40:00:00) — confirms a standard work week with 2,400 total minutes for payroll.
Track a Part-Time Weekly Schedule
Sum 3 part-time shifts of varying length. The total — 18 hours 30 minutes (18:30:00) — converts to 1,110 total minutes for the pay period report.
Build a Contractor Invoice Period
Compile 4 project blocks for a biweekly contractor invoice. The 52 hours 45 minutes (52:45:00) total — 3,165 minutes — multiplied by the hourly rate produces the invoice amount.
Roll Up Team Hours for Reporting
Sum 4 team members' weekly hours into a department total. The 152 hours 30 minutes (152:30:00) total supports labor budgeting and headcount analysis.
Exporting Timesheet Data
Timesheet 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.
Export the HH:MM:SS value for standard timesheets. For decimal-hour payroll systems, divide total minutes by 60 (e.g., 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.
