Turn Work Periods Into Clear Hour Totals
A reliable time card makes it easier to understand how much time was actually spent working. Instead of manually adding several shifts and subtracting breaks, this free time card calculator organizes the entries for you and presents a clear daily and weekly summary.
Record Each Work Period
Enter the time you started and finished work for each day. The calculator handles the time difference automatically, including shifts that continue past midnight.
Subtract Unpaid Breaks
Add unpaid break minutes to each workday so your net hours represent the working time rather than the entire time between clock-in and clock-out.
Review Your Weekly Total
Once your entries are complete, you can calculate time card totals and quickly compare regular hours with hours above your selected weekly threshold.

Enter End Time
Add your finishing time. Overnight shifts are supported.
Add Break Minutes
Enter unpaid break time in minutes when it should be excluded from working hours.

What Does a Time Card Calculator Do?
A time card calculator helps convert clock-in and clock-out entries into usable work-hour totals. It is especially useful when a workweek contains different shift lengths, unpaid meal periods, or occasional schedule changes.
The basic calculation is simple: the elapsed time between the start and end of a work period is found first, then any unpaid break minutes are removed. The resulting value represents the net working time for that day.
This calculator is designed for practical time tracking rather than payroll compliance. Your employer's policies, employment agreement, and applicable local laws should always be considered when determining which breaks count as paid working time.
