Time Card Calculator
Free time card calculator: enter clock-in, clock-out, and break times to get daily and weekly hours, overtime, and pay. No signup.
Enter this week's hours
Add the times you clocked in and out each day, plus any unpaid break. Leave a day blank if you did not work.
Hours and pay for the week
Overtime pay uses a time-and-a-half rate. Adjust the threshold and rate to match your own rules.
Handles night shifts
Enter an end time earlier than the start for overnight shifts. The calculator counts the hours across midnight.
Subtracts unpaid breaks
Breaks are unpaid minutes removed from each day, so the daily and weekly totals reflect paid time only.
Splits overtime pay
Set the weekly overtime threshold and hourly rate to split regular and overtime pay at time-and-a-half.
How the time card calculator works
For each day it converts your clock-in and clock-out times to minutes, removes the unpaid break, and turns the result into decimal hours. The weekly total adds every day, then splits anything above your overtime threshold into overtime hours paid at time-and-a-half.
It is a quick manual check, not a payroll system. When you no longer want to retype times every week, Sandtime.io records hours as you work and turns them into reports and invoices you can trust.
Track time once, not twice
Sandtime.io captures hours as work happens, so weekly totals, overtime, and billable time are ready without a spreadsheet. Free for unlimited users, without screenshots or surveillance.
