What is a time card calculator?
A time card calculator turns the punches on a physical or digital time card into total worked hours and gross pay. You enter clock in and clock out, subtract any unpaid break, and add an hourly rate to get the wages owed for that shift in a single step.
Time cards — the paper or electronic records that track when an employee clocks in and out — are the basis of hourly payroll. Converting them by hand means subtracting times, borrowing across 60-minute hours, removing break minutes, and dividing by 60 to reach decimal hours. Each step is a chance to slip a digit, which is why a calculator is the standard tool for the job.
This calculator also handles overnight punches. If clock out is earlier than clock in — for example 22:00 to 06:00 — the tool adds 24 hours so the duration is measured correctly without you having to track day rollover manually.
How to calculate time card hours and pay

Enter clock in and clock out
Type the punches in HH:MM format, like 08:00 and 17:00. AM/PM suffixes are also accepted.

Subtract unpaid break
Enter the unpaid break in minutes, such as 30 for a half-hour lunch. Paid breaks can be left as 0.

Enter your rate
Type your hourly rate to see gross pay alongside the total hours, ready for your paycheck or invoice.
