Time Card Calculator

 

Add your start time, end time, and unpaid breaks for each day. Calculate total work hours in hours and minutes or decimal hours. Leave unused days empty.

Calculate your work hours

Use 24-hour times: type 0900 for 09:00 or 1730 for 17:30. The colon appears automatically as you type. An end time earlier than the start time means the shift ends the next day. Identical times count as zero hours, not 24 hours. Enter one shift per day.

How to use the time card calculator

1. Enter the start and end time in 24-hour format. You can type 0900 or 09:00 for 9:00 AM, and 1700 or 17:00 for 5:00 PM.
2. Enter the total unpaid break time in whole minutes. Leave paid breaks out of this deduction.
3. Choose the optional 40-hour split if it helps with planning, then select Calculate hours.

How work hours are calculated

Work time = end time − start time − unpaid breaks. For an overnight shift, 24 hours are added before subtracting the start time. Weekly time is the sum of the entered shifts.

Example: 9:00 AM to 5:00 PM with a 30-minute break

The shift lasts 8 hours. Subtracting 30 unpaid minutes gives 7 hours 30 minutes, or 7.50 decimal hours. Five identical shifts total 37 hours 30 minutes.

Example: an overnight shift

A shift from 10:00 PM to 6:00 AM lasts 8 hours. With a 30-minute unpaid break, the result is 7 hours 30 minutes. Enter the entire shift on the day it starts; the tool does not split it across days or workweeks.

Frequently asked questions

Is 7 hours 30 minutes the same as 7.30 hours?

No. Divide minutes by 60: 30 ÷ 60 = 0.50, so 7 hours 30 minutes equals 7.50 hours. A value of 7.30 decimal hours equals 7 hours 18 minutes.

Does this calculate overtime pay?

No. The optional split shows hours up to and above 40 in the entered week. It does not apply pay rates, daily overtime rules, exemptions, multiple rates, or state-specific requirements. Actual overtime eligibility and pay depend on applicable law and employment arrangements.

Can I enter multiple shifts in one day?

This version supports one continuous shift per day. It does not combine split shifts. Do not enter an unrelated shift on another day just to make it fit, especially if you use the weekly split.

Does it account for daylight saving time?

No. It subtracts clock times without dates or time zones. Shifts that cross a daylight saving change need a separate check of actual elapsed time.

Does it round punches or calculate wages?

No. It uses whole minutes as entered and deducts only the unpaid break minutes you supply. It does not round punches, calculate wages, or determine whether a break may legally be unpaid. Confirm your entries and employer policies before using a result for payroll.

HandyMetric provides general planning information, not payroll or legal advice. This version supports shifts shorter than 24 hours and does not store a dated time card.
