What is a Time Card Calculator?

A time card calculator is an online tool that automatically computes the number of hours worked during a shift or workweek. You enter your start time, end time, and any break durations, and the calculator instantly shows you your total hours worked, regular hours, overtime hours, and estimated gross pay.

Time card calculators are used by hourly workers, payroll managers, freelancers, contractors, students with part-time jobs and small business owners who want a fast, accurate way to track employee hours without expensive payroll software.

How Does a Time Card Calculator Work?

The calculator converts time inputs into minutes, then subtracts break durations, and converts the result back into hours and minutes. Here is the basic formula:

Total Hours = (End Time − Start Time) − Lunch Break − Additional Breaks

For overtime, the calculator compares your total daily or weekly hours against the configured threshold (e.g., 40 hours/week or 8 hours/day) and applies your chosen overtime multiplier (e.g., 1.5×) to any hours above that threshold.

How to Calculate Work Hours Manually

You can calculate work hours manually by converting both times to 24-hour format, subtracting the start time from the end time, and converting the result to hours and minutes.

Step	Example	Result
Start time	8:30 AM	8h 30m = 510 min
End time	5:00 PM	17h 0m = 1020 min
Gross time	1020 − 510	510 min = 8.5 hrs
Lunch break	− 30 min	480 min = 8.0 hrs

How to Calculate Work Hours with Lunch Breaks

Lunch breaks are often unpaid. To calculate paid hours, subtract the lunch break duration from your gross work time. For example:

9:00 AM to 5:00 PM = 8 hours gross
Minus 30 minutes lunch = 7 hours 30 minutes paid
9:00 AM to 6:00 PM with a 1-hour lunch = 8 hours paid
8:00 AM to 4:30 PM with a 45-minute lunch = 7 hours 45 minutes paid

With TimeCalc, you simply enter the lunch break in minutes and the calculator handles the subtraction automatically.

How Overtime Is Calculated

Under the US Fair Labor Standards Act (FLSA), non-exempt hourly employees must receive overtime pay of at least 1.5 times their regular rate for hours worked beyond 40 hours per workweek.

Some US states such as California also require daily overtime. In California, overtime applies after 8 hours in a day, double time after 12 hours in a day, and double time on the 7th consecutive day of work.

In the UK, there is no statutory right to overtime pay, but many employment contracts include overtime provisions. TimeCalc allows you to configure custom overtime rules to match your contract or local law.

Weekly vs Biweekly Timesheets

A weekly timesheet covers a single 7-day work period, typically Monday through Sunday. A biweekly timesheet covers two consecutive weeks (14 days), which is the most common pay period in the United States.

Type	Pay period	OT threshold	Common in
Weekly	7 days	40 hrs/week	Retail, hospitality
Biweekly	14 days	40 hrs/week	Corporate, US standard
Semi-monthly	~15 days (2×/month)	Varies	Salaried, government
