You came early on Monday (😉), and on Tuesday, you skipped your lunch break. On Wednesday, sleep finally caught up with you - payday is getting closer and closer, your work hours are getting crazier and crazier, and you need to fill in this damned payroll form - no worries, this free time card calculator will take a weight off your shoulders.

No more toiling over converting minutes in Excel timesheets - this work hours calculator will compute your weekly working time, overtime, and pay due, so you can relax and relish your coffee.

Just put in the numbers, read on, and chill out.

How to use the time card calculator

The basic functionality of this timesheet calculator is to enable you to conveniently check how many hours you spent working in a given week.

To make use of the work Hours calculator's computing powers, follow the instructions below:

  1. If your unpaid break is the same each day, put its length into the appropriate field of the payroll hours calculator. If it isn't - just change the setting in the first field to cause the "break" fields to appear next to each day. This way, you can input different values for Monday, Tuesday, etc.

  2. If you work on weekends, change "no" to "yes" in the appropriate field. Additional fields for Saturday and Sunday will appear in the timesheet calculator.

  3. Fill out the time you start and finish working for each day of the week (if you don't work on a particular day, select and delete the time values in those two fields). You can do that by clicking the calendar icons (in the "start" and "end" fields) and choosing the time or typing in the times in 12-hour format (10:00 AM, 4:00 PM, etc.)

  4. Once you've entered your work schedule, you'll find the number of working hours at the bottom of the work time calculator.

Advanced options in the timesheet calculator

Apart from finding your weekly working time, the work hours calculator can help you determine:

  • the number of hours you worked on each day of the week
  • overtime
  • overtime pay
  • total pay
  1. To get these results, hit the "advanced mode" button at the bottom of the payroll hours calculator.

  2. You'll immediately see the number of hours you worked on each day of the week.

  3. To calculate overtime, input the number of hours per week after which your employer counts over time. By default, it is set to 40 hours.

  4. Enter your base hourly pay rate and overtime pay rate. If you didn't do any overtime, enter just the standard pay rate. You'll then see how much you earnt in a given week.

  5. You can switch on autosaving values by clicking the grey area on the right of each field and choosing "autosave." This will make the timesheet calculator remember your inputs so that if your hours stay the same or vary slightly, you won't have to enter the hours again the next time you open the calculator.

Work time conversion without the time card calculator

If you'd like to calculate working hours for payroll without the help of this free time card calculator, you may need to know how to convert from minutes to decimal hours. The problem is we use the sexagesimal system for calculating time, so, for example, 1 h 18 min doesn't equal 1.18 h. It equals 1.3 h.

Why? - An hour has 60 minutes. Therefore, 1 minute equals 1/60 of an hour. If you want to convert minutes to hours, multiply the number of minutes by 1/60.

For example, you worked 2 h 27 min on Monday and 3 h 15 min on Tuesday. Say you earn $20/h and want to check how much you've earned on these two days. To do that:

  1. Add minutes to minutes and hours to hours:

    minutes = 27 min + 15 min

    minutes = 42 min

    hours = 2 h + 3 h

    hours = 5 h

  2. Convert the minutes to hours:

    42 min = 42 * 1/60 h

    42 min = 0.7 h

    You can also use the time unit converter if you want to save yourself the effort.

  3. Add converted minutes to hours:

    working time = 5 h + 0.7 h

    working time = 5.7 h

  4. Multiply the working time by your hourly pay rate:

    pay = 5.7 * $20

    pay = $114

    Well done, you've earned $114.
