Pay period start date:

Payroll period starting date:

Select the month, day, and year of the semi-monthly pay period you want the timesheet calculator to start at. The Day column will automatically be filled in with the correct days and dates.

Note that in order for the calculator to operate, the number of days between the selected starting and ending pay period dates must be greater than 12 and less than 18. Timeframes that fall outside of 13-17 days will cause the In/Out fields to be cleared.

Hours.hours from partial week of previous pay period:

If you pay Overtime after 40 hours per week, this field allows you to enter the time worked in a partial workweek from the last pay period. This time will be used to calculate any overtime that may be earned in the remainder of the workweek that occurs at the beginning of the current pay period. Note that the time must be entered in an HH.HH format (6 hours and 30 minutes would be entered as 6.50).

Time totals as hours:minutes or hours.hour-fraction:

If you would like the calculator to display time totals in hours:minutes format (7:30), choose the HH:MM option.

Or, if you would like the calculator to display time totals in hours:fractions-of-hours format (7.5), choose the HH:HH option.

Enter Time Card Hours

Enter your time card hours:

Depending on the width of the calculator, a different entry form will be displayed. Narrow widths will display a mobile optimized form, whereas wider widths will display a desktop optimized form.

For each day in the period that you accumulated work time, tap the "+" icon to expand the day. Next enter the In and Out times for each time block you were getting paid for. Once each day is completed you can either leave the day expanded, or tap the "-" icon to collapse the In/Out times.

Important! When entering times only use numeric characters 0-9 with or without decimal points (no colons). The calculator will know that "130" means "1:30" and will insert the colons for you in the results.

Important! You can enter times in standard (130) or military (1330). However, if a time block exceeds a 12 hour period you will need to use military time instead of standard time. If you're not sure what the military time equivalent of a standard time is, tap the grid icon in this row to open the Military Time Conversion Chart.

Total time for pay period:

About the Semi-Monthly Time Sheet Calculator

Veins in Forehead Bulging Out?

This calculator was created at the request of a site visitor who wrote:

Can you make this one? Overtime is calculated weekly over 40 hours, the pay periods are the 1st-15th & 16-EOM. Pay dates are the 13th and 28th. This is nearly impossible to figure out as some overtime is paid in the next pay period all the time and it is difficult to keep track of this on paper without the veins in my forehead bulging out!!

Turns out this email created a mental image that motivated me into action. I care too much about my site visitors to have them walking around with bulging veins in their foreheads.

Well, after a few bulging veins of my own I think I managed to come up with a way to reduce the swelling for the quoted visitor and for anyone else who can relate.

Easily Track Weekly Overtime for Semi-Monthly Pay Periods

If you have been trying to track weekly overtime for semi-monthly payroll periods on paper, I'm hoping this calculator will help to reduce the swelling of the veins on your forehead that may be occurring during your semi-monthly payroll processing.

How so?

If you select the Overtime after 40 hours per week option, the Semi-Monthly Timesheet Calculator will calculate the work time for the partial workweek that occurs at the end of the pay period -- and then includes that figure on the printable hours and wages report.

Next, the calculator provides a field at the top to enter the partial workweek time from the previous pay period report.

And finally, the calculator adds the previous partial workweek time to the current partial workweek time, calculates any overtime wages earned for the overlapping week, and then converts the appropriate current number of regular hours to overtime hours.

Viola! No more bulging veins ... at least I hope that is the case. If not, please let me know why not and I will do my best to correct the situation.

Instructions

How to use the Semi-Monthly Time Sheet Calculator

Step #1:

Enter the name of the person you want to enter and track hours for.

Step #2:

If you would like the calculator to calculate gross wages, enter the hourly wage rate and overtime settings for the person you are entering and tracking hours for.

Step #3:

If you pay overtime for more than 40 hours per workweek, select the day of the week your workweek starts on. If you pay overtime based on any other criterion, this field will be greyed out.

Step #4:

Select the pay period start date.

Step #5:

Select the pay period end date.

Step #6:

If you pay overtime for more than 40 hours per week, enter any carryover hours due to a partial workweek in the last pay period.

Step #7:

Select your preference for how the calculator formats the time totals (HH:MM or HH.HH).

Step #8:

For each workday in the pay period, open the corresponding day title and enter your In and Out times for that day. The calculator will update the total each time you enter a new In/Out pair of times.

Step #9:

Once all In/Out times are entered for all of your workdays, and if you completed the required regular and overtime wage entries in the top section of the calculator, you can tap the "Calculate Gross Pay" button. This will populate the hours and wage detail table located just below the button.

Step #10:

Tap the "Printer Friendly Report" to open a wage and hours report that you can print out and file for your records. If you need to email the report to your payroll clerk (if your printer software provides a Print to PDF feature) printing to a PDF file will allow you to attach the report to an email.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
