On a Friday afternoon, perhaps, after realizing you were late for clocking in or took too long for lunch, you become nervous about having messed up and getting less money. Let the timesheet hours calculator do the math for you. Simply input your raw clock times. It converts the minutes into decimals for you, saving you the trouble of doing it yourself when you’re fatigued from work.
Do you want to track payroll time? Or do you want to track actualy time? Payroll time is the time that your boss says she will pay you for. Actual time is the time you arrived at work and the time you departed work. There’s a difference. Depending on how your company chooses to round time up or down, this could matter a lot. Some companies round time down, so if it took you six minutes longer than you were supposed to be working, you get no credit for that time. Some companies round to the nearest quarter hour, so if you are only a few minutes late, that delay becomes nothing. The calculator has an option to toggle from one type of rounding to another. Watch as the dollars is impacted by the difference between actual time worked versus billed time.
Why You Should Use a Timesheet Calculator
The math gets tricky when breaks are involved. Perhaps you work an eight hour shift, but have a thirty minute unpaid lunch, so that only counts as seven and a half hours of billable time. Or maybe your schedule vary or is split up. For example, you go on a twenty minute break in the morning, and again in the afternoon. Before you can do any math about whether you’ve hit the overtime mark, you need to remove those minutes from your overall time. It’s easy to fail to remove the break time, and thereby convince yourself that you hit overtime too soon. That happens all the time.
Many assume they should of count every single hour they work towards regular pay. Then when payday comes around, the payroll system will deduct it from their pay. There’s a lot more to this than just overtime rules. Did you know that many folks think that the magic number is forty hours/week? It turns out that some contracts and some states has overtime rules based off daily numbers. Even though you worked 20 hours all week, if you put in an extra ten on Monday then you’ll be owed overtime for those final two hours. Using the tool, you can set daily and/or weekly overtime rules. That way you know whether you’re getting screwed when you put in long days. This is not a substitute for legal advice. But it will help you see what you should get paid prior to payday.)
Most payroll systems process in decimal hours rather than minutes. That means that 15 minutes is.25 hours; 30 minutes is.50 hours. A six minute late punch? It is about.1 hours. Small numbers, but over a year’s time, it adds up. The calculator will convert your weekly number of hours to decimals for you. If your payroll system demands some precision, you can change the number of decimal places.
It is helpful because it is transparent. Because people don’t want to run the calculations themselves, they tend to trust it (most employees anyway). So when you check what was inputted, you see exactly how much your paycheck gets deducted for breaks and rounding. That helps you better understand your true hourly wage. It converts ambiguous time into concrete money.
You no longer have to guess at the split between regular and overtime hour. Knowing the breakdown protects your sense of wellness. It helps you see if you’re being shortchanged.
