First of all, to find out the payroll hours, it is essential to note down the time an employee comes in and goes out each day after that it is possible to deduce how much time an employee has worked by subtracting the start time from the end time However, that's the gross time one is present when at work. One needs to subtract the time not paid to break from the total time to get the actual time at work. After that, total working hours each day have to be added up to get the entire working hours during the payroll period. So, for instance, if on a certain day one works from 9 a. m. to 5:30 p. m. and takes a half-hour break which is not paid, the total work time is 8 hours. Don't forget to take into account the extra time if any. Time worked after the standard work hours (ex. 40 hours per week) are treated separately and paid at double rate. Lastly, regular time and extra time should be separately multiplied by their respective wage rate to arrive at the pay.
