FTE stands for Full-Time Equivalent, which is a measure of the total number of full-time workers in your company, taking into account both full-time and part-time employees. In Workday, it's calculated by adding up the total hours worked by all employees and dividing that by the standard full-time hours per week, which is usually 40 hours. For example, if you have two part-time employees working 20 hours a week each, their combined FTE would be 1, because 40 hours is the equivalent of one full-time employee. This metric affects headcount reporting, but not directly payroll, as payroll is based on individual employee hours worked and salary rates.
