DEFINITION of 'Man-Year'

A method of describing the amount of work done by an individual throughout the entire year. The man-year takes the amount of hours worked by an individual during the week and multiplies it by 52 (or the number of weeks worked in a year). The man-year calculated will be different for various industries depending on the average number of hours worked each week and the number of weeks worked per year.


There are two main reasons why an organization may calculate the man-year applicable to its employees.

For one, that organizations may use the man-year along with sales or cost figures as a performance metric. For example, a company may calculate a sales per man-year metric and compare it to values from previous years.

The second reason a company would calculate the man-year would be for budgetary reasons. For example, a corporation may calculate the total man-years for various offices that it operates and allocate budgets according to office size.
