In business, when someone refers to a year to date, they usually refer to the period from the beginning of the current year to either the present or a specific future date. This can be used to measure progress or analyze performance against goals. For example, if you had set a goal to increase revenue by 20% by the end of the year, you could use year-to-date figures to see how close you are to reaching that goal.
Attrition Rate = Number of Attritions/Average Number of Employees *100
This is the attrition rate or percentage of employees who left during the period divided by the average number. To calculate it, divide the number of employees who left during the period by the average number of employees and multiply by 100.
