To calculate the attrition rate for any given month, you need to know the total number of employees at the beginning of the month.  Then, you need to know the number of new employees added that month.  Finally, determine the number of employees who left.  The number of employees who left is the number of attritions.  Plug the numbers into the following formula: Attrition Rate = Number of Attritions/Average Number of Employees *100. For example, suppose a telecommunications company had 150 employees as of April 1, 2015.  During that month, 20 employees voluntarily left the company.    Also, the company hired 25 new employees. First, calculate the average number of employees.  The beginning number was 150.  If 20 people left and 25 people were hired, then the ending number was 155.  The average number of employees for that month can be calculated with the equation (150+155)/2=152.5{\displaystyle (150+155)/2=152.5}. Next calculate the monthly attrition rate.  In this month, 20 people left, and the average number of employees was 152.5.  The monthly attrition rate can be calculated with the equation (20/152.5)∗100=.1311∗100=13.11{\displaystyle (20/152.5)*100=.1311*100=13.11}  The attrition rate for April, 2015 was 13.11 percent. Use the same formula.  However, instead of one month of data, you will look at the data for one quarter, which is three months.  Suppose the telecommunications company in the above example wants to calculate its attrition rate for the second quarter of the 2015.  This would be April, May and June 2015.  The beginning number of employees on April 1, 2015 was 150.  Over the course of the quarter, 30 people left and 40 new employees were hired.  Therefore, the ending number of employees on June 30, 2015 was 150−30+40=160.{\displaystyle 150-30+40=160.}  The average number of employees for the quarter was (150+160)/2=155{\displaystyle (150+160)/2=155}. The attrition for the second quarter of 2015 was (30/155)∗100=19.35{\displaystyle (30/155)*100=19.35}, or 19.35 percent. For this calculation, you need to know the total number of attritions for the year.  Then, you need to calculate the weighted average of employees.  Using the weighted average is more mathematically accurate since it smooths the effect of seasonal changes in the number of employees a company has throughout the year.  Suppose the telecommunications company in the above example had a total of 62 attrition for the year. They typically hire 20 percent more employees for the last quarter of the year for their busy season.  So, they have an average of 155 employees for the first three quarters, and an average of 186 employees for the last quarter. Knowing that there are four quarters in a year, you could calculate the weighted average with the formula ((155∗.75)+(186∗.25))=(116.25+46.5)=162.75{\displaystyle ((155*.75)+(186*.25))=(116.25+46.5)=162.75}. You could also use the number of weeks worked.  There are 52 weeks in a year.  In the first three quarters, there are 39 weeks, and in the last quarter there are 13 weeks.  Use the formula ((155∗39)/52))+((186∗13)/52))=116.25+46.5=162.75{\displaystyle ((155*39)/52))+((186*13)/52))=116.25+46.5=162.75}. Finally, you could use the number of hours worked.  In a year, there are 2080 work hours.  In the first three quarters, there are 1,560 hours, and in the last quarter there are 520 hours.  Use the formula ((155∗1,560)/2080))+((186∗520)/2080))=116.25+46.5=162.75{\displaystyle ((155*1,560)/2080))+((186*520)/2080))=116.25+46.5=162.75}  The weighted average of employees for this company is 162.75. Calculate the annual attrition rate with the formula (62/162.75)∗100=38.09{\displaystyle (62/162.75)*100=38.09}, or 38.09 percent.

Summary: Calculate the monthly attrition rate. Calculate the quarterly attrition rate. Calculate the annual attrition rate.
