##### Definition:

Spam e-mails are un-wanted emails, using these e-mails, identical messages are sent to numerous recipients by email. It is used to calculate the corporate cost of spam per employee and it targets on individual users with direct mail messages. Junk email cost affects the time, money and resources of an employee.

#### Formula:

Average salary = Average annual salary / (No of working days x 8 x 3600)
No of Spams = No of emails x Spam Percentage / 100
#### For Company

Wasted time yearly = ( No of spams x Time to read a spam x No of working days / 3000) x No of employees
Daily lost salary = ( No of spams x Time to read a spam x Average salary) x No of employees
Monthly lost salary = Daily lost salary x (No of working days / 12)
#### For Employee

Wasted time yearly = ( No of spams x Time to read a spam x No of working days / 3000)
Daily lost salary = ( No of spams x Time to read a spam x Average salary)
Monthly lost salary = Daily lost salary x (No of working days / 12)
##### Example :

A corporate company 'x' has total number of employees 30.Working days of the company is 235 days per year and the average annual salary given by the corporate company to its employees is 30000.The average e-mail received to the company is 10 where the percentage of spam email is 5%.The time spent to resolve the spam email is 5 sec. Calculate the Average Salary, No of Spams, Yearly wasted time, daily lost salary and monthly lost salary of the company and each employee.

##### Solution:

##### Given,

Working days = 235 per year,
Number of Employees = 30,
Average Annual salary = 30000,
Average emails per day = 10 per person,
Percentage of spam = 5%,
Time spent on each spam = 5 seconds

##### To find,

Average Salary
No of Spams
Wasted time yearly
Daily lost salary
Monthly lost salary

###### Step 1:

Average salary | = Average annual salary / (No of working days x 8 x 3600) |

| = 30000 / (235 x 8 x 3600) |

| = 0.00443 |

###### Step 2:

No of Spams | = No of emails x Spam Percentage / 100 |

| = 10 x 5 / 100 |

| = 0.5 |

##### For Company:

###### Step 1:

Wasted time yearly | = (No of spams x Time to read a spam x No of working days / 3000) x No of employees |

| = (0.5 x 5 x 235 / 3000) x 30 |

| = 5.88 |

###### Step 2:

Daily lost salary | = (No of spams x Time to read a spam x Average salary) x No of employees |

| = (0.5 x 5 x 0.00443) x 30 |

| = 0.33 |

###### Step 3:

Monthly lost salary | = Daily lost salary x (No of working days / 12) |

| = 0.33 x (235 / 12) |

| = 6.51 |

##### For Employee:

###### Step 1:

Wasted time yearly | = (No of spams x Time to read a spam x No of working days / 3000) |

| = (0.5 x 5 x 235 / 3000) |

| = 0.2 |

###### Step 2:

Daily lost salary | = (No of spams x Time to read a spam x Average salary) |

| = (0.5 x 5 x 0.00443) |

| = 0.01107 |

###### Step 3:

Monthly lost salary | = Daily lost salary x (No of working days / 12) |

| = 0.01107 x (235 / 12) |

| = 0.22 |
