Dear Shelly, thanks for the kind words, we're glad you find the information useful. The formula which our team used to create the calculator, relies on some industry stand information about the size of an email etc, the actual formula looks like this:
var hourly_salary = f.year_salary.value / 240 / 8;
f.user_prod_lost.value =
Math.round ( ( ( f.email_users.value * 0.1 * f.spam_per_user.value * f.year_count.value * hourly_salary ) / 60 ) * 240 );
f.store_cost.value =
Math.round ( ( ( ( f.email_users.value * f.spam_per_user.value * /* Msg Size */ 19000) / 1048576 ) * /* Storage MB */ .35 ) * /* Days msg stored */ 3 * 365 * f.year_count.value * /* Intl Factor */ 1 );
f.mgmt_cost.value =
Math.round ( ( /* IT mgmt time */ 10 / 60) * hourly_salary * /* Annual work days */ 240 * f.year_count.value * /* Intl factor */ 1 );
f.downtime_cost.value =
Math.round ( hourly_salary * /* Potential downtime */ 1 * 12 * f.year_count.value * /* Intl Factor */ 1 );
f.total.value = Math.round ( f.user_prod_lost.value ) +
Math.round ( f.store_cost.value ) +
Math.round ( f.mgmt_cost.value ) +
Math.round ( f.downtime_cost.value );
(Raj, our technical wizard has produced a broken down formula based on 1 email for 1 user) below to help explain the above:)
calculator assumption
Msg size =19000 kb
spam email size =.35 MB
1Mb cost =3
Megabyte = 1048576
if
email user=1
spam mail per day =1
year =1
store_size = (1*1*19000)/1048576)*.35
= 0.00634…
cost per mail = 0.00634 *3
=0.0190
per year = 0.0190 * 365
= 6.9444
= 7
And Then the caculator weighs that information against the average salary informaion you've put in for your company or department and breaks down those costs again for the final total.
According to Raj, it's "just simple math".
Yeah uh huh right!
