Question
How does BA calculate resource overusage amount?
Answer
The details for method of usage/overuse calculation for additive and non-additive resources are provided below:
Additive resource
Overusage = (amount_used - (amount_included + amount_additional) * Duration_Percent) * Overusage_Fee
Non-additive resource
Overusage = (average_amount_used - (amount_included + amount_additional) ) * Duration_Percent * Overusage_Fee
average_amount_used
is calculated as the sum of resource usage on each particular day of month divided by the number of day in month:
(Usage on 1st day of month + Usage on 2nd day of month + ... + Usage on last day of month) / Number of days in month
