Calculating Call Center costs of CSRs

We had a client that wanted to calculate the amount of money people spend on transferring help-desk calls to Customer Service Representatives based on:

• Number of annual calls
• Percentage of calls transferred to CSRs
• Average hourly wage of CSRs

So, the formula they needed was ([annual calls] * ([% transferred] / 100)) * ([Avg Wage] / 60)

• Computed Code: $node_field[0]['value'] = ($node->field_1_calls_per_year[0]['value'] * ($node->field_2_to_supervisor[0]['value']) / 100) * ($node->field_3_csr_wage[0]['value'] / 60);
• Display format: $display = '$' . $node_field_item['value'] . '.00';
• Data type: Integer (we wanted to round to the nearest dollar)
• Data length: 10,2
• Default Value: 0
