Mathematical Formulas
1. Cost Per Ticket
\[\text{Total Monthly Support Expense} = \text{Monthly Support Payroll} + \text{Monthly Support Software}\] \[\text{Cost Per Ticket (\$)} = \frac{\text{Total Monthly Support Expense}}{\text{Total Monthly Resolved Tickets}}\]2. Calculated Team Hourly Rate & Annual Cost
\[\text{Total Agent Resolution Hours} = \frac{\text{Monthly Resolved Tickets} \times \text{Avg Resolution Minutes}}{60}\] \[\text{Calculated Hourly Cost} = \frac{\text{Total Monthly Support Expense}}{\text{Total Agent Resolution Hours}}\] \[\text{Annual Support Expenditure} = \text{Total Monthly Support Expense} \times 12\]Customer Support Cost Benchmark Matrix
