Costs shown in GBP. Enter your annual cost per team member in your local currency for equivalent figures. Staff time cost reflects only the coordination overhead percentage you set, not total spreadsheet hours — productive analysis time is excluded. Error resolution is modelled at 2.5 hours per incident. Management time is weighted at 1.4x to reflect typical seniority premium. Calculations assume 40-hour working weeks and 52-week years.
