Workshop Capacity Calculator
Calculate your workshop's throughput capacity versus fleet maintenance demand, identify bottlenecks, and determine optimal workshop staffing.
Formula: monthly_capacity_hrs = num_mechanics * working_hours_per_day * working_days_per_month * mechanic_efficiency_pct / 100; pm_demand_hrs = fleet_size * avg_pm_hours_per_vehicle_per_month; reactive_demand_hrs = breakdowns_per_month * avg_reactive_hours_per_breakdown; monthly_demand_hrs = pm_demand_hrs + reactive_demand_hrs; capacity_utilisation_pct = monthly_demand_hrs / monthly_capacity_hrs * 100; capacity_surplus_deficit = monthly_capacity_hrs - monthly_demand_hrs; required_mechanic_hrs = monthly_demand_hrs; recommended_mechanics = ceil(required_mechanic_hrs / (working_hours_per_day * working_days_per_month * mechanic_efficiency_pct / 100)); external_work_required_hrs = max(0, monthly_demand_hrs - monthly_capacity_hrs)
