Use this Service Inventory Calculator to treat time, staff capacity, and booking slots as service inventory. It estimates total capacity, remaining slots, utilization rate, and burnout risk so service businesses can balance sales and delivery.
Enter available service hours, average hours per service, booked services, and target utilization. The calculator estimates capacity, remaining slots, and utilization.
Use it to avoid underbooking, overbooking, and delivery burnout.
In service businesses, time and staff availability act like inventory. Low utilization means unused capacity, while excessive utilization can damage service quality.
A utilization rate near 100% may look good financially but can create delays, burnout, and quality problems.
If 400 hours are available and each service takes 4 hours, capacity is 100 services. With 75 booked services, utilization is 75% and 25 slots remain.
A utilization rate around 70% to 85% is often healthy because it balances revenue, quality, and flexibility.
Divide available service hours by the average number of hours required per service.
Estimate monthly capacity by dividing available delivery hours by hours required per client or service.
Avoid sustained utilization above 90%, protect buffer time, and monitor workload quality indicators.
Improve scheduling, reduce cancellations, package services, and fill unused capacity with recurring clients.
