Do two technicians double the outage duration?

No. Their person-hours add, but simultaneous work may finish in the same elapsed time.

Where should lockout preparation appear?

Enter its total person-hours as shared preparation if those hours are excluded from the repeated task time.

Can different technicians have different rates?

Use a documented weighted average only when its hour basis matches this task, or price each trade separately.

Are spare parts included in this total?

No. This task estimate covers labor and separate support charges; maintain replacement parts in the wider maintenance budget.

Maintenance & Reliability calculator

PM Labor and Support Cost Calculator

Estimate labor and separate support costs for one preventive task. Enter technician count, hours per technician, the loaded rate and shared preparation labor.

What this calculator does

Price preventive task labor from assigned technicians, measured hours and a documented loaded rate.

Formula used

Task person-hours = technicians × task hours per technician
Total labor = task person-hours + shared preparation person-hours
Direct task labor = task person-hours × loaded labor rate
Preparation labor = preparation person-hours × loaded labor rate
Total task cost = direct task labor + preparation labor + separate support charges

Inputs explained

Assigned Technicians: Technicians assigned to the repeated task work.
Task Time per Technician: Hands-on task hours assigned to each technician.
Loaded Labor Rate: Approved hourly labor rate with its documented overhead scope.
Shared Preparation Labor: Total staging and access labor outside the repeated task hours.
Separate Support Charges: Permits, rentals and support charges excluded from loaded labor.

How to use the result

Best suited to preventive work-order estimate, crew assignment comparison.
Different trades or overtime rates need separate work-order estimates. This model excludes production loss and replacement parts.

Current U.S. benchmarks

U.S. manufacturing runs at 75.7% of capacity (Federal Reserve, Aug 2026). New factory orders are up 8.5% year over year (Census).
