Do I multiply hours by the operator count?

Sum each operator’s actual time. Three operators working one hour each contribute three person-hours, even though only one clock hour elapsed.

What if an operator serves two mixers?

Enter only time assigned to this batch as direct hours. The paid-hour record can cover both mixers, but the same time cannot be assigned twice.

What belongs in the indirect labor amount?

Enter supervision or support labor allocated separately to this batch. Exclude costs already included in the loaded direct labor rate.

Why enter paid hours?

Paid hours disclose the direct charge share and prevent assigning more time than the record contains. They do not add a second labor charge.

Labor per Batch Calculator

Find the labor cost assigned to one mixing batch. Use its time tickets, the corresponding paid-hour record, loaded rate, indirect allocation and labor budget.

What this calculator does

Calculate the labor cost assigned to a batch from recorded direct hours, loaded payroll rate and indirect labor allocation.

Formula used

Direct labor cost = direct person-hours × loaded rate
Batch labor cost = direct labor cost + indirect allocation
Direct charge share = direct hours ÷ paid hours × 100
Budget headroom = labor budget − batch labor cost

Inputs explained

Direct Batch Labor Time: Batch time tickets summed across the assigned operators.
Paid Allocation-Period Labor Time: Paid person-hours in the same operator allocation record.
Loaded Direct Labor Rate: Payroll rate including benefits but excluding the indirect allocation.
Allocated Indirect Labor Cost: Supervision and support labor charged separately to this batch.
Batch Labor Budget: Approved labor allowance for the batch.

How to use the result

Best suited to shared operator allocation, batch labor reconciliation.
Does not schedule operators or estimate unattended mixer time.
