Labor Hourly Rate and Billing RateConverts gross labor through surcharges, absenteeism, and billable ratio to the cost of a productive hour and the billing rate. Unit cost and selling priceCombines material, machining and auxiliary time, setup, programming, finishing, overhead, and profit into cost and selling price per part. Quote calculationCalculates multiple line items including one-off costs, discounts, freight, and VAT.

How to use the result

The machine hourly rate excludes personnel costs. For costing, add the operator labour rate proportionally, with a lower share for multi-machine operation.

Productive hours have the greatest influence. Use actual values from production data collection rather than theoretical shift time.

Formulas
