How the labor charge is calculated
Example：2.4 h × 30,000 yen/h ＝ 72,000 yen
These figures are an example to explain the calculation only. Actual repair costs also include parts, paint materials and subcontracting.
ZENDAIKYO does not set or recommend any labor rate amount. Each business decides its own rate based on its own costs.
How much does it cost when the kosu changes?
Labor charge ＝ Kosu (work hours) × Labor rate
How a shop works out its labor rate
The basic approach is to take the cost of running the shop for one year (staff, equipment, buildings, overheads and so on) plus a reasonable profit, and divide it by the number of hours of work in a year that turn into sales.
Labor rate = (annual operating cost + reasonable profit) ÷ annual billable work hours
Why heavy vehicle shops are different
Repairing heavy vehicles requires frame straightening machines, large paint booths, cranes, large workshops and highly skilled technicians. These investments lie behind the rate.
The link with efficiency
With the same costs, fewer billable hours mean a higher labor rate. Process management and efficiency are the foundation of a fair rate.
