Factory overhead/Machine hours . If factory overhead is Rs 3, 00,000 and total machine hours are 1,500, the machine hour rate is Rs 200 per machine hour (Rs 3, 00,000 ÷ 1500 hours). Advantages: This method can be used advantageously where the machine
Dec 13, 2016 So if you’re used to milling for 30 minutes an hour at 110 fpm, and sitting the rest of the hour, you could slow down to 80-90 fpm and cut for 45 minutes out of the hour
Calculate the annual costs of these, then divide by total labor or machine hours for the year. This will be your overhead cost per hour Once the above costs are calculated you can use the formulas and guidelines below to arrive at either a “general” shop hourly rate or an hourly rate based on a specific piece of equipment.
