The electricity price times the nominal power of the machine would create the cost for power, but as the power usage is not constant as cooling off periods or manual operations or whatnot occurs a power conversion factor is used. This factor is an estimate of between 50-70% of the energy that would have been used under constant load.
Machine maintenance if unknown can be estimated to 2-5% of the investment cost, if information is available regarding scheduled maintenance hours and costs associated a machine maintenance cost per hour can be produced by dividing the product with the amount of yearly production hours. Note that only one of these options should be used, as otherwise it will be counted two times.
Spare parts and tooling maintenance is most often included in the part price in the form of a overhead, if it is not the model has support for calculating these costs.
Variable cost per hour is based on consumables per hour, tool maintenance cost per hour, energy price per hour and maintenance cost per hour.
Direct manpower together with the direct labour rate decided in the overhead section makes up the manpower cost per hour.
Machine cost per hour comes from variable costs per hour, fixed costs per hour and production overhead per hour.
Manpower + Machine cost per hour is the direct manpower cost per hour and machine cost per hour combined. Often this is the rate that can be compared to the hourly rate given in the RFQ from suppliers.
The set up cost is based on manpower + machine cost per hour as the machine is active although no value is being produced.
