The real costs of a machine over time follow typical curves. These are important for interim costing and the use of depreciated old machines.
Until now, we only looked at the costs of one sub-system. to get the total costs, may we simply add the costs of the subsystems?
And we get to know a star under the working machines: the written-off machine. You will get an idea how to calculate the costs of this Methusalem and where it will be wise to use it.
