The workload method is a method of calculating the amount of depreciation payable per period based on the actual workload. This approach assumes that the value of a fixed asset wears out with the degree of use, so the original cost of the fixed asset should be evenly distributed among the workloads provided by the fixed asset. This method calculates the depreciation per unit of work to be equal.In the workload method, the workload can be mileage, hours worked or product output.
