Meaning
Accounting method for depreciating capital equipment allocates the cost of a machine based on its actual usage rather than the passage of time. Machine hour amortization links the expense of an asset directly to the volume of work it performs throughout its operational life. It provides a more accurate match between revenue and expenses for factories where production levels vary significantly from month to month.
The process concludes when the total number of estimated working hours is reached or the salvage value is all that remains.
Operational Accuracy
Financial statements under this system better show the wear and tear on heavy machinery used in manufacturing. During periods of low demand, the depreciation expense recorded on the balance sheet is lower. This prevents an artificial reduction in profits when the equipment is sitting idle and not generating income.
Precise tracking of these hours ensures that the book value of the facility remains consistent with its physical capacity.
Pricing Strategy
Calculating the cost per hour of operation allows a business to build precise maintenance and replacement costs into their wholesale prices. Every hour a lathe or press runs adds a specific amount to the cost of the goods produced.
Useful Life
Estimates for the total capacity of a machine are usually provided by the manufacturer or determined through historical performance data. If a machine is pushed beyond its rated speeds, the actual hours of service might be fewer than the original projection. Periodic audits of the hour meters ensure that the remaining book value of the asset stays aligned with its physical condition.
