- Units of Production: To calculate depreciation amounts proportionally to actual usage of the fixed asset. If salvage value is greater than zero, depreciation stops when the net book value becomes equal or less than the salvage value.
The Useful Life (Months) column subcolumn (available for the the Straight Line method) is populated with the number of months the fixed asset was initially was planned to be usedfor use.
