Straight line life remaining depreciation
This article gives an overview of the Straight line life remaining method of depreciation.
When you set up a fixed asset depreciation profile and select Straight line life remaining in the Method field on the Depreciation profiles page, the depreciation of fixed assets that are assigned to the depreciation profile is based on the remaining service life of the asset. The depreciation amount is generally the same in each depreciation period. To set up straight line life remaining depreciation, you also must select options in the Depreciation year field and the Period frequency field on the Depreciation profiles page. The options that are available in the Period frequency field vary, depending on the value that is selected in the Depreciation year field.
Select a depreciation year
You can select either Calendar or Fiscal in the Depreciation year field on the Depreciation profiles page. The default value is Calendar. Your selection determines the options that are available in the Period frequency field. This field defines the depreciation accrual posting dates and amounts throughout the calendar year.
If you select Calendar in the Depreciation year field, a year of January 1 through December 31 is assumed, even if you've defined the fiscal calendar differently. The Calendar option updates the depreciation base on January 1 of each year. Typically, the depreciation base is the net book value minus the salvage value. In the example later in this article, the depreciation base is the numerator in the first expression in the calculations column. If you select Calendar as the depreciation year, the following options are available in the Period frequency field:
- Yearly posts an amount on December 31.
- Monthly posts a monthly amount at the end of each calendar month.
- Quarterly posts a quarterly amount at the end of each calendar quarter (March 31, June 30, September 30, and December 31).
- Half-Yearly posts a half-yearly amount at the end of each calendar half year (June 30 and December 31).
- Daily posts the depreciation amount for the daily depreciation method by using one transaction for each day.
For example, if you select Yearly, the yearly depreciation is posted only one time, on December 31 of each year. If you select Monthly, the monthly depreciation is posted each month, as one-twelfth of the yearly depreciation amount.
If you select Fiscal in the Depreciation year field, straight line life remaining depreciation is used. Depreciation is calculated based on the fiscal years remaining. For example, for the fiscal year July 1, 2015, through June 30, 2016, the depreciation calculation starts on July 1. The fiscal year can be longer or shorter than 12 months. The depreciation is adjusted for each fiscal period. The length of the next fiscal year is determined by the fiscal periods that are set up on the Fiscal calendars page. If you select Fiscal as the depreciation year, the following options are available in the Period frequency field:
- Yearly posts the total amount of the depreciation that is calculated for the fiscal year as one amount, on the last day of the fiscal year.
- Fiscal period calculates the total amount of the depreciation for the fiscal year. This amount is then accrued into the fiscal periods that are defined on the Fiscal calendars page for the fiscal calendar that is specified for the book.
Example of straight line depreciation of an unchanged fixed asset
A fixed asset has the following characteristics.
|Service life years||5|
The depreciation amount is the same every year: (Acquisition cost – Salvage value) ÷ Service life years
|Period||Calculation of the yearly depreciation amount||Net book value at the end of the year|
|Year 1||(11,000 – 1,000) ÷ 5 = 2,000||9,000|
|Year 2||(9,000 – 1,000) ÷ 4 = 2,000||7,000|
|Year 3||(7,000 – 1,000) ÷ 3 = 2,000||5,000|
|Year 4||(5,000 – 1,000) ÷ 2 = 2,000||3,000|
|Year 5||(3,000 – 1,000) ÷ 1 = 2,000||1,000|
