When you set up a fixed asset depreciation profile and select Straight line life remaining in the Method field in the Depreciation profiles form, the depreciation of fixed assets that are assigned to this depreciation profile is based on the remaining service life of the asset. This generally is the same depreciation amount 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 in the Depreciation profiles form. Depending on the selection in the Depreciation year field, the options will change in the Period frequency field.

You can select either Calendar or Fiscal in the Depreciation year field in the Depreciation profiles form. Your selection defines the options that are available in the Period frequency field. The default option is Calendar.

When you select Calendar, a year of January 1 to December 31 is assumed, even if you have defined the fiscal calendar differently.

The Calendar option updates the depreciation base, which is typically the net book value minus the salvage value, on January 1 of each year. In the example later in this topic, the depreciation base is the numerator in the first expression in the calculations column.

If you select Calendar, the following options are available in the Period frequency field, which defines the depreciation accrual posting dates and amounts throughout the calendar year:

  • 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 using one transaction for each day.

    NoteNote

    (THA) This control is available only to legal entities whose primary address is in Thailand.

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 1/12 of the yearly depreciation amount.

If you select Fiscal in the Depreciation year field, the straight line life remaining depreciation is used. It is calculated based on the fiscal years remaining.

For example, for fiscal year July 1, 2014, through June 30, 2015, 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 in the Fiscal calendars form.

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 calculated for the fiscal year as one amount on the last date of the fiscal year.

  • Fiscal period calculates the total amount of the depreciation for the fiscal year, which is accrued into the fiscal periods that are defined in the Fiscal calendars form for the fiscal calendar that is specified for the value model or depreciation book.

A fixed asset has the following characteristics.

Acquisition cost

11,000

Salvage value

1,000

Depreciation base

10,000

Service life years

5

Yearly depreciation

2,000

You get the same depreciation amount each year.

(Acquisition cost - Salvage value) / Service life years

Period

Calculation of 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
