When you set up a fixed asset depreciation profile and select Reducing balance in the Method field in the Depreciation profiles form, the assets that have this depreciation profile assigned to them are depreciated by the same percentage in each depreciation period.
To set up reducing balance depreciation, you must also make selections in fields on the General FastTab of the Depreciation profiles form. First, select a year in the Depreciation year field. Depending on the selection, different options appear in the Period frequency field, as explained in the following sections.
You must also enter a value in the Percentage field for the depreciation profile. If you select the Full depreciation check box, the remaining depreciation basis is taken in the last depreciation period and could be a large amount. Some countries/regions do not use a switchover to a straight line method. Switchover occurs when the alternative depreciation method amount is greater than or equal to the primary depreciation profile amount, and the depreciation amount taken is the alternative method amount.
Because an asset will never be fully depreciated based on a percentage calculation, you must select the Full depreciation check box to fully depreciate an asset.
You can select either Calendar or Fiscal in the Depreciation year field in the Depreciation profiles form. The selection defines the options that are available in the Period frequency field. The default option is Calendar.
The Calendar option updates the depreciation base, which is typically the net book value minus the scrap value, on January 1 of each year. In the reducing balance depreciation 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 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.
(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 depreciation method is used. It is calculated based on the fiscal year, which is set up in the Fiscal calendars form for the fiscal calendar that is selected in the Ledger form.
For example, for fiscal year July 1 through June 30, 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 based on the fiscal periods that you set up when you create a new fiscal year in the Fiscal calendars form.
You can select a fiscal calendar for a value model in the Value models form. For more information, see Value models setup (form). You can select a fiscal calendar for a depreciation book in the Depreciation books form. For more information, see Depreciation books setup (form).
If you select Fiscal, 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 day of the fiscal year.
Fiscal period posts the total amount of the depreciation calculated for the fiscal year, which is accrued into the fiscal periods that are defined for the fiscal calendar that is selected in the Ledger form, or for the fiscal calendar that is selected for the value model or depreciation book for a fixed asset.
Suppose that the fixed asset acquisition price is 11,000, the scrap value is 1,000, and the depreciation percentage factor is 30.
Using the Reducing balance method, 30 percent of the depreciation base (net book value minus scrap value) is calculated at the end of the previous depreciation period. Depreciation for the first three years is shown in the following table.
Calculation of yearly depreciation amount
Net book value at the end of the year
(11,000 - 1,000) * 30% = 3,000
(11,000 - 1,000) - 3,000 = 7,000
(7,000 - 1,000) * 30% = 1,800
(7,000 -1,800) = 5,200
(5,200 - 1,000) * 30% = 1,260
(5,200 - 1,260) = 3,940
The depreciation rates for Germany are calculated as follows:
If triple the depreciation rate of the straight line method is less than the given maximum percentage for the reducing balance, triple the straight line rate must be used for calculating the depreciation amount.
If triple the depreciation rate of the straight line method is greater than the given maximum percentage for the reducing balance, this given percentage must be used for calculating the depreciation amount.
