Some are associated with a given legislation, while others are common to all legislations.
This document describes the calculation principles of the depreciation methods associated with the American legislation.
The other methods are described in appendix documentations, which can be accessed from the documentation on the depreciation methods common to all legislations.
This straight-line depreciation method is used in the United Kingdom and the United States.
It is dependent on the type of prorata temporis specified by the user in the depreciation plan:
(1) Regardless of the day of the depreciation start date.
(1) Regardless of the day of the depreciation start date, even if it is the 1st day of the month.
(1) Regardless of the day of the depreciation start date, even if it is the 1st day of the quarter.
(1) Regardless of the day of the depreciation start date and regardless of the fiscal year duration.
The duration is expressed in years and hundredths of years.
The depreciation rate cannot be entered by the user. It is automatically calculated, as follows: 1 / duration
It depends on the prorata temporis type:
+ (Depreciation duration – 0,5)
The result is the last day of a month.
Examples of calculation of depreciation end dates:
Start date | Duration | End date |
01/01/2005 | 3 years and ½ year | 30/06/2008 |
14/10/2005 | 3.25 and ½ year | 30/09/2008 |
01/01/2005 | 5.33 and Month | 30/04/2010 |
01/01/2005 | 3 and ½ month | 15/01/2008 |
08/11/2005 | 3.25 and ½ month | 15/02/2009 |
01/01/2005 | 3 and ½ quarter | 15/02/2008 |
08/12/2005 | 3 and ½ quarter | 15/11/2008 |
The type of prorata temporis can be specified by the user or defined by the associations if the depreciation method is itself defined by the associations. It can be modified via the Method change action.
The possible values are the following:
The charge is equal to:
Depreciable value * Depreciation rate * prorata temporis (1)
Notes:
(1) The prorata temporis is expressed either in: ½ year, month, ½ month, or ½ quarter.
- Depreciable value = (Gross value – Residual value)
- If the Depreciation end date is equal to the Fiscal year end date and if the asset is not issued before this depreciation end date, then the Fiscal year charge = Net depreciable value.
- If the Net depreciable value is larger than 0, and the residual depreciation duration is equal to 0 (case where Depreciation end date < Fiscal year start date), then Fiscal year charge = Net depreciable value so as to close the depreciation.
The charge of the disinvestment fiscal year is calculated based on the type of prorata temporis:
If the fiscal year is divided into several periods, the fiscal year charge is distributed over these periods. The distribution rule differs according to the prorata temporis applied:
p1 to pc = from the 1st holding period in the fiscal year to the current period included (1)
p1 to pf = from the 1st holding period in the fiscal year to the last holding period in the fiscal year
(1) Unless the asset is issued in the fiscal year before this current period or if it is completely depreciated in the fiscal year before this current period. The period retained is thus the minimum period among the 3 following ones:
- period of depreciation end if the Depreciation end date belongs to the interval [period start – period end]
- disposal period if the Disposal date belongs to the interval [period start – period end]
- current period
For this depreciation method, the period weight is not taken into account.
If a method change occurs during a fiscal year that is later than the acquisition fiscal year, or if there is a revaluation of the Depreciable value, or a depreciation is recorded:
- the depreciation method is changed from Straight line to Residual,
- apart from the depreciation that triggers the revision of the plan at the start of the next period, the other actions (method change, actualization of depreciation basis, revaluation) trigger a revision of the plan at the start of the current period.
The fiscal year charge is thus equal to:
Depreciation total of the closed periods
+
"Residual" charge of the fiscal year calculated after the revision of the plan

This declining depreciation method is used in the United Kingdom and the United States.
It is dependent on the type of prorata temporis specified by the user in the depreciation plan:
(1) Regardless of the day of the depreciation start date.
(1) Regardless of the day of the depreciation start date, even if it is the 1st day of the month.
(1) Regardless of the day of the depreciation start date, even if it is the 1st day of the quarter.
(1) Regardless of the day of the depreciation start date and regardless of the fiscal year duration.
The duration is expressed in years and hundredths of years.
Examples:
The depreciation rate cannot be entered by the user. It is automatically calculated according to an acceleration coefficient, as follows:
( 1 / duration ) * acceleration coefficient
This acceleration coefficient must be specified by the user or defined by the associations (for instance if this method is itself defined by the associations). It can be modified via the Method change action.
It corresponds to the digressivity factor which is applied for the French declining depreciation method. It can be equal to:
- 1.25
- 1.50
- 1.75
- 2
It depends on the prorata temporis type:
+ (Depreciation duration – 0,5)
Calculation examples of depreciation end dates:
Start date | Duration | End date |
01/01/2005 | 3 years and ½ year | 30/06/2008 |
14/10/2005 | 3.25 and ½ year | 30/09/2008 |
01/01/2005 | 5.33 and Month | 30/04/2010 |
01/01/2005 | 3 and ½ month | 15/01/2008 |
08/11/2005 | 3.25 and ½ month | 15/02/2009 |
01/01/2005 | 3 et ½ trimestre | 15/02/2008 |
08/12/2005 | 3 et ½ trimestre | 15/11/2008 |
The type of prorata temporis can be specified by the user or defined by the associations if the depreciation method is itself defined by the associations. It can be modified via the Method change action.
The possible values are the following:
The charge is equal to the largest of the 2 following values:
Notes:
- Net depreciable value = (Net value – Residual value)
- Residual depreciation duration = length of the interval [fiscal year start date - fiscal year end date]
- If the Depreciation end date is equal to the Fiscal year end date and if the asset is not issued before this depreciation end date, then the Fiscal year charge = Net depreciable value.
- If the Net depreciable value is larger than 0, and the residual depreciation duration is equal to 0 (case where Depreciation end date < Fiscal year start date), then Fiscal year charge = Net depreciable value so as to close the depreciation.
The charge of the disinvestment fiscal year is calculated based on the type of prorata temporis:
If the method is changed during the fiscal year (revision of the duration, the acceleration coefficient, the prorata type, or the depreciation start date), the change is systematically effective at fiscal year start: the fiscal year charge is therefore re-calculated with the new method.
If the fiscal year is divided into several periods, the fiscal year charge is distributed over these periods. This distribution is applied according to the following rule:
p1 to pc = from the 1st holding period in the fiscal year to the current period included (1)
p1 to pf = from the 1st holding period in the fiscal year to the last holding period in the fiscal year
(1) Unless the asset is issued in the fiscal year before this current period or if it is completely depreciated in the fiscal year before this current period. The period retained is thus the minimum period among the 3 following ones:
- period of depreciation end if the Depreciation end date belongs to the interval [period start – period end]
- disposal period if the Disposal date belongs to the interval [period start – period end]
- current period
For this depreciation method, the period weight is not taken into account.
The Depreciation end date determined by Sage X3 is: 30/06/2011

(5) 1,728.00 * 12 / 18 = 1,152.00 since > than 1,728.00 * 40% = 691,20
(6) 576.00 * 6 / 6 = 576.00
If this asset is issued in 2010, regardless of the disposal date:
Fiscal year | Net depreciable value | Fiscal year charge | Fiscal year total |
01/01/2010 – 31/12/2010 | 1,728.00 | (7) 576.00 | 8,848.00 |
(7) 1,728.00 * 12 / 18 = 1,152.00 * 50% or 6/12 = 576.00 (50% or 6/12 since a ½ charge for the disposal fiscal year).
If this asset is issued in 2011, regardless of the disposal date:
Fiscal year | Net depreciable value | Fiscal year charge | Fiscal year total |
01/01/2011 – 31/12/2011 | 576 ,00 | (7) 288.00 | 9,712.00 |
(7) 576.00 * 6 / 6 = 576.00 * 50% = 288.00 (50% since a ½ charge for the disposal fiscal year)

(5) 576.00 * 6/6 = 576.00 – 288.00 = 288.00
If the fiscal year had been divided into months (monthly stops), the distribution of the fiscal year charge would have been done in the same manner, that is, by applying a holding prorata in months. The 1st charge would therefore have been recorded in 04/2006.

If the fiscal year had been divided into months (monthly stops), the distribution of the fiscal year charge would have been done in the same manner, that is, by applying a holding prorata in ½ months:
The Depreciation end date determined by Sage X3 is: 15/04/2009

01/01/2008 – 31/12/2008 | 3,229.16 | (5) 520.83 | 7,291.67 |
(5) 3,229.16 * 5/31 = 520.83 (5/31 = 5 ½ holding months in 2008)
If this asset has been issued on 7/14/2009:
Fiscal year | Net depreciable value | Fiscal year charge | Fiscal year total |
01/01/2009 – 31/12/2009 | 729.17 | (6) 729.17 | 10,000.00 |
(6) Disposal date 14/07/2009 > Depreciation end date 15/04/2009. Therefore there is no prorata temporis to apply due to the disposal.
