Sum-of-the-Years' Digits (SYD) depreciation is an accelerated method of depreciation where more depreciation is claimed in the initial years of an asset's life. This is useful for assets that decline in value rapidly starting at the time of purchase, either due to technical obsolescence or useful life.
Scenario: A mid-market manufacturing company is using Excel for its financial budgeting, forecasting, and planning. The company operates machinery and tooling assets which are subject to depreciation. They are struggling to properly depreciate these assets because of the maintenance required in Excel.
Solution: They purchase CPM software that supports the Sum-of-the-Years' Digits depreciation method. The finance department can now add an asset, select SYD, and let the CPM tool run all calculations and allocate depreciation appropriately. They can also apply this to historical assets, helping them quickly move off of Excel for this function.
Like double declining balance depreciation, this is meant for assets that depreciate rapidly upfront. SYD is a slightly less aggressive depreciation method. If the CPM system offers it, try modeling the methods side by side to see which one makes the most sense in your plan.
Most CPM systems do not offer this method, as it is a bit redundant with DBD. That said, if this is crucial, as them if they can do this:
For Example:
Calculation Steps:
Straight-Line Rate = 1 / Useful Life of the Asset
Straight-Line Rate = 1 / 5 = 20%
Double Declining Rate = 2 * Straight-Line Rate = 40%
Year 1 Depreciation Expense = Double Declining Rate * Cost of the Asset
Year 1 Depreciation Expense = 40% * 10,000 =4,000
Example for the Second Year:
10,000 (initial cost) -4,000 (year 1 depreciation) = $6,000
40% * 6,000 =2,400
The calculations in this example take place in steps. For some lower-cost CPM tools, this may be difficult as their calculation engines are less mature. If this is important to you, ask to see the process work live.
