Unformatted text preview: hrough the “DDB” formula found in the financial category.
The formula requires asset cost, asset salvage or residual value, life, period of life, and depreciation
factor. Excel expects the number 2 or the percentage 200% to represent doubledeclining depreciation.
Depreciation at 150% declining balance would be input as 1.5 or 150%. Excel will accept and work with
any schedule entered in these formats.
The “Declining Balance” worksheet in the “Depreciation” data file shows the formula in action with
the same basic values as utilized for the straightline depreciation above. The “Declining Balance”
worksheet looks to the “Input” worksheet for values and factors. The “DDB” or double declining balance
formula requires the cost of the asset, the salvage value, the life, the period depreciation is asked for, and
the factor. Even though the title of this formula is “DDB” indicating double declining balance, it will
accept any logical factor you input. In cell B12 the formula reads “=IF(A12="","",DDB($B$2,$B$4,
$B$5,A12,$B$7)).” The “If” statement checks for available depreciation as explained in the
“StraightLine Depreciation” section. It then looks to cells B2 through B7 for cost, salvage value, and the
declining factor. The factor will default to 2, (200%) if left blank. Since declining balance depreciation is
sensitive to the period for valuation, the “A12” reference provides the period reference.
Clue: Utilizing the DDB formula may require an adjustment at the end of the life of the asset to get
the asset to fully depreciated amount of “0”. The table below shows doubledeclining depreciation by
“Pencil and paper” without salvage value and no adjustment. If the adjustment is held until the last period
of a 5year life, the last year’s depreciation is actually $12,960 while the fourth year’s depreciation
expense is only $8,640. This type of adjustment is not uncommon with accelerated deprecation schedules. Page 90 Solving Accounting Principles Problems Using Excel for Windows
The “VDB”, or “Variable Declining Balance”, concept partially addresses this situation as it is
capable of converting to straight...
