DB

Returns the depreciation of an asset for a given year using the fixed rate declining-balance method.

Syntax:

DB(originalcost; salvagevalue; lifetime; year; months1styear)

originalcost: the initial cost of the asset.
salvagevalue: is the value at the end of the depreciation (sometimes called the salvage value of the asset).
lifetime: the number of years over which the asset is being depreciated.
year: the year number for which the depreciation is calculated.
months1styear: the number of months in the first year (defaults to 12 if omitted).
To calculate depreciation, DB uses a fixed rate throughout the asset’s life, given by
rate = 1 - (salvagevalue/originalcost)(1/lifetime)
rounded to 3 decimal places.
The depreciation in any year is given by
value_at_start_of_year * rate
where value_at_start_of_year = originalcost - depreciation_so_far.
If months1styear is less than 12 the depreciation rate used for the first and last years is
rate * number_of_months_in_year / 12.

Example:

DB(10000; 1000; 5; 1)

returns approximately 3690 in currency units, which is the depreciation in the first year for an asset which cost 10000 and is written down to 1000 over 5 years.

Issues:

  • This method underestimates total depreciation slightly if months1styear is given and not 12.
