The Dive Shop page allows you to
enter the shop where you bought the item, the date it was purchased and
the rate at which you want to write it off (the Amortisation rate).
Depreciation is at a fixed rate each year, on the anniversary of the
purchase. The current value of the item is calculated from the original
price, the rate of amortisation and the number of years since the item was
bought.
Writing off a pair of fins over
five years is probably overkill, but the facility may prove useful if you
are an Equipment Officer trying to manage a dozen sets of branch diving
kit and budget for their replacement. The total current value of your
equipment also gives a minimum value for which you should insure it.
