The depreciation rate will grow to 50 percent for the period before the last period and grows to 100 percent for the last period.


The prorated depreciation is taken into account if an asset is purchased in the middle of the accounting period.

Keep in mind to use the DATE function if you enter dates in the function instead of using cell references.

For example,

=AMORLINC(C2, DATE(2018,9,21), DATE(2018,12,31),C5,C6,C7,C8)
