skelet666 [1.2K]

Answer:

$339

Step-by-step explanation:

Calculation for the amount of Depreciation that Calvin may claim 2018 Using the half-year convention

Based on the information given we were told that he purchased a new office desk at the amount of $2,373 which means that the new office desk using the half-year convention will be a 7 year property.

Hence,

The Standard Depreciation percentage of the new office desk which is a 7 year property is 14.29% based on this the amount of Depreciation that Calvin may claim 2018 Using the half-year convention will be calculated as:

Using this formula

Depreciation=Cost of new office desk* New office Desk Depreciation percentage

Let plug in the formula

Depreciation=$2,373*14.29%

Depreciation=$339

Therefore Using the half-year convention Calvin may claim 2018 depreciation in the amount of $339
