Wood Flooring Home Office Depreciation

I put wood flooring in my home office ONLY.  The cost of the flooring was 1700.00.  I am doing the labor myself.  When I went to add the flooring as a business home office asset, it figured depreciation at 13.00!  I am curious why it would be this low?  Shouldn't it depreciate the entire 1700.00?  At 13.00 a year, it is only depreciating 390.00. 

HELP.
