How to calculate furniture depreciation depends upon the type of furniture. Mass-produced modern furniture is worth one-tenth of its purchase price the moment it leaves the store. Further devaluation is dependent upon wear and tear. Such furniture regains value only if kept in pristine condition for decades. For example, mass-produced furniture from the 1930s-1970s is valued today by
. collectors, but must be in like-new condition. The only furniture guaranteed to maintain most of its purchase price value is antique furniture, which is why many homeowners view their antiques as investments rather than regular purchases. A Tiffany lamp purchased today at an antique store is likely to worth as much, if not more, than its purchase price two years later (provided that it remains in the same condition).
