指资本资产在卖出或准备卖出时的单价差于最初买入时的单价而造成的损失。资本损失与资本收益的概念相对。
The loss incurred when a capital asset (investment or real estate) decreases in value. This loss is not realized until the asset is sold for a price that is lower than the original purchase price.
A capital loss is essentially the difference between the purchase price and the price at which the asset is sold, where the sale price is lower than the purchase price.For example, if an investor bought a house for $250,000 and sold the house five years later for $200,000, the investor would realize a capital loss of $50,000.
