gain or loss on disposal

When you finally sell an old work asset, there is a natural question: did I come out ahead or behind compared with what my records said it was worth? If you sell a van for more than its value on your books, that is a happy surprise — a gain. If you have to let it go for less, that is a shortfall — a loss. The gain or loss on disposal is simply the scorecard for that moment, comparing what you got against what the asset was carried at.

Gain or loss on disposal is the difference between the proceeds received when an asset is disposed of and its book value (cost minus accumulated depreciation) at the date of disposal. If proceeds exceed book value, there is a gain; if proceeds fall short, there is a loss; if they match, neither. For example, an asset with a book value of 6,000 sold for 9,000 produces a 3,000 gain; sold for 4,000, it produces a 2,000 loss. The crucial subtlety: the gain or loss is measured against book value, not against the original cost — a machine bought for 50,000 but depreciated down to 6,000 and sold for 9,000 still shows a 3,000 gain, not a loss, even though you sold it for less than you paid.

These gains and losses matter because they land on the income statement, usually as non-operating items, and they reveal something honest: a gain often means the asset was depreciated too aggressively (its life was underestimated), while a loss can mean depreciation was too slow. They are not part of normal operating profit, so analysts strip them out when judging core performance. The frequent trap is comparing the sale price to what was originally paid; accounting only ever cares about the comparison to current book value.
