Examples
Gross book minus the contra is leftover
You run a pizzeria. On June 18 you open the fixed-asset schedule for the dough sheeter you bought from an equipment supplier last year for $7,640. Accumulated depreciation is $2,292, so net book value is $5,348: $7,640 minus $2,292. On the balance sheet, Equipment still shows $7,640 and the contra-asset shows $2,292; gross book value is the $7,640 before that offset. Do not journal the asset line down to $5,348.
The invoice is not leftover book
You run a chocolate shop. On September 23 your insurer asks for leftover book on the used temperer you bought from an equipment dealer. You pull the original invoice of $10,875, and a dealer listing sits at $4,390, so you almost send one of those. Gross book value is $10,875 before the offset, and accumulated depreciation is $3,806, so net book value is $7,069. Send $7,069 and leave Equipment at $10,875; the listing is a market ask, not leftover book.
Why it matters
Net book value is leftover book: the recorded amount of an asset after you subtract accumulated depreciation or another valuation offset. Gross book value is the amount before that subtraction. If you have equipment, vehicles, or furniture, the leftover changes at every close as the contra-asset grows, and you look it up again when you sell, scrap, file a claim, or a lender asks what is still on the balance sheet. Treat original cost as leftover and the asset looks too large; treat a sale price or appraisal as leftover and you have swapped market for books. Keep the asset line at the recorded amount, let the contra grow, and read net book as the difference, not as a rewrite of the asset or a market quote.
