Examples
Cost minus timber depletion is leftover book
You run a sawmill. On April 8, 2019 you bought a 40-acre timber tract from a land company for $86,000 and booked it as a timber property. At the December 31, 2025 close, the asset schedule shows $52,400 of accrued depletion. Depleted cost is $33,600: residual cost after deducting that accrued depletion. On the balance sheet the tract still sits at $86,000 with a $52,400 contra; you do not journal the asset down to $33,600. If you quote $86,000 as leftover book, you handed over original cost, not depleted cost.
This year's charge is not leftover book
You run a small limestone quarry. In March your CPA asks for depleted cost of the quarry lease you bought from a mineral company. You almost send this year's depletion from the P&L, $8,200, because that is the charge you just posted. That figure is the period's exhaustion, not leftover book. Open the general ledger or the asset schedule: cost is $140,000 and accrued depletion is $61,500, so depleted cost is $78,500. Send $78,500. If you treat $8,200 as depleted cost, you swapped the periodic charge for the residual.
Why it matters
Depleted cost is leftover book on a mineral, coal, oil, natural-gas, or timber property: what you paid minus depletion already taken. Most US small businesses never see this unless they own those rights. When you do, the leftover moves after each depletion charge and again when you sell the property or borrow against it. Treat this period's depletion as the leftover and the property looks nearly gone; leave original cost as leftover and the asset looks too large. Do not apply this to a delivery van or shop equipment. That leftover is cost minus depreciation, not depletion.
