Examples
A territory license still shows leftover cost
On February 3, 2024, your tutoring business paid a curriculum licensor $18,000 for a five-year territory license and booked it as an intangible asset. At the October 31, 2025 close you have posted 21 months of $300 amortization, so $6,300 has been written off. Amortized cost is $11,700: the $18,000 cost less those portions. The license still sits at $18,000 on the balance sheet; accumulated amortization is the $6,300 contra. In QuickBooks Online or Xero, do not journal the asset down to $11,700; read leftover as cost minus write-offs.
The leftover loan is not leftover cost
You run a sauna studio. In July, the credit union asks for the amortized cost of the eight-person barrel sauna you bought from a sauna manufacturer for $9,600. You still owe $4,200 on that shop loan, so you almost send $4,200, but that is remaining principal, not cost less portions written off. Open the fixed-asset schedule: original cost is $9,600 and accumulated depreciation is $2,880, so amortized cost is $6,720. Send $6,720 and keep the loan on the liability side.
Why it matters
Amortized cost is the leftover book amount: original cost minus the portions already written off. If you keep equipment, vehicles, or other items you write off over time, this leftover moves at every close when you take that period's amortization or depreciation, and again when you sell, scrap, or check remaining value on the balance sheet. Leave the purchase price as the remaining figure and value looks too high; treat this month's write-off as the leftover and the asset looks nearly gone. Do not swap it for a remaining loan balance, that is debt, or for a current asking price, that is market, not cost less write-offs.
