Net fixed assets is the book value of a company’s long-term physical property after subtracting every dollar of depreciation recorded against it. The formula is simple: gross fixed assets minus accumulated depreciation. That figure shows up on the balance sheet under a line usually labeled “Property, Plant, and Equipment, Net,” and it tells you how much of the original cost of the company’s buildings, machines, vehicles, and equipment has not yet been written off as an expense. The calculation itself is subtraction. The interesting part is what sits inside each of the two numbers you’re subtracting.
The Formula
Net Fixed Assets = Gross Fixed Assets − Accumulated Depreciation
A manufacturer buys a piece of equipment for $500,000 and expects to sell it a decade later for $50,000. Using straight-line depreciation, the company records $45,000 of depreciation expense every year. After four years, accumulated depreciation on that machine has climbed to $180,000. The net fixed asset value of the equipment is $320,000, the original cost minus everything depreciated so far. That $320,000 is the portion of the cost still waiting to be matched against future revenue.
Land is the exception. It never depreciates, so its net value on the balance sheet always equals its original cost. When a company’s net fixed asset total includes land, that land sits inside the figure at full gross value while every other asset in the group has been reduced by its accumulated depreciation.
Gross Fixed Assets
Gross fixed assets is the total original cost of every long-term tangible resource the company has capitalized. Capitalizing just means the purchase went onto the balance sheet as an asset rather than straight to the income statement as an expense. The gross figure covers more than the sticker price. Freight, installation, and any other spending needed to get the asset ready for its intended use all get folded in.
The usual contents are manufacturing equipment, buildings, vehicles, furniture, specialized tooling, and land. Once an asset is recorded, its gross cost stays constant on the books until the company sells it, retires it, or records an impairment charge against it. Depreciation does not touch the gross number. It only builds up in a separate account alongside it.
Accumulated Depreciation
Accumulated depreciation is the running total of all depreciation expense charged against the company’s fixed assets since they were placed in service. Each period, a portion of an asset’s original cost moves from the balance sheet to the income statement as depreciation expense. That annual charge reduces reported profit but no cash leaves the business, which is why depreciation gets added back when calculating cash flow.
The reasoning behind the whole exercise is the matching principle. If a machine helps earn revenue over ten years, its cost should be spread across those same ten years instead of landing on the books all at once. Depreciation keeps running each period until the asset’s book value drops to its estimated salvage value, meaning the amount the company expects to recover when it eventually disposes of the asset.
Depreciation Methods
The method chosen controls how quickly the accumulated depreciation account grows, which in turn controls how quickly net fixed assets shrinks. Three approaches cover almost all book depreciation:
- Straight-line is the simplest and most common. Cost minus salvage value, divided by useful life. A $100,000 machine with a $10,000 salvage value and a 10-year life depreciates $9,000 each year, every year.
- Declining balance is accelerated. The double-declining-balance version applies twice the straight-line rate to the asset’s remaining book value each period, producing a big expense early and a smaller one later. Companies pick it for assets that lose productive value quickly.
- Units of production ties depreciation to actual use. A delivery truck depreciated per mile driven shows a heavy charge in busy years and a light one when it sits idle. This fits assets where physical wear, not obsolescence, drives the decline.
For financial reporting under GAAP, management picks the method that best reflects how the asset delivers economic value. For tax purposes, the IRS makes most of that choice for the company.
Tax Depreciation vs. Book Depreciation
Every company that owns fixed assets keeps two depreciation schedules in parallel, and the two almost never match. The book schedule follows GAAP, uses management’s own useful life and salvage value estimates, and picks a method that fits the asset. The tax schedule follows the Modified Accelerated Cost Recovery System (MACRS), where the IRS dictates the recovery period, specifies the method, and generally ignores salvage value.
Under MACRS, assets fall into classes with set recovery periods: five years for cars, trucks, computers, and research equipment; seven years for office furniture and most property without an assigned class life; fifteen years for land improvements like fences and sidewalks; 27.5 years for residential rental property; and 39 years for nonresidential commercial buildings. Most personal property depreciates under the 200% declining balance method, switching to straight-line when that produces a larger deduction. Real property runs straight-line across its full recovery period.1Internal Revenue Service. Publication 946 – How To Depreciate Property
The net fixed asset figure investors see on the balance sheet comes from the book schedule, not the tax schedule. The gap between the two schedules creates a deferred tax liability (or asset) that shows up on a separate line of the balance sheet. If anyone cites an NFA number to you, knowing which schedule produced it changes what the number means.
Section 179 and Bonus Depreciation
Two provisions of the tax code can drive an asset’s tax-basis net value close to zero almost the moment it’s placed in service, which widens the gap between book NFA and tax NFA dramatically.
Section 179 lets a business elect to deduct the full purchase price of qualifying tangible property in the year it enters service, up to an annual cap that adjusts for inflation.2Office of the Law Revision Counsel. 26 U.S. Code 179 – Election To Expense Certain Depreciable Business Assets For 2026, the cap is $2,560,000, with a phaseout that begins once total qualifying property placed in service during the year exceeds $4,090,000. The election covers equipment, machinery, certain building improvements, and off-the-shelf software, among other items.
Bonus depreciation under Section 168(k) had been phasing down from 100% toward zero, losing 20 percentage points a year. Legislation signed in early 2025 reversed that phasedown and permanently restored 100% bonus depreciation for qualifying property acquired after January 19, 2025.3Internal Revenue Service. Notice 2026-11 – Interim Guidance on Additional First Year Depreciation Deduction For eligible assets placed in service in 2026, the entire cost can come off in year one.
Combine the two, and a company that buys $2 million of equipment in 2026 could expense all of it on that year’s tax return. On the balance sheet, gross fixed assets still shows $2 million, but tax-basis accumulated depreciation jumps to $2 million as well. Tax-basis net fixed assets: zero. Book-basis NFA, meanwhile, still reflects whatever useful life management picked for financial reporting.
When Impairment Forces an Early Write-Down
Depreciation follows a schedule. Real-world value loss doesn’t always wait. When circumstances suggest a fixed asset’s carrying amount may no longer be recoverable, the company has to test the asset for impairment and, if the test fails, write it down in a single charge that bypasses the normal depreciation timeline.
Fixed assets don’t require annual impairment testing the way goodwill does. The test happens only when a triggering event occurs: a significant drop in the asset’s market price, a major adverse change in how the asset is being used or in its physical condition, unfavorable legal or regulatory developments, cost overruns well above original estimates, or ongoing operating losses tied to the asset. A production line that gets shut down, for instance, forces the company to look at whether the idle equipment’s carrying value still reflects recoverable value.
If the testing shows that future cash flows won’t cover the asset’s book value, the company records an impairment loss and permanently reduces net fixed assets. Impairment charges aren’t predictable the way depreciation is, and a single one can materially change the NFA balance in one reporting period. When a company’s PP&E drops suddenly without any disposals or any change in depreciation, an impairment charge is usually the reason.
What Happens When an Asset Is Sold or Retired
Fixed assets eventually leave the balance sheet. When a company sells, scraps, or otherwise disposes of one, both the original gross cost and all the related accumulated depreciation come off the books. The difference between what the company receives and the asset’s remaining carrying value determines whether the disposal produces a gain or a loss.
The arithmetic: original cost minus accumulated depreciation gives carrying value; compare carrying value to proceeds. A machine purchased for $500,000 with $400,000 in accumulated depreciation has a carrying value of $100,000. Sell it for $130,000, the company records a $30,000 gain. Sell it for $60,000, it takes a $40,000 loss.
Fully depreciated assets that remain in service are common. The asset sits on the balance sheet at its original cost alongside an equal amount of accumulated depreciation, carrying value zero. No further depreciation runs through the income statement, and no journal entry is required until the company actually disposes of the asset. These “ghost assets” accumulate in the fixed asset register over time, which is why periodic physical verification of the asset base matters for accurate reporting.
How the Number Appears on the Balance Sheet
Net fixed assets lives in the non-current assets section of the balance sheet, below current assets like cash and receivables. The face of the statement usually shows one line, “Property, Plant, and Equipment, Net,” that blends every building, machine, vehicle, and piece of furniture the company owns, reduced by all accumulated depreciation across those assets.
The notes to the financial statements break that single number apart. GAAP requires disclosure of the balances of major classes of depreciable assets (buildings, machinery, furniture, and so on), accumulated depreciation by class or in total, depreciation expense for the period, and a description of the methods used for each major asset class. The notes are where you see whether the company leans heavily on one asset category or carries a diverse base of equipment and property.
Construction in Progress
Assets still under construction appear within PP&E in an account called construction in progress (CIP). Costs accumulate while a building goes up or a production line gets installed, but depreciation doesn’t start until the asset is substantially complete and ready for its intended use. A company building a new factory might carry $40 million of CIP that inflates total PP&E without producing any depreciation expense, temporarily making the net fixed asset figure look higher than it will once the project finishes and depreciation starts.
Leased Assets
Under current lease accounting rules (ASC 842), lessees record right-of-use (ROU) assets on the balance sheet for both operating and finance leases. ROU assets represent the right to use the property during the lease term, not ownership of the underlying asset. The standards call for ROU assets to be presented separately from owned fixed assets, though finance-lease ROU assets sometimes get folded into the PP&E line on the face of the balance sheet. Before running any analysis on a company’s NFA, check whether ROU assets are inside the PP&E total or broken out separately. Mixing them in distorts every ratio you’d calculate.
Using Net Fixed Assets in Financial Analysis
NFA feeds several ratios that measure how efficiently a company deploys its capital base. The ratios are most useful when compared against peers in the same industry, because capital requirements vary dramatically by business model.
Fixed Asset Turnover
This ratio measures how much revenue the company gets from each dollar of fixed assets. Net revenue divided by average net fixed assets for the period. A company generating $10 million in sales from $2 million in average net fixed assets has a turnover ratio of 5.0, meaning each dollar of fixed assets produces $5 in revenue.
A high ratio generally points to efficient capital use or high capacity utilization. A low ratio can mean overinvestment in physical assets, underutilized capacity, or simply that the company recently completed a large capital expansion and hasn’t yet grown revenue to match. A brand-new plant will drag the ratio down for years before reaching full production, and that isn’t necessarily a problem.
Average Asset Age
Accumulated depreciation divided by gross fixed assets gives the percentage of the asset base’s useful life already consumed. If a company shows $600,000 of accumulated depreciation against $1,000,000 of gross fixed assets, roughly 60% of the depreciable life is gone. A high percentage flags an aging infrastructure that will probably need expensive replacement soon, pressuring future cash flow. A low percentage suggests recent investment.
The metric is rough. Different depreciation methods, varying useful lives across asset classes, and the mix of old versus new assets all introduce noise. But it’s a quick read on whether the company has been investing in its operational base or coasting on aging equipment.
Capital Intensity
Net fixed assets divided by total assets shows how much of the company’s resources are tied up in physical infrastructure. Manufacturing, utility, and transportation companies often run capital intensity ratios above 50%, reflecting dependence on factories, pipelines, and fleets. Technology and professional services firms often sit below 15%, since their value comes from people and intellectual property rather than physical equipment. A ratio that looks alarming for one industry is normal for another, so always compare within a peer group.
