What it means
The accounting test for an asset is not whether you paid for it, but whether you control it and expect future benefit from it. That is why a leased machine you effectively control usually sits on the balance sheet, while a brilliant sales team, which you do not own, does not.
Assets divide into tangible items you can physically touch, such as delivery vans and laptops, and intangible items such as purchased software licences, patents and acquired customer lists. Intangibles cause the most confusion because internally generated ones, like the value of your own brand, are generally not recorded even when everyone agrees they are valuable.
Most non-current assets are recorded at what you paid and then written down over their useful life through depreciation, or amortisation in the case of intangibles. This is not an attempt to track market value; it is a way of spreading the cost across the years the asset actually helps generate revenue.
The business reason to care is that assets drive both borrowing capacity and tax. Lenders look at what could be sold or pledged as security, tax rules often allow capital allowances on qualifying asset purchases, and investors judge how efficiently you turn assets into sales.
The nuance that trips people up is the difference between an asset and an expense. Buying a $900 office chair is usually treated as an expense because of its low value, while buying a $40,000 machine is capitalised as an asset, and most companies set a written threshold so the decision is consistent.
In practice
Real-world examples.
Example
A bakery buys a $48,000 industrial oven and records it as a non-current asset rather than an expense. Its accountant depreciates it over eight years, so the profit and loss account carries $6,000 a year instead of one large hit in the year of purchase.
Example
A logistics firm applying for a $500,000 loan is asked for an asset register. The lender values the fleet and the freehold depot as security and offers a lower interest rate than it would for an unsecured facility.
Example
A design agency writes off three old iMacs that no longer work. Because they were already fully depreciated, removing them from the asset register changes the balance sheet very little but keeps insurance and audit records accurate.
Formula
Calculation
Two formulas matter here. Straight-line annual depreciation = (cost - residual value) / useful life, and net book value = cost - accumulated depreciation.
A courier business buys a delivery van for $60,000. It expects to use the van for five years and to sell it afterwards for around $10,000, which is the residual value. Annual depreciation is ($60,000 - $10,000) / 5 = $50,000 / 5 = $10,000 per year.
After three years, accumulated depreciation is 3 x $10,000 = $30,000. The van's net book value is $60,000 - $30,000 = $30,000, which is the figure that appears in the non-current assets section of the balance sheet.
If the company then sold the van for $34,000, it would record a gain of $34,000 - $30,000 = $4,000, because the sale proceeds exceeded the carrying amount rather than the original cost.Case study
Seen in the real world.
This case study is illustrative and the company is fictional. Thornbury Cold Chain is an invented refrigerated haulage business that grew quickly and kept no formal asset register, tracking purchases only through bank statements.
When it applied for finance to buy two more trailers, the lender asked for a schedule of assets with purchase dates, costs and accumulated depreciation. The finance manager spent three weeks reconstructing the list and discovered $85,000 of equipment recorded as expenses in prior years, along with two trailers still on the books that had been sold.
After correcting the register, Thornbury's balance sheet showed a healthier asset base, its insurance cover matched what it actually owned, and the lender approved the facility. The illustrative point is that assets do not manage themselves; the register is what turns ownership into borrowing power.
Watch out
Common mistakes.
- Treating every purchase as an expense, which understates the balance sheet and makes the business look weaker to lenders.
- Assuming net book value is what an asset would sell for, when book value is simply cost less depreciation charged so far.
- Forgetting to remove sold, scrapped or stolen assets from the register, which distorts both accounts and insurance cover.
Questions
People also ask.
Is stock a business asset?
Yes, inventory is a current asset because it is expected to be sold and converted into cash within the normal trading cycle.
Are people assets?
Not in accounting terms, because a business does not own or control its employees, however valuable they are.
What is a capitalisation threshold?
It is the value a company sets, often between $500 and $2,500, above which a purchase is recorded as an asset rather than an expense.
