What is Property, Plant and Equipment (PPE)?

Property, plant and equipment (PPE) is one of the most important categories on a company's balance sheet: the tangible, long-term assets a business uses to operate, such as land, buildings, machinery and vehicles. How PPE is recognised, measured and depreciated is governed by the accounting standard IAS 16, and it's a core topic in financial reporting. This guide explains what PPE is, how it's accounted for, the key concept of depreciation, and why it matters — in plain language. It's fundamental to qualifications like ACCA and CIMA.

What is property, plant and equipment?

Property, plant and equipment are tangible assets that a business holds for use in producing or supplying goods and services, for renting to others, or for administrative purposes, and which are expected to be used for more than one accounting period. The two defining features are that they are physical (tangible) and long-term (non-current). Typical examples include land and buildings, plant and machinery, fixtures and fittings, office equipment and motor vehicles. PPE is distinct from inventory (held for sale) and from intangible assets (which have no physical form).

How PPE is initially recognised and measured

Under IAS 16, an item of PPE is recognised as an asset only when it is probable that it will bring future economic benefits to the business and its cost can be measured reliably. When first recognised, PPE is measured at its cost — and importantly, cost includes more than just the purchase price. It comprises the purchase price (including import duties and non-refundable taxes), the directly attributable costs of getting the asset to its location and into working condition (such as delivery, installation and testing), and an estimate of any costs of dismantling and removing it at the end of its life. Day-to-day running costs, by contrast, are expensed, not capitalised.

Depreciation: spreading the cost

Because PPE is used over many years, its cost is spread across its useful life through depreciation — the systematic allocation of an asset's cost (less any expected residual value) over the periods that benefit from its use. Depreciation matches the cost of using the asset to the revenue it helps generate, in line with the accruals concept. Common methods include the straight-line method (an equal charge each year) and the reducing-balance method (a higher charge in earlier years). Notably, land is generally not depreciated, as it's considered to have an unlimited useful life. Depreciation is an accounting allocation, not a cash outflow, and it reduces the asset's carrying value on the balance sheet over time.

The cost and revaluation models

After initial recognition, IAS 16 allows a business to choose between two models for measuring PPE:

• The cost model. The asset is carried at its cost less accumulated depreciation and any impairment losses.
• The revaluation model. The asset is carried at its fair value at the revaluation date, less subsequent depreciation. This keeps the asset's value current but requires revaluations to be kept up to date, with gains usually recorded in a revaluation surplus.

The choice is applied consistently to whole classes of assets, not cherry-picked item by item.

Why PPE matters

PPE often represents a substantial portion of a company's assets, particularly in capital-intensive industries like manufacturing, utilities and transport. How it's accounted for directly affects the balance sheet (asset values) and the income statement (through depreciation), and therefore key measures of profitability and financial position. Getting PPE accounting right — what to capitalise, how to depreciate, when to revalue or impair — is essential for a true and fair view of a business, which is why IAS 16 is such a foundational standard.

Why it matters for finance professionals

For anyone in accounting, audit or financial reporting, PPE and IAS 16 are essential knowledge. The principles — recognition, measurement at cost, depreciation, and the choice between cost and revaluation models — recur constantly in practice and in exams. A solid grasp of how long-term tangible assets are accounted for is fundamental to preparing and interpreting financial statements, and a heavily examined topic in professional qualifications.

Frequently asked questions

What is property, plant and equipment (PPE)?

Tangible, long-term assets a business uses in its operations — such as land, buildings, machinery and vehicles — expected to be used for more than one accounting period. PPE accounting is governed by IAS 16.

How is PPE initially measured?

At cost, which includes the purchase price plus directly attributable costs of getting the asset ready for use (delivery, installation, testing) and any estimated dismantling and removal costs.

What is depreciation?

The systematic allocation of an asset's cost, less its residual value, over its useful life — matching the cost of using the asset to the revenue it generates. Land is generally not depreciated.

What's the difference between the cost and revaluation models?

The cost model carries PPE at cost less accumulated depreciation and impairment; the revaluation model carries it at fair value less subsequent depreciation, keeping the value current but requiring regular revaluation.
