IAS 23 is the International Accounting Standard on Borrowing Costs. In plain terms, it tells a company when interest and similar financing costs should be added to the cost of a long-term asset and when they should be recognized as an expense immediately. This matters because IAS 23 can change reported profit, asset values, project economics, and how investors interpret a company’s financial statements.

1. Term Overview

• Official Term: IAS 23
• Common Synonyms: International Accounting Standard 23, IAS 23 Borrowing Costs, Borrowing Costs standard
• Alternate Spellings / Variants: IAS-23
• Domain / Subdomain: Finance / Accounting Standards and Frameworks
• One-line definition: IAS 23 is the accounting standard that governs how borrowing costs are treated, especially whether they must be capitalized as part of the cost of a qualifying asset.
• Plain-English definition: If a business borrows money to build, make, or develop an asset that takes a long time to get ready, IAS 23 may require part of the interest cost to be added to that asset instead of being charged to profit right away.
• Why this term matters:
• It affects profit or loss in the current period.
• It affects asset carrying values on the balance sheet.
• It changes future depreciation or amortization.
• It matters in construction, infrastructure, manufacturing, real estate, energy, and long-cycle development projects.
• It is important for auditors, analysts, lenders, students, and IFRS preparers.

2. Core Meaning

What it is

IAS 23 is the IFRS/IAS standard that deals with borrowing costs. Its main rule is simple:

• Borrowing costs directly attributable to a qualifying asset must be capitalized.
• Other borrowing costs are recognized as an expense when incurred.

Why it exists

When a company spends years building a factory, power plant, or real estate project, the financing cost is part of getting that asset ready. IAS 23 exists to avoid treating all such interest as a period expense when part of it is closely linked to creating the asset itself.

What problem it solves

Without a standard like IAS 23:

• One company might expense all interest immediately.
• Another might capitalize large amounts.
• Similar projects would become hard to compare.
• Profit could swing based on inconsistent accounting choices.

IAS 23 creates a more disciplined and comparable approach.

Who uses it

IAS 23 is used by:

• Companies preparing IFRS financial statements
• Accountants and finance teams
• Auditors
• Financial analysts
• Investors reviewing capital-intensive businesses
• Regulators and enforcement bodies
• Students and exam candidates studying IFRS

Where it appears in practice

You usually see IAS 23 in:

• Property, plant and equipment under construction
• Real estate development
• Large infrastructure projects
• Certain inventories taking a substantial time to produce
• Some self-developed intangible assets
• Accounting policy disclosures
• Notes explaining capitalized borrowing costs and capitalization rates

3. Detailed Definition

Formal definition

IAS 23 is the International Accounting Standard titled Borrowing Costs, which prescribes the accounting treatment for borrowing costs.

Technical definition

Under IAS 23, an entity capitalizes borrowing costs that are directly attributable to the acquisition, construction, or production of a qualifying asset as part of the cost of that asset. Other borrowing costs are recognized as an expense in the period in which they are incurred.

Operational definition

In day-to-day accounting, IAS 23 asks five practical questions:

1. Is the asset a qualifying asset?
2. Are borrowing costs being incurred?
3. Are expenditures being incurred on the asset?
4. Are activities necessary to prepare the asset for use or sale in progress?
5. If yes, how much of the borrowing cost should be capitalized?

Context-specific definitions

Under IFRS / IAS reporting

IAS 23 refers specifically to the standard on borrowing costs within the IFRS and IAS framework.

In India

The comparable standard is typically Ind AS 23, which is substantially aligned with IAS 23, subject to local adoption and regulatory context.

In the UK and EU

Entities using UK-adopted or EU-endorsed international standards generally apply the equivalent endorsed version of IAS 23.

In the United States

“IAS 23” is not the governing standard under U.S. GAAP. The broadly comparable area is covered by ASC 835-20, but the mechanics and terminology are not identical.

Important scope note

IAS 23 generally applies to qualifying assets, but there are important exceptions and judgments, including assets measured at fair value and certain inventories produced in large quantities on a repetitive basis. Readers should verify the latest applicable text in their reporting framework.

4. Etymology / Origin / Historical Background

Origin of the term

• IAS stands for International Accounting Standard.
• 23 is the standard number assigned to the borrowing costs standard.

So “IAS 23” simply means the 23rd standard in the IAS series.

Historical development

IAS 23 has existed for decades as part of the international accounting framework. The standard evolved as global reporting moved toward stronger consistency and comparability in financial statements.

How usage changed over time

Historically, accounting frameworks often debated whether borrowing costs should be:

• expensed immediately, or
• included in asset cost.

A major development in IAS 23 was the removal of the old choice that allowed directly attributable borrowing costs to be expensed immediately. The revised approach strengthened the rule that such costs should generally be capitalized for qualifying assets.

Important milestones

Broadly, the important milestones are:

• early issuance of a dedicated borrowing-cost standard in the IAS framework
• later revision that made capitalization of directly attributable borrowing costs mandatory
• updates to align terminology with newer standards such as IFRS 9 and IFRS 16

For exact issue dates, amendments, and local endorsement timing, users should check the latest official version applicable in their jurisdiction.

5. Conceptual Breakdown

1. Borrowing costs

Meaning: These are financing costs arising from borrowing funds.
Role: They are the raw cost item IAS 23 evaluates.
Interaction: Only some borrowing costs qualify for capitalization.
Practical importance: Misclassifying borrowing costs can overstate assets or overstate expenses.

Borrowing costs may include:

• interest expense using the effective interest method
• certain finance charges on lease liabilities
• some foreign exchange differences, but only to the extent treated as an adjustment to interest cost

2. Qualifying asset

Meaning: An asset that necessarily takes a substantial period of time to get ready for its intended use or sale.
Role: This is the gateway test. No qualifying asset, no IAS 23 capitalization.
Interaction: The nature of the asset determines whether borrowing costs go to the balance sheet or profit and loss.
Practical importance: This is one of the most judgment-heavy areas.

Examples can include:

• factories under construction
• power plants
• large real estate developments
• certain inventories with long production cycles
• some self-developed intangible assets

Usually not qualifying:

• assets ready for use when purchased
• financial assets
• routine short-cycle inventory

3. Direct attribution

Meaning: The borrowing cost must be directly connected to acquiring, constructing, or producing the qualifying asset.
Role: Prevents a business from capitalizing unrelated financing costs.
Interaction: Direct attribution is clearer for specific project loans, but more judgmental for general borrowings.
Practical importance: This is often reviewed closely by auditors.

4. Capitalization

Meaning: Adding eligible borrowing costs to the carrying amount of the asset rather than expensing them immediately.
Role: Moves cost from current profit and loss into the asset base.
Interaction: Increases future depreciation or amortization.
Practical importance: It can improve current profit but increase future expense.

5. Specific borrowings

Meaning: Borrowings taken specifically for a qualifying asset.
Role: Usually the first source considered for capitalization.
Interaction: Actual borrowing costs on those funds are generally used, adjusted for temporary investment income where relevant.
Practical importance: Easier to trace, but still requires careful documentation.

6. General borrowings

Meaning: Borrowings not taken specifically for one qualifying asset but used in the business overall.
Role: If qualifying-asset expenditures exceed specific borrowings, general borrowings may support additional capitalization.
Interaction: A capitalization rate is applied to relevant expenditures.
Practical importance: The calculation can become complex in groups with multiple debt instruments.

7. Commencement of capitalization

Meaning: Capitalization begins only when all required conditions are met.
Role: Prevents premature capitalization.
Interaction: All three generally need to be present: – expenditures on the asset – borrowing costs incurred – activities to prepare the asset underway
Practical importance: Start dates can materially affect reported profit.

8. Suspension of capitalization

Meaning: Capitalization is suspended during extended periods when active development is interrupted.
Role: Stops entities from capitalizing interest during idle periods that are not part of the normal build process.
Interaction: Normal technical or administrative work may still support capitalization; unnecessary long pauses usually do not.
Practical importance: Delayed projects create audit risk.

9. Cessation of capitalization

Meaning: Capitalization stops when substantially all activities necessary to prepare the asset are complete.
Role: Prevents capitalization after the asset is essentially ready.
Interaction: If separable parts of a project are completed at different times, capitalization may stop part by part.
Practical importance: Over-capitalization often happens here.

10. Disclosure

Meaning: Financial statements must explain the amount capitalized and the capitalization rate used for general borrowings.
Role: Supports transparency.
Interaction: Helps investors and auditors assess reasonableness.
Practical importance: Weak disclosure is a red flag.

6. Related Terms and Distinctions

Related Term	Relationship to Main Term	Key Difference	Common Confusion
Borrowing Costs	Core subject of IAS 23	Borrowing costs are the cost item; IAS 23 is the rulebook	People often use the term and the standard interchangeably
Qualifying Asset	Central trigger for capitalization	Not every asset qualifies	Many assume all long-lived assets automatically qualify
Capitalization	Main accounting treatment under IAS 23	Capitalization means adding cost to an asset, not raising capital from investors	“Capitalization” is often confused with market capitalization or share capital
Capitalization Rate	Measurement tool for general borrowings	It is a weighted financing rate, not a real estate cap rate	The term “cap rate” has different meanings in different finance contexts
Specific Borrowings	One source of eligible borrowing costs	These are traced directly to the project	Some wrongly mix them with all company debt
General Borrowings	Indirect source of financing for the asset	Uses a weighted rate, not exact tracing	Often confused with treasury funding or working capital borrowing only
IAS 16	Works with IAS 23 for PPE	IAS 16 governs asset cost and depreciation; IAS 23 governs borrowing cost treatment	Readers sometimes think IAS 16 alone covers construction finance
IAS 2	Relevant for inventories	IAS 2 covers inventory measurement; IAS 23 may affect inventory cost if it qualifies	Many assume inventory never qualifies
IAS 38	Relevant for intangibles	IAS 38 governs recognition of intangible assets; IAS 23 may add borrowing costs if development creates a qualifying asset	Not all software or R&D costs qualify
IFRS 9	Defines effective interest mechanics	IAS 23 may use interest amounts determined under IFRS 9 principles	People may use contractual rate instead of effective interest when inappropriate
IAS 36	Relevant after capitalization	Even if borrowing costs are capitalized, the asset may later be impaired	Capitalization does not guarantee recoverability
ASC 835-20	U.S. GAAP comparison point	Similar area under U.S. GAAP, but not the same standard	“IAS 23” and “U.S. interest capitalization” are often treated as identical
Ind AS 23	Indian equivalent framework term	Substantially converged local version	Users may assume wording and regulatory environment are always identical

7. Where It Is Used

Analytics and research

Researchers and analysts use IAS 23 data to compare:

• capital intensity
• financing structure
• quality of earnings
• project execution discipline

8. Use Cases

Use Case 1: Building a manufacturing plant

• Who is using it: Industrial company finance team
• Objective: Measure the true cost of a new plant under IFRS
• How the term is applied: Interest on project financing during construction is evaluated under IAS 23 and capitalized if directly attributable
• Expected outcome: Plant cost includes eligible financing costs incurred before readiness
• Risks / limitations: Starting too early or continuing too long can overstate PPE

Use Case 2: Real estate development

• Who is using it: Property developer
• Objective: Account correctly for borrowing costs during project development
• How the term is applied: Borrowing costs on land development and construction may be capitalized while the project is actively being prepared for sale
• Expected outcome: Project inventory or development asset reflects eligible financing cost
• Risks / limitations: Need careful judgment on whether activities are active, suspended, or substantially complete

Use Case 3: Infrastructure or renewable energy project

• Who is using it: Utility or infrastructure sponsor
• Objective: Match financing cost with a long construction period
• How the term is applied: Specific project debt and, where relevant, general borrowings are assessed under IAS 23
• Expected outcome: More faithful measurement of project cost during construction
• Risks / limitations: Complex debt structures, phased completion, and delays can complicate calculations

Use Case 4: Long-cycle inventory production

• Who is using it: Beverage, shipbuilding, or specialty manufacturing business
• Objective: Determine whether borrowing costs should be part of inventory cost
• How the term is applied: If inventory takes a substantial period to get ready, IAS 23 may become relevant, subject to scope exceptions and policy choices allowed by the standard
• Expected outcome: Better cost matching where appropriate
• Risks / limitations: Some repetitive, large-volume inventories may fall within an exemption from mandatory application

Use Case 5: Self-developed intangible asset

• Who is using it: Technology or pharma company
• Objective: Determine whether development-phase borrowing costs should be capitalized
• How the term is applied: If an intangible asset is being developed and qualifies under the relevant recognition rules, IAS 23 may permit or require capitalization of directly attributable borrowing costs
• Expected outcome: Eligible financing cost becomes part of the intangible asset
• Risks / limitations: Research activities usually do not qualify; recognition under the intangible-asset standard remains critical

Use Case 6: Audit review of project financing

• Who is using it: External auditors or internal audit
• Objective: Test compliance with IFRS
• How the term is applied: Auditors check qualifying-asset status, start/stop dates, rates, calculations, and disclosures
• Expected outcome: Reliable financial statements and reduced risk of misstatement
• Risks / limitations: Poor project documentation can make verification difficult

9. Real-World Scenarios

A. Beginner scenario

• Background: A small manufacturer borrows to buy a machine that is ready for use as soon as delivered.
• Problem: The owner thinks all loan interest should be added to the machine cost.
• Application of the term: IAS 23 asks whether the machine is a qualifying asset. Since it is ready for use when purchased, usually it is not.
• Decision taken: Interest is expensed, not capitalized.
• Result: The machine is recorded at purchase-related cost, but financing cost goes to profit and loss.
• Lesson learned: Not every asset financed by debt qualifies under IAS 23.

B. Business scenario

• Background: A listed company is building a new cement plant over two years.
• Problem: Management must decide how much interest should be included in construction work-in-progress.
• Application of the term: Specific construction debt is traced to the project, and a capitalization rate is used for any relevant general borrowings.
• Decision taken: The company capitalizes directly attributable borrowing costs from the date capitalization criteria are met until the plant is substantially ready.
• Result: Current finance expense is lower than it would have been if all interest were expensed immediately.
• Lesson learned: IAS 23 affects both the balance sheet and the timing of expenses.

C. Investor / market scenario

• Background: An equity analyst compares two infrastructure companies.
• Problem: One company reports higher profit even though both are building major projects.
• Application of the term: The analyst checks whether one company capitalized more borrowing costs under IAS 23.
• Decision taken: The analyst adjusts the comparison by reviewing capitalized borrowing costs, project stage, and future depreciation impact.
• Result: The analyst realizes part of the profit difference is accounting timing, not necessarily better economics.
• Lesson learned: IAS 23 can affect earnings quality analysis.

D. Policy / government / regulatory scenario

• Background: A securities regulator reviews the annual report of a large real estate developer.
• Problem: The company kept capitalizing borrowing costs during a long project delay caused by internal funding problems.
• Application of the term: IAS 23 generally requires suspension during extended interruptions where active development is not progressing.
• Decision taken: The regulator questions the accounting treatment and disclosure.
• Result: The company may need to restate or improve its note disclosures and controls.
• Lesson learned: Capitalization during idle periods is a major regulatory risk area.

E. Advanced professional scenario

• Background: A multinational group finances a data center with both project-specific debt and central treasury borrowings.
• Problem: The group must calculate capitalized borrowing costs across multiple currencies, debt layers, and project phases.
• Application of the term: Finance teams identify qualifying expenditures, use actual project-loan costs first, apply an appropriate capitalization rate to excess expenditures, and assess whether any foreign exchange element qualifies only as an interest adjustment.
• Decision taken: The group documents the rate methodology, project timeline, and suspension analysis.
• Result: The financial statements are supportable on audit and comparable across reporting periods.
• Lesson learned: IAS 23 is conceptually simple but technically demanding in real treasury environments.

10. Worked Examples

Simple conceptual example

A retailer buys ready-to-use display shelves using a bank loan.

• The shelves are available for immediate use.
• They do not take a substantial period to get ready.
• Therefore, they are not usually a qualifying asset.

Result: Loan interest is normally expensed, not capitalized.

Now compare that with a retailer building a new warehouse over 18 months.

• The warehouse takes a substantial period to get ready.
• Borrowing costs directly attributable to construction may be capitalized.

Result: Same debt concept, different accounting outcome because the asset type and preparation period differ.

Practical business example

A company is constructing a new bottling plant. It took a specific term loan for construction and also uses existing working-capital facilities for some payments.

How IAS 23 applies:

1. Determine whether the bottling plant is a qualifying asset.
2. Identify when expenditures, borrowing costs, and construction activities all begin.
3. Capitalize actual eligible cost on the specific project loan.
4. Apply a capitalization rate to qualifying expenditures funded by general borrowings.
5. Stop capitalization when the plant is substantially ready for use.

Accounting effect:
– Construction work-in-progress increases
– Current finance cost expense decreases
– Future depreciation increases once the plant is operational

Numerical example

A company is building a warehouse and has only general borrowings.

Borrowings:

• Loan A: 5,000,000 at 8%
• Loan B: 3,000,000 at 6%

Step 1: Compute total annual borrowing costs

• Loan A cost = 5,000,000 × 8% = 400,000
• Loan B cost = 3,000,000 × 6% = 180,000
• Total = 580,000

Step 2: Compute capitalization rate

Capitalization rate:

[ \text{Capitalization Rate} = \frac{580,000}{8,000,000} = 7.25\% ]

Step 3: Determine expenditures on the qualifying asset

• 2,000,000 spent on January 1
• 1,500,000 spent on July 1

Step 4: Compute weighted average accumulated expenditures

• January expenditure weighted for 12/12 months:
  2,000,000 × 12/12 = 2,000,000
• July expenditure weighted for 6/12 months:
  1,500,000 × 6/12 = 750,000

Total weighted average accumulated expenditures:

[ 2,000,000 + 750,000 = 2,750,000 ]

Step 5: Compute borrowing costs eligible for capitalization

[ 2,750,000 \times 7.25\% = 199,375 ]

Answer:
The company capitalizes 199,375 of borrowing costs, subject to the general ceiling that capitalized borrowing costs cannot exceed actual borrowing costs incurred.

Advanced example

A company is constructing a data center using both specific and general borrowings.

Specific borrowing:

• Project loan: 4,000,000 at 10%
• Temporary investment income on unused specific funds: 20,000

General borrowings:

• Weighted capitalization rate: 7%

Project expenditures:

• January 1: 2,500,000
• May 1: 2,000,000
• November 1: 1,500,000

Step 1: Capitalization from specific borrowing

Annual interest on specific loan:

[ 4,000,000 \times 10\% = 400,000 ]

Less temporary investment income:

[ 400,000 – 20,000 = 380,000 ]

So, eligible borrowing cost from the specific borrowing is 380,000.

Step 2: Determine expenditures exceeding the specific borrowing

Specific borrowing covers up to 4,000,000.

• After January 1 spend of 2,500,000: no excess
• After May 1 cumulative spend = 4,500,000: excess = 500,000
• After November 1 cumulative spend = 6,000,000: excess = 2,000,000

Step 3: Compute weighted excess expenditures funded by general borrowings

• Excess of 500,000 from May 1 to year-end: 8/12
  [ 500,000 \times \frac{8}{12} = 333,333 ]

• Additional excess of 1,500,000 from November 1 to year-end: 2/12
  [ 1,500,000 \times \frac{2}{12} = 250,000 ]

Total weighted excess expenditures:

[ 333,333 +
