Construction Work In Progress (CWIP) refers to construction projects that are still in progress and not yet complete. It is the account that holds the cost of a building, a production line or any other long-term asset while it is being built. Understanding CWIP matters to any business with capital projects, because it affects the balance sheet, the timing of depreciation, tax and how projects are managed.
This guide explains what CWIP is, what costs go into it, how CWIP accounting works under US GAAP with journal entries and a worked example, how it differs from the “work in progress” a contractor reports on customer contracts, and how to keep it from turning into a pile of costs nobody can explain.
What Is CWIP?
CWIP, short for construction work in progress, is a balance sheet account that collects the costs of a long-term asset being built or installed until it is ready for use. It sits within property, plant and equipment, it is not depreciated, and when the asset is placed in service its balance moves to the right fixed asset accounts.
You will see the same account under other names:
- Construction in progress (CIP), the most common label in US financial statements.
- Capital work in progress, common in India and other countries that report under IFRS-based standards.
- Assets under construction, often used in ERP systems and fixed asset modules.
Typical CWIP projects include a new warehouse, a building extension, a production line, a large machine that takes months to install, and a major refurbishment that extends an asset’s life.
Understanding the Purpose of CWIP
CWIP keeps the cost of unfinished assets separate from assets already in use. That separation matters for three reasons:
- Depreciation starts at the right time. An asset is depreciated from when it is placed in service, ready for its intended use. Holding costs in CWIP stops anyone depreciating a half-built warehouse.
- The balance sheet is honest. Investors and lenders can see how much capital is tied up in projects that are not yet earning anything.
- Project costs are controlled. A CWIP account per project shows what has been spent against the budget, while there is still time to act.
What are the Key Components of CWIP?
Under US GAAP, the cost of a self-constructed asset includes every cost needed to bring it to the condition and location for its intended use. These are the costs that typically go into CWIP:
| Cost | Goes into CWIP? | Notes |
|---|---|---|
| Materials | Yes | Including materials bought for the project and delivered to site |
| Direct labor | Yes | Wages and benefits of people working on the asset |
| Contractor and subcontractor billings | Yes | Progress billings for work performed |
| Design, engineering and architect fees | Yes | Fees tied to this project |
| Permits, inspections and site preparation | Yes | Including demolition needed to prepare the site |
| Depreciation of equipment used in construction | Yes | The share of the company’s own equipment used on the project |
| Interest during construction | Yes, for qualifying assets | Capitalized interest under US GAAP; IFRS also requires capitalizing borrowing costs |
| Testing before the asset is ready | Yes | Costs of checking the asset works as intended |
| Directly attributable overhead | Yes | Only overhead that the project actually caused |
| General administration and unrelated overhead | No | Expensed as incurred |
| Training staff to use the asset | No | Expensed as incurred |
| Costs of abnormal waste, rework or delays | No | Expensed as incurred |
| Signed commitments not yet performed | No | Disclosed as commitments, not recorded as CWIP |
The line between “directly attributable” and “general” overhead is where most disagreements with auditors start. Write your policy down and apply it the same way to every project.
CWIP Accounting: How It Works
CWIP accounting follows the project through four stages. Each stage has its own journal entry.
- Record costs as they are incurred. Each invoice, payroll allocation or capitalized interest charge for the project is debited to CWIP, not to an expense or a fixed asset account.
- Review the balance each period. Check that every cost belongs to the project and to CWIP, and that nothing that should be expensed has slipped in.
- Place the asset in service. When the asset is ready for its intended use, transfer the CWIP balance to the right fixed asset accounts, split by component if they have different useful lives.
- Start depreciation. Depreciation begins from the in-service date, using each asset’s useful life and method.
The journal entries look like this:
| When | Debit | Credit |
|---|---|---|
| A cost is incurred | Construction work in progress | Cash or accounts payable |
| Interest is capitalized | Construction work in progress | Interest expense |
| The asset is placed in service | Buildings, machinery or other asset accounts | Construction work in progress |
| Each period after that | Depreciation expense | Accumulated depreciation |
Is CWIP Depreciated?
No. CWIP is not depreciated, because the asset is not yet in use. Depreciation begins when the asset is placed in service, under US GAAP and for US tax depreciation alike. Under IFRS the trigger is when the asset is available for use, which works out the same way in practice.
CWIP can still lose value. If a project is abandoned, or there are signs its cost will not be recovered, the balance is tested for impairment and written down. A project that has been “almost finished” for two years is a common warning sign.
Worked Example: A New Warehouse
A distributor builds a warehouse over 10 months and records these costs in CWIP:
| Cost | Amount |
|---|---|
| Site preparation | $120,000 |
| Contractor progress billings | $1,800,000 |
| Architect and engineering fees | $95,000 |
| Permits and inspections | $15,000 |
| Capitalized interest on the construction loan | $40,000 |
| CWIP balance at completion | $2,070,000 |
During construction, the balance sheet shows $2,070,000 of construction in progress within property, plant and equipment, and the income statement shows no depreciation for it. When the warehouse is placed in service, the company moves the balance to the components it will depreciate separately:
| Asset account | Amount | Useful life |
|---|---|---|
| Building | $1,656,000 | 40 years |
| Racking | $250,000 | 10 years |
| Dock equipment | $164,000 | 15 years |
| Total transferred from CWIP | $2,070,000 |
The useful lives here are the company’s own book estimates. Tax depreciation follows its own recovery periods, which our MACRS depreciation calculator works out by asset class. From the in-service date, each component is depreciated, and accumulated depreciation starts to build. If that term is new, see is accumulated depreciation an asset or a liability?
What are the different Accounting Methods for CWIP?
The phrase “work in progress” is used for two different things in construction, and mixing them up causes most of the confusion around CWIP.
| CWIP for your own assets | Contract work in progress | |
|---|---|---|
| Who has it | Any company building an asset it will use | A contractor building for a customer |
| What it is | A capitalized cost, part of property, plant and equipment | Revenue and cost on customer contracts |
| Depreciated? | No, until placed in service | Never; it is not a fixed asset |
| US GAAP guidance | Property, plant and equipment rules | Revenue from contracts with customers (ASC 606) |
| On the balance sheet | Construction in progress | Contract assets and contract liabilities |
Methods for CWIP on Your Own Assets
There is one method: capitalize the costs as incurred, hold them in CWIP, and transfer them to fixed assets when the asset is placed in service. The choices you make are about policy, such as what overhead to include and how to split the cost into components.
Methods for Contractors’ Work in Progress
A contractor building for a customer recognizes revenue under ASC 606. Most construction contracts transfer control to the customer as the work is done, so revenue is recognized over time by measuring progress toward completion. The usual measure is an input method such as costs incurred to date as a share of total expected costs, the approach long known as the percentage-of-completion method.
- When progress cannot be reasonably measured, but the contractor expects to recover its costs, revenue is recognized only to the extent of costs incurred until progress can be measured. Older guidance called this the zero-profit approach.
- When a contract is expected to lose money, the whole expected loss is recognized as soon as it is known.
- The completed contract method, which recognizes all revenue at the end, is no longer used for US GAAP financial statements of contracts that transfer control over time. It survives for US tax purposes for certain small contractors and home construction contracts.
Contractors track this on a work-in-progress schedule. Costs and estimated earnings in excess of billings (underbillings) appear as a contract asset, and billings in excess of costs and estimated earnings (overbillings) as a contract liability.

What is Financial Reporting and Disclosures for CWIP?
On the balance sheet, CWIP appears within property, plant and equipment, either as its own line or in the notes as “construction in progress”. It is a noncurrent asset. In the notes, companies typically show:
- The CWIP balance at the start and end of the year, with additions and transfers to fixed assets.
- The amount of interest capitalized during the period.
- Significant commitments for capital projects that are signed but not yet performed.
- Any impairment recorded on projects that were abandoned or written down.
On the cash flow statement, payments for CWIP are investing cash flows, usually within capital expenditures.
What are the Challenges with CWIP?
- Cost allocation. Shared people, equipment and overhead have to be split between projects and between capital and expense, and the split has to hold up in an audit.
- Late transfers. Projects finish, the asset goes into use, and nobody transfers the balance. Depreciation starts late and the books understate expense.
- Stale balances. Small amounts left in CWIP after the main transfer, or projects paused indefinitely, sit on the balance sheet for years.
- Splitting into components. A single transfer to “building” ignores parts with shorter lives, such as HVAC or racking, and depreciates them too slowly.
- Estimates on contracts. For contractors, revenue depends on estimates of total cost, and weather, design changes and supply delays move those estimates.
What are a few Considerations with CWIP?
- Accurate tracking and documentation. Keep the invoice, timesheet or calculation behind every cost in CWIP, so an auditor can trace each dollar.
- Consistent policies. Apply the same rules for overhead, interest and component splits to every project.
- A clear in-service test. Decide what “ready for its intended use” means for each project before it finishes, such as a signed commissioning certificate.
- Risk review. Look at delayed and over-budget projects every quarter, and test for impairment when a project is in doubt.
What are the best Practices for Managing CWIP?
- Open one CWIP account or project code per project. A single shared CWIP account makes it impossible to say which costs belong to which asset.
- Charge costs against a budget. Compare spend with the approved capital budget every month, while there is time to act.
- Reconcile monthly. Make sure the CWIP subledger equals the general ledger balance.
- Review aging. List every project with no new costs in 90 days and ask whether it is finished, paused or abandoned.
- Transfer on the in-service date. Capitalize into fixed assets in the period the asset goes into use, not at year-end.
- Split into components at transfer. Create one asset record for each part with its own useful life, and tag each one so it can be found in the next count.
Once the assets are in the register, the fixed asset register guide covers how to record, depreciate and verify them.
How Asset Infinity Handles Construction in Progress
Asset Infinity’s fixed asset management software tracks construction in progress on the same register that holds your finished assets:
- Projects hold cost without depreciating it. Costs are added as invoices arrive and charged to a budget head.
- Budgets are checked as you spend. Budget heads show what was sanctioned, released, committed and spent, and capital requests start in a yearly planning round on the capital planning software page.
- Commissioning splits the total. When the project is commissioned, its cost is split across the assets it became, each with its own record.
- Depreciation starts in each book. Every new asset can be depreciated in more than one book, such as one for the financial statements and one for tax, and each period’s run is posted as journals for the general ledger.
Frequently Asked Questions
What is CWIP in accounting?
CWIP is a balance sheet account within property, plant and equipment that holds the costs of a long-term asset while it is being built. When the asset is ready for use, the balance moves to fixed assets and depreciation begins.
Is CWIP a fixed asset?
Yes. CWIP is a noncurrent asset reported within property, plant and equipment, but it is not depreciated until the asset is placed in service.
Is CWIP depreciated?
No. Depreciation starts when the asset is placed in service. A CWIP balance can still be written down if the project is abandoned or impaired.
What is the difference between CWIP and capital work in progress?
They are the same account. “Capital work in progress” is the more common name in India and some other countries, and “construction in progress” is more common in the US.
When is CWIP transferred to fixed assets?
When the asset is ready for its intended use, which is usually marked by commissioning, a certificate of occupancy or acceptance testing. The transfer should happen in that period, not at year-end.
