How to Calculate Percentage of Completion

The Percentage of Completion (POC) method is a fundamental accounting approach used for long-term contracts, allowing businesses to recognize revenue and expenses gradually as work progresses. This provides a more accurate representation of a company’s financial performance over the duration of an extended project. Its primary purpose is to align revenue and expense recognition with the actual progress, offering a consistent and transparent view of financial results throughout the contract’s life. This avoids significant fluctuations in reported income that would occur if all revenue and expenses were recognized only at project completion. Companies in construction, aerospace, and large software development frequently use this method, which the IRS generally requires for long-term contracts exceeding certain thresholds.

Gathering Essential Information

Before any percentage of completion calculation can begin, a business must gather several critical data points. The accuracy of these inputs directly influences the reliability of financial reporting.

A primary input is the estimated total project costs, encompassing all projected expenditures from inception to completion. This includes direct costs like labor, materials, and subcontracted services, as well as allocated indirect costs. Developing these estimates requires understanding the project scope and collaboration between project management, engineering, and finance teams.

Equally important are the actual costs incurred to date, representing expenses accumulated as the project progresses. These costs must be tracked precisely and recorded timely. Regular reconciliation against budgets is essential to identify deviations and ensure calculation accuracy.

Another vital piece of information is the estimated total project revenue, the total expected income from the contract. This often includes the initial contract price and anticipated revenue from approved change orders or claims. Determining this estimate requires reviewing contract terms and conditions.

Other inputs may be necessary depending on the method chosen for determining completion. For instance, some methods rely on total estimated labor or machine hours compared to actual hours expended. Contracts involving discrete deliverables might track total estimated units against actual units delivered. These provide alternative measures of progress when cost alone may not be the most appropriate indicator.

The reliability of the percentage of completion method is directly tied to the accuracy and regular updating of these estimates and actuals. Businesses must establish processes for periodic review and revision of estimates as new information becomes available or project conditions change. This diligence ensures financial statements reflect the most current assessment of project progress and profitability.

Methods for Determining Completion

The core of the percentage of completion method lies in accurately determining how much of a project has been completed. Several recognized methods exist, each suited to different types of long-term contracts and project characteristics. The chosen method should consistently represent the progress of the work.

Cost-to-Cost Method

The cost-to-cost method is widely used, particularly in construction. This approach measures progress by comparing actual costs incurred to date against the total estimated costs for the entire project. The formula is: (Actual Costs Incurred to Date / Estimated Total Project Costs) x 100.

For example, a contract with an estimated total cost of $800,000. If $200,000 in costs have been incurred, the project is 25% complete ($200,000 / $800,000 = 0.25). If cumulative actual costs reach $600,000, the project would be 75% complete ($600,000 / $800,000 = 0.75). This method assumes a direct relationship between costs incurred and progress made.

Efforts-Expended Method

The efforts-expended method is often appropriate for service-oriented contracts, such as engineering or software development. This method measures completion based on the proportion of effort expended to date compared to the total estimated effort required. Efforts can be quantified using metrics like labor hours or machine hours.

For instance, if a software development project is estimated to require 10,000 total labor hours, and 3,000 hours have been expended, the project is 30% complete (3,000 hours / 10,000 hours = 0.30). If another 4,000 hours are expended, cumulative effort reaches 7,000 hours, indicating 70% completion (7,000 hours / 10,000 hours = 0.70). This approach is effective when labor or machine time drives project progress.

Units-of-Delivery Method

The units-of-delivery method applies when a contract involves the production or delivery of discrete, measurable units. This method calculates completion by dividing units delivered to date by the total estimated units to be delivered.

As an illustration, consider a contract to manufacture 1,000 specialized components. If 300 units have been manufactured and delivered, the project is 30% complete (300 units / 1,000 units = 0.30). If an additional 400 units are delivered, bringing the cumulative total to 700 units, the project would be 70% complete (700 units / 1,000 units = 0.70). This method is straightforward when project progress ties directly to producing uniform items.

The selection of the most suitable method depends on industry practice, reliability of estimates, and contract terms. The chosen method must provide a consistent and accurate depiction of performance and the transfer of control of goods or services to the customer. Businesses should apply the method that best reflects the progress toward satisfying their performance obligations.

Applying the Percentage to Financial Reporting

Once the percentage of completion is calculated, it’s applied to total estimated contract revenue and costs. This determines the amounts recognized in financial statements for the current period. This process ensures that revenue and expenses are matched to the work performed, providing a more accurate view of profitability over the life of the project.

For revenue recognition, the calculated percentage is multiplied by total estimated contract revenue to get cumulative recognized revenue. Any revenue recognized in prior periods is subtracted to find the current period’s revenue. For example, if a project has $1,000,000 total estimated revenue and is 25% complete, $250,000 ($1,000,000 x 25%) would be recognized.

Similarly, a corresponding portion of estimated total costs is recognized, adhering to the matching principle. This involves multiplying the percentage of completion by estimated total project costs for cumulative costs. Prior period costs are deducted to arrive at current period costs. This systematic recognition ensures the gross profit margin is consistently applied.

The method impacts both the income statement and balance sheet. On the income statement, recognized revenue and costs affect gross profit and net income, smoothing out earnings and preventing large, infrequent profit spikes.

On the balance sheet, contract assets and contract liabilities present the financial position. Contract assets arise when costs incurred and recognized profits exceed amounts billed, representing a company’s right to consideration. Contract liabilities occur when billings exceed costs and recognized profits, representing deferred revenue or an obligation.

These calculations are typically performed periodically, often quarterly or annually. As projects progress, estimates for total costs and revenues are continuously reviewed and updated. Changes in estimates necessitate a cumulative catch-up adjustment in the current period, ensuring cumulative recognized revenue and costs reflect updated information.
