What is the Percentage of Completion Method?
The percentage of completion method is an accounting practice used for long-term contracts, allowing for the recognition of revenue and profit in proportion to the work completed in each accounting period. Instead of waiting until a project is fully delivered, which could take several years, companies can report their financial performance as the project progresses. This approach, which is crucial for understanding how to calculate gross profit using percentage of completion method, provides a more accurate and timely picture of a company’s financial health during extended projects. It is widely used in industries like construction, aerospace, and large-scale software development where projects span multiple financial years.
This method is essential for any business engaged in long-term projects to comply with revenue recognition principles under both GAAP (ASC 606) and IFRS 15. The core idea is to match revenues with the expenses incurred to generate them within the same accounting period, avoiding the distortion of financial statements that would occur if all revenue was recognized at the very end of a multi-year project.
Percentage of Completion Method Formula and Mathematical Explanation
The most common approach to implement this method is the cost-to-cost basis. The logic is straightforward: the proportion of costs incurred to date out of the total estimated costs reflects the proportion of the project that is complete. This percentage is then applied to the total contract revenue to determine how much revenue can be recognized. Learning how to calculate gross profit using percentage of completion method involves a few key steps.
- Calculate the Percentage of Completion: This is the ratio of costs incurred so far to the total estimated costs.
- Calculate Total Estimated Gross Profit: This is the difference between the total contract value and the total estimated project costs.
- Calculate Recognized Revenue to Date: Multiply the percentage of completion by the total contract value.
- Calculate Recognized Gross Profit to Date: Multiply the percentage of completion by the total estimated gross profit. This is the ultimate goal of the calculation.
These steps provide a systematic way to recognize profit incrementally, aligning financial reporting with project progress.
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Total Contract Value | The total revenue agreed upon for the project. | Currency ($) | $100,000 – $100,000,000+ |
| Total Estimated Cost | The full projected cost to complete the project. | Currency ($) | Varies; typically 70-95% of contract value. |
| Costs Incurred to Date | The sum of all costs spent on the project so far. | Currency ($) | $0 to Total Estimated Cost |
| Percentage Complete | The proportion of the project finished, based on costs. | Percentage (%) | 0% to 100% |
Practical Examples (Real-World Use Cases)
Example 1: Mid-Sized Construction Project
A construction firm, “BuildRight Inc.”, has a contract to build a small office building for a total price of $5,000,000. The company estimates the total cost of the project will be $4,000,000. At the end of the first year, BuildRight has incurred $1,000,000 in costs.
- Percentage Complete: $1,000,000 / $4,000,000 = 25%
- Total Estimated Gross Profit: $5,000,000 – $4,000,000 = $1,000,000
- Recognized Revenue: 25% * $5,000,000 = $1,250,000
- Recognized Gross Profit: 25% * $1,000,000 = $250,000
For its first-year income statement, BuildRight will report $1,250,000 in revenue and $1,000,000 in costs, resulting in a gross profit of $250,000. This is a clear application of how to calculate gross profit using percentage of completion method.
Example 2: Large-Scale Software Development
A tech company, “Innovate Solutions,” signs a $10,000,000 contract to develop a custom enterprise resource planning (ERP) system over three years. The total estimated cost is $8,000,000. After year two, they have spent $6,000,000 in development costs.
- Percentage Complete: $6,000,000 / $8,000,000 = 75%
- Total Estimated Gross Profit: $10,000,000 – $8,000,000 = $2,000,000
- Recognized Revenue to Date: 75% * $10,000,000 = $7,500,000
- Recognized Gross Profit to Date: 75% * $2,000,000 = $1,500,000
By the end of year two, Innovate Solutions would recognize a cumulative gross profit of $1,500,000. If they had already recognized profit in year one, they would subtract that amount to find the profit for the current year. This demonstrates the cumulative nature of the calculation.

Key Factors That Affect Percentage of Completion Results
The accuracy of this method hinges on the quality of your estimates. Several factors can significantly impact the results:
- Accuracy of Cost Estimates: This is the most critical factor. If the total estimated cost is wrong, every calculation will be skewed. Underestimating costs can lead to overstating profit early on, which requires painful corrections later.
- Change Orders: Scope changes from the client that alter the contract value or costs must be promptly incorporated into your estimates to maintain accuracy.
- Cost Overruns: Unexpected increases in material prices, labor costs, or project delays can increase the total estimated cost, which in turn reduces the percentage of completion and recognized profit.
- Timing of Cost Incurrence: Front-loading costs (e.g., buying all materials upfront) can inflate the percentage of completion early in the project, even if the actual construction or development work hasn’t progressed as much. This is a known limitation of the cost-to-cost method.
- Project Delays: Delays can lead to increased overhead costs that must be factored into the total estimate, impacting profitability. A useful resource is our article on construction project accounting.
- Reliable Progress Measurement: While the cost-to-cost method is common, it’s vital to ensure that costs truly represent progress. Sometimes, other methods like labor hours or units delivered might be more appropriate.
Frequently Asked Questions (FAQ)
It should be used for long-term contracts where estimates of cost and progress can be made reliably and the client’s payment is reasonably assured. It is required under GAAP and IFRS for recognizing revenue over time for such contracts.
The percentage of completion method recognizes revenue as work progresses, while the completed contract method defers all revenue and profit recognition until the project is 100% complete. The latter is simpler but provides a less timely view of financial performance and is only allowed for short-term projects.
If your total estimated cost changes, you must update your calculations immediately. The change is applied prospectively. For example, if the estimated cost increases, the percentage of completion will decrease, and you will recognize less profit in the current and future periods. Understanding how to calculate gross profit using percentage of completion method means constantly refining estimates.
Yes. Since the method relies on management’s estimates, there is a risk of manipulation by either underestimating total costs or inflating the costs incurred to date to show higher profits. Strong internal controls and regular audits are necessary to mitigate this risk.
No. Recognizing revenue is an accounting concept for the income statement. It does not mean you have billed the client or received the cash. Managing cash flow by aligning billing schedules with project milestones is a separate but equally critical task. To learn more, read about the cost-to-cost method calculator.
Besides the cost-to-cost approach, companies can use the efforts-expended method (based on labor hours) or the units-of-delivery method (based on physical units completed, like houses in a development). The chosen method should best reflect the actual progress of the project.
It’s crucial for accurate financial reporting, securing financing, and making informed management decisions. It provides stakeholders, such as investors and lenders, with a realistic view of a company’s performance on long-term projects.
For US tax purposes, the IRS generally requires the percentage-of-completion method for long-term construction contracts, though some exceptions exist for smaller contractors. Consult our ASC 606 guide for more information on accounting standards.
