Here’s a step-by-step guide to calculating COGS in construction:
A. Basic Formula
The basic formula for calculating COGS in construction is:
COGS = Beginning Inventory + Purchases – Ending Inventory
However, this formula needs to be adapted to the construction context, where “inventory” often refers to materials and supplies rather than finished goods.
B. Step-by-Step Calculation Process
- Determine the beginning inventory:
- This includes any materials on hand at the start of the accounting period.
- For ongoing projects, include the value of work-in-progress.
- Add purchases made during the period:
- Include all materials and supplies bought for specific projects.
- Factor in any bulk purchases allocated to multiple projects.
- Calculate direct labor costs:

- Permits and licenses obtained for particular jobs.
- Project-specific insurance.
- Determine the ending inventory:
- Account for any unused materials at the end of the period.
- Include the value of work-in-progress for ongoing projects.
- Apply the formula:
COGS = Beginning Inventory + Purchases + Direct Labor + Subcontractor Costs + Other Direct Costs – Ending Inventory
C. Example Calculation
Let’s walk through a simplified example:
Assume a construction company is working on a home renovation project over a one-month period.
- Beginning inventory: $5,000 (materials on hand)
- Purchases: $20,000 (materials bought for the project)
- Direct labor: $15,000 (wages for carpenters, electricians, etc.)
- Subcontractor costs: $8,000 (for specialized work like HVAC installation)
- Other direct costs: $2,000 (equipment rental and permits)
- Ending inventory: $3,000 (unused materials)
COGS = $5,000 + $20,000 + $15,000 + $8,000 + $2,000 – $3,000 = $47,000
In this example, the COGS for this project over the one-month period is $47,000.
D. Considerations for Accurate COGS Calculation
- Job costing: Implement a job costing system to track costs for each project separately.
- Consistent method: Choose either the cash or accrual accounting method and apply it consistently.
- Work-in-progress: For projects spanning multiple accounting periods, accurately value and account for work-in-progress.
