Typical Overhead Percentages for HVAC and Plumbing Contractors: A Financial Guide
Discover the industry benchmarks for HVAC and plumbing overhead. Learn how to calculate your breakeven point using GAAP and WA State regulations.
Quick Answer: For HVAC and plumbing contractors, typical overhead percentages range between 25% and 40% of total revenue. However, for a business to maintain healthy profitability, net profit margins should be targeted at 10-15%, often requiring a gross margin of 45-50% to cover fixed costs. Under GAAP (ASC 606), overhead must be meticulously tracked to distinguish between direct job costs and general administrative expenses.
What Defines Overhead in HVAC and Plumbing?
In the mechanical contracting world, overhead represents the costs required to keep the doors open, regardless of whether a technician is currently on a job site. For accounting purposes, overhead is generally bifurcated into two categories: variable overhead and fixed (G&A) overhead.
According to GAAP (ASC 225-10), these costs are periodic and are not directly traceable to a specific customer contract. For an HVAC or plumbing firm, this includes:
Under IRS Publication 535, Business Expenses, these costs are deductible if they are ordinary and necessary for the operation of the trade or business.
What is the Typical Overhead Percentage for the Industry?
National benchmarks for the mechanical trades suggest that overhead typically consumes 25% to 40% of gross revenue.
How Does GAAP Distinguish Between COGS and Overhead?
A common mistake in HVAC bookkeeping is misclassifying "unapplied labor." Under ASC 606 (Revenue from Contracts with Customers), only costs directly related to fulfilling a contract should be capitalized as Cost of Goods Sold (COGS).
Failure to separate these prevents a contractor from knowing their true "Breakeven Hourly Rate."
What are the Mandatory Regulatory Costs in Washington State?
For HVAC and plumbing contractors operating in Washington, overhead is heavily influenced by state-specific mandates. These are non-negotiable fixed costs that must be factored into your percentage:
Why is the "Breakeven Plus" Formula Critical for Pricing?
To cover an overhead of 35%, a contractor cannot simply add 35% to their labor and materials. This is a common mathematical error.
If your overhead is 35% and you want a 15% net profit, your total "Load" is 50%.
The AIA Document G702 (Application and Certificate for Payment) often requires a breakdown of costs that forces commercial contractors to realize these margins clearly.
How Do Vehicle and Equipment Costs Factor In?
HVAC and plumbing are equipment-intensive. The IRS allows for the recovery of these costs through depreciation. Under Internal Revenue Code Section 179, contractors may elect to expense the full purchase price of qualifying equipment (service vans, heavy tools) in the year it is placed in service, rather than depreciating it over years.
However, for internal management reporting, the "operating cost per mile" should be tracked as a variable overhead component to ensure the fleet isn't silently eroding the net profit margin.
What is the Impact of Revenue Recognition on Overhead Tracking?
For larger mechanical projects, the Percentage of Completion (POC) method is required under ASC 606. This method matches revenue earned against costs incurred in a specific period.
If overhead is not properly allocated, a contractor might show an artificial "over-billing" or "under-billing" situation on the balance sheet. According to AICPA Audit and Accounting Guide for Construction Contractors, consistent allocation of indirect costs is vital for accurate financial reporting and bonding capacity.
The Bottom Line
Understanding your overhead percentage is the difference between "trading dollars" and building a scalable HVAC or plumbing enterprise. If your overhead is 35% and you are only marking up your jobs by 30%, you are losing 5% on every call you take. Consistent tracking of unapplied labor per ASC 606 and adherence to Washington RCW 82.04 tax obligations are the pillars of a financially sound mechanical contracting business.

FAQ
Q: Is marketing considered a direct cost or overhead?
A: Marketing is considered a General and Administrative (G&A) overhead expense. It cannot be tied to a specific contract fulfillment under ASC 606 guidelines.
Q: How often should I recalculate my overhead percentage?
A: At minimum, quarterly. However, under GAAP ASC 225, significant changes in business structure (like adding three new trucks) require an immediate budget review to adjust the "burdened" labor rate.
Q: Does Washington State B&O tax count as overhead?
A: Yes. Because it is a tax on gross receipts and not a pass-through sales tax, it is an operating expense (overhead) for the business (Source: RCW 82.04.220).

What Are the Financial Implications of Typical Overhead Percentages for HVAC and Plumbing Contractors for Contractors?
The financial impact of typical overhead percentages for hvac and plumbing contractors extends far beyond simple compliance. For general contractors and subcontractors alike, proper management directly affects cash flow, bonding capacity, and overall project profitability. According to the Construction Financial Management Association (CFMA), companies that implement rigorous financial controls see an average 15-20% improvement in project margins (Source: CFMA, Annual Financial Survey of the Construction Industry).
Cash flow management is particularly critical in construction, where payment cycles often extend 60-90 days. Contractors who fail to properly track and manage their finances risk running into liquidity issues that can jeopardize active projects. The percentage-of-completion method, required by GAAP for long-term contracts, provides the most accurate picture of financial performance but requires disciplined tracking (Source: GAAP, ASC 606 - Revenue from Contracts with Customers).
For Washington State contractors specifically, financial mismanagement can result in bond claims, license suspension, or even criminal penalties under RCW 18.27. The Department of Labor & Industries requires contractors to maintain adequate financial records and report accurately on all projects (Source: Washington State RCW 18.27 - Registration of Contractors).

Frequently Asked Questions
Is marketing considered a direct cost or overhead?
Marketing is classified as General and Administrative (G&A) overhead because it cannot be directly attributed to the fulfillment of a specific customer contract under ASC 606.
What is the 'Labor Burden' and is it overhead?
The "Burdened Labor Rate" includes the base hourly wage plus the costs of taxes (FICA, FUTA, SUTA), Workers' Comp (RCW 51.16), and benefits. This ensures that the 'cost' of an employee includes the overhead they generate.
Can I get in trouble for classifying overhead incorrectly?
Yes, failing to account for unapplied labor (non-billable time) is a violation of GAAP ASC 606-10 if you are capitalizing those costs as direct job costs. It should be recorded as overhead.
