What is overhead allocation in restoration? Overhead allocation is the practice of distributing the company’s indirect costs — facility, administrative staff, software, vehicles, insurance, ownership salary — across individual jobs so that each job bears its share of the total cost of running the business. Without overhead allocation, job-level gross margin is a misleading number because it ignores the fixed cost layer every job must cover.
A restoration company quotes a water mitigation job at $8,500 with an expected gross margin of 42 percent. The job runs clean. Labor comes in at budget. Materials and equipment land on target. Subcontractor work is minimal. The owner looks at the close-out report and sees a 42 percent gross margin, just as forecast.
The job did not actually make 42 percent. It made something less than that — because none of the overhead the company runs on a monthly basis is reflected in the gross margin calculation. The facility rent, the accounting staff, the dispatcher, the software subscriptions, the vehicles, the insurance, the owner’s compensation — all of that is absorbed at the P&L level, not at the job level. Which means the 42 percent gross margin is the starting point, not the ending point.
Restoration companies that do not allocate overhead to jobs make strategic decisions on the wrong number. They accept program work that looks profitable at the gross margin line and is not profitable at the fully-loaded level. They expand service lines that look contributive and are actually dilutive. They price jobs based on a margin model that leaves the overhead contribution to chance.
What Overhead Allocation Actually Does
Overhead allocation is the accounting practice of distributing the company’s indirect costs — the ones not directly attributable to a specific job — across all jobs in a systematic way. The goal is to produce a fully-loaded job-level cost number that reflects what it really costs the company to deliver each job, not just the variable costs.
The mechanics are straightforward. Calculate the company’s total annual overhead — every cost that is not direct labor, direct materials, direct equipment, or direct subcontractor cost. Divide that number by the company’s annual revenue (or some other allocation base such as direct labor hours or direct cost). The result is an overhead rate, typically expressed as a percentage, that gets applied to every job.
If a company has $750,000 in annual overhead and $5 million in annual revenue, the overhead rate is 15 percent. Every job the company runs is carrying that 15 percent load. The water mitigation job quoted at $8,500 is allocating $1,275 to overhead before any profit drops to the bottom line. Gross margin of 42 percent — $3,570 — turns into a contribution after overhead of $2,295. A very different number.
Why Most Restoration Companies Skip This
Overhead allocation is one of those financial disciplines that feels complicated on day one and obvious after six months. Most restoration companies never get to day one for two reasons.
The first is that overhead allocation adds a step to every job cost calculation, and without a clear protocol it becomes one more thing the ops team does not have time for. If it is not systematized, it does not happen.
The second is cultural. Restoration owners who grew up in the trade tend to think about jobs in terms of direct cost — labor, materials, equipment, subs. Allocated overhead feels like an accounting abstraction that does not reflect “real” operating cost. The feeling is understandable. The consequence is that the decisions made without allocated overhead are decisions made on a partial number.
What You Need to Calculate the Rate
Calculating a defensible overhead rate requires a clean view of the company’s fixed cost structure. The categories typically included in overhead are:
Facility costs — rent, utilities, property maintenance for offices, shops, and warehouses.
Administrative staff — accounting, dispatch, office management, executive assistance, and any other non-billable staff.
Software and technology — job management systems, accounting systems, CRM, estimating platforms, and infrastructure.
Vehicles and fleet — payments, insurance, fuel, and maintenance for any vehicles not directly assigned to a billable crew.
Professional services — accounting, legal, banking, insurance brokerage fees.
Ownership compensation — the portion of owner salary and benefits not directly tied to billable work.
Marketing — website, content, advertising, sponsorships, and related spend.
Indirect equipment — equipment held in inventory that is not directly allocated to jobs.
General insurance — liability, workers’ comp allocations not captured in burdened labor, umbrella coverage.
Sum those categories across a trailing twelve months. Divide by annual revenue (the simplest base) or by direct labor hours (more sophisticated, better for labor-intensive operations). The result is the rate you allocate to every job going forward.
How It Changes Decisions
Once overhead is allocated at the job level, a different picture of the business emerges.
Jobs that looked profitable on gross margin turn out to be barely contributing after overhead. Service lines that looked like growth opportunities turn out to be underwater at the fully-loaded level. Program work that was accepted at attractive gross margin turns out to be losing money once the compliance overhead is included. Categories of residential work that felt marginal turn out to be the most profitable segment in the business.
None of these observations are possible without allocated overhead. With it, strategic decisions sharpen. Pricing moves in categories where the fully-loaded margin is too thin. Program contracts get renegotiated when the number comes up for review. Service line investment shifts toward the segments producing real contribution. Over a year or two, the company’s margin trend moves — not because anything dramatic happened, but because the decisions got better.
Overhead Allocation and the Post-Mortem
Overhead allocation pairs directly with the every-job post-mortem. The post-mortem reviews estimated-vs-actual margin on every closed job. If the margin numbers on the report are gross only, the review is working with a partial picture. If they are fully-loaded — gross margin minus allocated overhead — the review sees what the company is actually earning on each job.
This is the difference between a post-mortem that produces operational lessons and a post-mortem that produces financial strategy. Operational lessons come from gross-level data. Financial strategy comes from fully-loaded data.
A company serious about compounding installs both the overhead allocation and the post-mortem, and uses them together.
Common Mistakes
A few consistent mistakes show up when companies install overhead allocation for the first time.
Wrong allocation base. Using revenue as the allocation base is simple but can distort results when different service lines have very different revenue-to-labor ratios. Using direct labor hours is often better for labor-intensive work. Using direct cost is sometimes the cleanest base overall. Pick the base that reflects the actual driver of overhead consumption in the specific company.
Static rate never updated. The overhead rate calculated at the start of year one is almost certainly wrong by year three. Overhead grows. Revenue mix shifts. The rate needs to be reviewed and recalibrated at least annually and ideally quarterly for fast-growing companies.
Allocated too aggressively. Including costs in overhead that should be direct — for example, putting project management time in overhead when it should be allocated to specific jobs — inflates the rate and distorts every job’s margin picture. Define the direct/indirect boundary carefully.
Used as a finance exercise, not an operating practice. If the overhead rate lives in the CFO’s spreadsheet and never shows up on a job cost report, it has no effect on the company. Integrating allocated overhead into the live job cost data is what makes the practice operationally useful.
Where to Start
If overhead is not currently allocated at the job level in your company, start with the trailing twelve months.
Pull the P&L. Identify every cost that is not directly tied to a specific job. Sum those categories. Calculate the rate as a percentage of revenue. Apply that rate to the last fifty closed jobs and recalculate job-level margin on a fully-loaded basis.
The pattern that emerges will tell you where the real profitability is in the business — and where it is not. Some of what you find will be uncomfortable. All of it will be more useful than the gross-margin-only picture you were working from before.
Integrate the allocated overhead into every future job cost report. Recalibrate the rate quarterly for the first year, then annually. Use the fully-loaded numbers in the weekly post-mortem and in every strategic pricing or program decision.
Within two quarters, the company starts making different decisions. Within a year, the margin trend reflects it.
Frequently Asked Questions
What is overhead allocation in a restoration company?
The practice of distributing indirect costs — facility, administrative staff, software, vehicles, insurance, ownership compensation, marketing, professional services — across individual jobs through a calculated overhead rate, producing a fully-loaded cost number for each job.
Why does overhead allocation matter?
Because job-level gross margin without allocated overhead is a misleading number. Strategic decisions about pricing, service mix, and program acceptance made on gross margin alone often move the company in the wrong direction once the overhead layer is included.
What is a typical overhead rate for restoration companies?
Typically 15 to 25 percent of revenue for mid-sized restoration companies, though the correct rate for a specific company depends on its cost structure, scale, and operating model. The rate should be validated against the company’s actual trailing overhead, not benchmarked against industry averages.
What allocation base should I use?
Revenue is the simplest and works well for most restoration companies. Direct labor hours is better for labor-intensive operations where labor is the primary driver of overhead consumption. Direct cost is the cleanest academic base but requires more sophisticated tracking. Pick the base that reflects the actual cost driver in your operation.
How often should the overhead rate be updated?
At least annually. For fast-growing companies or companies undergoing material changes in service mix, quarterly review is appropriate. A stale rate produces decisions based on outdated cost structure and quietly drifts the company’s margin picture.
Do I need sophisticated accounting software to allocate overhead?
No. The rate calculation is arithmetic. Applying the rate to each job cost report is a formula. The discipline matters more than the software — a spreadsheet-driven practice run consistently produces better results than an expensive system that no one uses.
