Construction Company Valuation: What Is It Worth?
A commercial construction subcontractor is usually worth 2.5x to 4.5x EBITDA. The multiple, not the revenue, drives the number. Clean job-costed books, an owner who is not the business, and no single customer over 25 percent push you to the high end. Messy books and owner dependence pull you to the low end.
If you want to know what your construction business is worth, the answer is a multiple of profit, not a slice of revenue. This page explains how subcontractors are valued, the 2.5x to 4.5x range and what moves you across it, and a calculator to estimate your own number.
The Multiple, Not The Revenue.
Business valuation for a construction company is the price a buyer will pay, calculated as adjusted EBITDA multiplied by a market multiple that reflects risk. Revenue does not set the price. A buyer pays for provable, repeatable profit they can keep after you leave.
Two subs with identical revenue can be worth millions apart. The one with three years of clean job-costed financials, a team that runs jobs without the owner, and diversified customers sells near the top of the range. The one with commingled books and a single GC at half of revenue sells near the bottom, if it sells at all. The gap between those multiples is the real money, and it is built over years, not weeks.
Add-backs are where deals are won or lost. The owner truck, the family member on payroll who does not work, the personal travel run through the company, all of it has to be cleanly documented to add back to EBITDA. If the books are commingled, the buyer disallows the add-backs and the multiple applies to a smaller number.
2.5x To 4.5x EBITDA.
Commercial construction subcontractors typically sell for 2.5x to 4.5x EBITDA. Three factors move you across that range.
Clean job-costed books that survive diligence push the multiple up. An owner who is the business pulls it down, because the buyer is buying a job, not a company. A single customer over 40 percent of revenue pulls it down hard, because the buyer assumes the relationship walks when you do. Diversify under 25 percent per customer and the discount goes away.
Run Your Number.
Enter your revenue, your net profit margin, and the multiple you think you would earn. The calculator shows your EBITDA and your valuation, plus the full range from a low-trust 2.5x to a high-trust 4.5x. The spread between those two is what clean financials and owner independence are worth.
Estimate Your Business Value
Enter your numbers. The result updates as you type. Nothing is saved or sent.
The clean-books spread: moving from 2.5x to 4.5x on this business is worth $1M. That is what three clean years and owner independence are worth at sale.
A planning estimate, not a formal valuation. Real EBITDA includes documented add-backs, and the multiple depends on diligence findings, backlog quality, and deal structure. Use it to see what moves the number, then get a real opinion of value before going to market.
Same Revenue. Double The Value.
A $13.5M marine GC moved from a $2.3M valuation to $5.5M in nine months, same revenue and same crews, by taking net profit from 7 to 14 percent on clean documented books. Nothing about the work changed. The buyer could finally see and trust the profit, so the multiple went up and the profit it applied to went up with it.
The CFOS target build is a $7.8M valuation at $12M revenue: 12 percent net profit, 9 to 13 percent overhead, zero debt, and $650K always in the bank. The Construction CFO installs the financial system that makes that number provable, which is the version a buyer pays the top multiple for.
