The Valuation Methods Buyers Actually Use

What goes into the number: Trade business valuations are built from three layers stacked on top of each other — earnings (SDE or EBITDA, depending on size) multiplied by a trade-specific range, an asset-floor adjustment for the trucks, equipment, and inventory the buyer takes over, and an owner-dependency discount that bites hardest at owner-operated shops. None of the layers is fixed; a sophisticated buyer blends all three to land on a number. Below is the menu of methods buyers reach for, the formula behind each, and when each one applies.

There is no single correct way to value a trade business. Buyers blend methods depending on your size, profitability, and deal structure. Here are the five that come up most often in trade business sales:

Most Common

Seller's Discretionary Earnings (SDE)

The go-to method for trade businesses under $2M revenue. SDE captures what the business actually puts in an owner's pocket — net profit plus owner salary plus legitimate add-backs run through the books.

SDE = Net Profit + Owner Salary + Add-backs
Mid–Large Operations

EBITDA Multiple

Used when your business has real management in place — you're not the lead tech, dispatcher, and bookkeeper rolled into one. EBITDA strips out financing and accounting decisions to show operating profitability.

EBITDA = Earnings before Interest, Taxes, D&A
Sanity Check

Revenue Multiple

The fastest but least accurate method. Revenue multiples don't account for margin, so 0.5× revenue on a 10% margin business is very different from 0.5× on a 25% margin business. Use as a sanity check only.

Value = Annual Revenue × Multiple (0.3–1.0×)
Floor Value

Asset-Based Valuation

The fair market value of everything the business owns: trucks, tools, inventory, equipment, optional real estate. The floor of any deal — no rational buyer pays less than liquidation value of what they're taking over.

Value = FMV(Equipment + Fleet + Inventory)
Most Accurate

Comparable Transactions

What similar trade businesses actually sold for in the last 6–24 months — region, revenue tier, license type, and structure. The most defensible number in any negotiation, and the hardest to access without specialist data. TradeReins uses closed-deal data across trades to inform its valuations.

Value = Median comp × your quality adjustment
How to choose a method: If your trade business is under $2M in revenue and you're still a working owner — start with SDE. If revenue is $2M+ and you have a real manager handling day-to-day — use EBITDA. Always cross-check against asset-based as your floor. Comparable transactions trump everything if you can get the regional closed-deal data.

Cross-Trade Multiples — What HVAC, Plumbing, Electrical, Roofing Actually Trade At

Generic small-business multiples are useless for trade businesses. The trades have their own benchmarks, shaped by recurring contract revenue, equipment intensity, license-transferability, and technician key-person risk. Here is the cross-trade reference table — ranges that map closely to the trade-specific guides elsewhere on this site:

Trade Typical Rev Range SDE Multiple EBITDA Multiple Revenue Multiple Typical Deal Size
HVAC (mid-market) $500K–$2M 2.0–3.5× 3.0–4.5× 0.4–0.7× $500K–$2M
HVAC (large) $2M+ 4.0–6.0× 0.6–1.0× $2M+
Plumbing (mid-market) $500K–$2M 2.0–3.0× 3.0–4.0× 0.4–0.7× $500K–$2M
Electrical (mid-market) $500K–$2M 2.0–3.0× 3.0–4.5× 0.3–0.6× $500K–$2M
Roofing (service-heavy) $500K–$2M 1.8–2.8× 2.5–3.5× 0.3–0.6× $500K–$2M

These are market ranges, not guarantees. Where you land within a band depends on the factors below.

What Pushes Your Multiple Up or Down

Two trade businesses with identical SDE can sell for very different prices. Here is what determines which end of the range you land on:

▲ Value Boosters

  • Recurring maintenance contracts (PM plans, service agreements) — adds 0.25–0.5× to the multiple
  • Commercial mix >40% of revenue — more stable than residential
  • License in the business entity — transferable on close, not owner-bound
  • Modern fleet — trucks under 5 years old, well-maintained
  • Owner can step back — operations run without the owner in the truck
  • Diversified customer base — no single customer >15% of revenue
  • Certified technicians (NATE, EPA 608, manufacturer)
  • Dispatch software, CRM, and documented SOPs in place
  • Strong review footprint (4.7+ across Google/Yelp)
  • Backlog of contracted work (12+ months visibility)

▼ Value Reducers

  • Owner dependency >30% — owner is the lead tech, estimator, and customer relationship
  • Severe seasonal concentration (80%+ of revenue in 3 months)
  • Single mix dependency (installation only — no recurring service book)
  • Customer concentration — top customer >30% of revenue
  • Fleet older than 8 years with deferred maintenance
  • Net margin under 15%
  • Messy books — personal expenses mixed with business
  • Owner-bound license — no transfer path without the owner's individual certification
  • Pending legal or compliance issues
  • Key employees likely to leave after sale
The plain-English summary rule: Take your SDE, multiply by 2.0–3.5× for the baseline. Add 0.25–0.5× if you have recurring contracts and low owner dependency. Subtract 0.25–0.5× if you are highly seasonal, owner-dependent, or have a single-customer concentration. That is the bracket a real buyer will walk in with — the asset floor (Section 3) sits underneath that bracket, not above it.

The Asset Floor — Why Fleet FMV Matters (Not Purchase Price)

For service trades the asset floor is the missing layer most owners get wrong. A buyer evaluates the trucks, tools, and inventory they will receive at close — not what you paid for them years ago. The asset floor is the number below which a deal cannot rationally close, because at that point the buyer is better off buying the assets at auction than buying the business.

The cleanest way to think about asset value: it is the floor for any trade business sale, and it comes up most often when earnings are thin or when the owner has under-invested in the operation. For a healthy trade business with strong SDE, the asset floor barely matters — but it always sits underneath the multiple-based valuation as the absolute minimum.

The single most common mistake: using purchase price instead of fair market value. The HVAC guide's "Mistake 1: Using Your Truck Purchase Price" framing applies across every trade — NADA guides and recent auction comps are the right source.

Asset Class Common Mistake Correct Treatment
Fleet (service trucks, vans) Using depreciated purchase price from the books Use NADA or recent auction comps for each vehicle at current mileage and condition
Equipment & Tools Including items no longer in service or fully depreciated FMV of equipment still actively in use — sheet-metal brake, recovery machine, diagnostic tools, specialty jigs
Inventory Counting parts at full retail as if new Inventory at liquidation-friendly value — typically 50–70% of retail for service-trades parts
How the asset floor plays in practice: A buyer will never pay below asset value — but they won't pay far above it either if earnings are thin. For a $2M-revenue HVAC shop with strong SDE, the asset floor ($150K–$300K in fleet and equipment) is essentially a non-event because earnings cover it many times over. For a struggling $400K-revenue shop with weak margins, that same asset floor may be the entire conversation.

Worked Example — A Real-Shape Phoenix-Metro HVAC Shop

The $1M–$3M lands for the cross-trade mid-market range. Here is how that bracket gets built, line by line, for a representative Phoenix-metro HVAC operation at $2M revenue — the kind of shop that drives past your house on a 110-degree afternoon. Numbers are illustrative for a typical owner-operated mid-market HVAC business; replace with your own.

Inputs
Revenue $2,000,000
SDE (21% margin) $420,000
Recurring PM contracts $640,000 (32%)
Fleet FMV (5 trucks) $180,000
Owner on tools ~30% of week
Multiple Range
SDE multiple (mid HVAC) 2.0–3.5×
Recurring contracts premium +0.5×
Owner dependency discount −0.3×
Net adjusted range 2.2–3.7×
Asset floor (FMV) $180,000
Expected Range
SDE × 2.2× (low) $924,000
SDE × 3.0× (mid) $1,260,000
SDE × 3.7× (high) $1,554,000
Owner-adjusted range $1.05M–$1.3M

A buyer walking into this shop with the cross-trade baseline (2.0–3.5× SDE = $840K–$1.47M) would apply a +0.5× premium for the strong recurring contract book, then a −0.3× discount for the owner still being on the tools. That lands the bracket at roughly $1.05M–$1.3M after both adjustments. The asset floor ($180K) is essentially irrelevant here — earnings cover it many times over.

Your shop's specific numbers will shift the bracket. Swap in your own revenue, SDE, contract share, fleet FMV, and owner involvement, and the same method lands on your number. Brackets at the bottom of trade-detail pages ($1M–$3M for a mid-market HVAC shop) come from applying these adjustments to the cross-trade mid-market baseline — actual close price still depends on buyer fit, license-transfer details, and structure (seller financing, earnout, trial period).

Why Owner-Dependent Shops Trade at a Discount

Owner-dependent trade businesses — where the owner is simultaneously the lead estimator, top tech, dispatcher on busy days, and the customer relationship that holds the book together — trade at a real discount. Buyers apply it because the Day-1 walk-out risk is real: if the owner falls ill, or simply decides three weeks after close that they do not want to ride along on the trial period anymore, the business contracts fast. Key-person risk is not a theoretical concern under these conditions — it is the central pricing question.

The Arizona example above shows the discount in plain numbers. With $640K in recurring contracts (32% of revenue) and an owner still on the tools 30% of the week, the baseline 2.0–3.5× range would ordinarily push toward the upper end. The −0.3× discount the buyer applies for owner involvement brings it back toward the middle. The mitigation is straightforward but not free: 18–24 months before sale, get out of the truck, promote a lead tech, write SOPs, and start transferring customer relationships from "the owner" to "the company." Each step reduces the discount.

Want to close the discount before you list? The Owner Exit Checklist walks through 50 questions across financial cleanup, license-transferability, fleet FMV, customer concentration, and owner-dependency reduction — the prep work that turns a baseline-multiple shop into a premium-multiple shop. Most of it takes 12–24 months and is recoverable in the final sale price many times over.

Valuation Questions, Answered Plainly

Click any question to expand. Answers are plain-language — including the cases where the actual multiple depends on specifics, where asset value trumps earnings, and where the "right" answer is to hire a CPA before you argue with a buyer.

SDE (Seller's Discretionary Earnings) is what the business puts in the owner's pocket — net profit plus the owner's salary plus legitimate add-backs like personal expenses run through the business. It is the right method for sub-$2M trade businesses where the owner still works in the business. EBITDA strips out financing, taxes, depreciation, and amortization to show operating profitability, which matters more for mid-to-large trade businesses with a real management layer where the owner is no longer a key tech. Buyers use SDE for small deals and EBITDA for larger ones — they measure different things and the multiple range is different. A $400K SDE on a mid-market HVAC shop is roughly a $1M–$1.4M sale; a $400K EBITDA on a larger operation can push closer to a $2.0M–$2.5M sale depending on management depth.
For trade businesses in the mid-market band ($500K–$2M revenue), the typical SDE multiple is 2.0–3.5× — meaning a $350K SDE shop usually trades at $700K–$1.2M. HVAC and plumbing tend to sit at the higher end of that band when recurring maintenance contracts and a licensed, stable crew are in place. Electrical is similar but license-tier sensitive — a Master-licensed operation with reliable commercial mix can hit 3.0× or better. Roofing tracks plumbing for service-heavy shops and can run below 2.0× for installation-heavy businesses with severe seasonal concentration. The cleanest way to read a trade business multiple is: baseline 2.0–3.5× SDE, plus 0.25–0.5× for recurring contracts and low owner dependency, minus 0.25–0.5× for severe seasonality, single-customer concentration, or owner-as-the-business.
Asset value is the floor of every trade business sale. Fleet FMV, equipment, tooling, and inventory are real, liquidatable assets a buyer takes over at close — a rational buyer will not pay less than the aggregate fair-market value of what they receive. For an HVAC shop with five trucks, a sheet-metal brake, recovered refrigerant inventory, and a stocked parts room, that floor often lands at $150K–$300K. The asset floor matters most when earnings are thin (a struggling shop that is still salable because the trucks and tooling are worth real money) and least when earnings are strong (the asset floor becomes nearly irrelevant because the buyer is paying for the income stream). Get the asset floor wrong by using purchase price instead of FMV and you will either overprice your shop by tens of thousands or leave money on the table at the negotiating table.
Owner-dependent trade businesses trade at a real discount — typically 0.3–0.7× off the multiple buyers would apply to a fully-managed shop with the same numbers. The discount covers key-person risk (the lead estimator, dispatcher, and senior tech is the same human, and if that human walks Day 1 the business shrinks), customer-relationship concentration (the buyers and suppliers pick up the phone when the owner calls, not anyone else), and Day-1 walk-out risk (what happens if the owner gets hurt the week after close). The mitigation: 18–24 months before sale, get out of the truck, promote a lead tech, write SOPs, and start transferring customer relationships to the company rather than the owner. Each one of those steps reduces the discount — owners who do the prep work routinely close at the high end or above the baseline multiple.
Profit (specifically SDE or EBITDA, depending on size) is what drives the multiple — revenue is the sanity check, not the headline. Two trade businesses with the same $2M revenue can have radically different values: one with a 10% margin and weak dispatch falls into the bargain tier, the other with a 22% margin and a sticky maintenance contract book trades at a premium. The reason: buyers are paying for the cash flow the business will produce under new ownership, and a 10% margin shop produces less of it. Revenue multiples work as a quick reference (0.3–1.0× for service trades, with HVAC and plumbing at the higher end when margins are healthy) but they are not what a sophisticated buyer builds their offer on.
