How to Value a Home-Services Business (the Method Buyers Actually Use)

If you’re asking “what is my business worth,” here is the direct answer: a home-services business is valued as seller’s discretionary earnings (SDE) times a market multiple, adjusted for risk. Broker-published ranges put most owner-operated shops between 2.0x and 3.5x SDE. BizBuySell’s 2025 year-in-review data shows an average cash flow multiple of 2.61x across small businesses sold, a median sale price of $350,000, and businesses selling at 94 percent of asking. Last verified August 1, 2026.

That’s the formula. It takes ten minutes.

What takes longer, and what this post is really about, is the adjustments. Two shops with identical SDE can sell $300,000 apart because of five factors that never show up on a P&L. Buyers score them every time. Most sellers have never seen the list.

We’ll do the whole method in three steps, structured exactly like the calculator we’re building, with one worked example carried all the way through.

Step 1: Compute your SDE

SDE is what the business actually generates for one owner-operator, before the owner’s own decisions muddy the picture. Start with net profit on your tax return and add back:

Two rules buyers enforce hard: every add-back needs a paper trail, and “the business also pays for my…” claims without documentation get struck. A struck add-back at a 2.5x multiple costs you 2.5x its value off the price.

If your business is big enough that a buyer would keep a general manager in place, they’ll value it on EBITDA instead of SDE, and the two numbers can differ by a manager’s salary times the multiple. That boundary matters enough that we wrote it up separately in SDE vs EBITDA for owner-operators.

Step 2: Pick the multiple

Multiples for home-services businesses cluster by size and by who’s buying. Broker-published ranges, last verified August 1, 2026:

For calibration: ClearlyAcquired’s 2026 analysis of BizBuySell HVAC transactions from 2021 through 2025 puts the median at 2.58x with quartiles at 1.99x and 3.33x. That quartile spread, roughly 1.3x wide, is the adjustment zone. On $300,000 of SDE it’s a $400,000 swing between the bottom and top of the same table row.

Where your trade lands inside these ranges, and why HVAC prices differently from coatings or fencing, is its own post: what home-services businesses actually sell for.

Step 3: Apply the adjustments

This is the longest section on purpose. The multiple table tells you the range. These five factors tell you where in the range a buyer will land, and they’re scored in every serious diligence process we’ve seen.

Owner-dependency: can it run four weeks without you?

The single biggest adjustment. A buyer is not buying your business; they’re buying the business that exists after you leave.

The test is concrete: if you took four weeks off with your phone off, what breaks? If the answer is “nothing, my ops manager runs the board and my crew leads close out their own punch lists,” you’re arguing for the top of the range. If you personally sell every job, price every job, and untangle every scheduling conflict, the buyer is pricing in the cost of replacing you, and that comes off the multiple, not just the price.

Owner-dependency is also the reason SDE and EBITDA diverge, which is why buyers ask about it before they ask about revenue.

Revenue mix: recurring agreements vs one-shot installs

A dollar of maintenance-agreement revenue is worth more than a dollar of one-shot install revenue, because the buyer knows it comes back next year without a salesperson touching it.

Install-heavy businesses (coatings, fencing, pools, decks) start every January at zero. That’s not fatal, buyers understand the model, but a shop that has converted even 15 to 25 percent of revenue to recurring service agreements reads as lower-risk and prices toward the top of its range. If you’re install-only, a documented referral engine and a deep repeat-customer list are the next best evidence.

Customer concentration

If any single customer is more than 10 percent of revenue, expect the question. More than 20 percent, expect a price adjustment or an earnout tied to that account surviving the transition.

This hits commercial-facing shops hardest: a residential coatings company with 400 customers a year has no concentration story to tell, while a facilities vendor with three property-management contracts is, in a buyer’s eyes, three phone calls away from a different business.

Data quality: can you prove your margins in one export?

Here’s the adjustment almost nobody prepares for: can you produce job-level margins for the last three years in one export?

Not “revenue by month from QuickBooks.” Job by job: what you quoted, what labor and materials actually cost, what you made. Buyers pay for what the records prove. If your job costing lives in a scheduler’s head or across three disconnected apps, every claim you make in negotiation gets a haircut for uncertainty, and diligence drags for months.

This is where we have skin in the game: we build custom software and reporting layers for home-services operators, and the sale-readiness gap is the same gap that hurts them day to day. A custom reporting layer over your existing field-service software that consolidates job-level cost data isn’t just an operations upgrade; 18 months of clean exports is diligence ammunition.

Tech stack: do you own your systems or rent them?

The last adjustment is the one the free calculators will never mention.

A rented per-seat stack is a cost the buyer inherits and a dependency they can’t control. One prospect showed us a $57,000-per-year software quote at 14 techs; a buyer underwriting that deal adds every year of that bill to their cost model, and if the platform gates API access or data export behind a higher tier, your own job history is partly locked inside someone else’s product. That’s a diligence liability: the data that proves your margins isn’t fully yours to hand over.

An owned system is the opposite: it’s an asset that transfers. Custom scheduling, quoting, or reporting software conveys with the sale like a truck or a customer list, with no per-seat meter running and no export ceiling. We’ve watched “the software comes with the business, here’s the repo and the data” land in a data room as a genuine differentiator, because almost no seller at this size can say it.

The worked example, start to finish

A coatings and install company. Round numbers.

Step 1, SDE. Tax-return net profit is $180,000. Add back the owner’s $110,000 salary, $20,000 of documented personal expenses and one-time costs, and $30,000 of interest and depreciation.

SDE = $340,000.

Step 2, multiple. At $340,000 SDE with the owner managing rather than on the truck, the broker-published range is 2.2x to 3.0x. Before adjustments that’s $748,000 to $1,020,000.

Step 3, adjustments.

The sales dependency keeps it out of the top quartile; the recurring base and clean records keep it well off the bottom. A realistic landing spot is around 2.5x: roughly $850,000, with the clean data doing quiet work the whole negotiation, because nothing the seller claims gets discounted for doubt.

That’s the entire method. Same three steps whether the answer is $350,000 or $3.5 million.

The free calculators, and what they miss

Honest note: you can get a first anchor for free right now. ServiceTitan publishes a free HVAC and service business valuation calculator, and Housecall Pro publishes free valuation calculators for plumbing, HVAC, and field service. ServiceTitan’s uses the classic formula, net income plus depreciation and amortization times an earnings multiplier; Housecall Pro’s takes revenue, cost of sales, overhead, and a multiplier you pick (their guidance: 2 to 5 for home services).

Use them. They’re directionally fine, and they’re free.

What they don’t do is Step 3. No owner-dependency question, no recurring-revenue weighting, no concentration check, no data-quality score. They hand you the middle of the range and stop exactly where the money starts moving. They also, understandably, won’t tell you that the stack you’re renting from them is one of the adjustments.

We’re building a valuation calculator that includes the adjustment layer, on this page, structured exactly like the three steps above. Until it ships, the by-hand version you just read is the same math.

If your exit is 12 to 24 months out

The multiple table is set by the market. The adjustments are set by you, and every one of them takes a year or more to show up in the records a buyer will read.

The two that owners can’t fix with management changes alone are the last two: proving margins and owning the stack. If your job-level history is scattered across per-seat apps you can’t fully export, that’s a build project, and it’s the kind we do for home-services operators: consolidate the data, own the system, and walk into diligence with an asset instead of a liability. If a sale is even on your five-year horizon, the earlier that starts, the more of it shows up in the price.

For the rest of the exit process, the broker conversation, the earnout traps, the timeline, start with selling your home-services business.
