Ask ten business owners what their company is worth and most will reach for a rule of thumb they heard at a trade show or read online. "HVAC companies sell for one times revenue." "Restaurants go for 30 cents on the dollar." These shortcuts feel reassuring, but they're the wrong tool for the most important number in your financial life. Here's how valuation multiples actually work, what realistic ranges look like across common Pennsylvania industries, and what separates a business at the top of its range from one at the bottom.

What a multiple actually measures

When brokers and buyers talk about "multiples" for Main Street businesses, they almost always mean a multiple of SDE - Seller's Discretionary Earnings. SDE is the total financial benefit a single owner-operator gets from the business in a year. It starts with your net profit, then adds back your own salary, the interest and depreciation on your tax return, and the personal expenses that run through the company but aren't truly needed to operate it.

Think of SDE as the answer to a simple question: if you were a new owner working in this business full time, how much money would it put in your pocket before financing and taxes? A business with $1.2 million in revenue might have $250,000 in SDE. If similar businesses sell for 3 times SDE, that points to a value around $750,000.

The multiple exists because buyers aren't just paying for last year's earnings - they're paying for the reasonable expectation that those earnings continue. A higher multiple means the market believes the earnings are more durable, more transferable, and less dependent on you personally.

Illustrative ranges by industry

The ranges below are broad, real-world SDE multiples we see for healthy small-to-midsize businesses in Pennsylvania, Maryland, and Delaware. Read them as starting points for a conversation, not appraisals. Your actual number depends on your books, your customer base, your equipment, your lease, and a dozen other specifics no article can see. Larger, well-run businesses often push toward or above the top of these ranges; owner-dependent or thin-margin businesses fall below them.

HVAC & mechanical

Roughly 2.5x to 4.0x SDE. Recurring maintenance agreements are the single biggest lever - a book of service contracts that renews every year turns one-time jobs into predictable revenue and pushes a company toward the top. Heavy reliance on new-construction bids, by contrast, makes earnings lumpy and pulls the multiple down.

Plumbing & electrical

Roughly 2.0x to 3.5x SDE. Licensed trades with a stable base of repeat residential and light-commercial work sell well. What holds them back is usually key-person risk - if the owner is the master license holder and the primary technician, a buyer sees a business that walks out the door with you.

Landscaping & lawn care

Roughly 1.5x to 3.0x SDE. Recurring maintenance routes and commercial contracts earn the higher end; seasonal, one-off installation work earns the lower end. Snow removal and year-round service agreements smooth out the seasonality that otherwise scares buyers.

Restaurants & food service

Roughly 1.5x to 3.0x SDE, with a very wide spread. Independent restaurants are high-effort, thin-margin, and often tied to a specific owner's presence, which keeps multiples modest. A strong lease, a proven concept, clean books, and a location that isn't dependent on the founder standing at the door are what move one toward the top.

Machine shops & precision manufacturing

Roughly 3.0x to 4.5x SDE. Specialized equipment, skilled staff who stay through a sale, and a diversified customer base support strong values. The classic drag is customer concentration - if one account is 40 percent of sales, buyers discount heavily for the risk of losing it.

Distribution & wholesale

Roughly 2.5x to 4.0x SDE. Sticky customer relationships, exclusive product lines or territories, and disciplined inventory management earn the premium. Watch inventory closely: buyers scrutinize whether it's fresh and sellable or slow-moving and overstated on the balance sheet.

Retail

Roughly 1.5x to 3.0x SDE, plus the value of sellable inventory. Location, lease terms, and margins drive the number. Independent brick-and-mortar retail sits lower because of online competition and thin margins; a niche store with loyal customers and a defensible position does better.

Professional & business services

Roughly 2.5x to 4.5x SDE. Accounting, insurance, engineering, and similar firms with recurring clients and contracts command the higher end. The limiter is again personal relationships - if clients hire you rather than your firm, a buyer worries they'll leave when you do, and the multiple reflects that doubt.

Two businesses in the same industry with the same earnings can be worth wildly different amounts. The multiple isn't handed down from the industry - it's earned by how transferable, diversified, and predictable your specific business is.

A principle every experienced business broker will tell you

What moves you to the top of your range

Within any industry band, the same handful of factors decide whether a buyer pays the high multiple or the low one. These are the levers you can actually pull in the years before a sale:

  • Recurring revenue. Service contracts, maintenance agreements, and repeat customers are worth more than one-off project work because a buyer can count on them.
  • Clean, provable books. If your SDE add-backs are documented and your financials reconcile to your tax returns, buyers trust the number and pay for it. Messy records invite discounts.
  • Low owner dependence. A business that runs on trained staff, documented processes, and manager coverage is far more valuable than one where you are the product.
  • Customer diversity. No single customer should make or break the company. Broad, loyal customer bases earn premiums; heavy concentration earns discounts.
  • A trained team that stays. Skilled employees and managers who will remain through and after a sale reduce a buyer's risk - and raise your price.
  • Growth and healthy margins. Steady growth and margins at or above your industry norm signal a business that's well run, not just busy.

What pulls you toward the bottom

The drags are the mirror image, and they show up again and again in real deals: heavy dependence on the owner, one or two customers carrying most of the revenue, declining or erratic sales, commingled personal and business expenses that muddy the earnings, aging equipment that a buyer will have to replace, and a short or unfavorable lease. Any one of these can knock a full point or more off your multiple. Several together can make a business hard to sell at any price.

Use the ranges as a compass, not a map

These industry multiples are genuinely useful for one thing: giving you a rough sense of the neighborhood your business sits in, and showing you which levers raise the number. They are not a substitute for a professional valuation that examines your actual financials, normalizes your earnings, and weighs the specific strengths and risks a buyer will see.

If you're within a few years of selling - or just want to know where you stand - the most valuable step is a real, confidential valuation grounded in your numbers rather than an industry average. It tells you not only what your business is worth today, but which of the levers above would move it most before you go to market.
