- Small service businesses sell for a multiple of earnings. Under about $2 million the earnings used are SDE; above it, EBITDA.
- In the IBBA Market Pulse survey, median multiples for Main Street deals ran from 2.0× to 3.1× SDE between Q2 2023 and Q2 2026.
- Recurring revenue, a business that runs without the owner, and a long record are what move a business toward the top of its range.
How a small service business is valued
Most small service businesses are bought for what they earn. A buyer looks at how much cash the business throws off in a year, then pays a multiple of it. The multiple reflects how sure the buyer is that the earnings will keep coming after you leave.
There are other ways to value a business. An asset value adds up the trucks, tools and inventory. A revenue multiple divides price by sales. For a profitable service business, both are rough. Two companies with the same sales can earn very different amounts, and the trucks are worth the same whichever one owns them. Earnings multiples are what brokers and buyers lean on.
This calculator does three things:
- Works out your earnings two ways, SDE and EBITDA, from numbers on your profit and loss statement.
- Picks the multiple that sale data shows for a business of your size.
- Gives a range, with a point inside it based on the factors that buyers price in.
SDE vs EBITDA: which earnings number a buyer uses
SDE, seller's discretionary earnings, is everything one working owner gets out of the business in a year. Start with net profit on the books, then add back:
- The owner's salary or draw, and the payroll taxes and benefits on it
- Interest on business loans, and depreciation and amortization
- One-off costs that will not repeat, like a lawsuit or a move
- Personal costs run through the business, like a family phone plan or a personal vehicle
EBITDA, earnings before interest, taxes, depreciation and amortization, is close to SDE with one big change: it assumes someone is paid a market salary to do the owner's job. EBITDA = SDE − the cost of a manager.
Smaller businesses are usually bought by someone who will work in them, so SDE is the number that matters. Larger businesses are bought by groups or companies that will hire a manager, so they price on EBITDA.
The calculator's starting numbers show both:
| Line | Math | Amount |
|---|---|---|
| Sales | $1,200,000 | |
| Gross profit | $1,200,000 − $640,000 job costs | $560,000 |
| Net profit on the books | $560,000 − $430,000 overhead | $130,000 |
| SDE | $130,000 + $110,000 owner pay + $30,000 add-backs | $270,000 |
| EBITDA | $270,000 − $85,000 manager | $185,000 |
Which earnings to use is not your choice alone. The calculator picks by size, the way the survey does: if SDE times the small business multiple would put the price over $2 million, it switches to EBITDA. A business near that line can see a jump in value from one band to the next. Treat the edge of a band as a range, not a cliff.
Valuation multiples for small businesses
The International Business Brokers Association and M&A Source run a quarterly survey of business brokers and M&A advisors called Market Pulse. It reports the median multiple paid in deals each quarter, split by deal size. Deals under $2 million are measured against SDE. Deals of $2 million and up are measured against EBITDA.
| Deal size (price) | Priced on | Q2 2023 | Q2 2024 | Q2 2025 | Q2 2026 |
|---|---|---|---|---|---|
| Under $500K | SDE | 2.0× | 2.0× | 2.3× | 2.0× |
| $500K to $1M | SDE | 2.8× | 2.8× | 2.8× | 2.8× |
| $1M to $2M | SDE | 3.0× | 2.8× | 3.0× | 3.1× |
| $2M to $5M | EBITDA | 4.5× | 3.5× | 3.9× | 4.0× |
| $5M to $50M | EBITDA | 4.8× | 5.3× | 5.5× | 5.8× |
Two things stand out. Multiples rise with size: a bigger business is less risky to a buyer and draws more of them. And the medians move from year to year, by a few tenths for small deals and by more for larger ones.
The calculator uses those numbers this way:
- Size band. It checks which band your business lands in by multiplying your earnings by each band's Q2 2026 median, smallest band first.
- Range. For SDE deals the range is the lowest and highest median in the survey from 2023 to 2026, 2.0× to 3.1×. For EBITDA deals it is 3.5× to 5.8×.
- Point. Your factors place you inside that range. A middle score sits on your band's Q2 2026 median.
With the starting numbers, $270,000 of SDE at 2.0× would be $540,000, which is over the $500K top of the smallest band, so the business lands in the $500K to $1M band at 2.8×. The range is $540,000 to $837,000.
The survey also shows how deals were paid for. In Q2 2026, cash at close made up 88% to 92% of the price in the three Main Street bands, and seller financing 6% to 11%. Expect a buyer to ask you to carry some of the price.
What moves a business up or down its range
Brokers and buyers name the same handful of things again and again. The calculator weighs three of them to place you in the range. The weights are our own reading, set out here so you can judge them.
| Factor | Weight | Bottom of range | Top of range |
|---|---|---|---|
| Share of sales from plans and repeat contracts | 40 | 0% | 60% or more |
| Owner dependence | 35 | Mostly stops without you | Runs as normal without you |
| Years in business | 25 | Under 3 | Over 10 |
A score of 50 out of 100 lands on the median for your band. 0 lands on the bottom of the range, 100 on the top. The starting numbers (20% recurring, slows down without you, 3 to 10 years) score 43, which puts the multiple at 2.69× and the point estimate at $726,300.
Other things move value that the calculator does not score:
- Customer concentration. One builder or property manager making up a big share of sales is a risk.
- Trend. Rising sales and margins over three years are worth more than one good year.
- Clean books. Accrual-basis statements that match the tax returns make buyers and lenders comfortable.
- Staff. Licensed techs who will stay, and a manager or lead who can run the schedule.
- Equipment and vehicles. Usually included in the price of a small deal, so their condition matters.
None of these work overnight. A buyer looks at the last three years, so a business that added maintenance agreements last month does not get credit for them yet. Changes that show up over two or three years of statements count for the most.
What a buyer will ask to see
When a buyer or their lender looks at your business, they ask for the same set of papers. Having them ready shortens the sale and supports your numbers.
| Document | Why they want it |
|---|---|
| Three years of profit and loss statements and tax returns | To see the trend and check that the books match what was filed |
| A list of add-backs with proof | To confirm SDE |
| Sales by customer and by kind of work | To check customer concentration and the service and install mix |
| Maintenance and service agreements | To count recurring revenue and check that the agreements can transfer |
| Equipment and vehicle list | To see what is included and what will need replacing |
| Staff list with roles, pay and licences | To see who runs the work and who holds the licences |
| Lease, insurance and licences | To check the business can keep operating after the sale |
A buyer who gets clean answers fast tends to trust the numbers, and a buyer who has to dig tends to lower the offer. Put the folder together a year or two before you plan to sell.
How to raise what your business is worth
Value is earnings times a multiple, so there are two levers.
Raise earnings. Every $10,000 of extra SDE at 2.8× adds $28,000 of value. Price jobs for the margin you need (the profit margin calculator helps), charge a rate that covers every hour (the labor rate calculator), and cut overhead that does not earn its keep.
Raise the multiple. Move sales toward recurring work with maintenance plans and service agreements. Write down how the business runs so it does not live in your head. Put a lead tech or office manager in charge of the schedule. Keep two or three years of clean books.
Start early. Buyers look at the last three years, so changes made the year before a sale count for little. Run the calculator once a year with your real numbers and watch the trend.
Koira's reporting shows sales, job costs and plan revenue in one place, which is what a buyer will ask for. See pricing.
Keep the earnings and the multiple in view together. A cost cut that makes the business depend more on you can raise SDE and lower the multiple at the same time.
