“How much is my business worth?”
It’s the first question every owner asks, and it’s also the question with the most bad answers floating around. A free business valuation calculator spits out a number in thirty seconds. Your CPA gives you a different number. A friend who sold his company swears businesses “go for one times revenue.” Then a private equity firm sends you a flattering letter implying a price they have no intention of actually paying.
The honest answer is that your business is worth what a qualified buyer will pay for it in a competitive process. That sounds unhelpful, but you can actually estimate that number with real accuracy before you ever go to market. You just have to use the same math buyers use. This guide walks through it step by step.
The Short Answer: Earnings Times a Multiple
For nearly every privately held business, value comes down to one formula:
Business Value = Adjusted Earnings × Market Multiple
Both inputs need explanation.
Adjusted earnings means the true cash-generating power of your business after normalizing for owner-specific and one-time items. Depending on your size, this is either Seller’s Discretionary Earnings (SDE) or Adjusted EBITDA. If you’re not sure which applies to you, we cover that in SDE vs. EBITDA: Which One Applies to Your Business Sale?
The market multiple is a number, usually somewhere between 2x and 10x for private companies, that reflects your industry, size, growth, and risk. Current benchmarks are in our guide to EBITDA Multiples by Industry (2026).
So a business generating $2 million in adjusted EBITDA at a 5x multiple is worth roughly $10 million. The concept is simple. The judgment calls inside each input are where valuations swing by millions of dollars, so let’s take them one at a time.
Step 1: Calculate Your True Earnings
The profit on your tax return is almost never the number a buyer values. Most private businesses are run to minimize taxes, not to showcase profitability, so the first job in any valuation is rebuilding your earnings the way a buyer will see them.
If your business earns under about $1M in profit, use SDE
Seller’s Discretionary Earnings represents the total financial benefit a single owner-operator receives from the business:
SDE = Pre-tax net income + owner’s salary + owner’s benefits and perks + interest + depreciation + amortization + one-time expenses
If your business earns over about $1M in profit, use Adjusted EBITDA
Larger businesses are valued on Adjusted EBITDA, which assumes the buyer will pay a market-rate salary to whoever replaces you:
Adjusted EBITDA = Net income + interest + taxes + depreciation + amortization ± normalizing adjustments (“add-backs”)
Add-backs are where deals are won and lost. Above-market owner pay, personal vehicles, one-time legal fees, family members on payroll who don’t really work there, expenses that won’t recur. Documenting these properly can add hundreds of thousands of dollars to your earnings base, and that base gets multiplied 4, 5, or 6 times in the final price. We break this down fully in What Is Adjusted EBITDA? Add-Backs Explained.
Quick example. A distribution company shows $1.4M in net income. After adding back $250K in excess owner salary, $80K in one-time litigation costs, and $70K in personal expenses run through the business, Adjusted EBITDA comes to $1.8M. At a 5x multiple, those add-backs alone added $2 million to the valuation.
Step 2: Apply the Right Multiple
Multiples aren’t assigned by a formula. They’re set by what real buyers are paying for companies like yours right now, and three things drive them.
Industry. Every industry has a customary trading range. Recurring-revenue businesses like software, route-based services, and healthcare command premium multiples. Project-based and cyclical businesses like construction and e-commerce trade lower. Most lower-middle-market businesses land somewhere between 3x and 8x EBITDA.
Size. This one surprises a lot of owners: bigger businesses get bigger multiples for the same dollar of profit. A company with $5M in EBITDA will trade at a meaningfully higher multiple than an identical business earning $1M, because larger earnings attract more buyers. Private equity firms, strategic acquirers, and family offices all show up, and more competition means higher prices. Crossing $1M, $3M, and $5M in EBITDA each tends to add a full turn or more to the multiple.
Quality and risk. Within your industry’s range, the specifics of your company determine whether you land at the bottom, middle, or top. Recurring revenue and long-term contracts push you up. Customer concentration pulls you down, especially once any single customer passes 15 to 20% of revenue. Buyers also look hard at growth trajectory, the cleanliness of your financials, and whether there’s real management depth beneath you. Owner dependence is the big one; if the business can’t run without you, buyers discount heavily. We wrote about fixing that in Reducing Owner Dependence.
Step 3: Do the Math (A Worked Example)
Let’s value a hypothetical commercial services company:
| Input | Amount |
|---|---|
| Revenue | $12,000,000 |
| Net income | $1,500,000 |
| Add-backs (excess owner comp, one-time items) | $400,000 |
| Adjusted EBITDA | $1,900,000 |
| Industry multiple range | 4.0x to 6.0x |
| Company-specific multiple (60% recurring revenue, low concentration, strong GM in place) | 5.5x |
| Estimated enterprise value | ~$10,450,000 |
One caution on that final number: it’s enterprise value, the headline price. What you actually walk away with depends on working capital targets, debt payoff, deal structure, and taxes.

What About Online Business Valuation Calculators?
A business valuation calculator is a fine starting point. It forces you to gather your earnings figures and it shows you how the earnings-times-multiple math works. Use one to get a directional range.
Just understand what a calculator can’t do. It can’t verify or maximize your add-backs, which are often the single biggest value lever. It can’t assess customer concentration, owner dependence, or the quality of your revenue. It doesn’t know whether your business will attract individual buyers, strategics, or private equity, and that answer changes the multiple materially. And it certainly can’t create the competitive tension among buyers that produces top-of-range outcomes.
Think of a calculator as a thermometer, not a diagnosis. For a number you can actually plan your exit around, you need a valuation built from your specific financials and current buyer demand in your industry.

Valuation Myths That Cost Owners Money
“Businesses sell for a percentage of revenue.” Only a handful of industries, like some agencies and some SaaS companies, are truly revenue-valued. For everyone else, revenue multiples are just shorthand for earnings multiples. A 10% margin business and a 25% margin business with identical revenue have very different values.
“My business is worth what I need for retirement.” Buyers don’t price your goals. They price your cash flow and your risk. Start with the market number, then plan backward from there.
“The unsolicited offer I received tells me my market value.” A direct approach from a single buyer routinely comes in 15 to 30% below what a competitive process produces. One buyer is not a market.
“I’ll build value right before I sell.” Most of the things that move your multiple, like recurring revenue, management depth, clean financials, and customer diversification, take 12 to 24 months to build. If a sale is even on your radar, start now. See Preparing to Sell Your Business.
How to Get an Accurate Valuation
Pull together three years of financials plus a trailing-twelve-month P&L. Draft your add-back schedule, listing every owner benefit, one-time cost, and non-recurring item along with documentation for each. Benchmark against real private-market multiples for your industry and size rather than public-company data, which runs far higher than what private businesses actually sell for. Then get a professional opinion of value from an advisor who sees actual closed transactions in your revenue range.
Frequently Asked Questions
How much is a business worth that makes $1 million a year in profit? Usually somewhere between $3 million and $6 million, depending on the industry, the quality of the revenue, and how much of that $1M survives buyer scrutiny as adjusted EBITDA or SDE. Recurring-revenue businesses land at the high end or above it. Owner-dependent or project-based businesses land lower.
What is the rule of thumb for valuing a business? The most common rule of thumb is 2 to 3.5x SDE for small owner-operated businesses and 4 to 8x adjusted EBITDA for lower-middle-market companies. Treat rules of thumb as starting points only, because the spread within any industry is enormous.
How do buyers value a business? Buyers mainly use the market approach: adjusted earnings times a multiple benchmarked against comparable transactions. Sophisticated buyers cross-check with a discounted cash flow analysis, and for asset-heavy businesses they’ll also look at an asset-based floor value.
Is a business valuation the same as the price I’ll receive? No. A valuation is the starting estimate. Price is negotiated, and deal structure, working capital adjustments, earnouts, and competition among buyers all move the final number. That’s why the sale process matters as much as the valuation itself.
How much does a business valuation cost? Formal certified appraisals for litigation, ESOPs, or estate purposes run $5,000 to $25,000 or more. For sale planning, most M&A advisors, including Venture Exits, provide a confidential market-based opinion of value at no cost.
