How to Calculate How Much a Business Is Worth
To calculate how much a business is worth, you multiply its earnings or revenue by an industry-specific multiple, or subtract its total liabilities from total assets. Most small businesses use the SDE method: add net profit, owner’s salary, and non-essential expenses, then multiply by 2 to 3.5. The right method depends on your business size, industry, and the purpose of the valuation.
Why You Need a Business Valuation
A business valuation tells you whether your growth strategy is building equity, whether your profit margins are competitive in your industry, and whether your business could survive a sudden ownership change.
Over 80% of small business owners, according to Fit Small Business, do not know the current value of their company. That matters because the business is often the owner’s largest personal asset and primary retirement plan. Getting a valuation done early is one of the most practical financial decisions an owner can make.
5 Methods to Calculate Business Worth
No single formula works for every business. Each method looks at value through a different lens. The right one depends on your industry, your financials, and who you are calculating for.
| Method | What It Measures | Best For | Quick Formula |
| Asset-Based | Net tangible assets | Manufacturing, real estate | Total Assets minus Total Liabilities |
| SDE Multiple | Owner earnings power | Small businesses under $5M | (Net profit + owner’s salary + add-backs) x Multiple |
| EBITDA Multiple | Operating profit | Mid-size businesses over $5M | EBITDA x Industry Multiple |
| Revenue Multiple | Top-line growth | High-growth, early-stage firms | Annual Revenue x Industry Multiple |
| Discounted Cash Flow | Future income potential | SaaS, subscription businesses | Present value of projected future cash flows |
Each method produces a different number. Professional appraisers use two or three of these together to arrive at a range, not a single figure.
SDE vs EBITDA: Which Formula Applies to Your Business?
Seller’s Discretionary Earnings (SDE) is designed for small businesses where the owner is also the operator. It starts with pre-tax net earnings, then adds back the owner’s salary, personal expenses run through the business, one-time costs, and interest, depreciation, and amortization. The idea is to show what the business could earn under a new owner who takes over day-to-day operations.
SDE Formula: Net earnings before taxes + owner’s salary + personal draws + non-essential expenses + interest + depreciation + amortization
EBITDA removes the owner’s compensation from the picture entirely. It is used for larger businesses where professional management is already in place and buyers are typically private equity firms or strategic acquirers. EBITDA is more capital-structure neutral, which makes it the standard metric in mergers and acquisitions.
| Factor | SDE | EBITDA |
| Best for | Businesses under $5M | Businesses over $5M |
| Includes owner’s salary | Yes | No |
| Used by | Individual buyers, brokers | Private equity, M&A deals |
| Typical multiple | 2x to 3.5x | 4x to 7x or higher |
If you own a small service business or retail shop where you are actively working in the business, use SDE. If your company has a management team in place and you step back from daily operations, EBITDA is the more relevant number.
Industry Valuation Multiples: What Buyers Actually Pay
The multiple you apply to your earnings or revenue is where real subjectivity enters. Buyers in fast-growing industries pay higher multiples because future earnings potential outweighs present profitability. Buyers in stable, mature industries apply lower multiples based on risk.
| Industry | Revenue Multiple | Profit Multiple |
| SaaS / Software | 3x to 5x revenue | 6x to 10x EBITDA |
| Technology Startups | 5x to 8x revenue | Varies widely |
| Service Businesses | 1x to 2x revenue | 2x to 3x SDE |
| Retail Businesses | 0.5x to 1.5x revenue | 1.5x to 2.5x SDE |
| Manufacturing | 1x to 2x revenue | 3x to 5x EBITDA |
| E-Commerce | 2x to 4x revenue | 3x to 5x SDE |
One important 2026 context: median SaaS valuation multiples dropped roughly 60% from their 2021 peak. Buyers are more disciplined now. Using boom-era comparables to justify your asking price will not hold up with a sophisticated buyer.
Tangible vs Intangible Assets: The Hidden Value Most Owners Miss
When you use the asset-based approach, you start with tangible assets: equipment, inventory, real estate, vehicles, and cash. Then you subtract total liabilities to get your book value.
But the more valuable piece of many businesses sits entirely off the balance sheet. Intangible assets include goodwill, brand reputation, customer loyalty, proprietary processes, patents, and an established client base. In service and franchise industries, goodwill often represents the majority of the final selling price.
A business with $400,000 in tangible assets but a loyal customer base generating predictable recurring revenue may command a price well above its book value. This is why asset-based valuation almost always undervalues a healthy operating business on its own.
Why Your Valuation Number and Your Selling Price Are Different
This distinction trips up most first-time sellers. Your valuation is a calculated estimate of economic worth based on financial formulas. Your selling price is what a buyer actually agrees to pay, and those two numbers are rarely identical.
A strategic buyer, meaning a competitor or a company in an adjacent industry, might pay a premium above your calculated value because your customer list or technology creates synergies in their business. Competing bids can drive the price higher. The strength of your lease, the transferability of key relationships, and the health of the overall M&A market all influence the final number.
The reverse is also true. If your business is heavily dependent on you personally, with clients who have relationships only with you and processes that only you understand, buyers will apply a discount. That risk gets priced in.
5 Things That Increase Your Business Valuation Before a Sale
You do not have to wait for a buyer to start improving your number. These moves make a measurable difference.
Clean and organize three years of financials. Buyers and lenders want profit and loss statements, balance sheets, and tax returns for at least three years. Disorganized records reduce confidence and lower your multiple.
Reduce owner dependency. A business that runs without the owner commands a higher multiple. Document your processes, build your management team, and show that revenue does not collapse when you step back.
Build recurring revenue. Subscription models, service retainers, and long-term contracts increase your valuation multiple because they demonstrate predictable future cash flow.
Pay off or minimize debt. Outstanding liabilities reduce your net asset value directly. Cleaning up short-term debt before a valuation improves your balance sheet and signals financial discipline.
Protect and document intangible assets. Registered trademarks, proprietary software, customer contracts, and documented supplier relationships all add verifiable value during due diligence.
Final Thoughts
Calculating how much a business is worth is not a one-size-fits-all exercise. The right method depends on your size, your industry, and your goals. For most small business owners, the SDE multiple is the most practical starting point. As you grow, EBITDA becomes the standard measure. Either way, the businesses that command the strongest valuations are the ones that run cleanly, generate predictable cash flow, and do not collapse when the owner steps back.
FAQs
How do you calculate the value of a business?
The most common method for small businesses is multiplying Seller’s Discretionary Earnings (SDE) by an industry multiple of 2 to 3.5. For larger businesses, EBITDA multiplied by an industry-specific multiple is the standard. Asset-heavy businesses use total assets minus total liabilities as a starting baseline.
How much is a business worth with $1 million in sales?
It depends on your profit margins and industry. A service business with $1 million in revenue and 20% net margins might have an SDE of $200,000 to $250,000 after add-backs, which at a 2.5x multiple values the business at $500,000 to $625,000. A SaaS company with the same revenue could be worth 3 to 5 times the top-line figure.
Is a business worth 3 times profit?
For many small businesses, yes. A multiple of 2 to 3 times SDE is a common benchmark for small and medium-sized operations. Businesses with recurring revenue command multiples of 4x or more.
Is a business worth 5 times profit?
Five times profit is typical for well-established businesses with strong recurring revenue, documented processes, low owner dependency, and clean financials. Private equity buyers typically pay 4 to 7 times EBITDA for mid-sized businesses that meet these criteria.
Is there a formula for valuing a company?
Several. The most widely used are: Business Value = SDE x Multiple, Business Value = EBITDA x Multiple, and Book Value = Total Assets minus Total Liabilities. Most professional valuations blend two or three methods.
How much can I sell my business for?
Your selling price depends on your valuation, buyer pool, market conditions, and negotiation. A seller with clean financials, recurring revenue, and reduced owner dependency typically achieves a higher multiple than industry averages.
What is the formula for net worth of a business?
Business net worth equals total assets minus total liabilities. This captures tangible assets like equipment and inventory, but may not fully reflect intangible value like goodwill, brand equity, or customer relationships.
Does recurring revenue increase a business valuation?
Yes, significantly. Buyers pay higher multiples for businesses with predictable monthly or annual recurring revenue because it reduces their risk. A subscription-based or retainer-driven business is almost always valued higher than a comparable transactional one.
Should I use EBITDA or SDE to value my business?
Use SDE if you are a small business owner actively working in your company with revenue under $5 million. Use EBITDA if your business has professional management in place, revenue exceeds $5 million, or you are approaching private equity buyers.
How do I know if a valuation offer is fair?
Compare the offer to your SDE or EBITDA multiplied by industry benchmarks for your sector. Ask what comparable transactions the buyer used. An independent appraiser can provide a second opinion that either validates the offer or gives you grounds to negotiate.
