What is a company valuation?

A company valuation is the process of determining the economic worth of a business at a specific point in time. It uses financial data, market conditions, and projections to arrive at a dollar figure that represents what your business is worth.

You might need a valuation for a range of reasons, including:

• Financial reporting and tax compliance
• Seeking business loans or lines of credit
• Negotiating a sale or acquisition
• Succession planning and ownership transitions
• Bringing in new partners or investors
• Resolving legal disputes like divorce or shareholder disagreements

Understanding your company's value puts you in a stronger position for any of these situations.

Why you need to know your business value

Knowing what your business is worth isn't just useful when you're ready to sell. A current valuation helps you make better decisions across many scenarios.

If you're preparing to sell, a valuation gives you a defensible asking price and strengthens your negotiating position. Learn more about the full process in this guide on how to sell your business.

If you're seeking financing, lenders and investors want to see what your business is worth before committing capital. A solid valuation builds confidence in your application.

If you're bringing in partners, valuation determines what a fair ownership stake looks like. It protects both you and the incoming partner from disputes down the road.

If you're planning your estate, business value directly impacts tax obligations and inheritance decisions. Accurate numbers help avoid surprises for your family.

If you're involved in legal proceedings, courts require formal valuations in divorce settlements, partnership disputes, and other litigation.

Even if none of these apply right now, running a valuation as a regular health check helps you track growth and spot areas that need attention. It's a useful part of any small business exit strategy.

Preparing for a business valuation

A credible valuation starts with organized, accurate financial records. Before you begin any calculation, gather the key documents that support your numbers.

You'll need these core financial statements covering at least the past three years:

• Profit and loss statements showing revenue, expenses, and net income trends
• Balance sheets listing all assets, liabilities, and equity
• Cash flow statements tracking how money moves through your business
• Federal and state tax returns to verify reported income

Beyond your financial statements, gather supporting information that adds context to the numbers:

• A detailed list of all tangible and intangible assets
• Customer concentration data showing how revenue is spread across clients
• Industry benchmarks for businesses of your size and type
• A full accounting of debts, leases, and ongoing financial obligations

Xero can help you generate up-to-date financial statements and reports, giving you a strong foundation for any valuation method you choose.

How to value a company

There's no single formula that works for every business. The right approach depends on your industry, size, growth stage, and the reason behind the valuation. Here are nine commonly used methods.

Book value calculation

Book value is the simplest way to estimate what your business is worth based on its balance sheet. You subtract what you owe from what you own.

Formula

Book value = Total assets - Total liabilities

Example

If your business has $10 million in total assets and $5 million in debts and other liabilities, the book value is $5 million. This figure represents the accounting value of your ownership stake.

Book value works well as a starting point, particularly for asset-heavy businesses. It doesn't account for earning potential or intangible assets like brand recognition, so it often understates the true market value of a going concern. For a deeper look at this concept, see the Xero guide on net worth.

Liquidation value calculation

Liquidation value estimates what you'd receive if you sold off all your business assets individually and paid off debts. It typically produces a lower number than book value because assets sold under time pressure rarely fetch full market price.

Formula

Liquidation value = Market value of all assets sold individually - Total liabilities

Example

A business with $10 million in book assets might only receive $7 million selling equipment, inventory, and property at auction. After paying $5 million in liabilities, the liquidation value would be $2 million.

This method is most relevant when a business is closing or when a buyer wants to understand the floor price. It's also useful for lenders assessing worst-case collateral value.

Seller's discretionary earnings (SDE)

SDE is the preferred valuation method for small, owner-operated businesses. It calculates the total financial benefit a single owner-operator takes from the business each year.

Formula

SDE = Net income + Owner's salary + Owner's personal expenses run through the business + Non-recurring expenses

Example

Your business reports $500,000 in net income. You also run a $50,000 personal vehicle and $30,000 in personal insurance through the business. Your SDE would be $580,000.

Buyers then apply a multiplier, typically 1x to 4x, depending on the industry and risk profile. SDE is particularly useful for small businesses where the owner's compensation significantly impacts reported profit.

Earnings multiples (EBITDA and net profit)

Earnings multiples are among the most widely used valuation methods for established businesses. You take a measure of earnings and multiply it by a factor that reflects your industry and growth potential.

Formula

Company value = Earnings x Multiplier

There are two common earnings measures to use:

• EBITDA (earnings before interest, taxes, depreciation, and amortization): strips out financing and accounting decisions to show core operating performance. Learn more about depreciation and how it affects your calculations.
• Net profit: the bottom-line figure after all expenses

Multipliers typically range from 2x to 10x, depending on factors like:

• Industry growth rate and stability
• Revenue consistency and recurring income
• Customer diversification
• Strength of your management team
• Competitive advantages or barriers to entry

The IRS valuation guidance recommends considering multiple approaches when assessing business value. Industry-specific multipliers vary widely; a stable accounting practice might command a 5x EBITDA multiple, while a high-growth tech company could justify 10x or higher.

Revenue multiples

Revenue multiples value a business based on its annual sales rather than profits. You multiply total revenue by an industry-appropriate factor.

Formula

Company value = Annual revenue x Multiplier

Example

A SaaS company generating $2 million in annual recurring revenue with a 6x multiplier would be valued at $12 million.

This method is especially useful for high-growth businesses that aren't yet profitable, or for companies where profit margins are temporarily compressed due to investment in growth. Revenue multipliers vary significantly by industry, typically ranging from 0.5x to 10x.

Free cash flow multiples

Free cash flow (FCF) measures the cash a business generates after accounting for capital expenditures. It shows how much cash is actually available to owners and investors.

Formula

Company value = Free cash flow x Multiplier

Example

A manufacturing company with $1.5 million in free cash flow and a 7x multiplier would be valued at $10.5 million.

FCF multiples work well for capital-intensive businesses where significant reinvestment is required. It provides a more realistic picture than earnings multiples for companies with heavy equipment or infrastructure costs.

Entry-cost analysis

Entry-cost analysis estimates what it would take to build an identical business from scratch. It considers every expense you'd face starting from zero, including equipment, hiring, marketing, licensing, and the time needed to reach the same revenue level.

Formula

Entry cost = Sum of all costs to replicate the business (assets + setup + ramp-up period)

Example

A restaurant with established supplier relationships, trained staff, a fitted-out location, and three years of customer goodwill might cost $1.2 million to replicate from the ground up, even if the book value of its physical assets is only $400,000.

This method works best for asset-heavy, replicable businesses. It's less useful for companies where value comes primarily from intellectual property, brand recognition, or unique talent.

Market capitalization

Market capitalization is the standard valuation measure for publicly traded companies. It reflects the market's collective assessment of a company's value at any given moment.

Formula

Market capitalization = Current share price x Total number of shares outstanding

Example

A company with 10 million shares trading at $25 per share has a market capitalization of $250 million.

Market cap is straightforward and updates in real time, but it reflects market sentiment as much as fundamental value. It's only applicable to companies with publicly traded shares.

Enterprise value

Enterprise value (EV) builds on market capitalization to give a more complete picture of what it would actually cost to acquire a company. It accounts for the debt a buyer would assume and the cash they'd receive.

Formula

Enterprise value = Market capitalization + Total debt - Cash and cash equivalents

Example

A company with a $250 million market cap, $50 million in debt, and $20 million in cash has an enterprise value of $280 million.

EV is the preferred metric for acquisitions because it reflects the true cost of buying the entire business. It's more useful than market cap alone when comparing companies with different capital structures.

Choosing the right valuation method for your business

The best valuation method depends on what type of business you run and why you need the valuation. No single approach tells the complete story.

Match your method to your business type:

• Asset-heavy businesses (manufacturing, real estate): book value, liquidation value, or entry-cost analysis
• Service businesses: SDE for small operations, earnings multiples for larger ones
• High-growth companies: revenue multiples or free cash flow multiples
• Mature, profitable businesses: EBITDA multiples or free cash flow multiples
• Publicly traded companies: market capitalization and enterprise value

Match your method to your purpose:

• Selling your business: SDE or earnings multiples, supported by a professional appraisal
• Applying for loans: book value or earnings multiples, depending on the lender's requirements
• Attracting investors: revenue multiples or EBITDA multiples
• Internal planning: any method that helps you track progress year over year

The IRS valuation guidance recommends that valuators consider all three recognized approaches: the income approach, the market approach, and the asset approach. Calculating two or three methods gives you a realistic range rather than a single number.

How to increase your business valuation

Your business value isn't fixed. Specific actions can meaningfully improve what buyers, lenders, and investors see when they look at your numbers.

Improve profitability and margins

Increasing profit margins has a multiplied effect on your valuation. Every additional dollar of profit could add $2 to $10 in business value, depending on your industry multiplier. Focus on reducing unnecessary costs and improving pricing strategies.

Build recurring revenue

Predictable, repeating revenue streams are more valuable than one-time sales. Subscription models, service contracts, and retainer agreements all make your cash flow more reliable and your business more attractive to buyers.

Document processes and reduce owner dependency

A business that runs smoothly without its owner is worth significantly more than one that depends on a single person. Document key processes, train your team, and delegate decision-making so the business can operate independently.

Diversify your customer base

If a single client represents more than 15% of your revenue, buyers see that as a risk. Actively pursue new customers and markets to spread your revenue across a broader base. A diversified customer list strengthens your position in any valuation.

Invest in intellectual property and brand

Patents, trademarks, proprietary technology, and strong brand recognition create value that goes beyond physical assets. These intangible assets can justify higher multipliers and set your business apart from competitors.

Factors that affect your company's value

Several external and internal factors influence what your business is worth. Understanding these helps you focus on what you can control.

Key factors that drive business value include:

• Industry and market conditions: growing industries with favorable trends command higher multiples
• Business performance metrics: consistent revenue growth, healthy margins, and strong cash flow all increase value
• Competitive advantages: patents, exclusive contracts, proprietary technology, and strong brand recognition create a premium
• Financial record quality: clean, well-organized books give buyers confidence and support higher valuations
• Management team strength: a capable team that can operate without the owner reduces buyer risk

Xero gives you the tools to track these value drivers in real time through up-to-date financial reports and dashboards. Accurate, current data is the foundation of a strong valuation.

When to hire a professional valuator

You can handle some valuation scenarios yourself, but others call for expert help. Knowing the difference saves you time and protects your interests.

DIY valuation works well for:

• Internal planning and annual benchmarking
• Rough estimates for preliminary conversations with potential buyers
• Early-stage discussions with lenders or partners

Hire a professional when you're:

• Preparing to sell your business or bring in investors
• Involved in litigation, including divorce or partnership disputes
• Dealing with estate planning and tax compliance
• Managing a business with complex structures, such as multiple entities or significant intangible assets

Look for valuators with recognized certifications:

• Certified business appraiser (CBA)
• Accredited senior appraiser (ASA)
• Accredited in business valuation (ABV)

Expect to invest $5,000 to $10,000 for a small business valuation and $10,000 to $20,000 or more for mid-market companies. The process typically takes four to eight weeks from start to finish. Keep in mind that the IRS can impose penalties for incorrect appraisals used in tax filings, making a qualified professional a worthwhile investment.
