If you’re thinking about selling your business, the first question you need to answer is: what is it actually worth?
Most business owners are surprised — sometimes pleasantly, often not — when they find out. Some have been running profitable businesses for years and assume they’ll walk away with a number that funds a comfortable retirement. Others discover their business is worth far less than expected because of factors they never considered.
Getting an accurate business valuation before you sell isn’t just about knowing your number. It’s about having time to improve it.
This guide walks you through the most common business valuation methods, what drives value up or down, and the tools you can use to get a reliable estimate — without paying thousands for a formal appraisal right away.
Why Business Valuation Matters Before You Sell
Most business owners only think seriously about valuation when they’re ready to sell. That’s a mistake.
Here’s why: the factors that drive business value — like reducing owner dependence, diversifying your customer base, documenting your processes, and building a strong management team — take time to fix. If you only discover your business’s weak spots when a buyer’s due diligence team is already in your financials, it’s too late to do anything about them.
Business owners who get valued 2–3 years before their intended exit consistently achieve better outcomes than those who wait. They have time to address weaknesses, increase value, and approach the sale from a position of strength rather than urgency.
The 4 Most Common Business Valuation Methods
There’s no single “correct” way to value a small business. Different methods are appropriate for different types of businesses. Here are the four you’re most likely to encounter.
1. EBITDA Multiple (Earnings-Based Valuation)
Best for: Established businesses with consistent profitability.
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It’s a measure of a business’s core operating profitability, stripped of financing and accounting decisions.
The EBITDA multiple method values your business by multiplying your EBITDA by an industry-specific multiple. For example:
- Your annual EBITDA: $500,000
- Industry multiple: 4x
- Estimated business value: $2,000,000
The multiple varies significantly by industry, business size, and growth rate. Small businesses typically sell for 2x–5x EBITDA, while larger or faster-growing businesses can command multiples of 6x–10x or higher.
What affects your multiple:
- Revenue growth rate (faster growth = higher multiple)
- Customer concentration (fewer large customers = lower multiple)
- Owner dependence (if the business can’t run without you, lower multiple)
- Recurring vs. one-time revenue (recurring is valued higher)
- Industry (tech and SaaS businesses typically get higher multiples than service businesses)
2. Seller’s Discretionary Earnings (SDE) Multiple
Best for: Small owner-operated businesses with revenue under $5 million.
SDE is similar to EBITDA but adds back the owner’s salary, benefits, and personal expenses that run through the business. It represents the total financial benefit a full-time owner-operator would receive from the business.
For small businesses, buyers often pay 2x–3.5x SDE. So if your SDE is $300,000, your business might be valued at $600,000–$1,050,000.
SDE is the most common valuation method for businesses sold on platforms like BizBuySell, where most listings are small owner-operated companies.
3. Revenue Multiple
Best for: High-growth businesses or businesses with low current profitability.
Some businesses — particularly SaaS companies, agencies, and businesses with strong recurring revenue — are valued as a multiple of annual revenue rather than earnings. This is common when a business is growing quickly but reinvesting profits into growth.
Revenue multiples for small businesses typically range from 0.5x–2x annual revenue, though SaaS businesses with high retention can command 3x–5x or more.
4. Asset-Based Valuation
Best for: Businesses with significant physical assets, or businesses that are being wound down.
Asset-based valuation adds up the fair market value of your business’s assets (equipment, inventory, property, accounts receivable) and subtracts liabilities. It’s rarely the primary method for going-concern businesses, but it establishes a floor — what the business would be worth if you simply liquidated everything.
What Reduces Your Business’s Value
Understanding what drives your valuation down is just as important as knowing the methods. Here are the most common value killers:
Owner dependence. If all the key relationships, knowledge, or decisions sit with you personally, buyers see high transition risk. They’ll either pay less or walk away. The most valuable businesses can run and grow without the owner’s daily involvement.
Customer concentration. If one customer represents more than 15–20% of your revenue, that’s a red flag for buyers. Losing that customer post-sale could devastate the business. Diversifying your customer base before selling directly improves your valuation.
Undocumented processes. If your operations exist only in your head, a buyer has no way to verify they can be replicated. Businesses with documented SOPs, employee handbooks, and clear operational systems sell faster and at higher prices.
Declining revenue trends. A business showing three years of revenue growth is worth significantly more than one with flat or declining revenue, even if the current EBITDA numbers look similar.
Weak financials or poor record-keeping. Buyers will scrutinize your books. Messy financials, personal expenses mixed with business expenses, or inconsistent record-keeping will either kill a deal or force a price reduction.
Key person dependencies beyond the owner. If a key employee — a top salesperson, a technical specialist, a long-time operations manager — left tomorrow and it would damage the business, that’s a risk buyers will price in.
What Increases Your Business’s Value
The flip side of the list above: here’s what you can do over the next 1–3 years to meaningfully increase what your business is worth.
Reduce owner dependence. Hire or develop a management layer that can run day-to-day operations. Document your knowledge. Build systems. This is the single highest-ROI improvement most small business owners can make.
Diversify revenue. Add customers, add revenue streams, convert one-time clients to retainer relationships. The goal is no single customer over 10–15% of revenue.
Clean up your financials. Work with an accountant to separate personal and business expenses, normalize your financials, and present three years of clean books.
Build recurring revenue. Subscription contracts, retainer agreements, maintenance contracts, and annual service agreements all increase value because they provide revenue predictability that buyers pay a premium for.
Document your processes. Create SOPs for every key function. Use tools like Notion, Google Drive, or Trainual to build an operational knowledge base that transfers with the business.
Grow revenue consistently. Even modest consistent growth signals business health. Flat revenue for three years followed by a spike in year four looks less credible than steady growth.
Tools to Value Your Business
You have several options for getting a business valuation, ranging from free online estimates to full formal appraisals.
Online Valuation Tools
BizEquity is one of the most widely used online business valuation platforms. It uses a proprietary algorithm based on over one million business valuations to generate an instant estimate of your business’s value. You input your financial data, and BizEquity returns a valuation along with benchmarks showing how your business compares to peers in your industry.
BizEquity is a good starting point if you want a quick, data-driven estimate without engaging a formal appraiser.
Value Builder System takes a different approach. Rather than purely financial valuation, it assesses your business across eight drivers of value — including owner dependence, customer diversification, and growth potential — and gives you a Value Builder Score from 0–100. The score tells you how attractive your business would be to a buyer, not just what it’s worth today.
What makes Value Builder particularly useful for exit planning is that it identifies your specific weaknesses and shows you exactly what to work on. Businesses that score above 80 on the Value Builder assessment sell for significantly higher multiples than those that score below 50.
Business Brokers
A business broker can provide a Broker’s Opinion of Value (BOV) — typically at no charge if they’re hoping to list your business. The BOV gives you a realistic estimate of what your business would sell for in the current market, based on comparable transactions.
The limitation: brokers are motivated to list businesses, so they may provide optimistic valuations. Getting opinions from two or three brokers gives you a more realistic range.
Certified Business Appraisers
For businesses where accuracy matters — estate planning, legal disputes, SBA loans, or complex transactions — a formal appraisal from a Certified Business Appraiser (CBA) or Accredited Senior Appraiser (ASA) is the gold standard. These typically cost $3,000–$10,000 depending on business complexity.
For most small business owners doing preliminary exit planning, a formal appraisal isn’t necessary at first. Start with an online tool or broker opinion, then commission a formal appraisal when you’re within 12–18 months of an actual sale.
How to Increase Your Valuation Before Selling: A Simple Framework
If you’re 2–5 years from your intended exit, here’s a straightforward framework:
Year 1: Assess and identify gaps. Get a Value Builder assessment to understand where you stand. Identify your three biggest value drivers and your three biggest weaknesses. Use BizEquity or a broker’s opinion to get a baseline valuation number.
Year 2: Fix the fundamentals. Focus on the highest-impact improvements: reducing owner dependence, cleaning up financials, documenting key processes, and improving customer diversification. Track your progress through quarterly reviews.
Year 3 (or 12–18 months before sale): Prepare for market. Commission a formal appraisal. Engage a business broker or M&A advisor. Begin the confidential marketing process.
How Much Is Your Business Worth? A Quick Estimate
If you want a rough estimate right now, here’s a simple calculation:
- Calculate your annual SDE (net profit + owner’s salary + owner’s benefits + any personal expenses run through the business)
- Find the typical SDE multiple for your industry (typically 2x–3.5x for small businesses)
- Multiply
Example:
- Net profit: $150,000
- Owner’s salary: $100,000
- Owner benefits and perks: $30,000
- SDE: $280,000
- Multiple: 2.5x
- Estimated value: $700,000
This is a rough estimate, not a formal valuation. But it gives you a starting point for planning.
The Bottom Line
Valuing your business before you’re ready to sell isn’t pessimistic — it’s strategic. The number you get today isn’t your destiny; it’s your starting point.
Most business owners who engage seriously with their exit planning 2–3 years before selling discover they can meaningfully increase their valuation by addressing specific, fixable problems. The ones who wait until they’re ready to sell take whatever the market gives them.
Start with a Value Builder assessment or a BizEquity valuation to understand where you stand. Then build a plan to improve what you find.
