Free Business Valuation Calculator: What Is Your Business Worth?

The Short Answer: How Our Business Valuation Calculator Works

Our business valuation calculator takes your industry, revenue, earnings, and key business characteristics -- then applies industry-specific multiples from real transaction data to produce a valuation range.

Free, two minutes, no email required. You see what is driving your number up or down.

Why Most Online Valuation Calculators Get It Wrong

Search for "business valuation calculator" and you will find dozens of tools that all work the same way: enter revenue, pick a multiple from a dropdown, hit calculate. The problems are fundamental.

Valuation multiples vary enormously by industry, size, and risk profile. A SaaS business with 90% recurring revenue might trade at 8-12x ARR. A project-based construction company might trade at 2-3x SDE. A calculator that applies "3x revenue" to both is wrong for both.

What Goes Into an Accurate Business Valuation

Any valuation tool is only as good as its inputs. Here are the factors that actually drive what your business sells for:

Industry

The single biggest factor most free calculators ignore. Multiples vary by 3-5x between industries. A landscaping business and a managed IT services company with identical revenue and profit will sell for very different amounts.

Earnings: SDE or EBITDA

Revenue matters, but buyers pay based on earnings -- specifically SDE or EBITDA, depending on your size. SDE is standard for owner-operated businesses under $1M in earnings. EBITDA is standard above $1.5M. Getting this wrong changes your valuation by hundreds of thousands of dollars.

Growth Rate

A business growing at 20% per year commands a higher multiple than one growing at 3%. Buyers are purchasing future cash flows, not just current ones.

Customer Concentration

If one customer accounts for 20%+ of revenue, that is a major risk factor. Lose them and you lose a third of the business. Buyers discount heavily for this.

Owner Dependency

Can this business run without you? If you are the primary salesperson, the key relationship holder, and the only person who knows the processes, that depresses your multiple. Buyers see owner-dependent businesses as riskier bets.

Recurring Revenue

Subscriptions, maintenance contracts, retainers -- anything that auto-renews is worth more than project-based or one-time revenue. A business with 70% recurring revenue will command a higher multiple than an identical business with 10%.

How Our Valuation Calculator Works

The valuation tool works in three steps:

Step 1: Enter your industry and financials. Select your industry, enter annual revenue and earnings (the tool tells you whether to use SDE or EBITDA), and provide your growth rate.

Step 2: Answer a few questions about your business. Customer concentration, owner dependency, recurring revenue percentage, and other factors that actually move multiples.

Step 3: Get your valuation range. You get a range (not a single number) with a clear explanation of what is pushing your valuation higher or lower.

The tool uses industry-specific data and real transaction comparables -- not a generic textbook multiple.

What Your Results Mean

Why You Get a Range, Not a Single Number

No honest valuation gives you a single number. Every business has a range depending on who the buyer is, how the deal is structured, and market conditions at the time of sale.

The low end represents a conservative scenario -- financial buyer, standard terms, no competitive bidding. The high end represents the best case -- strategic buyer, strong market, multiple interested parties.

When a Calculator Estimate Is Enough

A calculator is sufficient when you are:

• Exploring whether selling makes sense -- you need a ballpark, not a precise number
• Planning 2-3 years out -- understanding approximate value helps you set goals
• Comparing improvement strategies -- seeing how reducing concentration or building recurring revenue changes your number
• Having initial conversations with advisors or brokers

When You Need More

If you are actively preparing for a sale within 6-12 months, a calculator is your starting point, not your finish line. Formal valuations account for deal-specific factors -- earnout structures, working capital adjustments, asset vs share sales, buyer synergies -- that no online tool can capture.

5 Ways to Increase Your Valuation Before You Sell

The most useful thing about getting an early estimate is it shows you what to fix. Five changes that consistently move the needle:

1. Reduce Owner Dependency

The single most impactful change for most founder-led businesses. If you are the business, the multiple stays low. Hire a manager, document your processes, and run for 6-12 months with reduced involvement. This alone can shift you from SDE multiples (2-4x) to EBITDA multiples (4-8x).

2. Diversify Your Customer Base

If any single customer represents more than 20% of revenue, fix that before going to market. Buyers will either discount your price or tie the deal to customer retention earnouts -- meaning you bear the risk.

3. Build Recurring Revenue

Convert one-time engagements into subscriptions, retainers, or maintenance contracts wherever possible. Recurring revenue is more predictable and commands higher multiples. Even moving from 10% to 40% recurring can meaningfully change your valuation.

4. Clean Up Your Financials

Separate personal expenses from business expenses. Have at least three years of clean, consistent statements. If your books are messy, hire a bookkeeper now -- it pays for itself many times over at sale.

5. Document Your Processes

Written SOPs, documented systems, trained staff who can execute without you -- these make a business transferable. A business that lives in the owner's head is worth less than one that runs on systems, even if the economics are identical.

When to Get a Professional Valuation

Different tools for different stages:

Use the calculator when:

• You are exploring whether selling is even worth considering
• You want to benchmark your progress over time
• You are planning improvements and want to see projected impact
• You need a quick number for internal discussions

Get a professional valuation when:

• You are actively preparing to sell within 6-12 months
• You are going through a divorce, partnership dissolution, or buyout
• You need a number for estate planning or tax purposes
• A legal proceeding requires a formal business appraisal
• You are raising capital and investors need a defensible valuation

Professional valuations typically cost $5,000 to $20,000 depending on complexity. Use our free valuation tool first to understand your approximate range. If the number makes selling worth exploring, invest in a professional appraisal when you are ready to go to market.

Questions You Might Have

How accurate is a free business valuation calculator?

It gives you a defensible range, not a single precise number. Our calculator uses industry-specific multiples and real transaction data, so the estimate reflects how businesses like yours actually sell. Good enough to start planning around. For an actual sale, you will want a formal valuation from a professional who can account for buyer competition, terms, and earnouts.

What information do I need to use the business valuation calculator?

Annual revenue, earnings (SDE or EBITDA depending on business size), industry, and basic details like growth rate, customer concentration, owner dependency, and recurring revenue percentage. Most owners have this from their financial statements or tax returns.

What is the difference between SDE and EBITDA for valuation?

SDE adds back the owner's total compensation -- standard for owner-operated businesses under $1M in earnings. EBITDA does not add back owner compensation -- standard for larger businesses with professional management. Our calculator handles both. Read our full SDE vs EBITDA comparison for worked examples.

How much is my business worth if I have $1M in revenue?

Revenue alone does not determine value. A $1M revenue business could be worth $500K to $3M+ depending on industry, profit margins, growth rate, and owner dependency. The multiple is applied to earnings (SDE or EBITDA), not revenue. Our business valuation calculator factors in these variables to give you a realistic range.

When should I get a professional valuation instead of using a calculator?

Use a calculator for planning and exploring whether selling makes sense. Get a professional valuation when you are actively preparing to sell, going through a divorce or buyout, doing estate planning, or need a number for a legal or tax context. Professional appraisals typically cost $5,000 to $20,000.
