What Is My Online Business Worth? (2026 Valuation Guide for SaaS, Ecommerce & Agencies)

The number most founders name when I ask what their business is worth is usually wrong.

Not because they're bad at math. Because they're using the wrong inputs. They heard "four times revenue" on a podcast. They saw a marketplace listing at "eight times SDE." They talked to a friend who sold for "a lot." None of that is a valuation. That's noise.

I've valued and closed over 75 transactions totaling more than $123M. I've seen what drives prices up and what kills them. I've watched founders leave $1M to $3M on the table by misunderstanding their own number. I've watched other founders sell fast and smart by understanding exactly what the market would pay and why.

Here's how to really think about what your online business is worth.

Why Most Business Valuations Are Wrong

There are three ways business valuations go wrong.

Too high and unapproachable. A founder hears "SaaS sells for 6x ARR" at a conference, does the mental math on their $500K ARR, assumes they should get $3M, and turns down three serious offers between $1.8M and $2.2M while waiting for someone to hit their number. The business never sells. The window closes. Revenue eventually softens. Now the real price is $900K.

Too low and surrendered. A founder thinks their ecommerce brand is worth "maybe a million," gets an LOI at $950K from the first buyer they talk to, and signs. That brand was worth $1.6M with two more buyers at the table. I've seen this exact scenario more times than I can count.

Methodologically correct but competitively wrong. A founder gets a real appraisal from a qualified accountant that says $2.7M based on 3.2x EBITDA. That number is accurate by the formula. But the formula doesn't account for what happens when you have 97 buyers in a competitive process. The same business might trade at $3.6M when buyers are competing against each other. The formula gives you a floor. Competition builds the ceiling.

The real valuation of your business is what a qualified buyer will pay in a real market. Everything else is a directional estimate.

The 27 Factors That Determine Value

I tell every client there are 27 factors that go into valuing a business properly. Here's how to think about them, grouped into four categories:

Financial Metrics (the foundation):

• Revenue size and consistency
• Profit margin relative to industry benchmarks
• Revenue trend (growing, flat, or declining)
• Recurring or subscription revenue percentage
• Quality of earnings (accrual vs. cash, addback defensibility)

Business Quality (the multiple driver):

• Customer retention and repeat purchase rate
• Net revenue retention for SaaS
• Customer acquisition cost stability
• Customer concentration (no single customer above 15% to 20%)
• Revenue channel diversification
• Brand reputation and social proof
• Defensible competitive position

Operational Factors (the risk multiplier):

• Owner dependency and key-person risk
• Team structure and management depth
• SOPs and process documentation
• Technical infrastructure quality (for digital businesses)
• Transferability to a new owner
• Transition complexity

Market Factors (the context):

• Buyer demand for your business type
• Financing availability (what SBA lenders will approve)
• Industry trends in your vertical
• Comparable transaction data
• Geographic flexibility (remote-operable earns a premium)
• Timing and market conditions
• Legal and IP cleanliness
• Tax structure and entity setup

Each factor is not weighted equally. The factors that carry the most weight in most deals: customer concentration, owner dependency, revenue trend, and financial cleanliness. Get those four right and the rest becomes a matter of degree.

Valuation by Business Type

SaaS

SaaS businesses are valued primarily on ARR multiples in 2026, though SDE multiples apply at smaller sizes.

Baseline range: 3x to 5x ARR for SMB SaaS with solid fundamentals. Premium businesses with 110%+ NRR and strong growth trade at 5x to 8x ARR.

What moves the SaaS multiple up:

• Net revenue retention above 105% (customers are expanding, not just staying)
• Annual contracts rather than month-to-month
• Monthly churn below 2%
• Growth rate above 20% year over year
• Founder not in every customer relationship
• Clean, documented codebase

What compresses it:

• Monthly churn above 5%
• Founder is primary salesperson or sole account manager
• One or two customers over 25% of MRR
• Revenue flat or declining for 12+ months

The SaaS businesses I've sold at the high end of their range had one thing in common: the product worked well enough that customers were expanding their usage without the founder selling them on it. That NRR number tells the whole story.

Ecommerce

Ecommerce brands are valued on SDE multiples.

Baseline range: 2.5x to 4x SDE for well-prepared brands. Strong consumer brands with high repeat purchase rates and multi-channel distribution trade at the higher end.

What moves the ecommerce multiple up:

• Repeat customer rate above 40%
• Multiple revenue channels (DTC website, Amazon, wholesale)
• No single supplier representing more than 30% of COGS
• Clean 3PL operations (not shipping from garages or founder's storage unit)
• Strong owned audience (email list, social following)
• Brand defensibility (proprietary formulas, unique designs, trademark)

What compresses it:

• Heavily Amazon-dependent (more than 70% of revenue from one platform)
• Seasonal revenue spikes without corresponding profit
• Inventory issues (excess, slow-moving, or supply chain fragility)
• Declining repeat customer rates
• Single product SKU with no expansion roadmap

Digital Agencies

Agencies are valued on SDE multiples but require more operational preparation than other business types.

Baseline range: 2x to 4x SDE. Strong retainer-based agencies with documented processes and stable client rosters trade near the top.

What moves the agency multiple up:

• High percentage of revenue on monthly retainer (vs. project-based)
• Average client tenure over 24 months
• Documented delivery processes that don't require the founder to be in every account
• Niche specialization (a performance marketing agency for med spas is more valuable than a generic digital agency)
• Client concentration below 15% per client

What compresses it:

• Founder is the primary client relationship for most accounts
• More than 50% of revenue is project-based (not retainer)
• Team turnover rate above 25% annually
• No documented SOPs; processes exist only in founder's head

What Destroys Valuation

These are the factors I see reduce transaction prices most reliably:

Customer concentration. A business where one client is 35% of revenue is not worth 3.5x SDE. It's worth whatever discount buyers require to accept the risk that that client leaves. I've seen businesses lose 40% of their asking price because of concentration issues that could have been fixed 18 months before going to market.

Key-person risk. If the business runs because of who you are. your relationships, your reputation, your expertise. and a buyer cannot plausibly replicate that, they will pay a deep discount or walk. The fix is not to disappear from the business. The fix is to document, delegate, and demonstrate that your role is trainable and replaceable.

Declining financials. Selling into a down year is the hardest situation in M&A. Buyers discount steeply for trajectory. A business doing $800K SDE this year that did $1.2M SDE last year is not a $2.4M to $3.2M business anymore. It is a business whose buyers are pricing in further decline. Sell on the way up, not the way down.

Messy financials. Every addback requires explanation and documentation. A founder who says "oh yeah, I ran my family vacation through the business" without receipts is inviting buyers to discount the entire earnings claim. Clean books are not optional for a high-value exit.

Real Ranges From Deals I've Done

I've sold enough businesses to have pattern recognition on what really trades at different multiples.

At the lower end of the range: businesses with solid revenue but meaningful concentration, owner dependency, or flat growth. They sell. They close. But they sell closer to 2.5x than 4x.

At the high end: businesses where the founder spent 12 to 24 months preparing. Clean books. Documented processes. Diversified revenue. A product or service that clearly works based on customer behavior (retention, NRR, repeat purchases). These businesses attract serious buyers, generate competitive dynamics, and close at multiples that would have surprised the founder if they'd sold two years earlier without preparing.

The single biggest variable is not the business. it is the process. A well-run competitive sale consistently produces prices 20% to 40% above what the same business sells for in a one-buyer conversation.

How to Use the Calculators

The valuation calculators on this site are built on data from our internal transaction comp set in lower-middle-market technology M&A. They give you a directional range, not a price, based on your revenue, margins, growth, and a handful of key risk factors.

Use the calculator as orientation. It will tell you if you're thinking about the right number or completely off base. It will not replace a proper valuation conversation, which accounts for context the calculator can't capture.

After the calculator, book a free call. I do valuation conversations all the time for founders who are 1 to 3 years away from selling. The earlier you understand your real number and what moves it, the more time you have to affect it.
