   Calculate Seller's Discretionary Earnings (SDE)

   SDE is the foundation of online business valuation. SDE is the annual cash flow available to a full-time owner-operator: start with net profit, then add back the owner's salary (or the value of the owner's time), any one-time or non-recurring expenses that won't recur under new ownership, and non-cash charges like depreciation. Subtract any owner perks that inflated expenses (e.g., a personal car the seller ran through the business). The result is the normalized earnings available to you as the new owner — before you pay the purchase price. For content sites, SDE is calculated from advertising revenue, affiliate commissions, and sponsorships minus hosting, software, content production costs, and your adjusted owner time. For SaaS, SDE is MRR × 12 minus infrastructure, software, and support costs. For eCommerce, it is gross revenue minus COGS, fulfillment, advertising, and returns. Always use Trailing Twelve Months (TTM) as your SDE baseline — it smooths seasonality and uses actual results rather than projections.

   Apply the baseline multiple for the business type

   The asking price is almost always expressed as a multiple of monthly SDE (e.g., 36x monthly SDE) or annual SDE (e.g., 3x annual). The multiple varies by business type, revenue quality, and market conditions. As of 2026, typical baselines are: content sites 25-40x monthly SDE (roughly 2-3.3x annual), driven by display advertising and affiliate income but susceptible to Google algorithm updates; SaaS businesses 35-55x monthly SDE (3-5x annual) for profitable micro-SaaS with under $500k ARR, reflecting contractual recurring revenue and gradual churn risk rather than overnight disruption risk; eCommerce and FBA stores 25-45x monthly SDE, varying based on supplier concentration, advertising dependency, and inventory complexity; newsletters 20-35x monthly SDE, driven by open rate, monetization model, and subscriber list hygiene; service businesses 18-30x monthly SDE, compressed by client concentration and key person risk. Convert to annual to compare: 36x monthly = 3x annual SDE.

   Adjust upward for revenue quality and diversification

   Not all SDE is equal. Revenue quality is the single biggest determinant of where within the multiple range a business sits. High-quality revenue earns a premium: recurring subscription revenue (monthly/annual subscribers paying on schedule) is more predictable than one-time purchases; diversified revenue across multiple channels (e.g., display ads + affiliate + sponsorships) is safer than single-source revenue; verified revenue with matching payment processor statements, GA4 data, and P&L records earns a premium over unverified screenshots. Downward adjustments apply when: more than 50% of revenue comes from one source (single affiliate program, one advertiser, one client), revenue is seasonal with a deep Q1-Q3 trough, or revenue is trending down over the trailing 6-12 months. A business at the high end of the multiple range has recurring, diversified, independently verified revenue that does not depend on any single platform, advertiser, or client.

   Evaluate growth trajectory

   Buyers pay for trajectory as much as current earnings. A business generating $3,000/month SDE with 30% year-over-year growth is worth significantly more than an identical business with flat or declining SDE, because you are buying the future cash flows the business will generate under your ownership. Calculate year-over-year growth rate by comparing trailing twelve months against the prior twelve months. Calculate the month-over-month trend to assess whether the business is accelerating or decelerating. A documented 20%+ annual growth rate earns a multiple premium of 3-8x monthly SDE above the category baseline. A business declining 10%+ year-over-year should trade at the low end of multiples, or you should apply a haircut to the multiple and reduce your offer. Be skeptical of hockey-stick growth in the last 2-3 months — verify what caused it (seasonal spike, new affiliate deal, or structural improvement) before incorporating it into your valuation.

5. 5

   Discount for platform and concentration risk

   Every website has concentration risk — dependence on a single channel, platform, client, or revenue source. The greater the dependence, the greater the risk, and the lower the multiple should be. Google organic search dependence: a content site generating 90%+ of traffic from Google search is highly susceptible to algorithm updates — a single Google core update can reduce organic traffic by 30-70% overnight. Sites with 60%+ organic search traffic that also have strong social, email, or referral channels are safer. Amazon Associates: affiliate revenue from Amazon's Associates program cannot be transferred directly; the program is non-transferable between accounts, and Amazon has historically reduced commissions without notice. Single-client revenue: a service business or newsletter generating 40%+ of revenue from one client or sponsor has concentration risk that should compress the multiple by 20-30%. Platform risk: SaaS built on a single payment processor, hosting provider, or API dependency (e.g., 100% of functionality relies on a third-party API that could be deprecated) warrants a multiple discount.

   Measure operator time and systematization

   Operator time is the second most important multiple driver after revenue quality. A website requiring 40+ hours per week from the current owner is a job, not an investment — it will require you to pay yourself a salary or hire a replacement, which directly reduces your return. A website running on documented Standard Operating Procedures (SOPs) with under 5 hours per week of owner involvement can command a significant multiple premium because it is genuinely passive income. Assess operator time by: requesting the seller's honest time audit (hours per week and task breakdown), evaluating whether the current owner's tasks are replaceable by a VA or contractor (content editing, customer support, ad management) or require specialized expertise (technical development, key client relationships), and assessing whether SOPs exist for every repeatable task. Calculate the annualized cost of replacing the seller's time at a market wage for a contractor and subtract it from reported SDE to arrive at a 'systematized' SDE. The resulting lower SDE gives you a more accurate picture of the investment's economics.

7. 7

   Cross-check with a DCF analysis for larger acquisitions

   For acquisitions above $100,000, sanity-check the SDE multiple against a simple discounted cash flow (DCF) model. Project out 5 years of SDE using the current TTM SDE and the business's growth rate (or a conservative estimate if growth has been volatile). Discount those cash flows back to present value using a discount rate of 25-35% (online businesses carry higher risk than traditional businesses, justifying a higher discount rate than, say, a 10-year Treasury). Add a terminal value representing what you could sell the business for in year 5. Compare the sum of discounted cash flows plus terminal value to the asking price. If the DCF supports the asking price only under aggressive growth assumptions that the business has not yet demonstrated, the asking price is optimistic and should be negotiated down. The SDE multiple method is faster and more common in the sub-$1M market, but the DCF provides a useful reality check: a 4x annual SDE multiple means you are paying 4 years of earnings with no time-value adjustment — only defensible if you expect significant growth in years 3-5.

   Arrive at a bid range and build in your margin of safety

   Valuation is not a single number — it is a range. After completing the steps above, you should have a low-end valuation (applying conservative adjustments for risk, declining trends, and unverified revenue claims), a midpoint valuation (applying the category baseline multiple to verified TTM SDE with appropriate risk adjustments), and a high-end valuation (applying an above-average multiple for strong revenue quality, growth trajectory, and low operator time). Your opening offer should start at or slightly below the midpoint valuation and should leave room to concede toward the high end during negotiation. Never pay above your maximum valuation — this is your margin of safety. Build in the cost of due diligence, legal review, and transition-period costs before finalizing your bid range. The most common mistake buyers make is anchoring to the asking price rather than arriving independently at their own valuation and making an offer based on what the business is worth to them.

Common questions about valuing a website

How much is my website worth?

Most websites are valued at 25-55x monthly SDE (Seller's Discretionary Earnings), depending on business type. A content site generating $1,000/month in SDE (after hosting, content costs, and tools) would typically list for $25,000-$40,000. A SaaS business generating $1,000/month SDE might list for $35,000-$55,000 due to the higher revenue quality premium. To get a more precise estimate, calculate your trailing twelve months (TTM) SDE, then multiply by the appropriate category multiple. Key factors that push you toward the top of the range: recurring revenue, low owner time (under 5 hours/week), diversified traffic and revenue sources, and documented year-over-year growth.

What is the right multiple for different types of websites?

As of 2026: Content sites (blogs, affiliate sites, display advertising): 25-40x monthly SDE (2-3.3x annual). SaaS and software tools: 35-55x monthly SDE (3-5x annual) for profitable businesses, up to 6-8x ARR for high-growth. eCommerce and Amazon FBA: 25-45x monthly SDE, varying by inventory complexity and advertising dependency. Newsletters: 20-35x monthly SDE, driven by open rate and monetization model. Online communities: 20-35x monthly SDE, driven by member engagement and subscription MRR. Service businesses: 18-30x monthly SDE, compressed by client concentration and key person risk. These are market baselines — individual businesses trade above or below based on revenue quality, growth, risk profile, and transferability.

How do I calculate SDE for a website?

SDE (Seller's Discretionary Earnings) = Net Profit + Owner's Salary or Time Value + Add-Backs - Owner Perks. Step 1: Start with the business's net profit from the P&L. Step 2: Add back the owner's annual salary if they pay themselves one (or add back the dollar value of their time at a fair market wage). Step 3: Add back one-time, non-recurring expenses that won't continue under your ownership — for example, a one-time legal fee, a website redesign cost, or a promotional expense that won't repeat. Step 4: Add back non-cash charges like depreciation if any exist. Step 5: Subtract any personal expenses the seller ran through the business (car, travel, etc.) that you won't have. The result is the annual cash flow available to you as the new owner. Always use trailing twelve months (TTM) as the base period.

Should I use TTM or run rate to value a website?

Use TTM (Trailing Twelve Months) as the primary basis in almost all cases. TTM uses actual, verifiable results across a full year — smoothing seasonality and capturing the full cost cycle. Run rate (annualizing recent months) is only appropriate when there is a documented, provably structural change in the last 2-3 months — for example, a signed recurring sponsorship deal or a pricing increase on existing subscribers. Run rate is almost always seller-favorable and should be treated skeptically. If the seller insists on a run rate multiple for a business showing a recent revenue spike, negotiate an earnout structure: pay the baseline TTM multiple at close and pay the run-rate premium only if revenue sustains at the elevated level for 12 months after closing.
