What’s my business roughly worth?
Not a formal appraisal. Just a back-of-envelope estimate based on how small businesses are actually bought and sold. Here's the math buyers use and how to run it on your own numbers.
The short answer
What is your business worth?For most small businesses: annual Seller's Discretionary Earnings (SDE) multiplied by an industry-specific multiple (typically 1.5x to 4x). SDE = net income + owner salary + depreciation + non-recurring expenses. A $150K SDE business in a 2.5x industry is worth roughly $375,000.
Why SDE multiples are how small businesses are actually valued
Large companies are valued on EBITDA. Small businesses (under $5M in revenue) are valued on SDE because the owner's compensation is a discretionary expense. A new owner might pay themselves more or less, so SDE strips out the owner's total economic benefit to show the true cash-generating power of the business.
The multiple depends on industry, growth rate, owner dependence, and customer concentration. BizBuySell's annual data shows the median small business sells for about 2.3x SDE, but the range is wide: some sell for 1.2x (struggling, owner-dependent) and others for 4x+ (growing, recurring revenue, team-run).
This is not a formal valuation. A business broker or appraiser will go deeper. But it gets you within 20-30% of reality, which is enough to inform your decisions about whether to invest in growth, take distributions, or start planning an exit.
How to estimate your business value step by step
- 1Calculate annual SDE from your P&L
In QuickBooks or Xero, run a Profit and Loss for the last 12 months. Start with Net Income. Add back: your salary, personal benefits, personal expenses run through the business, depreciation, and any one-time costs. That is your SDE.
- 2Find comparable multiples on BizBuySell
Go to BizBuySell.com and search for recently sold businesses in your industry and size range. Look at the asking price relative to cash flow. Also check the BizBuySell Insight Report for median multiples by industry.
- 3Adjust the multiple for your specific factors
Start with the industry median. Add 0.25-0.5x if revenue is growing 15%+ per year. Subtract 0.25-0.5x if you are highly owner-dependent (you personally deliver most of the work). Subtract 0.25x if your top client is 30%+ of revenue.
- 4Calculate the range
Multiply your SDE by the adjusted multiple. Use a range (e.g., 2.0x to 3.0x) rather than a single number. If SDE is $150,000 and your adjusted range is 2.0x to 3.0x, your business is worth roughly $300,000 to $450,000.
Total time: 30-60 minutes. The SDE calculation takes 15 minutes. Finding good comparables on BizBuySell takes another 15-30 minutes. Adjusting the multiple is judgment.
Five factors that move your valuation multiple up or down
- Revenue growth rate. Growing businesses command higher multiples because the buyer is purchasing future earnings, not just current ones.
- Owner dependence. Can the business run without you for 30 days? If not, the value is heavily discounted because the buyer is inheriting a job.
- Revenue concentration. High concentration in one or two customers is risky for a buyer. If they leave post-sale, the business implodes.
- Recurring vs. project revenue. Businesses with recurring revenue (subscriptions, contracts, retainers) are worth more than businesses that start from zero each month.
- Industry trends. A business in a growing industry commands a premium. One in a declining industry gets discounted.
