Valuing a private company involves using Income, Market, and Asset-based approaches, with key methods being Discounted Cash Flow (DCF) (income) and Comparable Company Analysis (CCA) (market), which compares it to similar public firms using multiples like EV/EBITDA. The DCF forecasts future cash flows, while CCA uses public market benchmarks, often requiring adjustments for size, risk, and lack of marketability common in private firms.
Common methods to value private companies include the Discounted Cash Flow (DCF) and the Comparable Company Analysis (CCA). Factors influencing private company valuations include financial performance, industry and market conditions, growth prospects, intellectual property, and customer base.
Method 1: Market-based valuations
A market-based valuation estimates the value of your business based on the value of similar businesses — ones of a similar size and in a similar industry. Market valuations may be based on comparisons to similar publicly traded companies or recent sales of comparable businesses.
A common business valuation ratio is the Price-to-Earnings (P/E) ratio, which is calculated as: P/E Ratio = Market Price per share / Earnings per share. This ratio is often used in the market-based valuation approach.
Revenue multiple is the most straightforward valuation method used on Shark Tank. It's typically the first thing the Sharks calculate when hearing a pitch. To calculate the revenue multiple, divide the proposed company valuation by annual revenue.
Service businesses typically sell for 2-3x their annual profit because they often depend heavily on the current owner's relationships and expertise. Manufacturing companies tend to command higher multipliers, often 4-5x their annual profit, due to their tangible assets and established processes.
Having 5% equity in a company means owning 5% of the company's total shares or value. As an equity holder, you are entitled to 5% of the company's profits (through dividends) and would receive 5% of the proceeds if the company is sold, after accounting for debts and liabilities.
Most of these rules of thumb are based on some multiple of revenue, sales, or earnings. Some are as simple as taking your small business' yearly cash flow and multiplying it by four. For example, if your business generates cash flow of $60,000 per year, it would have a value of $240,000.
High-end items (e.g., watches, cars, yachts) can have valuations manipulated through fictitious invoices or staged private sales. Criminals artificially raise or lower reported prices, disguising illicit proceeds as legitimate gains or concealing true wealth.
The calculation of net worth involves subtracting total liabilities from total assets. The basic formula is: net worth = assets – liabilities. This calculation gives us the value of the company's net worth at that specific point in time.
The price-to-book (P/B) ratio measures the market's valuation of a company relative to its book value, which equals total assets minus total liabilities (shareholders' equity).
12 common valuation mistakes
Allow us to introduce the “Four Pillars of Value”: revenue, cost, risk, and time. These pillars are not mutually exclusive but together form a robust framework to articulate and maximize value. Let's break them down and see how they specifically apply to the legal services industry.
The Rule of 40 states that, at scale, the combined value of revenue growth rate and profit margin should exceed 40% for healthy SaaS companies. The Rule of 40 – popularized by Brad Feld – states that an SaaS company's revenue growth rate plus profit margin should be equal to or exceed 40%.
Times revenue method
The multiplier typically ranges between 0.5 and 2, with lower values used for slower-growing industries and higher values for industries anticipated to grow rapidly. It's a good idea to consult with an independent financial advisor to determine the appropriate multiplier for your specific industry.
One of the biggest startup mistakes is poor cash flow management. About 82% of unsuccessful startups fail because they fail to properly manage their cash flow, or how much money is coming in and out of the business.
The founders who famously turned down a $30 million offer on Shark Tank were the sisters behind the dating app Coffee Meets Bagel (Dawoon, Arum, and Soo Kang) in 2015, with Mark Cuban offering to buy the whole company, the biggest in the show's history, but they declined to keep control and grow it themselves. As of 2025, their company's net worth was estimated at $150 million, with annual revenue around $36 million, showing they made a successful decision.
