What Is a Business Valuation and How Do Buyers Calculate It? A business valuation is a supportable estimate of what a business is worth, as of a specific date, to a specific type of buyer, under stated assumptions. It is not a single fact about your company. Change the purpose, the buyer, or the date and the number legitimately changes. That is the part owners find hardest to accept. You can have a bank valuation, a divorce valuation, a gift tax valuation, and a purchase offer for the same business in the same year, all four defensible, all four different. Here is how the number actually gets built. The Three Approaches an Appraiser Uses Every credible valuation runs through the same three lenses, then weights them based on the facts. The income approach values the business on the earnings it can be expected to produce, either by capitalizing a single year of normalized earnings or by discounting projected cash flows back to present value. This governs when the business has stable, predictable profit and an operating history to support a projection. The market approach values it against what comparable businesses actually sold for, expressed as a multiple of earnings or revenue. This governs when there is real transaction data for similar companies in similar size ranges, which is why it dominates in small and mid-market deals. The asset approach values the assets net of liabilities. It governs for asset-heavy, marginally profitable, or holding companies, and it functions as a floor. A profitable operating business worth less than its net assets is telling you something about the operations. For most owner-operated businesses, the market approach drives the answer and the other two serve as sanity checks. Where the Number Really Comes From in Small Deals Strip away the formality and most small-business pricing is one equation: normalized earnings times a multiple. Normalization is where the work is. A buyer rebuilds your earnings to reflect what the business would produce under a normal owner, which means adding back personal expenses run through the company, removing one-time items in both directions, adjusting owner compensation to market rate, restating related-party rent to market, and correcting accounting that does not hold up such as revenue recognized too early or inventory that was never counted. Owners consistently underestimate this step. Two businesses reporting identical net income can normalize to numbers 30 percent apart, and the adjustments are negotiated line by line during diligence. This is also why messy books cost real money at...
