Why book value matters to a first-time founder
Book value is the figure in the accounts. For the whole company, assets minus liabilities is the equity book value on the balance sheet. For one asset, it is usually cost less depreciation or other write-downs, called the carrying amount. A buyer, a lender, or an investor may pay something quite different. Treat the accounting figure as cash you could raise tomorrow and the decision goes wrong.
Examples of book value
A furniture maker in Malmö has assets of SEK 9 million and liabilities of SEK 4 million, so equity book value is SEK 5 million. One machine cost SEK 1.2 million and has accumulated depreciation of SEK 700,000, so its own book value is SEK 500,000. A dealer offers SEK 150,000 for it. Both figures can be right. One is accounting. The other is a market offer.
Common misunderstanding
Book value is not the resale price, and it is not the valuation an investor just offered for the company. Assets minus liabilities is the equity book value, not a second kind of worth sitting beside the accounts. One asset’s book value is not the company’s equity book value. A brand built inside the firm often does not appear as an asset at all.
When to use it
Use it when you read a balance sheet, test an asset for a loss of value, or set accounting equity next to a funding offer. Say whether you mean the whole company or one asset. When the question is what someone will pay, use an offer or a market price.
