What Is a Business Actually Worth?
A business is worth the future profits it will hand its owners — and price is just the market’s current guess at that.
Two lemonade stands are for sale, each priced at $10,000. The first earns $1,000 a year in profit; the second earns $5,000 a year. Same price tag — but they’re obviously not the same deal. So how would you figure out what each stand is actually worth, as opposed to what it costs? Hold that question. Answer it and you’ve grasped the single idea that underlies how every stock, business, and investment gets valued.
Price vs. value, at the business level
You already know price and value aren’t the same. At the business level, the price is what the market currently charges (the last handshake from the previous lesson). The intrinsic value is what the business is genuinely worth based on the cash it will earn its owners over time.
The whole craft of valuation is estimating that intrinsic value, so you can compare it to the price and judge whether something is cheap, fair, or expensive. (This is a reasoning framework, not advice to buy or sell anything.)
Value flows from future profits
Why is a business worth anything? Because it will generate profits for its owners in the future. So its intrinsic value is essentially the sum of all those future profits — but adjusted for the time value of money: a dollar of profit ten years out is worth less today than a dollar this year, so future profits are discounted back to today’s terms.
That single idea — value = the worth, today, of the future cash a thing will produce — is the backbone of valuing stocks, bonds, rental properties, whole companies, almost anything.
The two lemonade stands, both priced at $10,000: • Stand A earns $1,000/year → at that rate the price equals 10 years of profit. • Stand B earns $5,000/year → the price equals just 2 years of profit. If both can keep earning, Stand B hands you your money back five times faster — far better value for the same price. Same sticker, very different worth.
A quick yardstick: the P/E ratio
A fast way to compare is the price-to-earnings (P/E) ratio = price ÷ annual profit (per share). It answers “how many years of current profit am I paying for?” A P/E of 10 means you’re paying $10 for every $1 of yearly profit.
Lower can look cheaper, higher can look pricier — but P/E is only a starting point, because a high P/E can be justified if profits are growing fast (you’re paying for tomorrow’s bigger profits, not just today’s). The number is a question-opener, never the whole answer. (Education, not a recommendation.)
Valuing a business is like valuing a rental property. You don’t price it on the paint color or the asking sign out front — you ask, “how much rent will this bring in over the years, and what is that income stream worth to me today?” A stock is the same: the price is the sticker, the value is the worth of the future income, and the P/E is basically “how many years of rent does the asking price equal?”
Putting a value on a share with P/E: 1. A company’s stock trades at $40 per share. 2. It earns $4 per share in annual profit (earnings). 3. P/E = $40 ÷ $4 = 10 → you’re paying about 10 years of current profit for the share. 4. Is that cheap or dear? It depends on the future: if profits are flat, 10 years is the deal; if profits are growing fast, the real payback is quicker and a P/E of 10 might be a bargain. The ratio frames the question — your judgment about future profits answers it.
