Price Per Share Calculator

Background.

A valuation model rarely ends with a number you can hold up against a stock quote. A discounted cash flow or a comparable-company analysis usually produces enterprise value, what the whole operating business is worth to everyone who funds it, and getting from there to something comparable with a share price takes two more moves: take out what belongs to lenders and other senior claims, then split what remains among the shares.

The second move happens here. Total equity value is divided by the diluted share count, and the answer is the implied value of one share in dollars. If it sits well above the market price, the model says the stock is cheap; well below, expensive — but only as far as the model's own assumptions hold.

The word doing the work is diluted. Basic shares outstanding counts stock already issued. A diluted count adds the shares that would appear if in-the-money options and warrants were exercised, restricted stock units vested and convertible securities converted. Leave them out and the per-share value is overstated, because the same equity would in fact be shared among more holders; for a company that pays its staff heavily in stock, the gap can be wide.

Two slips cause most wrong answers. One is entering enterprise value instead of equity value, which quietly hands lenders' money to shareholders: subtract debt, preferred stock and minority interests and add back cash first. The other is pairing an equity value at one date with a share count from another.

The division assumes a single class of common stock sharing equally. Where preferred shares carry liquidation preferences, as in most venture-backed companies, common holders are paid only after those claims, and a waterfall analysis is needed instead.

What is price per share calculator?

Implied value per share is the equity value of a company divided by its diluted share count: the common shares already issued plus the net new shares that options, warrants, restricted stock units and convertible securities would create. It is the price one common share is worth according to whatever valuation produced the equity figure, so it inherits every assumption of that valuation. Set against the market price, it shows the premium or discount the model implies.

How to use this calculator.

1. 01Enter total equity value in dollars, the value belonging to common shareholders. If your model stops at enterprise value, subtract debt, preferred stock and minority interest and add cash before entering it.
2. 02Enter diluted shares outstanding as a count. The cover page of the latest 10-K or 10-Q gives basic shares outstanding; add the net shares from options, warrants, RSUs and convertibles, for example with the treasury stock method.
3. 03Keep both inputs on the same scale. Equity in millions of dollars divided by shares in single units gives a figure a million times too small; use full figures for both, or millions for both.
4. 04Compare the result with the current share price: (implied value − market price) ÷ market price is the upside or downside the model implies.

The formula.

Value per share = E ÷ N, where E is total equity value in dollars and N is the diluted number of shares. Nothing else enters the calculation: no discounting, no control premium, no adjustment between share classes. The answer moves in proportion to E and inversely with N, so overstating equity value by 10% raises the per-share figure by 10%, while issuing 10% more shares cuts it by about 9.09% (1 ÷ 1.1). E may be negative, as when debt exceeds the value of the business, and the result is then negative too; read that as a sign common shareholders would receive nothing, not as a price, because a shareholder cannot lose more than the investment. N must be above zero.
