Aether Value Calculator
What a stock is worth on your assumptions — five valuation methods, a reverse DCF, and a football-field range. Arithmetic you control, never a prediction.
Save, Excel and PDF are Pro features — the calculator itself is free.
The basics
Enter any two of share price, shares and market cap — the third is calculated. Enterprise value and a liquidity line follow.
—
Market cap + debt − cashLiquidity

What today's price already assumes
The reverse DCF solves for the growth rate the current price implies, holding your other inputs fixed. Then a base-rate check on every growth input you type.
Not meaningful for this company
Free cash flow is zero or negative — the DCF terminal value breaks down.
Base-rate check on your growth inputs
Enter a growth rate to check it against history.

Five methods, side by side
Earnings multiple
EPS × P/E
Not meaningful for this company
EPS is zero or negative — P/E is not meaningful for a loss-making company.
EV / EBITDA
(EBITDA × multiple − net debt) ÷ shares
Net debt — · shares —
Not meaningful for this company
EBITDA is zero or negative.
Free cash flow yield
FCF per share ÷ required yield
Not meaningful for this company
Free cash flow per share is zero or negative — the yield is undefined.
Two-stage DCF
10-yr FCF, fading to terminal, discounted
Not meaningful for this company
Free cash flow is zero or negative — the DCF terminal value breaks down.
Dividend discount
D₁ ÷ (r − g)
Not meaningful for this company
No indicated dividend — the dividend discount model applies only to payers.
Margin of safety
The price at which the average base case would offer the margin you set.
—
Base case = average of the methods that apply. Arithmetic on assumptions you control.
The range — value on your assumptions
Not enough inputs to draw a range yet.
Arithmetic on assumptions you control, not a prediction. Change an input and the answer changes.
How each method works, and when it doesn't
This calculator does arithmetic on assumptions you control. It never predicts a price, and it never tells you a stock is "undervalued" or "overvalued". Change an input and the answer changes. Each method values the same business from a different angle, so the range between them is informative.
Earnings multiple (P/E)
Multiplies earnings per share by a P/E ratio you choose. It assumes the company is profitable and that its P/E is stable; it does not work for loss-making companies, where EPS is negative or meaningless, and it ignores balance-sheet strength and growth.
EV / EBITDA
Values the whole enterprise (debt plus equity) as a multiple of EBITDA, then subtracts net debt and divides by shares. It adjusts for capital structure, but it is not meaningful for banks and insurers, whose debt is a raw material rather than financing, and whose core earnings are not EBITDA-like.
Free cash flow yield
Divides free cash flow per share by the return you require. It rewards companies that turn profit into cash; it is not meaningful for companies with negative or highly volatile free cash flow, where the yield is undefined or misleading.
Two-stage discounted cash flow
Projects free cash flow for ten years, fading growth to a terminal rate, then discounts everything back at your required return. It is the most complete method and the most sensitive: small changes in growth or the discount rate move the answer a lot. It is not meaningful when free cash flow is negative today and expected to stay so, because the terminal value breaks down.
Dividend discount
Values a share as the present value of its future dividends, growing at a rate you set. It applies only to dividend payers with a stable payout; it is not meaningful for non-payers or companies that fund dividends with debt.
Where a method does not apply to a company, the tool shows "not meaningful for this company" instead of a number.
Not financial advice. Valuations depend entirely on the assumptions you enter. Default inputs are pre-filled from delayed market data and SEC EDGAR / FMP fundamentals; edit any of them.
