Stock valuation calculator · free · cited to SEC filings
A stock valuation calculator that shows its work: intrinsic value from the filings, as a range
Type a ticker into three stock valuation calculators and you get three different fair values — and none of them shows the inputs. EvidInvest computes intrinsic value from the company’s own SEC filings with seven independent methods, shows the range they agree on, and links every input to the 10-K line it came from.
No account, no card, no trial. Sign-up is optional and adds alerts and saved work.
Why three sites give you three fair values
A single fair value is not a fact. It is the output of assumptions — a growth rate, a discount rate, which earnings figure, which share count — and a site that hides them is asking you to trust a number you cannot check.
One number hides the assumptions
Change the discount rate by one point and a DCF moves 20–30%. If you cannot see the rate, you cannot tell whether the number is careful or careless.
One number reads as a verdict
A “fair value” next to a price looks like a buy or sell signal. Analysts do not work that way: they hold a range and ask which methods agree.
One number has no source
Was the EPS diluted or basic? Trailing or forward? From the 10-K or a data vendor’s estimate? Without the filing behind it, you are valuing a rumour.
How the range is built
Filed inputs in, seven methods, one range out. Nothing is estimated by hand and nothing is hidden.
01 · Inputs from the filing
Revenue, diluted EPS, free cash flow, shares
Read from the company’s latest 10-K or 10-Q as filed with the SEC (20-F and 40-F for foreign filers). Each figure is shown with the form, period and filing date, and links to the document on sec.gov.
02 · Several methods, not one
Seven independent estimates
A DCF and a growth-trajectory DCF, P/E and P/B against the sector median, EV/EBITDA, EV/FCF, the Graham Number and Earnings Power Value. Each is weighted by how much it is trusted for that sector — and the weight is shown.
03 · A range, with agreement
Bear · base · bull
The 25th, 50th and 75th percentile of the methods that produced a usable estimate, plus how many of them agree and a confidence label. Prices are Cboe, 15-minute delayed, and every price says so.
The methods, and what each one is good for
Not every method fits every company. One that does not apply is shown as such on the page — never silently dropped.
- DCF — Projects free cash flow for the coming years and discounts it back to today. The most complete method, and the most sensitive to the growth and discount-rate assumptions.
- P/E vs sector — Trailing diluted EPS times the sector median P/E. What the stock would be worth if the market priced it like an average peer.
- Growth-trajectory DCF — A two-stage DCF that grows earnings at the company’s own EPS trend, then fades to the industry’s long-run rate.
- P/B vs sector — Sector median price-to-book times book value per share. Works for banks and asset-heavy businesses, says little about software.
- Graham Number — Benjamin Graham’s 1949 rule of thumb: √(22.5 × EPS × book value). It punishes asset-light companies, so it reads low for big tech.
- EV/EBITDA — Values the whole business at 10× EBITDA and divides by the share count. A mid-cycle industrial multiple; fast growers trade far above it.
- EV/FCF — 20× free cash flow per share, i.e. a 5% cash yield. Reads low for companies the market expects to keep growing.
- Earnings Power Value — Greenwald’s Earnings Power Value: what current earnings are worth if they never grow. Everything above it is what you pay for growth.

Bear, base and bull are the 25th, 50th and 75th percentile of the methods that produced a usable estimate. Weights say how much a method is trusted for this sector; they do not change the range.

What this calculator is not
- Not a buy or sell signal. A range above or below the price is a question to investigate, not an instruction. We never publish price targets.
- Not a forecast. The inputs are what the company filed, not what anyone hopes it will earn. Methods that do not credit future growth read low for fast growers — the method table says which ones, and why.
- Not for tips. If you want someone to tell you what to buy this week, this is the wrong site. If you want to know what the filings say a business is worth, it is the right one.

Questions people ask before they trust a number
- Is “fair value” the same as intrinsic value?
- We use them interchangeably: an estimate of what the business is worth per share from its own financials, independent of the current price. The range is the honest form of that estimate — several methods, each with different blind spots.
- Which filing are the numbers from?
- The latest annual (10-K) or quarterly (10-Q) statement in SEC EDGAR, 20-F or 40-F for foreign filers. The filing card on every page names the form, the period and the filing date and links to sec.gov.
- How often does it update?
- Statements, prices and models refresh nightly at 04:00 UTC. New filings appear the night after EDGAR publishes them.
- Why is the base estimate far below the price for some growth stocks?
- Because several of the methods (Graham Number, EPV, EV/FCF) value only what a company earns today and give no credit for growth. For a company the market prices on the next five years, those read low by design. That is why the page shows every method with its weight instead of one blended number — read the table, not the midpoint.
- Do you use analyst estimates?
- No. Fundamentals are SEC-filed only, 2009 onward. There are no consensus numbers on the site.
