Methodology
How TickerMath computes its numbers
Every figure on this site comes out of a formula you can check. This page is all of them — the inputs, the arithmetic, the thresholds, and the places we decline to answer. If a number here ever surprises you, the reason is on this page.
Where the numbers come from
Company figures come from SEC EDGAR — the filings themselves, in the structured form companies are required to publish. No data resellers, no scraped websites, and no AI generating figures. They are pulled from those filings and checked before anything publishes.
Share prices are the one thing filings cannot give us. Those are entered and verified by hand, and every read states the date of the price it used. A price is never live and never moves during the day.
The value read
We estimate what a business is worth by asking what cash it can hand its owners, and what that cash is worth today. Money arriving in ten years is worth less than money arriving now, so future cash is discounted back.
Free cash flow is operating cash flow less capital expenditures, both exactly as filed. It is the cash left after a company has paid to keep itself going and to grow.
value of the business =
the next 10 years of free cash flow, each grown 5% a year and discounted at 9%
+ a terminal value for everything after year 10, growing 2.5% a year forever, discounted at 9%
fair value per share = (value of the business + net cash) ÷ diluted shares
Those three parameters — 5% growth, 2.5% terminal growth, 9% discount rate — are the whole model. They are deliberately unexciting and identical for every company, so a read reflects the company's own cash flows rather than our optimism about it.
The range beside each fair value is the same model run pessimistically and optimistically: 3% growth discounted at 10% at one end, 7% growth discounted at 8% at the other.
Net debt
We value the business, then subtract what it owes net of what it holds — borrowings, commercial paper and finance leases, less cash and marketable securities. What is left belongs to shareholders, and that is what gets divided by the share count.
The reason is simple: a shareholder stands behind the lenders. If a company owes $139B, the owners do not get the first $139B of value — the lenders do. Operating leases are shown but never counted as debt; they are a contract for future use rather than money borrowed.
This is one of the main reasons a TickerMath number runs lower than a site that values the business and stops there. On a heavily indebted company the two answers are miles apart, and every read carrying real debt says so in its own words.
When a year lies
A single year is not a level. Companies pay legal settlements, deposit money with tax authorities, settle an acquisition — and the year that happens in tells you about the event, not about the business.
So before valuing anything we compare the latest year of free cash flow against the company's own typical level: the median of the last 5 years. If the latest year sits more than 30% away from that and the company has not simply been travelling that way all along, the read uses the typical level instead, and the page says so in plain words — including the size of the difference.
The rule is symmetric. One unusually great year is treated exactly like one unusually terrible one, because a one-off high makes an expensive company look reasonable and that is the error that costs a reader money.
The second half of the test matters as much as the first. A company that is growing fast puts every year far above its own trailing median — that is what growth is, not a distortion, and its latest year stands. The same applies to a business in long decline: we do not average a real decline away to make it look better.
Implied growth: what the price is betting on
Turn the model around. Instead of asking what a company is worth, ask what growth rate would make today's price exactly right. That is the implied growth, and it is often the most useful line on the page: it converts "is this expensive?" into "do I believe this company can grow that fast?", which is a question you can actually judge.
The solver searches up to 40% a year. Past that we say more than 40% rather than invent a figure — quoting the edge of a search as though it were the answer would understate exactly the thing the line exists to point at.
The lights and the verdict
Five lights, each a rule with a stated threshold, no judgement involved:
- Valuation. Green when fair value sits more than 15% above the price, red when it sits more than 15% below, amber in between.
- What the price assumes. Compares the implied growth against the company's own three-year record.
- Revenue. Growing or shrinking, latest year against the one before.
- Cash flow. Whether free cash flow is compounding or flat-to-down.
- Balance sheet. Green with net cash; red when net debt is more than 4× annual free cash flow; amber between.
The verdict at the top is computed from those lights. Nobody types it. That is why it is sometimes blunt about a company everyone likes.
The moat read
A second lens, over ten fiscal years, asking whether a business has a durable edge rather than whether it is cheap today.
- Return on invested capital. Operating profit after tax, divided by average invested capital — equity plus borrowings and commercial paper, less cash. Held above 15% in at least 8 of the ten years is the mark of a real edge; above 12% is solid but not dominant.
- The one-dollar test. For every dollar the company kept rather than paid out, how much did profit rise?
- Margin stability. A gross margin that holds through a decade is pricing power; one that drifts down is competition.
- Share count. Falling means owners are getting a bigger slice; rising means the opposite.
What we refuse to do
103 companies have a read. 48 have a page that explains why they do not, and that is a feature we are proud of rather than a gap.
Banks, insurers, property trusts and regulated utilities get no fair value, because the free-cash-flow model does not describe them. A bank's cash flow is its business; a utility is supposed to outspend its cash flow. Running the model anyway would produce a confident-looking number that means nothing, and a confident wrong number is the one thing this site exists not to produce.
Some companies are held back for a duller reason: a figure we need is missing from the filings. Those pages name the missing number. We never estimate one to fill a gap.
Why our numbers often run lower than other sites
This is the question we get most, so here it is flatly. Three differences, all deliberate:
- We grow the filed record, not forecasts. Our growth rate is a fixed 5% applied to what a company has actually reported. Sites built on analyst estimates start from what a company is expected to earn, which is usually more.
- We discount free cash flow, not earnings. Earnings are an accounting result; free cash flow is what is left after the company pays for its own plant and equipment. For a capital-hungry business the gap is enormous.
- We subtract net debt. Many published fair values are the value of the business, full stop. Ours is the value of the business less what it owes.
None of that makes us right and them wrong. It makes the numbers different by design, with the assumptions on the table so you can decide which set you trust.
When we're wrong
We compute one model, honestly, and it can be wrong. Sometimes the model does not suit a company as well as we thought; sometimes we find a mistake in how a figure was read. When that happens we fix it and the numbers change.
That is the tool working, not the tool failing. It is also why watchlist alerts exist: when a number moves, the people following that company hear about it rather than discovering it by accident.
