The Intrinsic Value Calculator — A Step-by-Step Guide
There's an old line from Warren Buffett that the calculator on this page is built
around: "Price is what you pay. Value is what you get." The market quotes you a
price every second of the trading day. What it never hands you is an independent
estimate of value — what the business might actually be worth based on its
fundamentals. The Intrinsic Value Calculator exists to produce exactly that
estimate, with three time-tested measures blended into one fair value, and to line it up next to the live price so
you can see the gap.
This guide walks through the whole page — what you type in, what comes back, and how
to read each card — with one idea kept in view throughout:
TyBuff is an analytical platform, not a financial adviser. Every figure here is
an estimate produced by a mathematical model from public data. It is for research
and educational use — not investment advice, and not a signal to buy or sell. The
page tells you what the formulas compute; what you do with it is your decision.
What "intrinsic value" actually means
Intrinsic value is an estimate of what a stock is truly worth based on its
financial fundamentals, independent of its current market price. The logic is
simple:
- If the estimated intrinsic value is higher than the market price, the stock
may be undervalued. - If it's lower, the stock may be overvalued.
The word doing the heavy lifting is estimate. Reputable models can disagree sharply
on the same company — which is exactly why this page runs several of them and shows you
each, rather than pretending there's a single right answer.
Step 1 — Run an analysis
At the top of the page is a small search card with two inputs:
- Ticker — type a symbol or company name (e.g.
AAPL,MSFT,TSLA). An
autocomplete dropdown suggests matches as you type; use the arrow keys and Enter,
or click a suggestion. - Custom Growth Rate % (optional) — the expected annual EPS growth rate the
models should assume. Leave it empty and the page auto-estimates it from analyst
EPS forecasts (the placeholder shows you the auto value, e.g. "~9.0% auto-estimated").
Type your own number if you want to stress-test a more conservative or more
aggressive assumption — this is the single biggest lever you control, so it's worth
trying a few values.
Press Analyze and the results render below.
A note on access
The Intrinsic Value Calculator is a feature of the Advanced and Professional
plans. On the Essential plan you can still explore it with a set of demo tickers
(AAPL, MSFT, GOOGL, JNJ) to see exactly how it works before deciding whether to
upgrade.
Step 2 — Read the summary card
The first result card is the headline: the ticker, the company name, and four numbers
side by side.
- Current Price — the latest market price, with its date.
- Graham Value — the fair value from Graham's revised formula (more on this below).
- DCF Value — the fair value from a Discounted Cash Flow model.
- Verdict — a plain-language read based on the Owner-Earnings Fair Value (our
DCF-weighted blend, explained under the gauge below) versus the current price: - Potentially Undervalued — price sits more than 15% below the fair value.
- Potentially Overvalued — price sits more than 15% above it.
- Near Fair Value — price is within that ±15% band.
- If the inputs are missing, you'll see Insufficient data instead — common for
companies the models simply don't fit (see the limitations at the end).
The colors are a quick visual cue (green leaning cheap, red leaning expensive, amber
in between), not a rating. Two shortcut buttons sit underneath: Open Full
Fundamentals (the complete financial table) and Go to Detail Page (the
instrument's full detail view with charts).
Step 3 — The Fair Value gauges
Below the summary is the headline of the whole page: a large primary gauge, with three
smaller figures beneath it.
The primary gauge — Owner-Earnings Fair Value
The big gauge (marked "Primary estimate") shows the Owner-Earnings Fair Value.
This is the number the Verdict and the gauge needle are built on. Rather than a plain
average, it's a weighted blend that deliberately leans on the model closest to how
Graham and Buffett actually thought about value:
- 50% — the DCF (owner earnings). Buffett valued a business by the cash it generates
for its owners over time; the DCF, built on Free Cash Flow, is the closest proxy, so it
carries the most weight. - 25% — Graham's growth value (the revised formula below).
- 25% — the Graham Number (Graham's strict defensive ceiling, also below).
When one of those measures isn't available for a company, the remaining weights
re-balance automatically.
- The needle swings from "Undervalued" (left) to "Overvalued" (right) according to
how far the current price deviates from that fair value. - The Margin of Safety percentage quantifies the gap: a positive margin means the
price is below the estimated fair value; negative means it's above. This is the
cushion Graham insisted on and Buffett practised his whole career — buying only when
price sits comfortably below value.
The three secondary figures
Underneath, three compact cards show the same business through different lenses, so you
can judge for yourself instead of trusting a single number:
- Graham + DCF blend — a simple 50/50 of Graham's growth value and the DCF.
- All-three average — the plain average of Graham growth, the Graham Number, and the DCF.
- DCF only — the pure owner-earnings view, with no Graham input.
When the figures broadly agree, the estimate is more robust. When they diverge
widely, the valuation is highly sensitive to assumptions — and deserves a wider margin of
safety.
Step 4 — The valuation models, side by side
This is where the page shows its work. Two cards sit next to each other.
Graham's Intrinsic Value
Named for Benjamin Graham, the "father of value investing" and the author of The
Intelligent Investor (and Buffett's teacher at Columbia). The card shows the revised
Graham formula right at the top:
V = EPS × (8.5 + 2g) × 4.4 / Y
and then breaks out every input so nothing is a black box:
- EPS — earnings per share. The page prefers the 7-year average (Graham
recommended smoothing out cyclical ups and downs) and falls back to trailing
twelve months (TTM) when the longer history isn't available. - Growth Rate Used (g) — the annual EPS growth assumption (your custom value, or
the auto-estimate from analyst forecasts). We cap g at 15%: the2gterm makes the
formula explode with growth, and Graham himself was deliberately conservative and warned
it must never be applied mechanically with sky-high growth numbers. - Multiplier (8.5 + 2g) — 8.5 is Graham's base P/E for a no-growth company; the
2gterm adds value for expected growth. - Bond Yield Adjustment (4.4 / Y) — Graham's original 4.4 was the AAA corporate
bond yield of his era; dividing by today's yield (Y, around 5.5%) re-anchors the
formula to the current interest-rate environment. - Intrinsic Value — the formula's output.
- Margin of Safety — how far below (or above) that value the price sits. Graham
famously recommended only buying with a margin of at least 25–30% — a cushion
against the inevitable errors in any estimate.
The same card also shows a second, separate Graham measure:
- Graham Number — the classic √(22.5 × EPS × Book Value per share). It comes from
Graham's two defensive screens — a P/E no higher than 15 and a price-to-book no higher
than 1.5 (15 × 1.5 = 22.5) — and represents the maximum a defensive investor should
pay. It is far stricter than the growth formula above, so the two rarely agree
(especially for growth stocks), and it's intentionally conservative. It's shown as
N/A when a company has negative earnings or book value — which is itself a Graham
red flag.
DCF Valuation
A Discounted Cash Flow projects a company's future cash and discounts it back to
what it's worth today. The card states which inputs it used:
- FCF/Share — it prefers Free Cash Flow per share (cash left after capital
spending — a cleaner read on real cash generation, and the closest proxy to Buffett's
"owner earnings") and falls back to EPS when FCF isn't available; the card tells you
which one it's using. - Discount Rate (11%) — the rate future cash is discounted at; 11% is a common
industry standard. - Terminal Growth (2.5%) — the assumed perpetual growth rate after the 5-year
projection window. We anchor it near long-run inflation, because no company can grow
faster than the economy forever — a looser figure lets the terminal value dominate and
inflates the valuation. The projection growth is also capped at 15%. - DCF Value — the resulting fair value.
- Margin of Safety — positive means the price is below the DCF estimate; negative
means above.
Seeing the models side by side is the point: when they roughly agree, you have a more
robust read; when they diverge, that disagreement is itself information about how
uncertain the valuation is.
Step 5 — The fundamentals cards
Three compact cards round out the picture with the ratios analysts lean on. Every row
has an info tooltip with a one-line definition, so you can hover for a refresher.
- Valuation — P/E, Forward P/E, PEG (P/E adjusted for growth — below 1 can hint at
undervaluation), P/B, P/S, and Book Value. - Profitability — Profit Margin, Operating Margin, ROA, ROE, and EPS estimates for
the current and next year. - Dividends & Market — Dividend per Share, Dividend Yield, Beta (volatility vs the
market), the 52-week High and Low, and the average analyst target price.
These ratios are most meaningful in context — compared to a company's industry
peers and its own history — rather than read as absolutes.
"How to Read This Page" — the built-in primer
Near the bottom there's an expandable How to Read This Page section. It's worth
opening at least once: it explains intrinsic value, walks through Graham's formula and
the DCF in plain language, describes the gauge and the margin-of-safety concept, and —
importantly — spells out the models' limitations in the platform's own words.
The Value Leaderboard
When you first land on the page (before running a specific ticker), you'll see two
ranking tables:
- Most Undervalued — the stocks with the largest positive margin of safety.
- Most Overvalued — the largest negative margins.
Both are ranked by the Owner-Earnings Fair Value — the same DCF-weighted blend as
the primary gauge, so the rankings and the single-ticker page always agree — and
refreshed periodically. Only stocks where both core models (Graham's growth formula
and the DCF) produce valid values are included; the Graham Number refines the blend when
available. The margin is capped at ±100% to keep extreme data artifacts from dominating
the list. Click any row to jump straight into that ticker's full analysis.
On the Essential plan the leaderboard appears as a blurred preview behind an upgrade
prompt; Advanced and Professional plans see the full top-ten tables and can open
any ticker.
Where these models stop being reliable
The page is candid about this, and so are we. Graham's formula and DCF were built for
established, profitable companies with reasonably predictable earnings. They can
produce misleading results for:
- unprofitable companies,
- fast-growing tech stocks (whose value is mostly in far-future cash flows),
- cyclical businesses (whose current earnings mislead), and
- companies undergoing major structural change.
This is also why a stock can show "Insufficient data," or land near the ±100% cap on the
leaderboard. A clean-looking number is not the same as a reliable one — match the tool to
the kind of company you're looking at.
A quick workflow
- Type a ticker and analyze with the auto-estimated growth rate first.
- Re-run with a more conservative growth rate to see how sensitive the fair value is
to that single assumption — if a small change swings the verdict, treat the result with
extra caution. - Compare the lenses — the primary Owner-Earnings Fair Value against the three
secondary figures (Graham + DCF, all-three average, DCF only). Agreement is reassuring;
divergence flags uncertainty. - Check the margin of safety, remembering Graham's 25–30% cushion was the whole point.
- Cross-read the ratio cards against the company's peers and history.
- Sanity-check against the limitations — is this even the kind of company these models
handle well?
