Read price, earnings and peer assumptions together. The calculator keeps accounting multiples, signed earnings yield and modeled share prices distinct, with explicit definitions and manual source notes.
Keep three arithmetic questions separate
A share price of $100 and annual earnings per share of $5 produce a P/E of 20×. Reversing the two inputs gives an accounting earnings yield of 5%. Neither number states how much cash the company will distribute or what return an investor will receive. A third calculation selects a multiple and multiplies it by annual EPS. An entered peer assumption of 10× therefore implies $50 for the same $5 EPS, while the original price remains $100. That modeled price is not an independently estimated intrinsic value.
Zero and loss earnings need different explanations. At EPS of zero, ordinary P/E is undefined. At EPS of −$5 and a positive $100 price, the calculator suppresses ordinary positive-earnings valuation bands while retaining signed earnings yield of −5%. Missing price does not prevent selected-multiple analysis, but it removes earnings yield and distance-from-price values. A zero entered price likewise cannot serve as the denominator of earnings yield. Review which question each result answers before comparing the numbers.
Match entered definitions before comparing peers
EPS is an entered accounting amount with a period and share basis. Trailing annual earnings and forward annual estimates answer different questions, and basic and diluted share counts can produce different per-share amounts. The explicit quarterly × 4 option simply repeats one quarter four times. It does not add four reported quarters, adjust seasonality or verify an annual forecast. Price dates, EPS period ends and source notes provide context without turning manual inputs into a live data feed.
The primary peer and up to three additional records can follow the selected earnings convention as an explicit user assumption, or carry their own definitions. A differently marked forward, share-basis or period record remains visible in the peer table but is not blended into a comparable multiple. A large finite peer is not silently discarded and no peer average is invented. Matching labels still do not prove that two businesses have comparable risk, leverage, accounting quality or future prospects. Use the separate records to document assumptions that require further investigation rather than treating the chart as a ranking of investment quality.
Inspect a multiple instead of trusting a verdict
The implied-price chart holds an earnings case fixed and varies the selected P/E multiple. With annual EPS of $5, a selected 12× multiple implies $60. Optional EPS cases of $4 and $6 imply $48 and $72 at that same multiple. Against a current price of $100, the central scenario is $40 lower, or −40% relative to the current price. These are transparent arithmetic scenarios, not estimated probabilities, price targets from a provider or claims that a security should trade at the selected multiple.
Inspect a plotted point or use the table to read the matching raw multiple and EPS cases. The current price is an independent reference line when provided. Missing price leaves implied-price analysis available; nonpositive EPS cases do not create ordinary positive-earnings bands. The separate price-sensitivity table asks the inverse question by varying price while keeping annual EPS fixed. Optional PEG, Graham Number and growth-plus-dividend references remain separately labeled heuristics. They do not validate the selected multiple, combine into an intrinsic-value model or replace analysis of debt, cash generation and accounting choices.
Keep scenario context in saved and shared results
Capture a set of entered assumptions before changing the current case. For example, save a trailing EPS case, switch to forward estimates, and enter a different EPS. The page retains both definitions rather than labeling the difference a matched valuation change. Captured inputs remain separate from the current controls, and an incomplete or malformed captured record does not acquire invented default financial values. Price date, earnings period and source notes should travel with each comparison so the numbers can be interpreted later.
Ordinary edits do not write financial inputs into a public URL or silently create a new device draft. Remember is a separate device-saving choice. Share first opens a clean-link preview; include the financial assumptions only after selecting that option and reviewing the result. Copy, CSV and Print use the active calculation and its explicit context. CSV retains raw numerical values, while visible currency and percentages can round independently. Previously saved optional blanks remain blank when restored. Reset returns the current authored defaults and clears only this calculator’s saved state; it does not remove other calculators’ drafts or verify any entered market information.
