Live data, not blank forms
Search any US-listed stock and the tool auto-populates with real free cash flow, shares outstanding, and current price from Yahoo Finance. You adjust; the tool does the math.
Teaches while you model
Every input has a contextual explanation. Every assumption triggers a warning if it's unrealistic. You learn what a good discount rate is by seeing why a bad one changes the answer.
Designed for conviction, not false precision
No tool gives you a single "correct" intrinsic value. Each tool shows a range — sensitivity tables, scenario comparisons, bull/bear/base cases. Robust theses hold across a range of assumptions.
Shareable results
Every valuation produces a unique URL with a custom preview card. Share your Apple DCF analysis on Twitter and the link shows exactly what you found — company name, intrinsic value, upside.

What is a DCF calculator?
A DCF (discounted cash flow) calculator estimates what a business is worth today based on the cash it will generate in the future. You project free cash flows, discount them to present value, and compare the result to the current stock price.
What does the Earnings Quality Score measure?
The Earnings Quality Score grades a company's reported earnings on 5 dimensions: FCF-to-net-income coverage, accruals ratio, accounts receivable growth vs. revenue, gross margin stability, and capex vs. depreciation. A high score means earnings are cash-backed and reliable.
What is ROIC and why does it matter?
Return on Invested Capital (ROIC) measures how efficiently a company generates profit from its capital. ROIC above WACC (cost of capital) means the company creates value. ROIC below WACC means it destroys value — even if earnings per share are growing.
