fair-value calculator // DCF · reverse DCF · GrahamFREE

What’s a stock actually worth?

Three classic estimates — a two-stage DCF, a reverse DCF, and the Graham number — computed from a company’s own SEC filings, with every assumption editableand every input shown. The opposite of a proprietary “fair value” you can’t check.

Estimates, not targets. The DCF treats free cash flow as cash flow to equity and divides by shares (the common retail shortcut — it skips net debt and a full WACC), so it’s a sanity-check, not a valuation opinion. All inputs are from MSFT’s SEC filings; change any assumption above and the numbers update live. Educational only — not investment advice.

A DCF is only as good as its assumptions — that’s exactly why every one here is yours to change. We treat free cash flow as cash flow to equity and divide by shares (the common retail shortcut; it skips net debt and a full WACC), so treat the output as a sanity-check range, not a valuation opinion.
