DCF: 10-year forecast of free cash flow, discounted at the company's WACC, with a Gordon-growth terminal at year 10. FCF is proxied by last fiscal-year net income (proper FCF needs CFO − CapEx by year, which we don't store yet). Drag the slider to test your own growth thesis — the dominant assumption in any DCF is what comes next, not what the math does with it. Beta defaults to 1.0 when not reported.

Solid: this company. Dotted: industry median.
Dashed flat: own 5y avg.
Coloured dot at right: current P/E.

P/E uses year-end weekly close ÷ (net income ÷ shares outstanding today). Held shares constant at today's count, which understates the per-share earnings improvement from buybacks over the period. PEG uses 5y revenue CAGR as a proxy for EPS growth — close, but not identical (margin expansion or dilution can drive a wedge). Best read as a comparator across companies and industries, not as a precise replica of historical multiples.
