Your assumptions. Institutional machinery.

What it tells you

Every serious investor eventually disagrees with every model — that's what makes them serious. The DCF Calculator hands you the controls: set your own cash-flow trajectory, capital-spending path, and discount rate, and the engine computes the implied fair value with the same rigor and transparency as the built-in scenarios. It turns "I think the market's wrong about this one" from a feeling into a number you can defend.

Who it's for

For the investor whose edge is a differentiated view — and who wants to quantify it.

How it works

• Every input arrives pre-filled with the engine's own values — Year 1 operating cash flow, Year 1 capital expenditure, growth rates for years 2–5, WACC, and terminal growth — with the engine default shown beneath each numeric field, so you always see exactly what you're overriding.
• Your scenario is computed server-side in the same codebase as the engine — verified to reproduce the engine's base case to within a fraction of a cent on standard valuations — not a client-side spreadsheet re-implementation.
• Inputs are guard-railed and validated on the server (WACC 3–25%, terminal growth −2% to 6%, WACC at least 1 point above terminal growth), preventing mathematically unstable outputs.
• The result is labeled "User-generated valuation" under your own scenario name and compared against the engine's model value, with a full year-by-year projection table and equity bridge — and one click resets everything to engine defaults.
