01 · The opportunity

What it set out to solve

Any business needs defensible numbers for valuation and profitability, not gut feel, and the intuition is usually buried inside spreadsheet cells nobody opens.

02 · The approach

How I thought about it

We apply security analysis and valuation to a real business case: a DCF and a COGS-driven P&L that tie every assumption to the output. Then we rebuild the DCF as an interactive tool so the intuition is visible, not hidden in cells.

03 · What I built

  • Discounted cash flow valuation model (Excel)
  • COGS and P&L model with scenario levers
  • MRP / invoice cross-check tooling
  • A live, interactive DCF calculator (below), change the assumptions, watch enterprise value move

04 · The result

What changed

Cleaner financial decisions grounded in transparent assumptions, and a demo that shows we understand what's inside the model, not just how to run one.

Live · interactive

Play with the assumptions.

Move the sliders and watch enterprise value respond. It's the same discounted-cash-flow logic as the Excel model, just made visible.

Enterprise value

74% of the value sits in the terminal value, most of a growth business is worth what happens after the forecast.

PV of forecast FCF

₹64 Cr

PV of terminal value

₹183 Cr

Free cash flowPresent value of FCF

Simplifying assumption: free cash flow ≈ NOPAT (depreciation ≈ capex, no working-capital swing). Enough to show the intuition, nudge WACC or growth and watch value move. A full model layers in those line items.

The questions I'd get asked about this, and my answers

Why build models in Excel/Sheets and not code?

The audience is finance leadership. A transparent model they can open and poke beats a black-box script. Excel is the right tool when the reader needs to see every assumption.

Then why also build the interactive version here?

To make the sensitivity obvious: nudge WACC and watch value swing. It proves we understand the mechanics, projecting free cash flow, discounting it, where terminal value comes from, not just how to fill a template.
