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

I 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 I 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 I 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 I understand the mechanics — projecting free cash flow, discounting it, where terminal value comes from — not just how to fill a template.
