The full model.
Not just a calculator.

The calculators give you directional answers. The Financial Clarity Model gives you the complete picture, 12-month P&L, cash flow with three scenarios, and unit economics, all formula-linked from one inputs tab.

  • 12-month projected P&L, revenue, COGS, OpEx, EBITDA
  • Cash flow with Base / Upside / Stress scenarios
  • Dynamic runway counter updated month-by-month
  • Hiring plan with loaded costs and runway impact
  • Unit economics, LTV, CAC, payback, health indicators
  • One inputs tab drives everything else

This model is a planning framework and does not constitute financial, accounting, or tax advice. Consult a licensed professional for those services.

Free. No spam. Occasional financial frameworks founders actually use.
