What Is the Zero Cash Date Net Burn Framework?

Objective: Forecast the exact calendar month when liquid cash reserves hit zero by incorporating collected MRR growth curves and headcount cohorts.

  1. Step 1: Calculate True Net Monthly Burn: Subtract verified collected cash receipts from gross monthly operating expenditures.
  2. Step 2: Layer Revenue Growth Rate: Apply trailing 3-month compounded MRR growth percentage to project future net burn shrinkage.
  3. Step 3: Determine Zero Cash Date: Model month-by-month cash balances until cumulative net burn exhausts cash reserves.
  4. Step 4: Establish 18-Month Capital Buffer: Benchmark runway against institutional milestones to initiate financing 6 months before runway breaches 12 months.
