Operating Cash Buffer

Definition

The minimum cash reserve a business holds to cover normal operating expenses through unexpected disruption — typically expressed in weeks of fixed operating expenses (rent, payroll, software, insurance).

Why it matters

Without an explicit buffer target, owners discover too late that 'comfortable' cash levels are actually thin. A defined buffer (commonly 8–12 weeks for service businesses, 12–16 for project-based) becomes the anchor for cash flow forecasting decisions: bonus timing, capital purchases, hiring decisions, and distribution policy all reference it.
