How runway is forecast
Each month applies the selected growth rate to revenue and expenses, then adds revenue − expenses to cash. Runway is the first month ending at or below zero.
The target-runway thresholds use today's revenue and expenses as a simple immediate-action benchmark; the detailed forecast incorporates growth.
