Cash ÷ monthly burn, plain division — no revenue or growth adjustment. Defaults ($500k ÷ $50k) give 10.0 months; the bar scales to 60 months with green above 18, amber above 6, red at or below 6. Three presets: Seed, Series A, Bootstrapped.
12+ months: operate; 6–12: plan (raise/cut/grow); under 6: emergency mode. Founders consistently act two quarters late.
