Startup Burn Rate & Runway Simulator — 24-Month Cash Control | 3 Scenarios | Bilingual ES/EN

The Burn Rate & Runway Simulator is a professional-grade Excel financial model designed for startup founders, CFOs, and finance teams who need precise control over their cash position.

The model projects 24 months of cash flow — breaking down revenue, expenses by category, gross burn, and net burn — with a powerful three-scenario engine (Base, Bear, Bull) controlled by a single toggle cell. Change one number and the entire model, including runway, zero-cash date, and hiring plan, recalculates instantly.
