How to use this calculator
Enter your monthly expenses by category
Breaking down costs by category tells you where to cut first if you need to extend runway. Aggregate numbers hide the problem.
Check your three scenarios
The current trajectory tells you where you're heading. The optimistic and aggressive scenarios show what's possible if you act now.
Use the raise timing signal
The rule of thumb: start raising when you have 12 months of runway left. Close before you drop below 6. No investor wants to save a dying company.
