The matrix adjusts these base values across revenue and expense ranges.
Scenario ranges
Define how far revenue and expenses can move from the base case.
Founder tip
Try a wider range first, then narrow it to focus on realistic outcomes.

FAQs
What is a runway sensitivity matrix?
It shows how runway changes when revenue or expenses move up or down. It helps founders stress-test assumptions.
How should I pick revenue and expense ranges?
Use realistic variance based on your last few months. The matrix is most useful when ranges reflect plausible outcomes.
Why does CF+ appear?
CF+ means cash-flow positive. In those scenarios, revenue covers expenses so runway is effectively unlimited.
