Method and assumptions
Runway is a scenario estimate. Revenue collection timing, hiring, annual contracts and one-off expenses can make actual cash movement differ from this simple model.
Net burn = operating costs - cash revenue. Runway months = cash balance ÷ net burn when net burn is positive.
Common questions
What if revenue is higher than costs?
The model shows zero burn and an open-ended runway; keep monitoring working capital and collection timing.
Does this include fundraising?
Add only committed cash that is expected to arrive within the planning period.
