What changes this most?
Runway improves by increasing inflow, reducing outflow or adding cash; model those separately.
Sensitivity check
A roughly 10% move in monthly cash outflow changes the modeled headline result by up to 2 months in this setup.
Runway is sensitive to timing, working capital and one-off costs.

Formula
Runway months equal available cash ÷ monthly net burn when monthly cash outflow exceeds inflow.
Uses constant monthly inflow and outflow. It does not model timing differences, financing availability, taxes or working-capital shocks.
Editable rates, growth assumptions, prices, fees, and percentages are planning inputs unless the calculator explicitly identifies a current source.
