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.
Adjust one assumption at a time to understand which inputs have the greatest effect. Compare several realistic scenarios rather than relying on a single projection.
Default assumptions are maintained by FinTrex and may not reflect current products or rates available to you. Review every input before using the estimate.
