Cash on hand

Liquid cash available for operations.

Average monthly burn

Net cash outflow per month (positive number).

Runway (months) —

Cash 240,000 with burn 30,000/month → about 8.0 months of runway.

Runway ≈ cash on hand ÷ monthly burn when burn is steady and positive.

Use the net figure that matches how you fund the gap each month.

If burn is already net of inflows, you are set; otherwise recompute net burn.
