What is Runway?
Cash in the bank divided by monthly net burn, which gives the number of months a startup can keep operating. Investors check it to see how soon the company must raise again or reach profit.
$1.8M ÷ $150K a month = 12 months
In real work
With $1.8 million in the bank and a net burn of $150,000 a month, the founders told investors they had 12 months of runway.
In the illustration
The tank's sight gauge stands at $1.8M and the metering tap's flow gauge settles at $150K a month. A month rule beside the glass divides the level into 12 equal marks down to empty, and the months-left dial stops at 12.
Calculate runway in your deal notebook from the bank balance and the last three months of spending and revenue below. Show the arithmetic, then show it again with net burn 20 percent higher.
