How runway is calculated

Net burn: monthly expenses minus monthly revenue. If expenses exceed revenue, you are burning cash.
Runway: cash on hand divided by monthly net burn. The result is the number of months before your cash reaches zero.
Cash-flow positive: if revenue covers all expenses, net burn is zero or negative and runway is unlimited.
