How is startup runway calculated?

Runway is how many months your startup can operate before it runs out of cash. The formula is cash ÷ net monthly burn, where net burn is your monthly expenses minus monthly revenue. If you make more than you spend, you're default alive and your runway is effectively unlimited (∞).
