What Runway Means, and When to Fundraise
Runway is the number of months your company can keep operating before cash reaches zero, assuming revenue and expenses stay on the current path.
The standard formula is simple: cash in bank divided by monthly net burn. Net burn equals monthly expenses minus monthly revenue.
If your runway drops below 12 months, it is usually time to start preparing a fundraising process, even if you do not need capital immediately.
