Understanding Runway
Runway is the number of months your business can operate before running out of cash. It's calculated by simulating your cash balance month by month, accounting for expenses and growing revenue.
Revenue growth models how quickly your income increases each month. A new restaurant might grow 5–10% monthly in year one; a service business with referrals might grow 15–20%.
Rule of thumb: Most advisors recommend having at least 6–12 months of runway before launching. The what-if scenarios help you find the right balance between investment and risk.
