About Cash Runway
Cash Runway is the amount of time your company can operate before running out of money, based on your current cash balance and monthly burn rate.
Burn Rate = Monthly Expenses - Monthly Revenue. A positive burn means you're spending more than you're earning.
Why it matters: Understanding your runway is critical for planning fundraising, making strategic decisions, and ensuring business continuity. Most investors want to see at least 12-18 months of runway.
