Frequently Asked Questions
- How is burn rate calculated?
- Monthly burn rate = monthly expenses - monthly revenue. Positive burn rate means you're spending more than you earn.
- What is a healthy runway?
- 18-24 months is ideal. 12-18 months is manageable. Under 6 months is critical — start fundraising or cutting costs immediately.
- How do growth rates affect runway?
- Revenue growth extends runway; expense growth shortens it. Even small monthly growth rates compound significantly over 12+ months.
