Startup Runway Guide
What Is Runway?
Runway shows how many months your company can sustain operations with current cash and burn rate. Investors typically want to see at least 18 months of runway.
What Is Burn Rate?
Gross burn rate: Total monthly expenses. Net burn rate: Expenses - Revenue = monthly cash decrease. When revenue exceeds expenses, net burn is negative and cash grows.
Runway Extension Tips
- Postpone or cut non-essential expenses.
- Focus on revenue growth strategies.
- Start fundraising before cash drops below 6 months.
- Track monthly cash meticulously.
Info
For early-stage startups, 12-18 months is ideal. If planning a fundraise, start preparation at least 6 months before — so 18+ months runway is recommended.
First cut unnecessary expenses. Then look for quick wins on revenue growth. In parallel, evaluate fundraising or bridge financing options. Take action before dropping below 3 months.
Net burn rate is more realistic as it accounts for revenue. However, if revenue projections are uncertain, calculating conservatively with gross burn rate is safer.
