About Burn Rate & Runway

Burn rate is how quickly a company spends money. Gross burn is total monthly expenses, while net burn accounts for revenue (expenses minus income).

Runway is how long you can operate before running out of cash, calculated as:

Runway (months) = Cash Balance ÷ Net Monthly Burn

Ideal Runway Benchmarks

  • 18+ months: Healthy position, time to focus on growth
  • 12-18 months: Start planning next funding round
  • 6-12 months: Actively fundraise or cut costs
  • <6 months: Critical — immediate action needed

Tips to Extend Runway

  1. Reduce burn: Cut non-essential expenses, renegotiate contracts
  2. Increase revenue: Focus on monetization and customer acquisition
  3. Raise capital: Start fundraising before you need it (12-18 months runway)
  4. Explore alternatives: Revenue-based financing, grants, or strategic partnerships
