Burn rate is the rate at which a company spends its cash reserves, typically measured monthly. Gross burn rate is total monthly expenses. Net burn rate is expenses minus revenue — the true rate at which cash is being depleted.
Runway is the amount of time (in months) a company has before it runs out of cash, calculated as: Current Cash / Mensile Net Burn Rate. For example, with $500K in the bank and a $25K/month net burn, your runway is 20 months.
Most investors recommend 18–24 months of runway at any funding stage. Pre-seed startups should aim for 12–18 months, seed stage 18–24 months, and Series A+ 24–36 months. Less than 6 months is considered a crisis zone requiring immediate action.
You can extend runway by: reducing expenses (layoffs, vendor negotiations, cutting non-essential costs), increasing revenue (pricing changes, new customers, upsells), raising additional funding, or generating revenue faster than planned.
