Frequently Asked Questions
How do I calculate my startup runway?+
Runway (months) = Cash on hand ÷ Monthly burn rate. Monthly burn rate = Monthly expenses − Monthly revenue. If you have $100k saved, spend $15k/month, and earn $5k/month, your burn rate is $10k/month and your runway is 10 months.
What is a healthy runway for a startup?+
Aim for 12-18 months of runway minimum. 6 months is dangerously short — one bad month and you're done. 24+ months gives you breathing room to iterate and find product-market fit. Always add a 20% buffer because expenses are always higher than expected.
How do I extend my runway?+
Three levers: (1) Cut fixed costs — renegotiate contracts, switch tools, reduce team. (2) Increase revenue — raise prices, add services, improve conversion. (3) Raise capital — investors, loans, grants. Cutting costs is fastest but has limits. Revenue growth compounds.
