Burn rate is the speed at which a company spends its cash reserves before generating positive cash flow from operations. It is the single most important metric for startup survival.
Runway (months) = Cash on Hand / Net Burn Rate
Runway tells you how many months your company can survive at the current burn rate before running out of cash. Most investors want to see at least 12-18 months of runway after a funding round.
Common strategies include renegotiating vendor contracts, reducing headcount or hiring freezes, cutting marketing spend on low-ROI channels, switching to more affordable tools, and subletting unused office space. Focus on cuts that do not directly impact revenue generation.
If your runway drops below 6 months, treat it as an emergency. Fundraising typically takes 3-6 months, so waiting until you have only 3 months left puts you in a desperate negotiating position. Track burn rate weekly, not monthly, when runway is short.
