Startup Burn Rate Calculator — Runway & Cash Flow Tool

Calculate your monthly burn rate and exact runway in months. Know exactly when you need to fundraise or reach profitability — before it's too late.

Practical example: $500K raised, building product. For a pre-revenue seed scenario, enter the values that match your situation to get an instant cost estimate.

What's a healthy runway for a startup? 18-24 months is the recommended minimum runway at any stage. Fundraising takes 3-6 months, so you should start the process at 12+ months of runway. Series A companies typically want to show 18 months of runway post-raise.

Formula: netBurnRate = monthlyExpenses - monthlyRevenue | grossBurnRate = monthlyExpenses | runwayMonths = cashOnHand / netBurnRate | yearlyBurn = netBurnRate × 12
