Startup Burn Rate & Runway Calculator
"Estimate how many months your startup can operate before running out of cash, and plan your next funding round smartly."
Every founder needs to know their runway, the number of months before the company runs out of money. This free startup burn rate calculator helps you determine your monthly cash burn and operational runway based on expenses, revenue, and total cash on hand. Perfect for startups, SaaS founders, and financial managers planning for sustainable growth or preparing for investor pitches.
Ready to Analyze Your Burn Rate
Enter your startup's financial data on the left to calculate your burn rate and runway.
Burn rate is the rate at which a startup spends its available cash. It indicates how long the business can continue operating before depleting its funds.
How to Calculate Runway
Runway = Cash Balance ÷ Monthly Net Burn Rate
Why Runway Matters
A longer runway gives startups flexibility to iterate, test, and grow without rushing to raise additional funds.
A startup with $120,000 in cash, $30,000 in expenses, and $10,000 in monthly revenue has a net burn of $20,000 → Runway = 6 months.
Key Takeaway
Extending your runway by even 3 months can significantly improve investor confidence and negotiation leverage.
Pro Tip
Always monitor your burn rate weekly and have contingency plans for extending runway when needed.
