Cash Flow Runway Calculator: Instantly Know How Long Your Startup’s Cash Will Last

Every founder, finance lead, or investor knows—cash flow runway is a make-or-break number. With this effortless Cash Flow Runway Calculator, you get immediate, actionable insight into how many months your cash will sustain your business, helping you plan smarter and act sooner.

What Is a Cash Flow Runway Calculator?

A Cash Flow Runway Calculator tells you exactly how long your company’s current cash reserves will last based on your monthly expenses and recurring revenue. It empowers you to:

• Forecast burn rate: See at-a-glance how quickly funds are depleting.
• Plan hiring, fundraising, and cost control with real numbers, not guesswork.
• Avoid sudden cash crises by anticipating when you’ll need new capital.

Formula:
Runway (months) = Current Cash Balance / (Monthly Cash Expenses – Monthly Recurring Revenue)

If your revenue meets or exceeds expenses, your runway is effectively unlimited and you’re cash flow positive.
