This calculator uses estimates. RunwayCal uses your real numbers. Connect your tools and see your actual runway.
Start FreeRunway is how many months your business can operate before running out of cash. It is one of the most important numbers for any business owner, but most people only calculate it once and never update it. Your runway changes every time you hire, lose a client, or cut costs.
Scenario planning lets you answer the questions that keep business owners up at night. What happens if we hire two people? What if our biggest client leaves? What if we cut software spend by 20%? Seeing the impact on your runway before you make the decision is worth more than any spreadsheet.
RunwayCal calculates your actual runway from real data, not estimates. Connect your bank, payroll, and revenue sources to see your true cash position, track how scenarios play out over time, and get alerts when your runway drops below your threshold.
