Runway and Burn Rate Calculator
The Runway and Burn Rate Calculator identifies the moment you start sustaining your mission.
If profitability is about efficiency, runway is about strategy. This tool helps you move beyond day-to-day survival to ensure your business has the "airtime" required to reach its next major milestone, whether that is a funding round, a pivot, or full self-sustainability.
The Analysis Framework
This analysis helps you bridge the gap between your current cash reserves and your future growth targets. It calculates your "financial oxygen"—the point where you balance your monthly spending with the time remaining to achieve your long-term goals.
The Core Components
To find your "survival window," the calculator analyzes five specific metrics:
Monthly Revenue: The total income flowing into the business each month.
Monthly Fixed Costs: Your "rent"—the expenses that remain the same regardless of how much you sell.
Variable Cost (%): The cost that scales with your sales (materials, commissions, or delivery).
Cash on Hand: Your total liquid capital available right now.
Runway Goal: The specific number of months you want to ensure the business can survive without additional external capital.
What the Calculator Reveals
By inputting these figures, the calculator provides three critical insights:
Monthly Net Burn / (Profit): Your "fuel consumption." It shows whether you are consuming cash each month or adding to your reserves.
Net Runway (Months): Your "ticking clock." This is the exact number of months remaining before your cash balance hits zero at your current spending rate.
Required Capital: The "funding gap." This reveals the specific dollar amount you need to secure—either through new revenue or investment—to safely reach your Runway Goal.
Pro Tip: Extending your runway isn't always about raising more money; it’s often about "trimming the wick." Reducing your monthly fixed costs by even a small margin can add months of strategic breathing room to your business's life.
