IntroductionCash runway and gross burn rate are important financial metrics that every business leader should be aware of. Together, they tell you how long your company can survive on its current cash reserves and how much you're spending monthly to keep operations running. In this post, we’ll break down these concepts using a visual example and explain what they mean for your financial health.
What Is Cash Runway?Cash runway is the number of months your business can operate with its existing cash reserves and current spending rate. Think of it as how long your “fuel” will last before running out.
In the chart above, the blue line represents cash runway. Notice how it dips from February through July 2024 before sharply rising again toward October. The low point (2 months) in June and July signals a potential risk of running out of cash.
What Is Gross Burn Rate?Gross burn rate is your total monthly operating expenses, including cost of goods sold (COGS) and operating expenses (OPEX). It tells you how much cash your business “burns” every month to stay operational.
In the chart:
The red bars represent total COGS and OPEX, which vary from month to month.
The black line illustrates the average COGS and OPEX or, gross burn rate, which is significant relative to the cash available.
Why These Metrics Matter
Early Warning Signals: A declining cash runway can warn you as to potential cash flow risks, and can help you be appropriately proactive when it comes to securing funding, cutting costs, or boosting revenue.
Informed Decision-Making: Monitoring your gross burn rate helps you understand how much money is being spent each month and where there may be opportunities for improvement – either in terms of reducing expenses or increasing investments in the business.
Growth vs. Sustainability: While growth might mean temporary dips in cash reserves, it’s essential to plan a recovery period, like the sharp rise seen in August–October.
Key Insights from the Chart
March 2024: Cash runway improves to ~2.5 months, aligning with a peak in cash reserves (green bars).
June–July 2024: Cash runway is at its lowest (2 months). Without intervention, this could trigger cash flow issues.
October 2024: Cash runway jumps to 3 months, showing improved financial stability alongside higher cash reserves.
How to Improve Your Cash Runway and Burn Rate
Monitor Spending: Analyze OPEX and COGS to identify and cut unnecessary costs.
Boost Cash Reserves: Secure financing or improve accounts receivable collection.
Plan for Growth: Growth often burns cash initially—make sure you plan for that, and ensure you plan recovery phases to stabilize cash runway.
ConclusionUnderstanding cash runway and gross burn rate allows you to stay proactive and make smarter decisions for your business. By analyzing trends like the ones above, you can anticipate challenges, optimize spending, and ensure long-term sustainability.
