What is cash burn?

Cash burn refers to the rate at which a company spends its cash reserves or capital to fund operations, typically measured on a monthly basis. It is a critical metric for startups and businesses that are not yet profitable, as it indicates how long they can sustain operations before needing additional funding.

What are the key features of cash burn?

• Operational Spending: Includes all expenses required to keep the business running, such as salaries, rent, utilities, and marketing.
• Investment in Growth: May also cover costs associated with scaling the business, like product development, market expansion, and customer acquisition.
• Negative Cash Flow: Cash burn is often associated with companies that have a negative cash flow, meaning they are spending more cash than they are generating from operations.

What are the components of Cash Burn:

• Gross Burn: The total amount of cash spent on operating expenses over a given period.
• Net Burn: The total cash outflow minus the cash inflow from operations. It represents the actual decrease in cash reserves.

How to Calculate Cash Burn:

1. Determine Gross Burn: Sum up all operating expenses for the period. Gross Burn=Total Operating Expenses
2. Determine Net Burn: Subtract any operating revenue from the gross burn. Net Burn=Gross Burn−Operating Revenue
3. Calculate Monthly Burn Rate: Divide the net burn by the number of months in the period. Monthly Burn Rate=(Net Burn/Number of Months)

What is an Example Calculation of Cash Burn? 

1. Gross Burn: If a company spends $500,000 on operating expenses in a quarter (3 months), the gross burn is: Gross Burn=$500,000
2. Net Burn: If the company generates $150,000 in operating revenue during the same period, the net burn is: Net Burn=$500,000−$150,000=$350,000
3. Monthly Burn Rate: Monthly Burn Rate=($350,000/3)=$116,667

What are the benefits of calculating Cash Burn?

• Financial Health Indicator: Helps assess the sustainability of a company’s operations and its financial health.
• Investor Insight: Provides investors with critical information about how efficiently a company is using its capital and how long it can operate before needing additional funding.
• Budgeting and Planning: Assists in creating more accurate budgets and financial plans, ensuring the company can manage its resources effectively.

What to consider when analyzing Cash Burn?

• Runway Calculation: Knowing the cash burn rate is essential for calculating the company's runway, or how many months it can continue to operate before depleting its cash reserves.
• Cost Management: High cash burn rates necessitate stringent cost management and efficiency improvements to extend the operational runway.
• Funding Needs: Companies with high burn rates need to plan for additional funding rounds to avoid running out of cash.
