Net cash burn rate

What Is Net Cash Burn Rate?

Net cash burn rate represents the speed at which a company consumes its cash reserves when its outflows exceed its inflows, particularly before achieving profitability. It is a key [financial metrics] that indicates the monthly net negative cash flow of a business, reflecting how much money a company is losing (or gaining) each month after accounting for both its expenses and its generated revenue. This metric is especially critical for startups and growth-stage companies that may not yet be generating sufficient income to cover their full operating expenses. Monitoring the net cash burn rate provides crucial insight into a company's financial health and its ability to sustain operations over time.83, 84, 85, 86, 87

History and Origin

While the concept of monitoring cash expenditure has always been fundamental to business, the term "cash burn rate" gained prominence with the rise of technology startups and the venture capital industry, particularly during the late 20th century. In the early days of these capital-intensive companies, especially those focused on rapid growth without immediate profitability, the rate at which they spent their invested capital became a critical measure of their viability and survival. The dot-com bubble of the late 1990s and early 2000s highlighted the dramatic consequences of excessive cash burn without a clear path to sustainable revenue. During this period, numerous internet companies with high spending and insufficient income ultimately failed when their cash reserves were exhausted, a phenomenon widely reported at the time.81, 82 For instance, a New York Times article from March 2000 highlighted the struggles of dot-com companies running out of cash, emphasizing the urgent need for either fresh capital or a path to profitability.80 This era underscored the importance of distinguishing between gross spending and actual net losses, solidifying the net cash burn rate as a vital metric for both entrepreneurs and investors.

Formula and Calculation

The net cash burn rate provides a comprehensive view of a company's cash consumption by accounting for both cash outflows (expenses) and cash inflows (revenue).67

There are two common ways to calculate net cash burn rate, typically on a monthly basis:

  1. Using Revenue and Expenses: This method directly subtracts monthly revenue from the total monthly cash expenses.

    Net Cash Burn Rate=(Total Monthly Operating Expenses+Non-Operating Expenses)Total Monthly Revenue\text{Net Cash Burn Rate} = (\text{Total Monthly Operating Expenses} + \text{Non-Operating Expenses}) - \text{Total Monthly Revenue}

    Alternatively, it can be calculated using the gross burn rate:

    Net Cash Burn Rate=Gross Cash Burn RateTotal Monthly Revenue\text{Net Cash Burn Rate} = \text{Gross Cash Burn Rate} - \text{Total Monthly Revenue}

    Where:

    • Gross Cash Burn Rate: Represents the total monthly cash outflow on operating expenses and other costs before considering revenue.64, 65, 66
    • Total Monthly Revenue: All cash inflows from sales, services, interest income, and other sources.63
