Burn rate is a financial metric that measures the rate at which a company expends its cash reserves to cover operating expenses. This metric is particularly important for startups, which often do not generate sufficient cash flow in the initial stages to fully offset their expenses. Burn rate is typically expressed in monthly terms and serves as an indicator of how long a company can sustain its operations before requiring additional funding.
Types of Burn Rate
Gross Burn Rate
Gross burn rate is the total amount of cash a company spends each month. It includes all operating costs such as salaries, rent, utilities, marketing expenses, and other overheads.
Net Burn Rate
Net burn rate subtracts the company’s monthly revenue from its monthly expenditures. This gives a more accurate picture of how quickly a company is depleting its cash reserves.
Runway
Runway refers to the amount of time a company can continue to operate at its current burn rate before its cash reserves are exhausted. It is calculated by dividing the current cash reserves by the net burn rate.

Special Considerations
Startups must closely monitor their burn rate to ensure they have sufficient runway to reach key milestones, such as product launches or securing additional investment. A high burn rate can indicate financial mismanagement or an unsustainable business model, while a low burn rate may suggest a conservative or highly efficient operation.
Examples
- High Burn Rate Example: A tech startup spends $150,000 per month with monthly revenue of $50,000. The net burn rate is $100,000, and with $500,000 in reserve, the runway is five months.
- Low Burn Rate Example: A consulting firm spends $30,000 monthly with revenue of $25,000, yielding a net burn rate of $5,000. With $150,000 in reserve, the runway is 30 months.
Historical Context
Burn rate as a concept gained prominence during the dot-com bubble in the late 1990s, when numerous internet startups burned through investor capital at unsustainable rates. This led to a heightened awareness of the importance of careful financial management and planning in entrepreneurial ventures.
Applicability
Startups
Burn rate is critical for startups to ensure they manage their expenses and secure additional funding before running out of cash.
Investors
Investors use burn rate to evaluate the financial health and sustainability of potential investments.
Comparisons

- Gross Burn Rate vs. Net Burn Rate: Gross burn rate reflects total expenses, while net burn rate accounts for revenue, offering a clearer picture of financial health.
