What is Burn Rate?

Burn rate is a measure of how quickly a company is spending its capital, typically before it generates positive cash flow. It's a critical metric for startups and growing businesses to monitor their financial sustainability and estimate how long they can operate before needing additional funding.

Types of Burn Rate

  • Gross Burn Rate: The total amount of operating costs a company spends each month, regardless of revenue.
  • Net Burn Rate: The difference between cash out and cash in (expenses minus revenue), showing how much capital is being depleted each month.

Understanding Runway

Runway is the amount of time a company has before it runs out of money, assuming the current burn rate remains constant. It's calculated by dividing the remaining capital by the net burn rate.

Runway (months) = Available Capital ÷ Net Burn Rate

For example, if your company has $500,000 in the bank and is burning $50,000 per month (after accounting for any revenue), your runway is 10 months.

Why Burn Rate Matters

  • Financial Planning: Helps companies plan when they need to raise additional capital.
  • Investor Relations: Investors closely monitor burn rate to assess a company's financial discipline.
  • Strategic Decisions: Influences hiring, expansion, and other growth decisions.
  • Survival: For pre-revenue startups, managing burn rate is directly tied to company survival.

Strategies to Extend Runway

  • Reduce Operating Costs: Identify and cut non-essential expenses.
  • Optimize Pricing: Consider adjusting your pricing strategy to increase revenue.
  • Focus on High-ROI Activities: Prioritize initiatives that generate revenue quickly.
  • Consider Alternative Funding: Explore revenue-based financing, grants, or strategic partnerships.
  • Negotiate Better Terms: Renegotiate with vendors or consider deferred payment arrangements.

Frequently Asked Questions

Not necessarily. A high burn rate can be appropriate for companies in rapid growth phases, especially if they're building infrastructure, expanding market share, or developing technology that will lead to future profitability. However, it should be strategically planned and monitored closely in relation to available capital and future funding opportunities.

For most startups and growing businesses, calculating burn rate monthly is standard practice. However, companies with limited runway or volatile cash flow might benefit from weekly calculations. Regardless of frequency, it's important to regularly review this metric as part of your financial dashboard.

Most investors and financial advisors suggest maintaining at least 12-18 months of runway. This provides enough time to achieve significant milestones, demonstrate growth, and secure additional funding if needed. Less than 6 months is generally considered concerning and may require immediate attention.

Technically, burn rate should focus on recurring operational expenses. However, it's important to account for planned large non-recurring expenses separately in your financial planning. For comprehensive financial health monitoring, track both your regular burn rate and any anticipated one-time costs.

Service businesses typically have more predictable and consistent burn rates, often closely tied to headcount costs. Product companies, especially those developing hardware or complex software, may have more variable burn rates with R&D phases requiring significant investment before revenue generation. Product companies might also face inventory costs that service businesses don't.
