What does burn rate mean in tech and startups?

Burn rate is the monthly or periodic rate at which a company spends its available cash. It is calculated by dividing total operating expenses by the time period. For example, if a company spends 150,000 dollars per month, its monthly burn rate is 150,000 dollars. This metric is critical for startups because it determines runway—how long the company can survive before needing new funding or achieving profitability.

How do you calculate burn rate?

To calculate monthly burn rate, divide your total monthly expenses by one month. For example: Total expenses = 200,000 dollars; Monthly burn rate = 200,000 dollars. To find runway, divide your total available cash by your monthly burn rate. Example: Available cash = 1,000,000 dollars; Monthly burn rate = 100,000 dollars; Runway = 10 months.

Why is burn rate important in tech companies?

Burn rate is important because it shows how sustainable a company is. Investors use burn rate to assess risk and determine whether a company needs to raise funding soon. Founders and managers use it to plan expenses and set financial targets. A high burn rate without corresponding revenue growth signals financial trouble, while a controlled burn rate with strong growth metrics indicates healthy business operations.

Is a high or low burn rate better?

Neither is universally better; it depends on context. A high burn rate with strong revenue growth and market expansion may be acceptable. A low burn rate with stagnant growth indicates inefficient use of capital. The ideal burn rate is one that balances spending for growth with financial sustainability and available runway.

Don't say this

Handle with care. Often confused with 'cash burn' or used too broadly; specifically refers to the speed at which money is spent, not general progress or failure.

✕Our burn rate is very fast.

✓Our burn rate is high or Our burn rate is accelerating.— Burn rate is measured in money per time period (e.g., dollars per month), not in speed. Use 'high' or 'accelerating' instead.

✕We burned the rate last month.

✓Our burn rate was 120,000 dollars last month or We burned through 120,000 dollars last month.— Burn rate is a noun representing a metric, not an action. Use 'burned through' or describe the rate itself.

✕We need to burn rate faster to grow.

✓We need to spend more strategically to accelerate growth or We are increasing our burn rate to invest in product development.— Burning rate faster is not a strategic goal; explain what you are actually doing or investing in.
