What is Burn Rate?
Burn rate refers to the speed at which a business spends its available cash to cover operational costs. It is generally calculated on a monthly basis and is used to evaluate a company’s financial performance. Burn rate helps determine how long a company can continue operating before it needs new funding or increased revenue. Startups often rely on burn rate tracking to manage their cash runway and avoid running out of funds.

Why do we use it?
Burn rate helps organisations understand their cash flow situation and overall financial sustainability. It plays a critical role in financial planning, budgeting, and investment decisions. Regularly monitoring burn rate allows businesses to provide transparency to investors and stakeholders while ensuring they have sufficient resources to grow.
How to Calculate a Burn Rate?
- Identify the total cash available at the beginning of the period
- Determine the remaining cash balance at the end of the same period
- Subtract the ending balance from the starting balance to calculate total cash spent
- Define the time frame for the calculation, such as monthly or quarterly
- Divide the total cash spent by the number of months in the selected period to find the average monthly burn rate
- Estimate the remaining cash runway by dividing current cash reserves by the monthly burn rate
Burn Rate Formula:
Burn Rate = Starting Cash−Ending Cash ÷ Number of Months
