Cash Burn Ratio Calculator
Cash flow is the lifeline of any business, especially for startups and companies operating with limited external funding. The Cash Burn Ratio is a critical metric that indicates how long a business can continue its operations with its current cash reserves, given its monthly expenses.
Knowing this figure is essential for financial planning, risk management, and investor relations. The Cash Burn Ratio Calculator offers a quick and simple way to estimate how many months your cash will last, providing a clear window into your operational runway and financial health.
Whether you're preparing for a funding round, managing a downturn, or tracking your financial stability, this tool is indispensable.
Formula
The formula for calculating the cash burn ratio is:
Cash Burn Ratio = Total Cash Available / Monthly Operating Expenses
The result tells you how many months your business can continue operating without generating additional revenue or receiving new funding.
How to Use the Cash Burn Ratio Calculator
- Enter Total Cash Available – This is the total liquid cash your company currently holds in accounts.
- Enter Monthly Operating Expenses – This includes recurring expenses such as rent, payroll, utilities, and other monthly outflows.
- Click Calculate – The result will show how many months your cash will last.
This simple method provides valuable foresight and helps prioritize strategic actions based on available capital.
Example
Assume your company has $250,000 in cash and your monthly operating expenses are $50,000.
Using the formula:
Cash Burn Ratio = 250,000 / 50,000 = 5
This means you have five months of operational runway before cash reserves run dry, assuming expenses stay the same and no new income is received.
