Burn Rate Calculator
In the fast-paced world of startups and entrepreneurship, knowing your burn rate is absolutely essential. It tells you how quickly your business is spending its cash and how long you can survive at your current spending level without new revenue or funding.
The Burn Rate Calculator helps you instantly estimate how many months of runway you have left by dividing your total cash reserves by your monthly expenses. This simple yet powerful metric can mean the difference between scaling smart and burning out.
Formula
The burn rate is calculated using the following formula:
Burn Rate (Months) = Total Cash ÷ Monthly Operating Expenses
Where:
- Total Cash is the current amount of cash or cash equivalents your business has.
- Monthly Operating Expenses include payroll, rent, utilities, marketing, software, and all regular costs to keep the business running.
How to Use the Calculator
- Enter Total Cash:
This is the amount of liquid cash you currently have available. - Enter Monthly Operating Expenses:
Input the total amount you typically spend each month. - Click "Calculate":
The result will show how many months you can continue operating at your current rate.
Example
Let’s say your company has:
- $120,000 in total available cash
- $20,000 in monthly operating expenses
Using the formula:
Burn Rate = 120,000 ÷ 20,000 = 6 months
This means you have six months of runway remaining before you run out of cash, assuming no new revenue or changes in expenses.
Why Burn Rate Matters
- Investor Reporting: Investors want to know how much time you have left before needing more funding.
- Financial Planning: Helps you avoid surprises and plan for potential cutbacks or new capital injections.
- Startup Strategy: Determines how aggressively you can invest in growth or if you need to pivot.
- Sustainability: Keeps founders aware of financial health and spending habits.
FAQs
1. What is burn rate?
Burn rate is the rate at which a company spends its cash reserves every month.
2. What is a good burn rate?
It depends on the company’s stage and goals, but typically having at least 12–18 months of runway is considered healthy.
3. Is burn rate the same as cash flow?
No. Burn rate specifically focuses on cash outflows, whereas cash flow includes both inflows and outflows.
4. Can burn rate be negative?
Yes, a negative burn rate means you are cash flow positive — you're generating more than you spend.
5. How often should I check my burn rate?
Monthly reviews are ideal, especially in high-growth or high-risk environments.
6. What happens if my burn rate is too high?
You may run out of cash quickly, requiring emergency funding or operational cutbacks.

It typically includes ongoing monthly expenses. Separate one-time costs can be tracked independently.
