Burn Rate Calculator

How It Works

The burn rate calculator determines how much money your organization spends over a chosen period of time and how long the remaining balance can sustain that pace. To use it, you simply need to enter your initial cash balance, final balance, and the time frame between them. The calculator then processes this data and instantly provides you with two key results: your average monthly burn rate and your cash runway. The latter represents how many months you can continue operating before you run out of money. 

You can set the duration in days, weeks, months, or years, depending on how you track financial performance. The tool will adapt the output accordingly. This makes it easier to analyze both short-term projects and long-term ones. As a result, the monthly burn rate calculator gives you a clear picture of how your resources are being used, so you can monitor spending habits and forecast future costs. 

Formula

The cash burn calculator uses two related formulas:

Where:

• Initial Balance is your company’s funds at the start of the chosen period
• Final Balance is the amount left at the end of that period
• Duration is how long the period lasted (days, weeks, months, or years)
• Burn Rate is your average monthly spending
• Cash Runway is the number of months you can sustain operations at the current burn. rate

This method assumes you will continue spending at the same pace. Subtracting “1” represents the fact that one full period has already passed. 

Example

Let’s say your startup began with $100000 and ended with $70000 after three months. 

Burn Rate → (100000 – 70000) ÷ 3 = 10000

As you can see, your monthly burn rate is $10000.

Cash Runway → (100000 ÷ 10000) – 1 = 9

That means your business can continue operating for about nine months before running out of funds, assuming expenses stay consistent. 

This projection helps you understand your financial forecast and decide whether to reduce spending or plan your next funding round.
