What is cash burn and how do we calculate?

Answered by Amado Berg

Cash burn is a term commonly used in business and finance to describe the rate at which a company is spending its available cash. It is a measure of how quickly a company is depleting its cash reserves, or in other words, how fast it is “burning” through its cash.

Calculating the cash burn rate is relatively straightforward. It involves comparing the total cash balance from the prior month with the cash balance in the current month. By subtracting the current cash balance from the previous month's cash balance, you can determine the amount of cash that has been used up or “burned” during that time period.

Let me illustrate this with a personal experience. A few years ago, I started my own small craft brewery. As a new business, we had limited financial resources, and it was crucial for us to closely monitor our cash burn rate to ensure we could sustain our operations and meet our financial obligations.

At the end of each month, I would review our financial statements and calculate our cash burn rate. This involved comparing the cash balance at the end of the previous month with the cash balance at the end of the current month. For example, if we had $50,000 in cash at the end of January and $40,000 at the end of February, our cash burn rate for February would be $10,000.

It is important to note that the cash burn rate is not the same as the company's net loss or profit. Net loss or profit takes into account all the revenues and expenses incurred during a given period, including non-cash expenses such as depreciation and amortization. On the other hand, the cash burn rate focuses solely on the cash flow aspect of a company's operations.

Understanding the cash burn rate is essential for businesses, especially startups and companies operating in industries with long development cycles or high upfront costs. It helps management to assess the sustainability of the business, make informed financial decisions, and plan for future funding needs.

Here are a few key points to consider when calculating and interpreting the cash burn rate:

1. Frequency of measurement: The cash burn rate can be calculated monthly, quarterly, or even annually, depending on the specific needs of the business. However, for most startups or companies with limited cash reserves, a monthly calculation is more appropriate to closely monitor their cash position.

2. Cash inflows and outflows: It is important to consider both the cash inflows and outflows when calculating the cash burn rate. Cash inflows may include revenue from sales, investments, or loans, while cash outflows encompass expenses such as salaries, rent, utilities, and other operating costs.

3. Variations in cash burn rate: The cash burn rate may vary from month to month or quarter to quarter, depending on various factors such as seasonality, business cycles, or one-time expenses. It is important to analyze any significant deviations from the average cash burn rate and understand the reasons behind them.

4. Cash runway: The cash burn rate helps determine the company's cash runway, which is the estimated amount of time the business can sustain its operations based on its current cash reserves and burn rate. This is a crucial metric for startups and companies seeking funding, as it indicates how long they can survive before running out of cash.

Cash burn rate is a measure of how quickly a company is using up its available cash. By comparing the cash balance from the previous month to the current month, businesses can determine their cash burn rate. This metric is essential for financial planning, assessing sustainability, and making informed decisions. Regular monitoring of the cash burn rate allows businesses to identify potential cash flow issues and take necessary actions to ensure their financial stability and growth.
