What is Cash Burn & How to Calculate It for Your Business

At what rate is your business burning cash and how to apply cash burn analysis to assess the survival period for your business.

Regular cash burn analysis allows to take action to ensure sustainability, while minimizing the risk of running out of cash. Cash burn rate is a common metric of performance and valuation for Companies and startups.

The cash burn rate is also a vital metric for investors, providing insights into a company's financial sustainability, growth potential, and overall risk profile.

Cash Burn Analysis for Better Cash Control

Cash burn analysis is a critical financial assessment to understand cash flow dynamics and measure the rate at which a business is spending cash. In simple terms, the cash burn-out rate represents the speed at which a company consumes its cash reserves, hence how quickly it "burns" its' cash.

By closely monitoring cash burn rates, entrepreneurs can identify trends, assess the sustainability of their current spending, and make informed decisions regarding budgeting and financial strategies.

This analysis enables to project how long a business can operate before needing funding, thus enhancing cash control and resource allocation.

How to Calculate Cash Burn Rate

Calculating the cash burn-out rate is pretty simple. Because It is an indication of how quickly a company is spending its available cash to cover operating expenses, it requires the following steps:

1. Determine Your Cash Position Day1: Identify the total cash available in your business bank accounts. For example, let's say you hold $10,000 on day 1.

2. Calculate Your Monthly Operating Expenses: Sum all monthly expenses, including salaries, rent, utilities, marketing, etc. Let's say your total expenses are $1,000 per month.

3. Calculate Your Cash Burn Rate using this formula:

   
   

Gross Cash Burn = Monthly Operating Expenses ($1,000)

The gross burn rate is more straightforward to calculate because it doesn’t factor in any incoming cash flows. It purely focuses on your cash outflows.

Assessing Survival Period

The cash burn survival period is most commonly measured as a monthly rate. To assess how long your business can survive with its current cash reserves, follow these steps:

1. Use Current Cash Reserves: Total cash available as calculated earlier.

2. Calculate Monthly Cash Burn: Use the cash burn rate calculated earlier.

3. Estimate Survival Period using this formula:

   
   

Survival Period(months) = Cash Reserves / Monthly Cash Burn

The crucial piece of information based on the earlier example, is that if your cash burn is $1,000 per month and you have $10,000 of cash reserves —assuming no funding, then your runway or survival period is 10 months. That’s the total amount of time you can run operations before you run out of cash. An investor will closely look at this metric.

How do Investors use the Cash Burn Rate

Investors use the cash burn rate as a critical metric to evaluate a company's financial health and sustainability. Here are some key ways investors utilize the cash burn rate:

• Assessing Financial Health

Investors analyze the cash burn rate to determine how quickly a company is using its cash reserves. A high burn rate may indicate that a company is spending aggressively, which can be risky if it does not have sufficient funding or revenue.

• Monitoring Growth Strategies

A company's burn rate can indicate how well it is executing its growth strategies. Investors look for a balanced approach where spending is aligned with revenue growth, ensuring that the company is not overextending itself.

Cash Burn Rate as a critical metric for investors.

• Risk Assessment

As part of the investor risk framework, investors can assess the risks associated with each investment. A company with a high burn rate and low revenue may face significant challenges, making it a riskier investment.

• Benchmarking Against Industry Standards

Investors often compare a company's burn rate to industry averages to gauge performance relative to competitors.

• Exit & Funding Consideration

Investors use the cash burn rate to decide whether to invest. If the burn rate is sustainable and aligns with projections, investors may be more inclined to fund. The cash burn rate can also influence an investor's exit strategy. Understanding how long a company can sustain its operations without additional funding can impact decisions on when to divest their stake.

What is Negative Burn Rate or Zero?

A negative or zero burn rate indicates that a company is not spending more cash than it is generating, which is often a sign of financial stability or profitability. A zero burn rate means that the business is breaking even, with income matching expenditures, while a negative burn rate suggests that the company is generating more cash than it is using, potentially allowing for reinvestment or savings.

This scenario is generally favorable, as it implies the company is managing its finances effectively and may have a sustainable business model, reducing the need for external funding or financial support.

Basic Forecast & Budget

The next step is to forecast cash burn rates. To do that you must begin to think about spending patterns and cost trends, project future expenses based on planned growth initiatives, and consider potential revenue streams.

This will allow to estimate how long cash reserves may last in the future.

 Cash burn analysis refers to how quickly cash reserves are used up.

Be conservative in your estimates to avoid overestimating revenue and setting unrealistic expectations. Carefully estimate your business expenses for the up coming years. By maintaining a close watch on the burn rate and adjusting forecasts as necessary, companies can make informed decisions about scaling operations, fundraising, and managing cash flow effectively. Key steps to build a simple cash flow forecast:

• Develop Projections: Create detailed forecasts based on market trends and growth opportunities. Early-on, use simple techniques, such as trend analysis or judgement, to project future.

• Understand Base Case Trajectory: Establish a baseline scenario reflecting expected business performance.

• Conduct Stress Testing: Simulate adverse scenarios to test your business model's resilience.

• Analyze Results: Understand key metrics from stress tests to identify vulnerabilities and opportunities.

• Guide Decisions: Use insights to inform resource allocation and strategic planning.
