Level up your runway forecast
Knowing your burn rate is essential to running a startup. Learn how below, and get access to Causal's model to calculate it like the world's best-run finance teams do.
One key measure of a successful business is cash flow. If you're an investor-funded company, you'll want to be focused on reducing your burn rate. Reducing the size of your workforce or cutting wages are not the only strategies to achieve this. For example, proactively managing spending with tools that provide real-time visibility can help businesses avoid reactive measures like layoffs or pay cuts.

What is burn rate?
Startup companies with positive cash flow during their early stages are relatively rare. They self-fund or seek venture capital, develop a product or service, and then build a sales pipeline. Generating cash from sales comes last. A solid base of initial funding increases the runway to build, but at some point any new company must create cash flow to sustain itself.
Burn rate is the rate at which a business is “burning” their venture capital. An example of this is the development costs of building an online platform. The business isn’t generating any cash while the engineers are coding. The business is spending the amount of cash they have at a certain pace, and the pace of that spending is the burn rate.
Beginning to generate cash doesn’t eliminate the company's burn rate. To achieve positive cash flow, a business needs to bring in more cash than it's spending. That’s known as “cash flow positive.” Until you reach that point, you’re still burning some amount of money, albeit at a slower pace as sales increase. This is a critical metric to track for all businesses, not just startups or small businesses.
Why is knowing your burn rate important?
Tracking your burn rate should be part of the financial planning and analysis of your company. It’s not a line item on your financial reports, but it can be calculated using the cash flow statements from those reports. We’ll explain in further detail below.
The need for positive cash flow should be obvious, but many venture funded businesses wait too long to generate cash flow and reduce burn rate.
Business owners sometimes assume that they can simply raise an additional round of funding to cover new costs if they’re making progress on the development side. This is a mistake for several reasons:
Funding could dry up
Venture capitalist funds have other prospects. During fundraising, you’re going to compete with other businesses that are paying attention to their financial statements, current cash flow, and burn rate, and can prove their ability to be profitable. Keeping your own burn rate low increases your chances of getting additional funding if you need it.
Markets could go downhill
When capital becomes more expensive, or funds become more cautious during market downturns, reducing your burn rate can help lengthen your runway and establish your viability to potential investors.
Issues proving sustainability of business model
Businesses that lose control of their burn rate and never prove they can be profitable are not sustainable. As a startup, you’ll want to be as lean as possible. Track your burn rate so you’ll know if your business concept works.
How to calculate your burn rate
There are two different types of burn rates. The first, known as gross burn rate (or monthly burn rate), is the total of cash operating expenses incurred by the business each month. The other type is called the net cash burn rate. That’s your total cash inflows minus your total cash outflows. If that number is negative, you’re burning cash. If it’s positive, you’re cash flow positive.
One of the easiest ways to calculate burn rate is with your cash flow statements. Subtract the ending cash balance from the starting balance and divide by a specific time period, i.e., the number of months. For instance, if you’re using a cash flow statement from your quarterly report, the burn rate formula looks like this:
Burn Rate = (Starting Balance – Ending Balance) ÷ 3
If you’re between statements and want to look at your burn rate for the month, add up your expenses using bank and credit card statements. Revenue numbers should be registered in your accounting software. If you don’t have software set up yet, use your bank statement to count deposits. Exclude any inflows that come from venture investments.
Burn rate example
A simple example of this is your standard SaaS company. To simplify matters, let's assume all your revenues and expenses are in cash. Let’s say you pay $5,000 a month for office space, $10,000 for monthly server costs, and $15,000 for wages. That’s $30,000 in total expenses. Assume your monthly revenue is $30,000. That’s a net burn rate of zero, so you’re in good shape. Here’s what the formula looks like:
Burn Rate = ($5,000 + $10,000 + $15,000) - $30,000 = $0
Take those same numbers and apply them to an online store. This adds the additional element of cost of goods sold (COGS), which is the cost of manufacturing the products you sell. Use the same numbers, but then add in a COGS of $10,000. Your numbers now look like this:
Burn Rate = ($5,000 + $10,000 + $15,000 + $10,000) - $30,000 = $10,000
With the cost of goods sold, you’re now burning $10,000 a month. These examples emphasize the importance of including all costs and expenses when calculating your burn rate. In the scenario of the online store, missing the COGS could seriously skew the numbers. You’d be operating at a loss and not know it. That’s a recipe for failure.
4 ways to reduce your burn rate
Laying off employees or reducing salaries are knee-jerk reactions to high burn rates. Neither necessarily produces a long-term benefit. Layoffs signal that your company is on a downtrend. Lower pay rates attract less qualified prospects. There are other ways to cut your expenses:
1. Get real-time spend visibility
Cutting expenses and reducing operational costs is much simpler when you have real-time visibility into your spend. Tracking business expenses as they happen can let you know exactly how much you're spending each month. Visibility can also help you reduce expenses by identifying issues like duplicate spend.
2. Streamline your expense approval process
Streamlining the expense approval process puts you in control of your outflows. Combine this with real-time visibility functionality and your accounts payable department will have a better system for controlling costs.
3. Upgrade your tech stack
Sometimes the best way to save money is to spend in order to upgrade your tech stack. Do your homework because newer doesn’t always mean better. Look for applications and financial management software that integrates with other apps for automated data flow. Eliminating manual processes with automation is an efficient and painless way to cut your costs.
4. Automate your expense reports
Tracking expenses, organizing receipts, and compiling expense reports are all tedious jobs that waste your employees’ time. Expense automation and automated reports can save your employees hundreds of hours each month, time that can be spent on more productive work that will actually move the needle.
Burn rate limitations
While a burn rate can help you understand how much money a company is using, it can’t tell you whether the rate is sensible or disastrous.
Determining that is an internal process. In some cases, burn rates are not necessarily a bad thing. The spending can show that you’re dedicated to the development and growth of your company.
Getting to the point where you’re cash flow positive is a milestone, but most companies increase their spending at that point, settling for a manageable burn rate in exchange for additional growth or product development. That’s a good burn rate. It’s predetermined by the company, not the result of escalating and uncontrollable costs in the startup phase.
