Burn rate is a KPI used to describe how fast a company is spending it's cash to fund the entire operation. Typically burn rate is measured in cash spent per month. Burn rate essentially measures how many months a company can stay in business before running out of cash. Let's take a quick example: If your company has $100,000 USD in cash on hand with a burn rate of $25,000 USD per month, your company will run out of cash in four months.
Yep that's right, running out of cash is the leading cause of death for startups across the world. You can't take your cashflow for granted or ignore your burn rate because well, it's the life blood of your company. Being aware of your burn rate, what you're spending the money on, and what levers you could potentially pull in order to reduce it are all essential to being a successful startup or small business founder.
A high burn rate is often times an indicator of over spending...did you really need to buy all those bean bags and that neon company logo sign for the office? Probably not. The three most common areas startups and small businesses over spend in are branding, vendor relations, and office space.
There are actually two core burn rate formulas: Gross burn rate and Net burn rate. Let's look at how to calculate both of them below.
Gross burn rate is all about measuring efficiencies of businesses and excludes new revenues (that are hopefully) flowing in to the business.
Gross burn rate = cash on hand / monthly operating expenses
Net burn rate is the rate at which a company is losing money. It essentially shows how much cash a company needs to continue operating over a period of time. A fall in revenue with no change in costs can lead to a higher burn rate.
Net burn rate = cash on hand / monthly operating losses
OK so you can compute both gross burn rate and net burn rate for your business, but which is better or more frequently used? In short, both are important to the longevity of your business. If you're talking to a peer, investor, or mentor and they ask simply, "what is your burn rate?", you can assume they're referring to your gross burn rate.
Often times you will only hear about burn rates in the startup world but burn rate is equally important to mature growth stage companies as well. Burn rate is an extremely useful KPI as a means of measuring cash reserve, building and targeting later investments.
The idea for Default Alive or Default Alive comes from the wonderful mind of Paul Graham, the legendary entrepreneur, investor, and founder of Y Combinator.
In Paul's essay he says that one of the first questions he asks a startup founder is, "are you Default Alive or Default Dead?". What Paul is trying to ask in layman's terms is - based on current expenses, growth rate, and cash on hand - is the business on the right trajectory to reach profitability before running out of money. If yes, then that business is Default Alive. If no, they are Default Dead.
Paul asks this question because for starters, most founders don't know their finances - Do you know whether you're Default Alive or Default Dead as of reading this? Founders that know the answer to this question have a clear understanding of their finances and are signaling to Paul and other early investors that they're serious about monitoring the performance of their business. The second reason Paul asks this question is to understand where to take the conversation next. If they're Default Alive, Paul likes to talk about new ideas and growth strategies, with the later, the conversation turns to how the business can avoid an almost certain death. Here's the link to the original essay from 2015, it's a good one!
