Example

With $10K revenue, $25K expenses, and $200K cash, your burn rate is $15K/month with ~13 months runway.

Interpreting Your Results

Burn rate is simply how much cash a company spends beyond what it brings in each month — a company with $80,000 in monthly expenses and $50,000 in monthly revenue burns $30,000 a month, regardless of how much cash is in the bank. Burn rate alone isn't good or bad; what matters is whether it's justified by the growth or progress it's buying, and whether the company has enough runway (cash reserves ÷ burn rate) to reach its next milestone — profitability or a fundraising round — before running out. Gross burn (total expenses) and net burn (expenses minus revenue) tell different stories: a company can have high gross burn but low net burn if revenue is growing quickly, which investors generally view favorably compared to the same net burn with little to no revenue. Rising burn should always be paired with a check on what it's buying — accelerating burn alongside accelerating growth is a deliberate, often sound strategy; accelerating burn with flat growth is a warning sign.

Frequently Asked Questions

What is a good burn rate for a SaaS startup?
A good burn rate depends on your stage. Early-stage startups typically burn $50K-$200K/month with 12-18 months of runway.
What's the difference between gross burn and net burn?
Gross burn is total monthly cash expenses, regardless of revenue. Net burn subtracts revenue from expenses, showing the actual monthly cash shortfall. A company with fast-growing revenue can have high gross burn but manageable net burn.
What's considered a healthy burn rate?
There's no universal number — a healthy burn rate is one that's buying meaningful progress (growth, product development) and leaves enough runway to reach the next milestone. The same dollar amount can be healthy for a well-funded, fast-growing company and alarming for one running low on cash.
When should a startup start worrying about its burn rate?
Generally when runway drops below about 6 months, since fundraising typically takes 3-6 months to close, and starting the process too late leaves little room for negotiation or unexpected delays.
How can a company reduce its burn rate?
The two levers are cutting expenses (headcount, tools, marketing spend) or increasing revenue — most experienced operators try to protect revenue-generating activities first and cut non-essential costs before touching anything that drives growth.
Does burn rate include one-time expenses?
It can, but many operators prefer tracking a normalized, recurring burn rate that excludes one-time costs (like a large equipment purchase) to get a clearer view of the sustainable, ongoing monthly cash outflow.
Is negative burn (profitability) always the goal?
Not necessarily in the short term — many venture-backed startups deliberately run a burn rate to fund faster growth than they could achieve profitably, betting that market share and scale now are worth more than early profitability, as long as runway supports the strategy.
