What is a good burn rate for a startup?

A good burn rate is one that allows you to maintain at least 12 to 18 months of runway while making meaningful progress toward your milestones. There is no universal dollar figure. The right burn rate depends on your stage, your funding, and the efficiency of your spending relative to the progress it produces.

What is the difference between gross burn and net burn?

Gross burn rate is total monthly spending regardless of revenue. Net burn rate is monthly spending minus monthly revenue. For pre-revenue startups, the two figures are identical. For startups with revenue, net burn gives a more accurate picture of how quickly cash is being depleted and is the figure used in runway calculations.

How does burn rate relate to runway?

Burn rate directly determines runway. Runway equals cash on hand divided by monthly net burn rate. A higher burn rate shortens runway; a lower burn rate extends it. Because this relationship is direct, any change to burn rate has an immediate and calculable impact on how long the company can operate.

What Is a Good Burn Rate?

A good burn rate is one that sustains meaningful progress while preserving enough runway to reach your next milestone. The number itself is less important than what it produces.

There is no universal “good” burn rate. The right figure is the one that maintains 12 to 18 months of runway while funding the activities that drive your company forward.

Burn rate is the speed at which a startup spends cash. Gross burn is total monthly spending. Net burn is spending minus revenue. For pre-revenue companies, these figures are the same. For companies with income, net burn is the more relevant number because it reflects the actual rate of cash depletion.

The question of whether a burn rate is “good” can only be answered in the context of what it produces. A company spending $100,000 per month and growing 20% month over month is in a different position than one spending $100,000 per month with flat metrics. The burn rate is identical; the quality of the spending is not.

Gross burn versus net burn

This distinction is fundamental and frequently confused. Gross burn counts every dollar spent. Net burn subtracts revenue from that total. The difference determines which figure is appropriate for your situation.

Gross burn rate

Total monthly operating expenses. Useful for understanding the full cost structure of your business, regardless of revenue.

Net burn rate

Monthly expenses minus monthly revenue. This is the figure used in runway calculations and reflects how quickly your cash reserves are actually declining.

For early-stage companies with no revenue, gross and net burn are the same. As revenue grows, the gap between them widens. Monitoring both figures gives you a complete picture: gross burn tells you your cost structure, net burn tells you your cash depletion rate.

How burn rate varies by stage

Pre-seed and seed

At the earliest stages, burn rates are typically low because teams are small and infrastructure costs are minimal. A monthly burn of $20,000 to $80,000 is common. The priority is capital efficiency: getting the most learning and product development out of each dollar spent.

Series A

After a Series A, burn rates typically increase significantly as companies hire aggressively and invest in go-to-market. Monthly burn of $150,000 to $400,000 is not unusual. The key question at this stage is whether the increased spending is producing proportional growth. If burn doubles but metrics stay flat, the spending is not working.

Series B and beyond

At later stages, the absolute burn number matters less than the relationship between burn and revenue growth. A company burning $500,000 per month with $400,000 in monthly revenue has a net burn of $100,000, which may be perfectly sustainable. The focus shifts from burn rate alone to burn efficiency and the path to profitability.

Common misconceptions

“Lower burn is always better”

Underspending can be as damaging as overspending. A company that maintains an extremely low burn rate but fails to invest in product, hiring, or distribution may preserve runway at the cost of growth. The goal is not to minimize burn but to optimize the return on each dollar spent.

“Burn rate is just about expenses”

Burn rate is the net result of both spending and revenue. Reducing burn by cutting costs is one approach. Reducing net burn by increasing revenue is another. Both have the same mathematical effect on runway, but they carry very different strategic implications.

“You can evaluate burn rate in isolation”

A burn rate number without context is meaningless. $200,000 per month is aggressive for a 4-person team and conservative for a 40-person team. Burn must be evaluated relative to team size, stage, growth rate, and the milestones it is funding. Investors look at this context when evaluating whether a startup's spending makes sense.

“Reducing burn always extends runway proportionally”

Cutting $10,000 from a $50,000 monthly burn extends runway more proportionally than cutting $10,000 from a $200,000 burn. The impact of burn reduction depends on your total spend, and understanding your cash flow patterns is necessary to predict the actual runway effect.

Practical founder implications

Rather than asking “is my burn rate good?”, the more productive question is “what is my burn rate producing, and does it sustain the runway I need?”

Start by calculating your net burn accurately. Use actual trailing expenses and collected revenue, not projections. Then connect that figure to your runway: at your current net burn, do you have enough months to reach your next milestone and complete a fundraise?

If the answer is no, you have two options: reduce burn or accelerate revenue. The choice between them depends on which approach is more likely to improve your position for the next raise. Sometimes cutting a role extends runway by 2 months. Sometimes adding a role that drives revenue has a larger net effect. The analysis requires looking at both sides.
