Burn Rate: The Number Every Founder Must Monitor Every Month

Burn rate is the speed at which your startup is spending money. If you raised €500,000 and you're spending €50,000/month net, your burn rate is €50,000/month and you have 10 months of runway. Simple concept — but the details matter enormously.

Gross Burn vs Net Burn

Gross burn: total monthly expenditure before any revenue. Net burn: monthly expenditure minus monthly revenue.

Most investors and founders focus on net burn, because revenue reduces how quickly you're consuming capital. If you spend €80,000/month but earn €30,000 in revenue, your net burn is €50,000.

Early-stage startups with no revenue have gross burn = net burn.

What's a Healthy Burn Rate?

There's no universal answer, but general principles:

• Pre-product: burn should be minimal (primarily founder salaries and essential infrastructure)
• Early traction: burn should scale proportionally with demonstrable progress
• Growth stage: burn can be higher if unit economics are proven and growth is capital-efficient

VCs typically want to see companies reach their next milestone with capital to spare — ideally with 6 months of runway remaining to allow time for fundraising.

Common Burn Rate Mistakes

• Hiring too fast: payroll is the dominant cost for most startups. Every hire locks in ongoing fixed cost
• Expensive office space: coworking or remote-first saves significant capital early on
• Software sprawl: auditing your SaaS stack monthly often reveals €1,000–€5,000/month in unused tools
• Agency dependency: outsourcing marketing and development can accelerate burn dramatically

Extending Your Runway Without More Funding

1. Reduce headcount costs: restructure before you run out of time — not after
2. Renegotiate vendor contracts: most SaaS vendors have annual discounts
3. Focus on revenue: even €5,000/month in revenue reduces burn by €5,000 — the mental shift matters as much as the money
4. Delay hiring: use contractors for short-term needs
5. Government grants: Luxembourg's FEDER and Fit 4 Start programmes provide non-dilutive capital
