FAQ

Startup runway questions answered

What's the difference between gross and net burn rate?+

Gross burn = total monthly cash outflow. Net burn = gross burn minus monthly revenue. Net burn is what actually reduces your cash balance. Use net burn to calculate true runway.

How much runway should a startup have?+

Best practice: 18-24 months of runway after a raise. Start fundraising when you have 6-9 months left. Less than 6 months is "danger zone" — terms will be poor or impossible.

How do I calculate my burn rate?+

Burn rate = total monthly operating expenses (salaries, rent, software, marketing, etc.). Sum all cash outflows for the month. Exclude one-time capital expenses like equipment purchases.

What's a healthy burn rate for a pre-revenue startup?+

Pre-revenue burn should be as low as possible while making progress. Typical seed-stage pre-revenue burn: $30K-100K/month depending on team size and location. Aim for 18+ months runway.

How does revenue growth affect runway?+

Revenue reduces net burn directly. If you're growing revenue 20% monthly, net burn decreases each month, extending runway significantly. Our model shows this compounding effect.

When should I start fundraising?+

Start fundraising when you have 6-9 months of runway left. Fundraising takes 3-6 months on average. Starting earlier gives you leverage in negotiations.

How do I extend my runway?+

Three levers: increase revenue (sales acceleration), reduce costs (layoffs, marketing cuts, cheaper tools), or raise capital. Our cost reduction simulator shows impact of each cut.

What's the difference between runway and cash zero date?+

Runway = months until zero cash under current burn. Zero cash date = specific calendar month when cash hits zero. Our calculator shows both for precise planning.
