Frequently asked
What is burn rate?
Burn rate is how much cash your company spends per month. Gross burn is total monthly costs. Net burn is costs minus revenue — the amount your bank balance actually shrinks each month.
How do I calculate runway?
Runway = cash in the bank ÷ net burn. If you have €180,000 and burn €12,000 a month net, you have 15 months. This calculator adjusts for growth, churn and planned hires, so the runway changes month by month.
What is a good burn rate for a SaaS startup?
There is no universal number — it depends on your growth and how close you are to break-even. A common rule of thumb is to keep at least 12 months of runway, and to start fundraising with 6–9 months left.
Is this calculator accurate?
It's a simplified model: revenue compounds monthly and costs scale with hires. Real cash moves with payment delays, annual prepayments and one-off costs. Use it for direction, not for the board deck.
