Qu'est-ce que le/la Burn rate ?

Le burn rate mesure la vitesse à laquelle une entreprise – typiquement une start-up non encore rentable – consomme ses réserves de trésorerie chaque mois.

Gross burn is total monthly cash outflow; net burn is the same minus any revenue received. Investors monitor burn alongside runway to judge whether a startup will reach profitability or its next financing round before running out of cash.

Sustainable burn is justified when each franc spent reliably generates more than a franc of future enterprise value — through customers, product, or strategic position. Uncontrolled burn is the classic killer of venture-backed companies.

Formule
Net Burn Rate = Monthly Cash Out − Monthly Cash In
Exemple

A SaaS startup spends CHF 350k per month on salaries, hosting and marketing while collecting CHF 100k in subscriptions — net burn is CHF 250k per month.
