About Burn Rate Calculator
Gross vs net
Gross burn = total cash going out per month. Net burn = expenses minus revenue (money you’re actually losing). Net is what matters for runway calculations.
Healthy runway
Early-stage startups should target 18-24 months runway after raising. With 12 months left, start raising immediately — fundraises take 3-6 months. Below 6 months is danger zone.
Reducing burn
Top categories: salaries (largest expense usually), office rent (renegotiate or sublease), marketing spend (cut paid acquisition), tooling (audit subscriptions). Layoffs are the painful but largest lever — every month of delay costs more.
