Four figures and you know: how much runway you have in months, and the exact day it runs out if nothing changes. It is the same formula the MV Cockpit uses inside. Nothing is stored and you do not need an account.
You stop thinking “we are a bit tight” and start working against a day in the calendar. A date changes decisions; a feeling does not.
Most calculators forget it. Your salary leaves the same bank account as the rent, so here it counts as cash going out even when it is not among the expense lines.
Revenue already coming in slows the clock. If it covers the outflow, there is no deadline: that is the point of the game, and you see it instantly.
Nothing here is sent to any server. And inside the platform, your personal figures — savings, living expenses, salary — are seen by nobody but you, ever.
You divide the company’s cash by its net monthly outflow. Net outflow is expenses plus the founder’s salary minus the revenue already coming in: if you are billing, the clock runs slower. Your salary counts as outflow even if you do not list it among the expense lines, because it leaves the same bank account.
It is exactly the same concept. In Spanish we deliberately call it “meses de caja” — months of cash — because it describes precisely what it measures and anyone starting out understands it without learning jargon first. In English we keep “runway”, which is the word people already search for.
The practical rule is not to drop below twelve if you are going to raise a round, because closing investment from scratch rarely takes less than six months and negotiating with an empty bank account removes all your leverage. Below six, the priority stops being growth and becomes cutting outflow or landing revenue.
The specific day your cash runs out if nothing changes. It exists to stop you reasoning in the abstract: it is not “we are a bit tight”, it is a date in the calendar before which you need revenue, an approved grant or a closed round. Working against a date changes decisions.
No. This calculator runs in your browser and sends nothing to any server. If you create an account, the Cockpit does store your figures — and there they are private: your personal numbers (savings, living expenses, salary) are seen by nobody but you, ever.
Three things: it stores the history and tells you whether you are better or worse than months ago; it also works out how long you personally last on your savings if the company runs out; and the routine of saving those figures every week is worth up to 25 points of your MV Score (20 for consistency, 2 per week, plus 5 for having the Cockpit up and running), which is what decides whether the network’s investors see your project.
This is today’s snapshot. Inside, the same calculation is stored and warns you when it gets worse.
