Unit 2 · Level 1 · The emergency fund
Refilling without guilt
People build a buffer, then feel terrible the first time they use it. That reaction is backwards. A fund you spent on an urgent repair is a fund that did its job, and the proof is that no shares were sold and no credit card was touched. The only real mistake would be leaving it empty. Treat the balance the way you treat a fuel tank: it goes down when you drive, and you fill it again before the next long trip.
Free to play. No ads, no token, no account needed to start.
What you get asked
You spend €1,200 of your buffer on an urgent roof repair. What just happened?
The alternative was a credit card at 20% or a sale of investments on the roof's timetable rather than yours. The fund working is what a good outcome looks like.
Your buffer was €6,000 and you spent €1,800 of it. You can put back €300 a month. How many months until it is full again?
Six months. Knowing the number turns a vague worry into a short, finite task with an end date on the calendar.
Put the steps in order for what happens after a real emergency
The pause is short and it is deliberate. A few months of redirected saving costs far less than being caught empty by a second shock.
If one ordinary repair emptied the entire buffer, the honest conclusion is that the target was set too ___.
A withdrawal that clears the whole fund is information, not bad luck. Rebuild to the old number first so you are covered again, then raise the target by one month of essentials.
Why rebuild the buffer before restarting monthly investing?
Emergencies do not queue politely. A half-full buffer leaves you exposed to exactly the forced sale this whole unit exists to prevent. 🐜
The rest of this unit
The cash buffer that has to exist before any market does, because it is what stops a bad month from becoming a forced sale.
