The laptop dies
Your laptop stops working two weeks before coursework is due. A replacement is $300. You have $310 saved and no other way of getting the work done.
What do you do?
Step 1: What Would You Do?
There is often more than one good answer. Pick one and see what happens.
Step 2: What That Was
The name for what you just worked out.
Some months cost more than others, and the extra is never planned. A phone dies. A car needs a part. Savings are what turn that from a crisis into an annoyance.
Some costs do not move
Rent, phone contract, travel to work — these arrive whatever kind of month you are having. Knowing that total tells you what a bad month actually costs.
Fixed costs are the ones that arrive whether you use them or not.
A first target
A common starting point is one month of fixed costs. Not because that is enough for everything — because it is small enough to be reachable, and it covers most single surprises.
The alternative is borrowing
Without savings, an emergency is paid for with credit, which means paying more for the same thing. That is the real return on an emergency fund.
Step 3: Try It
These ones do have right answers.
Fixed or Not?
Sort these into costs that arrive anyway and costs you control month to month.
Which of these are fixed costs?

Step 4: Somewhere Else
Same thinking. Different situation.
Not money at all
You have a deadline in a week. You plan the work to fill exactly seven days, with no spare time.
Does the emergency-fund idea apply here?
Step 5: Quick Check
Two questions, then you are done.
Question 1 of 1
What is the main thing an emergency fund saves you from?
Step 6: Your Life Mission
Something to do away from the screen. Nobody is checking.
Find your fixed number
- List every cost that would arrive next month whether or not you did anything.
- Add them up.
- Write that number down somewhere you will find it again.
Why: Nearly every later money decision refers back to this one figure.
For a grown-up: Doing this on the household’s real numbers is a substantial conversation. An invented set works just as well for the skill.
Step 7: What You Learned
- Bad months are not planned, but they are predictable.
- Fixed costs arrive whatever kind of month it is.
- One month of fixed costs is a reachable first target.
- Without savings, emergencies are paid for with credit.
For the grown-up
The emergency fund is the highest-value idea in personal finance for anyone on a low income, and it is routinely taught after investing, which is the wrong order for almost everybody.
Watch for the target being set too high. "Three to six months" is standard advice and, to someone earning very little, it reads as impossible and produces nothing. One month is reachable and does most of the work.
Naming what it is for helps: a fund labeled "the month the car breaks" survives temptation better than one labeled "savings".
