The emergency fund
Size a buffer from your essential costs, keep it somewhere safe and reachable, and learn how people balance safety against losing value when prices rise fast.
Emergency fund
Money set aside for costs that are unexpected, necessary and urgent. It is not a savings goal. Its job is not to grow; its job is to be there on the worst day of your year, so you don't have to borrow at a bad rate or sell something at a bad time.
A trip you booked, a bill that arrives every spring and a phone you'd like are none of these three things. Those belong in the budget, not the fund.
Sara's buffer, sized from ESSENTIALS only
Rent + bills 1,250
Food 600
Transport 250
----------------------------------
Essential costs / month 2,100
3 months = 2,100 x 3
6 months = 2,100 x 63 months = 6,300
6 months = 12,600Her total spending is 2,880 a month, but a buffer is for surviving, not for living exactly as before. Sizing on essentials makes the target smaller and reachable.

Four things happened to Mina this year. Which one is what an emergency fund is for?
- A phone she had been wanting for months went on sale
- Her yearly car insurance bill, which arrives every spring like clockwork
- The summer holiday she takes with her family every year
- Two weeks of lost income when she was ill and could not work
Show the answer
Two weeks of lost income when she was ill and could not work
Right. It was unexpected, it hit her income and she couldn't postpone it. The other three she could see coming, so they belong in the budget.
How big, and what it must be
- Three months of essential costs is a common starting size for someone with a steady salary and nobody depending on them.
- Six months or more makes sense with irregular income, a single earner in the household, people who depend on you, or a job that is hard to replace quickly.
- Safe: the amount must still be there when you need it. This is not money you can afford to see fall by a third in a bad month.
- Reachable: you can turn it into spendable money within a day or two, without a penalty and without asking anyone's permission.
- Separate: not in the account you spend from. Money you can see is money you will use.
Two kinds of money, two different jobs
Buffer money
Job: be there. Judged only by whether it survives and whether you can reach it. A buffer that earned a lot but was locked up for a year failed at its job. Size it, then stop adding to it.
Long-term money
Job: grow. Judged over years, not months. It is allowed to fall in value on the way, because you are not going to need it next Tuesday. Module 3 is about this money.

THE SQUEEZE
When prices rise fast, waiting money shrinks
A buffer has a cost, and in a high-inflation economy that cost is large. Money sitting still buys less each month, even though the number on the screen never changes. If prices rise 40% in a year, a buffer that covered six months of essentials at the start covers roughly four and a half by the end, unless you top it up.
This is not a reason to skip the buffer. It is a reason to size it honestly, top it up as prices move, and not hold far more of it than your situation needs.
Check yourself
Reza has six months of essentials sitting in a buffer and a loan at a very high rate. Keeping the full buffer while the loan runs costs him nothing.
Show the answer
False
It costs him the interest he keeps paying on the loan, plus whatever the buffer loses to rising prices. That's why many people hold a small starter buffer first, clear the most expensive debt, and only then build the fund up to three or six months. Lesson 5 works through the order.
Build it without waiting for a good year
- Start with one small target
Half a month of essentials, or whatever round number feels reachable. A buffer that exists and is small beats a perfect one you never start.
- Give it its own place
A separate account, so the balance you spend from never includes it. Out of sight is the whole point.
- Make it automatic on payday
This is the pay-yourself-first move from lesson 2, pointed at one target.
- Add every windfall
A bonus, a refund, money back from something you returned. These arrive outside the budget, so sending them here costs you nothing you were already counting on.
- Refill after every use
Using it is not failure; that is what it is for. The rule is that refilling it goes back to the top of the list before anything else restarts.
Check yourself
Negar works freelance, her income swings from strong months to thin ones, and she helps support her mother. Sara is salaried with a stable job and nobody depending on her. Who has the stronger reason to aim closer to six months than three?
- Sara, because a steady salary makes a large fund easier to build
- Neither: three months is the right size for everyone
- Negar: her income is unpredictable and someone depends on it
- Negar, but only until one large invoice lands
Show the answer
Negar: her income is unpredictable and someone depends on it
Yes. The size follows how likely and how long a gap in income could be, and how many people it would hit. Both of Negar's factors push the target up.
A spare tyre
Nobody buys a spare tyre hoping to use it, and nobody judges it by how fast it goes. It is judged by one thing: being in the boot when you need it. Where the analogy breaks: a spare tyre keeps its value sitting in the dark, and your buffer does not. Money left alone in a high-inflation year quietly deflates, which is why you re-check its size instead of setting it once and forgetting.

Match each part of the idea to what it means in practice
Show the answer
- Three months of essential costs → A common starting size for a stable salary
- Six months or more → Irregular income, one earner, or dependents
- Reachable → Cash in your hands within a day or two, no penalty
- The fund gets used → Refilling it goes back to the top of the list
- Prices rose 40% this year → The target amount has to rise too
Lesson recap
- An emergency fund covers costs that are unexpected, necessary and urgent. Predictable costs belong in the budget.
- Size it on essential monthly costs: three months with a steady salary, six or more with irregular income or dependents.
- It has to be safe, reachable within a day or two, and kept separate from the account you spend from.
- Where prices rise fast the buffer loses value while it waits, so top up the target and hold no more than your situation needs.
- Build it automatically on payday, feed it windfalls, and refill it before anything else after you use it.
