The car needs a new clutch. A tooth starts to hurt. Your employer closes the office. None of these are rare, and they rarely send a warning first. Without savings, each one becomes a loan, a or an awkward call to family. With savings, it becomes an unpleasant week. That difference is the whole idea of an .
Before we start: what do you think?
Ana earns €1,200 a month after tax and spends €900 a month on essential costs. Using the usual rule, what is a three-month emergency fund for her?
✗ That is three months of income, but the fund has to cover costs, which are €900 a month.
✓ Right: the target is based on essential costs, so 3 × €900 = €2,700.
✗ That covers one month, which is a good first step but not three months.
✗ That is twelve months of costs, far more than the usual range.
Why three to six months of costs
An emergency fund is money kept for surprises, such as losing a job, an illness or a big repair. The common rule of thumb is three to six months of essential costs. It is not a law, just a range that covers most ordinary problems.
Notice the word costs, not income. If you lose your job, you cut many wants, but you still pay rent, food, utilities, transport and loans. The from A budget that works gives you that number: it is your "needs" bucket.
Where you sit in the range depends on how risky your income is:
- Closer to three months: a stable job, two incomes in the household, few people who depend on you.
- Closer to six months or more: one income, children, self-employed work, seasonal work, or a job in an industry that often cuts staff.

Is the emergency fund target based on your income or on your costs?
Worked example: Ana's target in euros
Ana's essential costs each month:
| Item | Amount |
|---|---|
| Rent | €350 |
| Food | €250 |
| Utilities | €100 |
| Transport | €60 |
| Phone and internet | €30 |
| Loan payment | €110 |
| Total | €900 |
Three months is 3 × €900 = €2,700. Six months is 6 × €900 = €5,400.
Ana has a stable job and a partner who shares the costs, so she aims for €2,700. If she becomes self-employed, she will aim for €5,400.
Where to keep it
An emergency fund must be safe, easy to reach within a day or two, and separate from your everyday spending. Interest comes last.
A good place for most people is a at a properly licensed bank, in your own name, with no card attached. Moving the money back takes a small step, which makes you ask: "Is this really an emergency?"
In the EU, bank deposits are protected up to €100,000 per person per bank if the bank fails. Outside the EU, schemes and limits differ, so check the rules in your country.
Places that are not good for an emergency fund:
- Trading or investment accounts. Prices can fall just when you need the money.
- Crypto. The value can fall sharply in a single week.
- A loan to a friend. You cannot get it back on the day the boiler breaks.
- A large pile of cash at home. It can be stolen or lost in a fire, and it earns nothing while prices rise. A small amount for a power cut is fine. (See Inflation.)

How to build it step by step
€2,700 can feel impossible from zero. So build it in stages, and celebrate each one.
- Starter fund: €500. This covers many small surprises, like a repair or a doctor's bill.
- One month of costs. For Ana, €900.
- Three months of costs. For Ana, €2,700.
- Six months, if your income is less secure. For Ana, €5,400.
Then make the saving automatic. If Ana moves €150 on every payday, she reaches €500 in 4 months, €900 in 6 months and €2,700 in 18 months. These numbers ignore interest. At €75 a month, €2,700 takes 36 months: slower, but it still gets there.
Three ways to speed it up:
- Put part of any bonus, tax refund or cash gift straight into the fund.
- When you finish paying off a loan, keep "paying" the same amount into the fund.
- Sell one or two things you no longer use.
With expensive debt, many people build the €500 starter fund first, then attack the debt, then finish the fund. Otherwise the next surprise goes straight back onto the card. (See Debt and interest.)

Using it, and filling it again
Decide in advance what counts as an emergency. Losing your job, a medical bill, an urgent repair to your home or the car you need for work: yes. A holiday, a new phone or a sale: no. Those belong in a separate savings goal.
When you use the fund, do not feel guilty. That is what it is for. Then keep saving until it is full again.
Key takeaways
- An emergency fund covers three to six months of essential costs, not income.
- Use the low end with a stable income, the high end with one income, children or irregular work.
- Keep it safe, easy to reach and separate: a savings account in your own name works for most people.
- Do not keep it in trading, investments, or a loan to a friend.
- Build it in stages: €500, one month, three months, then six if you need it.
Try this
Add up your essential monthly costs and write down three and six times that amount. Choose your first stage, for example €500, and the amount you will move each payday. Write the date you expect to reach it.
