The emergency fund: how big, where to keep it and when to use it
Calculate an emergency fund target for your situation, choose a safe place to hold it, and set clear rules for using and refilling it.
What you will learn
- How to calculate an emergency fund target from essential expenses, not income.
- Which personal factors justify a smaller or larger fund.
- Where to keep the money and where not to keep it.
- A three-question test for using the fund and a plan for refilling it.
Explanation
An emergency fund is money set aside only for unexpected, necessary costs or a sudden loss of income: a broken washing machine, a car repair you need for work, a dental bill, or a gap between jobs. Its job is to stop a surprise from turning into expensive debt or a forced sale of investments.
How big? Start from essential expenses
Size the fund in months of essential expenses. Essential expenses are the costs you would still pay in a crisis after cutting all wants: rent, energy, food, insurance, transport, minimum debt payments. (your needs total from Lesson 2). A widely used rule of thumb is three to six months of essential expenses. It is a guideline, not a scientific result, so adjust it to your situation:
| Points toward a smaller fund (around 3 months) | Points toward a larger fund (6 months or more) |
|---|---|
| Permanent employment contract, in-demand skills | Fixed-term contract, probation period, or self-employment |
| Two incomes in the household | One income, or children or other dependants |
| Renting, newer car or no car | Owning a home or an older car (repair risk) |
| Good insurance cover | High insurance deductibles or gaps in cover |
In Germany, employees who pay into statutory unemployment insurance can usually receive Arbeitslosengeld I after losing a job, subject to conditions. It replaces only part of previous net pay and payments can start late or be blocked for a period after a self-initiated resignation. Check the current rules with the Bundesagentur für Arbeit. Self-employed people usually have no such safety net, which is why they need a larger fund.
Where to keep it
The fund must be safe, available within one or two days, and separate from your everyday account. In practice this means an instant-access savings account (Tagesgeld) at a bank covered by statutory deposit protection; Lesson 5 explains both in detail.
- Not on the current account: money you see every day gets spent.
- Not all in a fixed-term deposit (Festgeld): you usually cannot withdraw before the term ends.
- Not in shares, ETFs or crypto: their value can fall sharply exactly when the economy is weak and job losses are more likely. You could be forced to sell at a loss.
Inflation slowly reduces the buying power of cash (see the Macro course); that is the accepted cost of safety. Review the target yearly.
When to use it: the three-question test
- Is it unexpected? (A yearly insurance bill is not; plan it as a sinking fund, Lesson 8.)
- Is it necessary? (A repair to get to work is; a holiday deal is not.)
- Is it urgent? (Must it be paid now, or can it wait and be saved for?)
Only three "yes" answers justify using the fund. Afterwards, refilling it is the top savings priority.
Emergency fund and debt
If you have expensive debt such as an overdraft or a credit card, a practical order is: first a starter buffer of about one month of essential expenses, then pay down the expensive debt (Lesson 4), then build the full fund.
Worked example
Hypothetical example: Lena (Lessons 1–2) has essential expenses of €1,810 per month. She is on a permanent contract, single, renting and owns a car. All figures are invented and rounded; interest on savings is ignored.
Step 1: Three months = €1,810 × 3 = €5,430. Six months = €1,810 × 6 = €10,860.
Step 2: Choose a target. Permanent contract points to the lower end, the car to a little more. She chooses four months: €1,810 × 4 = €7,240, rounded to €7,250.
Step 3: Gap. She already has €5,000 in instant-access savings. Gap = €7,250 − €5,000 = €2,250.
Step 4: Time to close the gap. She saves €400 per month (Lesson 2) and sends €250 to the fund: €2,250 ÷ €250 = 9 months. The other €150 goes toward the credit card balance.
Step 5: Use and refill. In month 12 the car needs a €900 repair. Unexpected, necessary, urgent: yes. She pays from the fund and refills it at €250 per month: €900 ÷ €250 = 3.6, so about 4 months.
Common mistake
Practice activity
Hypothetical case: Murat is self-employed with two children. His household's essential expenses are €2,600 per month. He has €4,000 saved and can add €350 per month. (a) Which end of the range fits him and why? (b) Calculate the six-month target. (c) How many months until he reaches it?
Show solution
(a) The upper end or more: self-employed income is less predictable, there is usually no unemployment benefit, and he has dependants.
(b) Target = €2,600 × 6 = €15,600.
(c) Gap = €15,600 − €4,000 = €11,600. Months = €11,600 ÷ €350 ≈ 33.1, so about 34 months (almost three years).
Limitations: this ignores interest, inflation and possible changes in expenses; a long build-up time is normal and the fund still helps at every stage.
Key takeaways
- Size the fund in months of essential expenses; three to six months is a common rule of thumb.
- Job security, dependants, home ownership and self-employment change the right size.
- Keep it in a separate, deposit-protected instant-access account, not in investments.
- Use it only for unexpected, necessary and urgent costs, then refill it first.
