Emergency fund: how much should you keep aside?
Updated October 6, 2026 · By the Souski team
A car breakdown, an unexpected bill, a drop in income: an emergency fund lets you absorb the blow without going overdrawn or borrowing. How much to keep, where to hold it and how to build it up step by step.
What is an emergency fund for?
It's money set aside for the expenses you can't predict: repairs, medical costs, an appliance to replace, a period without work. Without it, every surprise goes on your overdraft or a loan, which are expensive in fees and interest.
It has a less visible effect too: you make better decisions when you're not counting every €200.
How much should you keep aside?
The most common rule of thumb is 3 to 6 months of everyday spending. The right amount depends on your situation:
- Closer to 3 months if your income is stable (permanent contract, public sector) and you have few commitments.
- Closer to 6 months or more if your income varies (self-employed, temping, commission), if you have children, or if you own your home (surprise repairs).
Base it on your spending, not your income. If you spend €1,500 a month, the target is between €4,500 and €9,000.
That can feel like a lot. Start with a first milestone: €500, then one month of spending. That already covers most small surprises.
Where should you keep it?
Three things matter: the money must be quickly accessible, with no risk of loss, and kept separate from your current account so you don't spend it by accident.
An easy-access savings account at a regulated bank ticks these boxes: you can withdraw at any time and deposits are protected (up to €100,000 per bank in the EU, with similar schemes elsewhere). Rates change over time, so compare the current ones before choosing.
How to build it, even on a tight budget
- Set a target and a date, for example €1,500 in 12 months. The savings goal calculator gives you the amount to put aside each month.
- Set up a standing order for payday. What you don't see in your current account, you don't spend.
- Find the money in your budget: trimming one category by €30 or €50 is often enough to get started. Our guide How to make a budget helps you spot it.
- Add one-off windfalls: a bonus, a refund, a birthday gift. Part of it goes straight into the fund.
When can you dip into it?
Only for a real emergency that's necessary and urgent. Sales, a trip or a new phone don't count: those are plans, and they deserve their own savings goal. Once you've used some of the fund, rebuilding it comes first.

Frequently asked questions
Should I pay off debt before building an emergency fund?
Build a small cushion first, even a few hundred euros, so the first surprise doesn't push you into your overdraft or onto a credit card. Then you can speed up repaying your most expensive debts while still topping up your fund.
Can I invest my emergency fund in the stock market?
It's not recommended: this money needs to stay available and stable. If a crisis hits while markets are down, you'd have to sell at a loss.
What should I do after using my emergency fund?
That's what it's for. Simply restart your deposits until you're back to your target, before going back to your other savings plans.
