Emergency fund: how much to save, and where to keep it

A car that breaks down, a washing machine that gives up, a period without income: emergencies don't send a warning. An emergency fund is money set aside to face them without credit or overdraft. It's the first savings to build, before any other goal.

What it's for (and what it isn't)

It's for real emergencies:

• An essential repair (car, boiler, appliance)
• An unreimbursed health expense
• Losing your job or a drop in income
• An unexpected move

It's not for holidays, sales or a new phone. For those goals, keep separate savings with their own target.

How much to set aside

The most common rule: 3 to 6 months of essential expenses. Not salary, expenses: what you actually spend each month to live (rent, groceries, bills, transport, insurance).

Adjust to your situation:

• Closer to 3 months: permanent employee, stable income, few fixed costs, no dependants.
• Closer to 6 months: self-employed, variable income, children, a home or an older car to maintain.
• More: highly irregular work or an unstable sector.

A worked example

Ines spends €1,900 a month on average: rent €750, groceries €350, energy and internet €120, transport €80, insurance €60, other €540.

She's a permanent employee with no children. Target: 3 months of expenses, €5,700. If she were self-employed, she'd aim for 6 months, €11,400.

To know your real monthly spending, average your last three months. It's far more reliable than a guess, which is usually too optimistic.

Where to keep it

Three criteria: instantly available, no risk of loss, and separate from your current account so you don't spend it by mistake. An instant-access savings account ticks all three; in France, regulated accounts such as the Livret A or the LDDS are the classic choice.

Avoid stocks, crypto or anything whose value can drop just when you need the money.

How to build it, even on a small budget

• Start with a first milestone of €500 or €1,000. It already covers most small emergencies.
• Automate a transfer on payday, even €30 a month.
• Pay in one-off income: bonuses, tax refunds, cash gifts.
• Trim one spending area until you reach the goal: subscriptions, restaurants, online shopping.

At €100 a month, a first €1,000 milestone takes ten months. It's the same logic as the savings share of the 50/30/20 method: pay yourself first.

What to do when you use it

That's what it's for: no guilt. Once the emergency is over, rebuild it first, before resuming your other savings goals. And if you dip into it every month, it's no longer an emergency fund: your budget is undersized. Our guide on how to save money when you feel like you can't will help you free up room.
