The emergency fund: how much you need before you start investing

The emergency fund (or safety cushion) is the money you set aside for the unexpected —losing your job, a breakdown, a medical bill— that lets you cope without going into debt or having to sell your investments at the worst moment. It is the first step of any financial plan, even before you start investing.

How much should I hold?

The common rule is between 3 and 6 months of your expenses (not your income). Exactly how much depends on your situation:

• 3 months may be enough with a stable job, two household incomes, or few obligations.
• 6 months or more if your income is variable (self-employed), you rely on a single salary, or you have dependents.

Work out your real monthly spending and multiply. If you spend €1,500/month, your cushion would be between €4,500 and €9,000.

Where to keep it?

The emergency fund is not invested in the stock market. Its goal is not to grow, but to be available and safe when you need it. It must meet two conditions:

• Liquidity: you can withdraw it within hours or a few days.
• No risk of losing value: no stocks or equity funds, which can fall precisely when you need the money.

Typical options are a high-interest savings account, a short-term deposit, or a money-market fund. Prioritise availability over return: here the goal is peace of mind, not maximising interest.

Why it comes first, before investing

Without a cushion, any surprise forces you to sell your investments —perhaps at a loss if the market is down— or to take on expensive debt. The emergency fund is exactly what lets you keep your investments intact and let compound interest work for years without interruption. It is also what gives you the calm not to panic-sell during a crash.

The sensible order

1. Build your emergency fund (3-6 months of expenses), liquid and safe.
2. Clear expensive debt (credit cards, consumer loans).
3. And only then: start investing for the long term in a diversified way (see what diversification is).
