Emergency funds and buffers

Money set aside for surprises turns a crisis into an inconvenience.

The idea

An emergency fund is money kept only for genuine emergencies: losing income, an urgent repair, a medical cost, a trip home you did not plan. Life brings unexpected costs; without a buffer, each one can push you into expensive borrowing, which makes the next one harder to absorb.

A common aim is enough to cover several months of essential costs — often three to six, more for people with irregular income or dependants — but any amount helps. Even one month is a real cushion. The money should be safe and easy to reach, but separate from everyday spending so it is not used by accident.

Emergency expenses are, by nature, not planned — which is why the fund is built before they happen, a small amount at a time. Setting aside a fixed amount on the day money arrives tends to work better than saving whatever is left.

Why it matters

An emergency fund turns crises into inconveniences, and lets you make calmer decisions everywhere else — about work, debt and risk.

A real example

The situation

Pedro’s car breaks down and the repair costs about half a month’s income. He has no savings, so he puts it on a card he cannot pay off quickly.

What happened

After paying the card down, he sets up a small automatic transfer to a separate savings account each payday. A year later, when his laptop fails, he pays for it from savings with no new debt.

The takeaway

He built a buffer before the next surprise, instead of relying on borrowing.

How people actually behave

People tend to believe emergencies are rare, so they under-prepare. In reality, something unexpected happens to most households most years — just not the same thing each time.

Common mistakes

• Keeping the emergency fund in the everyday account, where it gets spent.
• Investing emergency money where its value could fall when you need it.
• Using it for predictable costs, which leaves nothing for real emergencies.

Questions to think about

• What would you do today if you had to pay an unexpected cost equal to a month of expenses?
• How many months of essentials would make you feel safe?

Try it: Start your buffer

1. Work out your essential monthly costs.
2. Choose a first target — even half a month.
3. Set up a small automatic transfer into a separate account on payday.
