What Is an Emergency Fund?

An emergency fund is money set aside specifically for unexpected expenses — a car repair, medical bill, job loss, or broken appliance. It's not for planned expenses or holidays; it's your financial safety net.

The Money Advice & Budgeting Service (MABS) recommends having a "rainy day fund" as one of the first steps in any financial plan. Without one, a single unexpected expense can lead to debt or missed bills.

How Much Should You Save?

Financial experts generally recommend:

3 months of expenses — A good starter target. Covers most short-term emergencies like car repairs or temporary income disruption.
6 months of expenses — The recommended full target. Provides a cushion for longer-term setbacks like job loss or extended illness.

Your "monthly expenses" means your essential spending: rent/mortgage, groceries, utilities, transport, and insurance. Not discretionary spending like entertainment or dining out.

Example: If your essential monthly expenses are €2,500, your targets would be:

3-month fund: €7,500
6-month fund: €15,000

Where to Keep It

Your emergency fund should be:

Instantly accessible — You need to reach it within 1-2 business days
In a separate account — Keep it away from your day-to-day spending to avoid dipping into it
In a savings account — Earn some interest while it sits there. Many Irish banks offer instant-access savings accounts

Do not invest your emergency fund. The whole point is that it's there when you need it, without waiting for markets to recover.

How to Start

Calculate your target — Use Cisti's emergency fund goal to auto-calculate based on your budget
Set a monthly amount — Even €100/month adds up. Consistency matters more than the amount
Automate it — Set up a standing order to your savings account on payday
Start small — An initial target of €1,000 provides immediate peace of mind while you build toward the full 3-6 month target
