How to build an emergency fund

An emergency fund is money you put aside to cover a financial shock, such as losing your job, or for a large, unexpected expense.

Building an emergency fund can help prevent you needing to borrow money or make difficult financial decisions in those moments, by giving you savings to fall back on.

How much you need, and what an ‘emergency’ is, will depend on your situation. 

You can use our emergency fund calculator to help work out how much you may want to save for your emergency fund. You can input your essential spending for the month, and the calculator will work out how much you need to save and how long it would take you to reach this goal.

If you need more help planning an emergency fund, here are some steps to get started.

1. Decide how much you need

It’s recommended you have at least 3 months’ worth of living expenses in an emergency fund. If your total monthly outgoings – including rent or mortgage payments – are £2,000, you should aim to have at least £6,000 set aside. However, the more you can save, the better. 

A bigger emergency fund can help make sure you’re able to handle a large financial shock, so you may want to aim for 6 months’ worth of living expenses. If your monthly outgoings are £2,000, for example, you’d ideally have £12,000 in your emergency fund.

It may take you a while to save up, but even a small emergency fund is better than nothing, so don’t be discouraged.

Start by looking back at your expenses over the last 3 months to see how much you spend. Then use a budget to work out how much you could save into your emergency fund each month. You could use our budget planning tool to help.

2. Start saving

Based on the amount you’ve decided to save, how long will it take to reach your emergency fund goal? 

It helps to keep a target date in mind and set milestones along the way so you can celebrate progress. Use our savings goal calculator to help see how long it would take to reach your target. 

You may want to open a separate savings account for your emergency fund so you’re not tempted to dip into it. Plus, you may be able to earn some interest to add to your savings. Ideally, you want to be able to access the money quickly, if you need it – so you don’t want it to be in a locked savings account, or invested.

A good way to stick to your savings plan is to set up a standing order to move money into a savings account each month. If you schedule it for the day you get paid, you’ll lower the temptation to spend it.

You can also put extra money into your savings account whenever you want. If you have money left over at the end of a month, why not add it to your savings?

3. Make a clear plan

Whether you’re building an emergency fund for yourself or with someone else, make a clear plan from the outset.

What is an emergency and when will it be OK to use the money? Examples could be:

  • job loss
  • medical bills
  • car or home repairs

Set these out so you’re not tempted to spend the money on something else you may regret later.

4. Keep it topped up

If you do have to use your emergency fund, make a plan to top it back up. It’s important not to let it shrink over time.

It’s also worth assessing your emergency fund on a regular basis. Your expenses can change, so what was 3 months’ worth of expenses a year ago may no longer be enough.
