How much to save for an emergency fund, and how long it takes

There is no single correct size for an emergency fund. The Consumer Financial Protection Bureau says the amount depends on your situation. What you can do is set a target from your own costs and work out how long it will take to reach.

What an emergency fund is

The CFPB describes an emergency fund as a cash reserve specifically set aside for unplanned expenses or financial emergencies, such as car repairs, home repairs, medical bills or a loss of income. It is different from savings for a planned goal like a holiday, which is better handled as a sinking fund.

Setting a target from your own costs

The CFPB suggests thinking about the most common unexpected expenses you have had and how much they cost. Two practical ways to turn that into a number:

  1. A shock-based target. Add up the cost of one or two typical surprises: a car repair, an insurance excess, a replacement appliance.
  2. A months-of-essentials target. Add up essential monthly costs, such as housing, food, utilities, transport, insurance and minimum debt payments, and multiply by the number of months you want covered.

Many people quote “three to six months of expenses”. That is a common rule of thumb, not a requirement or an official standard; the right figure depends on how stable your income is, who depends on you and what other help you could rely on.

Interest helps only a little over short periods. The monthly amount is what moves the date.

Ways to build it

The CFPB’s guide describes several strategies:

  • Create a savings habit with a specific goal and regular contributions.
  • Manage cash flow, for example by adjusting bill due dates.
  • Save one-off money such as a tax refund or a cash gift.
  • Make saving automatic with recurring transfers.
  • Save through work by splitting your pay between accounts, if your employer allows it.

If your income varies, see saving with irregular income.

Where to keep it

The CFPB says the fund should be safe, accessible and somewhere you are not tempted to spend it. Options it lists include a bank or credit union account, a prepaid card and cash, noting that cash can be stolen, lost or destroyed. Because the money must be available quickly, it counts in your liquid net worth.

Using it and rebuilding

Decide in advance what counts as an emergency, and stay consistent. If you use the fund, the CFPB’s advice is not to be afraid to use it and then work to build it up again.

Questions people ask

Should I build an emergency fund before investing?

It depends on your situation, including your debts and any employer retirement match. See pay off debt or save for the factors to compare.
