While you can’t plan for every possible “what if,” you can put your best financial foot forward and be prepared, should an unexpected occasion arise. That’s where an emergency fund comes in: to protect you when unanticipated costs come a-knocking.

So you’re ready, we’ve assembled a quick overview of all things emergency fund — what it is, why you need it, how much you should keep in one, how and where to get started — and in case things go south, when to use it.

What is an emergency fund?

An emergency savings fund is cash you put aside for a rainy day, like an unplanned expense or financial emergency. Some common uses for your emergency savings include:

  • car or home repairs
  • medical bills
  • job loss or other unexpected decrease in income

Why do you need it?

An emergency fund can help bail you out of a tough situation. It’s an account that you can tap when you have an unforeseen expense that you can’t afford to pay for out of your regular checking account.

And it can help keep you out of further debt, because you won’t have to rely on using your credit card (and possibly being unable to pay off the balance immediately) or taking out a high-interest loan.

When you’re hit with a sudden expense, it can feel like an emergency — but that may not always be the case. Ask yourself these three questions to help you determine whether you should use your emergency savings:

  1. Is it unforeseen?
  2. Is it essential?
  3. Is it urgent?

If you can answer at least two of these questions with a yes, then it’s likely that the situation calls for you to tap into your emergency fund.

How much should you have in an emergency fund?

Knowing how much you should stash in an emergency fund might not be clear. But there are simple guidelines to follow, so you’ll be covered should you need a little extra help for when things are financially uneasy.

The short answer: Three to six months’ worth of essential expenses.

The long answer: This amount is a good rule of thumb, but it’s not a one-size-fits-all answer. The specific amount you should save will vary based on your financial circumstances and your comfort level.

Think about how much you spend each month on things like rent, utilities, food, and transit. These are considered essential expenses. Total the cost of these necessities and multiply that sum by the number of months you want to save for (six, for instance) to determine your savings goal.

When calculating how much you should have in your emergency fund, don’t include costs such as entertainment and dining — these are discretionary expenses. In your emergency fund calculation, you should only include those expenditures that you truly need to live.
