The Roth IRA changed the whole retirement savings perspective. Since its introduction, it has become a fixture in many retirement planning strategies. Here is a closer look at the trade-off you make when you open and contribute to a Roth IRA – a trade-off many savers are happy to make.

How much does the average American household have in the bank? Estimates vary, but the short answer to this question is “not enough.”

Last year, a GoBankingRates poll discovered that 57% of U.S. households had less than $1,000 in deposit accounts (although, 25% reported having at least $10,000). A 2017 analysis from Moebs Services, a research firm consulting banks and credit unions, noted that the average U.S. checking account contained around $3,600.1,2

Eyeing these numbers, you get the sense that – in an emergency – most households have less than a month before their liquid savings run out. Is this true for your household? Hopefully, your cash reserve is much larger; if that is not the case, now is as good a time as any to bolster your emergency fund.

Building up an emergency fund may be easier than you think. As financial upsets are thankfully infrequent, you have long periods of normalcy in which you can amass cash. Can you save $50 a month toward that goal? You will have $600 after 12 months if you do or $1,200 in 12 months if your spouse saves along with you. That may not seem like much, but even that little pool of cash could suffice.

Keep in mind, the whole goal of an emergency fund is to deal with sudden – and presumably acute – expenses. In the grand scheme of things, these emergency costs will likely be trivial compared to the total expense of your retirement. If you end up directing more of your money to your retirement fund than your emergency fund per month, who can blame you? Your retirement fund is presumably invested in equities and has the chance to grow and compound over time. It addresses what is arguably your top financial need – the need to provide yourself with financial stability after you end your career.

Some households need larger emergency funds than others. A high-earning, child-free couple living without much debt in a relatively inexpensive metro area might need one to absorb only 3-4 months of expenses. A family reliant on one paycheck might need one that is much larger, as severe financial trouble could surface if the breadwinner loses a job or falls ill.

Emergency funds can also help in other kinds of money crises. While an emergency is an unexpected event calling for an immediate response, you may be able to sense other financial disruptions and inconveniences coming. Maybe that garage door keeps malfunctioning or your eight-year-old computer has trouble booting up. These are signals that you will need to write a check or pull out that debit card soon.

Living without an emergency fund can invite worry. It is an anxiety too many households have had to accept. Plan to save a little each month (or more than a little, if you can manage), so that you may create a bit more financial “breathing room” in your life.
