Dear Liz: You recently advised a teacher who was inquiring about paying down student debt. You suggested among other things to “have a substantial emergency fund before you make extra payments on education debt (or a mortgage, for that matter). ‘Substantial’ means having three to six months’ worth of expenses saved. If your job is anything less than rock solid, you may want to set aside even more.” Granted, this is in the context of the student debt question, but is that emergency fund advice still valid in light of studies showing the liquidity needs of lower-income households to be much lower?

Answer: The usual advice about emergency funds is often unrealistic and sometimes absurd for most low- or even moderate-income households.

The advice is usually given by financial planners who typically work with higher-income clients. The higher your income, the more likely it is that you have the free cash flow to quickly build a large emergency fund.

An analysis in the New York Times found that a household with income over $200,000 would need about two months to save one month’s worth of expenses. A household with income of $70,000 to $99,999 would need seven to eight months to save one month’s worth. A typical household with two or more people and income of $50,000 to $69,999 would need more than two years to save a single month’s worth of expenses.

As you’ve noted, though, various studies have found that much smaller emergency funds can help households avoid catastrophe.

A 2015 study by Pew Charitable Trusts found the most expensive financial shock suffered by the typical household amounted to $2,000. But as little as $250 can reduce the odds that a low-income household will suffer serious financial setbacks such as eviction, according to a 2016 Urban Institute study.

A three-month emergency fund could be a long-term goal, but it’s not something that should be prioritized over more important tasks such as saving for retirement or paying off high-rate debt.

Such a fund should be a priority, however, over paying off lower-rate, potentially tax-deductible debt. That’s especially true when you’d be making extra payments on student loans. Paying down credit cards can free up additional credit to be used in an emergency, but payments sent to student loan lenders are gone for good.
