What is an emergency fund?

An emergency fund is a dedicated, easily accessible cash reserve, ideally holding enough liquid cash to cover essential living expenses for several months. This money should be set aside specifically for unexpected financial surprises like job loss, medical bills, or major car repairs. It is a foundational element of financial security and should be viewed as a pillar of good financial planning.

A proper emergency fund reduces anxiety by eliminating uncertainty around how to cover unexpected expenses or bridge gaps during periods of unemployment, without relying on credit cards or high-interest loans when crises occur.

The funds should be kept in a separate, safe, and liquid account, such as a high-yield savings account, that is easily accessible but not mixed with day-to-day funds for regular cash flow.

Why an Emergency Fund is Important

  • Job loss protection: It provides a financial cushion if you lose a primary source of income.

  • General financial safety net: It serves as a buffer between your long-term financial strategy and life’s unexpected expenses, helping ensure goals like retirement remain on track and unnecessary debt it avoided when surprises happen.

  • Peace of mind: Knowing you have funds for unexpected bills, such as major auto or home repairs, reduces stress and anxiety and enables financial flexibility.

Note: Emergency funds don’t need to cover non-essential expenses. This is a mistake a lot of generalized recommendations make. Not only is “3-6 months” too vague to be helpful, it is lumps in discretionary expenses with essential expenses. This is wrong. Emergency funds are for necessities only and this distinction often cuts the required size of an emergency fund by half in many households.

I’ve had someone tell me that building a proper emergency fund is too onerous. At the same time, this person also said that their golf membership is an essential expense (nonsense).

There is a way to balance needs and wants, but in a real financial emergency, you have to prioritize the expenses that keep you and your family alive and safe. That is the bare minimum for an emergency fund.

Explaining the Emergency Fund Resilience Index (EFRI)

In order to better evaluate how much money someone should be keeping in their emergency fund, we need to be able to measure the relative safety of the labor market. A household doesn’t need to keep the same amount of cash on hand during all types of labor market environments.

The purpose of the EFRI is to help zero in on the number of months an emergency fund should last, given the latest conditions in the labor market. The traditional recommendation that individuals or families keep “3-6 months” of expenses is vague and unhelpful because there are many relevant factors in both a household’s finances and the broader labor market that should influence the size of an emergency fund.

In a tight and competitive labor market, emergency funds do not need to be excessive. The less slack there is in the labor market, and the easier it is to find a new job, the greater the opportunity cost of holding excessive idle cash.

In periods of looser labor markets, where layoffs are high or rising or hiring is slow, the risk of running out of an emergency fund during periods of joblessness needs to be managed. Building an emergency fund that aligns with both the risk of layoff and the expected duration of unemployment offers better security than following generalized guidance.

This metric can be fine-tuned for specific industry unemployment and hiring conditions.

Underlying metrics:

  • Initial jobless claims (monthly average): A weekly measure of new unemployment benefit applications, serving as a key real-time indicator of labor market health.

  • Hiring rate: The JOLTS hiring rate is a monthly Bureau of Labor Statistics (BLS) metric that measures total hires during a month divided by total employment. It includes new hires, rehires, and temporary help additions, but excludes internal transfers or promotions.

  • U-6 unemployment: The broadest measure of labor underutilization, this rate includes officially unemployed individuals, marginally attached workers, and those employed part-time for economic reasons.

  • Long-term (27 weeks+) unemployment: The percentage of the total unemployed population that has been unemployed for 27 weeks or more. This duration marks the standard definition of “long-term unemployment.” 26 weeks of unemployment is the typical limit on non-emergency state unemployment benefits, although some states offer less.

These metrics are meant to offer a broad view of conditions in the labor market and measure changes that capture layoffs, growth in the underemployed population, and the pace of hiring.

  • Initial jobless claims: This measures the outflow from employment and serves as a high-frequency labor market indicator.

  • Hiring rate: This measures the inflow from unemployment back into the labor market.

  • U-6 & long-term unemployment: These are measures of stagnation in the labor market. A certain level of un/underemployment is not only normal but beneficial and enables fluid movement with the labor market. However, high levels of un/underemployment or excessively long periods of un/underemployment are damaging to the economy and particularly problematic for workers who become stuck in a disadvantaged position within the labor force.

Emergency Fund Resilience Index (Apr): 48.8

The Emergency Fund Resilience Index (EFRI) was largely unchanged (+0.1) from March, based primarily on offsetting conditions which lifted hiring but also increased overall unemployment. This month-to-month change is less important than the trend developing in 2026. Long-term unemployment and the hiring rate have improved, which will continue to benefit overall labor conditions.

The average monthly payrolls growth in 2026 is nearly double the pace over the first four months of 2025. However, the on-going disruptions and uncertainty from the high oil prices and rising goods prices may continue to weigh on consumers and businesses. These headwinds have the potential to put a damper on hiring throughout the summer if the Iran stalemate continues without adequate resolution.

The weak hiring rate in February snapped to the highest level since May 2024 in March. A drop back to the February lows will be the biggest concern for those in the labor market. At 3.3%, February was the lowest level since 2010. A lack of job growth and low layoffs in 2025 combined to create a scenario where there are few open positions for workers to step into. That logjam is loosening slightly as payroll growth increases, but its too early to declare victory. Workers still need to be prepared with a robust emergency fund to withstand many months of unemployment were it to happen.
