How Much Should You Have in an Emergency Fund, and Where Should You Keep It?

A real emergency fund has two parts, not one: enough cash to replace your income for a set number of months, plus a separate reserve sized to your own track record of things breaking. Most people fund the first part, skip the second, then wonder why the account is empty before they ever lose a job.

Here is the version of this I live on my end of the phone. A client needs money. Not next quarter. This week. Water heater, transmission, emergency root canal, roof. And the only place it can come from is the portfolio we spent two years building.

Why does not having an emergency fund cost more than the emergency itself?

Because the emergency gets paid for by selling investments, and you do not get to pick the day.

If the market is down that week, we sell at a loss the client never chose to take, and a decline that lived on a statement becomes real. If the market is up, we sell something they wanted to hold and hand a slice to the IRS in a year nobody budgeted for. Either way it is a sale neither of us would have picked, made on a schedule set by a plumber.

That is not a market problem. It is a cash problem wearing an investment costume.

I spent years standing post at embassies overseas. Standing post is being fully ready for the night when nothing happens, which is almost every night. That is the entire job description of an emergency fund. It sits there doing nothing, looking like dead money, right up until the one night it is the only thing between you and a bad decision.

There are also mechanical costs to a forced sale that clients rarely see coming:

In a taxable brokerage account, selling creates a capital gain or loss for that tax year. A gain you did not plan for can move your tax bill and, depending on your situation, other income-tested amounts.
Sell at a loss and buy substantially identical stock or securities within 30 days before or after, and the wash sale rules generally disallow the loss for that year. The disallowed amount is generally added to the basis of the replacement shares, so the loss is deferred rather than erased. One trap is worth knowing: buy the replacement inside an IRA or Roth IRA and the loss is disallowed with no basis increase, which means it is gone for good.
Selling inside a retirement account does not trigger tax by itself. Taking the money out often does. Distributions from a traditional IRA or traditional 401(k) are generally taxed as ordinary income to the extent they are includible in income, and under age 59 and a half a 10 percent additional tax may apply unless an exception fits. Qualified Roth distributions work differently, and the exception lists are not the same for IRAs as they are for employer plans. The account type matters.

An emergency fund does not make you money. It buys you the right to choose when you sell. Over a long enough stretch that is worth more than the yield.

How many months of expenses should an emergency fund cover?

Start at three months of essential expenses. Treat three as the floor, not the goal, then add months for anything that makes your income harder to replace.

Three months sounds generous until you look at how long people actually sit. For June 2026, seasonally adjusted, the Bureau of Labor Statistics put the median duration of unemployment at 11.0 weeks. Fine, three months clears that. But among people unemployed that month, the average time out so far was 25.5 weeks, and 1,937,000 of them, 27.3 percent of everyone unemployed, had been looking for 27 weeks or longer.

So three months gets you through the middle of the pack and leaves you standing in the rain with better than a quarter of that statistic.

Step one. Total your monthly essential expenses. Housing, utilities, groceries, insurance premiums, transportation, minimum debt payments, childcare, prescriptions. Not restaurants, subscriptions, travel, or gifts. Those get cut in week two of a real job search, which is exactly why they do not belong in the number.

Step two. Start at three months and adjust. This table is a planning illustration, not a recommendation. It is built to start a conversation, not replace one:

Factor	Adjustment
You are the household's only earner	Add 1 month
Your income is variable (commission, bonus-dependent, self-employed, 1099, tips)	Add 1 month
Other people depend on your income	Add 1 month
Your role is senior or specialized enough that a local search runs longer than average	Add 1 month
You are 55 or older and still working	Add 1 month
You own your home	Add 1 month
Two stable incomes, and either one alone covers essential expenses	Subtract 1 month

Step three. Multiply. Monthly essential expenses times your adjusted month count.

Three months stays the floor no matter what the adjustments produce. Many planners treat something around twelve months as a practical ceiling, and if your number lands well past that you are solving a different problem. A planned career change, a sabbatical, or a business exit is a funding goal with a date on it. That belongs in its own plan, not stuffed inside an emergency fund.

Should you size an emergency fund off your salary instead of your expenses?

Use expenses if you track them. If you do not, use take-home pay. Never gross salary.

Gross is the wrong input, and it is wrong in an expensive direction. It includes federal and state withholding, payroll taxes, and retirement contributions you will not owe on income you are not earning. The government took its cut before that money ever reached you, and it is not issuing a refund because you got laid off. Size a fund off gross and you inflate the target by roughly the share of every paycheck you never see.

Take-home pay is a workable stand-in. Multiply net monthly pay by your adjusted month count. That figure will overstate what you actually need, because take-home includes the discretionary spending you would cut anyway. Treat it as deliberately conservative. When you eventually sit down and total real essential expenses, the target usually drops.

How do you use your own history of emergencies to size the second bucket?

Look back 36 months and let your own record set the number. Not a national average. Yours.

There is a line in the military about redundancy that has stuck with me: two is one, one is none. It applies to gear and it applies here. A fund built only for job loss has exactly one job, which means the first surprise that is not a job loss takes it apart.

And those surprises are not politely waiting for you to be unemployed. The water heater goes while you are fully employed. So does the crown, the transmission, and the deductible. Each one takes a bite, nobody refills the account, and by the time an actual income interruption shows up the fund is a rumor.

Step one. List every unplanned expense over $500 in the last three years. Home and auto repairs, medical and dental, veterinary emergencies, insurance deductibles you actually paid, emergency travel for a family illness or funeral.

Step two. Total them, divide by three. That is your annual surprise-expense rate, measured on your house, your cars, your health. Not a survey.

Step three. Separately, add your insurance deductibles plus your health plan's annual out-of-pocket maximum. That is your worst realistic single year.

Step four. Your expense shock reserve is the higher of the two.

Total fund equals bucket one plus bucket two. Someone with $4,000 in monthly essential expenses, five adjusted months, and a $6,000 expense shock reserve is looking at $26,000, not $20,000. That $6,000 gap is the entire reason people who believe they have an emergency fund still end up calling me to sell something.

If you have owned your home under three years, or just moved into an older one, your lookback understates what is coming. Lean on the deductible-plus-out-of-pocket figure until you have your own history.

What does an emergency fund actually cover, and what does not belong in it?

It covers events that are unpredictable in timing and involuntary in nature. That is the whole test.

Things it is for:

Job loss, furlough, cut hours, a delayed paycheck
Medical and dental costs, including deductibles and out-of-pocket maximums
Home systems that quit without notice: HVAC, roof, water heater, plumbing, electrical, foundation
Repair or replacement of the vehicle that gets you to work
The waiting period before disability insurance starts paying
Emergency travel for a family illness or death
Temporary housing and immediate costs after a storm, fire, or flood
Veterinary emergencies
An unexpected legal bill

Things it is not for:

Property taxes, insurance premiums, tuition, annual dues. These arrive on the same date every year. That is not an emergency, that is a calendar.
A roof you already know needs replacing in two years. That is a sinking fund with a deadline.
Vacations, weddings, holidays, and cars you are choosing to upgrade.
A house down payment.
An investment opportunity. Cash earmarked for opportunity is a different account with a different job.

This distinction matters more than it sounds like it should. A common reason an emergency fund comes up short is not that it was sized too small. It is that the same account was quietly moonlighting as the vacation fund, the property tax fund, and the new-furniture fund, so it was already half spent when the real thing arrived. Give known expenses their own accounts and leave the emergency fund alone.

For what it is worth, this gap is normal rather than unusual. In the Federal Reserve's most recent Survey of Household Economics and Decisionmaking, fielded October 17 to 28, 2025, 55 percent of adults said they had set aside money for three months of expenses in an emergency savings or rainy day fund if they lost their primary source of income. Sixty-three percent said they would cover a hypothetical $400 emergency expense exclusively using cash, savings, or a credit card paid off at the next statement. Twelve percent said they could not pay a $400 expense by any means.

Read that last number twice. Four hundred dollars.

What changes if you are married and both of you work?

Two incomes do not mean half the emergency fund. Size it to the hole one job loss leaves, not to half of household expenses.

Find the actual hole. Take monthly essential expenses, subtract the other spouse's net monthly income. What is left is the monthly shortfall a single job loss creates. Multiply that by your adjusted month count.

Run it twice. Once for each spouse losing their job, then fund the larger number. In most households those two figures are not close, because the two incomes are not equal.

Three things dual-income households routinely miss:

Correlated income is not diversified income. Same employer, same industry, or same dominant regional employer means one event can take out both paychecks. In that case treat the household as single-income and skip the one-month reduction. Two paychecks from the same source is one paycheck with extra steps.

Whoever carries the health coverage carries extra risk. If the spouse whose employer provides family health insurance loses that job, the household loses income and coverage on the same afternoon. Price COBRA continuation or marketplace coverage for your actual family and add several months of that premium to your expense shock reserve. For a lot of families it is one of the biggest line items in the whole calculation, and it is the one people discover afterward instead of before.

Fixed costs scale with the second income. Two earners usually means a mortgage sized to two incomes, two vehicles, and childcare that continues through the job search because you need to be free to interview. Essential expenses do not fall by half when one income stops. Often they barely move.

Net effect: a two-income household can usually carry fewer months than a single earner, but the dollar target does not drop nearly as much as the month count suggests.

Where should you keep an emergency fund?

Somewhere you can reach in a day or two, separate from checking, and not invested in stocks.

The military plans communications with a PACE plan: primary, alternate, contingency, emergency. You set the order before you need it, so nobody is inventing a plan under stress with the clock running. Cash works the same way. Most households have one line and no backup.

One way to order it. Primary is checking, holding a little. Alternate is an insured savings or share account you can hit same-day. Contingency is a money market fund or high-yield savings carrying the bulk. Emergency is the portfolio, and the entire purpose of the first three is that you never reach E.

Those conditions rule out more than people expect. They rule out the brokerage account, which is the point. They also rule out leaving it in everyday checking, where money gets spent without anyone deciding to spend it.

Here is what published rates looked like recently:

Product	Rate	As of
Regular savings account, banks, national average	0.32%	December 26, 2025
Regular savings account, credit unions, national average	0.19%	December 26, 2025
Money market account, banks, national average	0.52%	December 26, 2025
Money market account, credit unions, national average	0.74%	December 26, 2025
13-week U.S. Treasury bill, bank discount basis	3.81%	July 24, 2026
13-week U.S. Treasury bill, coupon equivalent	3.90%	July 24, 2026

Park $20,000 in a bank savings account at that 0.32 percent national average and you have earned about $64 for the year. Sixty-four dollars. That is the going rate for the word "savings."

Now three caveats, because it is genuinely easy to draw the wrong conclusion from that table and I would rather you draw the right one.

These are not measured on the same date. The deposit rates come from the NCUA's quarterly comparison of bank and credit union rates, reflecting rates reported for December 26, 2025, which was the most recent edition published as of this writing. The Treasury figures are from July 24, 2026. Both markets moved in between. The distance between the two halves of that table is not a clean same-day spread.

They are not measured on the same basis. The deposit figures are national averages of posted rates at a $2,500 balance tier. A Treasury bill's bank discount quote uses a 360-day discount convention and is not an annual percentage yield. The coupon equivalent is the closer comparison and still is not an APY. Comparing a posted deposit rate to a bank discount quote overstates the gap.

A national average is not your bank. Plenty of banks and credit unions pay well above the average on high-yield savings. The only number that matters is the one your institution is paying you, and finding it takes about two minutes.

What the Treasury line is doing in that table is showing the kind of instrument a money market mutual fund holds. The SEC describes money market funds as investing in high-quality, short-term debt securities, and describes government money market funds as investing 99.5 percent or more of total assets in very liquid investments including cash, government securities, and repurchase agreements collateralized fully with cash or government securities. Because of what sits inside them, a money market fund's yield tends to track short-term interest rates rather than a bank's posted deposit rate. The SEC's own wording: the yield of money market funds changes over time and generally reflects changes in short-term interest rates.

That is a structural difference. It is not a promise about which one pays more on any given Tuesday.

What are the trade-offs between a money market mutual fund and a bank or credit union savings account?

Insurance and yield are the two axes, and they point in opposite directions. Decide which one you are buying.

Bank and credit union deposit accounts are federally insured. The FDIC's standard insurance amount is $250,000 per depositor, per insured bank, for each account ownership category. The NCUA's Share Insurance Fund insures individual accounts at a federally insured credit union up to $250,000, insures a member's interest in all joint accounts combined up to $250,000, and separately protects IRA and Keogh retirement accounts up to $250,000. Two things worth checking. Not every credit union is federally insured, since some state-chartered institutions carry private insurance that is not backed by the full faith and credit of the United States. And the NCUA does not insure money in stocks, bonds, mutual funds, annuities, life insurance, or municipal securities, even when those are sold by a financial advisor located at a federally insured credit union. Deposit money is available immediately. The rate is set by the institution and can change whenever the institution decides to change it.

Money market mutual funds are securities, not deposits. The SEC states that money invested in a money market fund, like money invested in any mutual fund, is not guaranteed by the FDIC the way bank accounts are, and that there is a risk you may lose some or all of the money you invested. Specifics that matter:

The share price can move. Retail and government money market funds seek to hold net asset value at a stable $1.00 per share. Institutional prime and institutional tax-exempt funds are not permitted to use those pricing conventions and must float their NAV. If a stable-NAV fund's NAV per share deviates by more than half a cent from $1.00, the fund must reprice its shares. That is called breaking the buck, it happens very rarely, and if it happens the holding loses value.
The yield is not fixed and carries no promise. It moves with short-term rates. A rate that looks good today can fall.
Fees can exceed income when rates are very low. The SEC notes that if short-term interest rates are very low, it is possible that fees charged by the fund will exceed the income earned on fund investments, in which case fund investors may face losses.
Inflation risk is real. The SEC also notes that because the yield for money market funds can be low, there is a risk that inflation will outpace and erode investment returns over time.
Liquidity fees work differently by category, and the category is not a detail. All money market funds are permitted to charge a liquidity fee. Retail prime and retail tax-exempt funds must charge one if the fund's board or its delegate determines a fee is in the fund's best interest. Institutional prime and institutional tax-exempt funds are additionally required to charge one when daily net redemptions exceed 5 percent of net assets, unless the fund's liquidity costs are de minimis. Government money market funds are not subject to either requirement. If you are holding cash you may need on short notice, know which category you own.
Access takes a step. Proceeds have to settle, then move to a bank account. Settlement timing varies by fund, so check the prospectus for the specific fund instead of assuming. That is fine for a $6,000 HVAC replacement. It is not the account you want your debit card pulling from at a gas station.

One structure some households use is a small amount in checking, a federally insured deposit account for whatever they might need same-day, and the remainder in insured high-yield savings or a money market fund depending on their tax situation and how fast they would realistically need the money.

Which of those fits depends on facts specific to you. Nothing here is a recommendation to buy, sell, or hold any particular product, and a money market fund should not be purchased without reading the fund's prospectus, including its objectives, risks, charges, and expenses.

Does any of this look different in Houston or Richmond?

The formula is identical. The inputs are not, because what breaks is regional.

Houston. In Texas a homeowners deductible may be a flat dollar amount or a percentage of the home's insured value, and policies commonly carry a separate deductible for windstorm damage. According to the Texas Office of Public Insurance Counsel, named storm deductibles are usually much higher than other policy deductibles, and not all policies contain a named storm deductible at all. Translation: the number you would actually write a check for after a hurricane may look nothing like the deductible you have in your head.

In the Marine Corps we ran pre-combat checks. You inspect the gear before you need it, not while you are using it, because the middle of the event is the worst possible moment to discover something is missing. Pulling your declarations page and finding your real windstorm or named storm deductible is a pre-combat check. Do it in May, not while you are watching a cone graphic on the news. Then put that real number into your expense shock reserve.

Flood is separate. The Texas Department of Insurance states that homeowners policies do not cover damage caused by floods, so flood coverage has to be bought on its own. And sitting outside a mapped high-risk flood area is not the same as being safe. FEMA reports that for 2014 through 2024, nearly one-third of National Flood Insurance Program claims, 29 percent, came from areas located outside current high-risk flood areas. Foundation movement on clay soil and freeze-related plumbing damage round out the local menu, and none of it is cheap.

Richmond and Glen Allen. Ice and winter storm damage, older housing stock with systems well past their prime, and a labor market where a meaningful number of households depend on federal employment or federal contracting. For those households an interruption in federal appropriations is not an abstraction, it is a cash-flow event with a date on it. During the federal lapse in appropriations that ran October 1 through November 12, 2025, household survey data for the October 2025 reference period were not collected and were not collected retroactively, so no October 2025 unemployment rate exists. Payroll survey data for October 2025 were collected and published later. The practical lesson for anyone whose paycheck runs through an appropriation is that a reserve built to bridge a pay interruption is a recurring need, not a hypothetical.

How do you build the fund without derailing everything else?

Automate a fixed transfer on payday and route irregular money to the fund until it is full.

The transfer leaves your checking account the day you get paid, not at the end of the month when it has to compete with whatever is left. Size it so you do not have to think about it, even if that means a smaller number and a longer runway. A fund built slowly and left alone beats a fund built fast and raided twice.

Irregular money is where real progress happens. Tax refunds, bonuses, the month you finish paying off a car. Each one is a decision point. Sending a fixed share of every one to the fund until it is full gets most households there faster than raising the monthly transfer ever will.

Two practical notes. Keep it at a different institution than your checking account if you tend to spend what you can see, because the extra day of friction is a feature. And when it is full, stop. An emergency fund is supposed to be adequate and boring, not perpetually growing. Money piling up past your target is money without a job, and giving it one is a separate conversation worth having on purpose rather than by accident.

Frequently asked questions

How much should I have in an emergency fund? A common starting framework is three months of essential expenses as a floor, plus a month for each factor that makes your income harder to replace, plus a separate reserve equal to the higher of your average annual surprise expenses over the last three years or the sum of your insurance deductibles and your health plan's out-of-pocket maximum. Your own number depends on your income stability, your obligations, and your household structure.

Is a money market mutual fund a good place for an emergency fund? It can be a reasonable home for the portion you would not need the same day, because its yield generally tracks short-term interest rates. It is not guaranteed by the FDIC, its share price can move, and its yield can fall, so it is not equivalent to an insured deposit account. Whether it fits depends on your situation.

Do money market mutual funds pay more than a savings account? Sometimes, and sometimes not, and the honest answer requires care with the comparison. The most recently published national average rate on a regular bank savings account, from December 2025, was 0.32 percent, while the 13-week Treasury bill was quoted at 3.81 percent on a bank discount basis on July 24, 2026. Those figures come from different dates and are calculated on different bases, so the difference between them is not a clean spread. Yields on both change constantly, and some high-yield savings accounts pay well above the national average.

Should a married couple with two incomes keep less in an emergency fund? Usually fewer months, but not proportionally fewer dollars. Size the fund to the shortfall left after subtracting the other spouse's net income from essential expenses, run the calculation for each spouse, and fund the larger figure. If both incomes come from the same employer or the same industry, treat the household as single-income.

Should I keep an emergency fund if I still have credit card debt? Many households benefit from building a small reserve first, because without one the next surprise expense goes right back on the card and the balance never actually falls. The right balance between paying down debt and building cash depends on your interest rates, your income stability, and your other obligations, which is worth working through with an advisor.

Where should the emergency fund live if I am worried about spending it? At a different institution than your checking account, with no debit card attached. The short delay in moving money is a feature, not a flaw, because very little that genuinely qualifies as an emergency has to be paid inside the hour.
