My Emergency Fund Is Too Big on Purpose. It's What Lets Me Be Honest at Work.

My Emergency Fund Is Too Big on Purpose. It's What Lets Me Be Honest at Work.

A few weeks ago I asked a question in a meeting that made it sound like I hadn't read the deck.

I had read the deck. That was the point. Everyone was three slides past a number that didn't make sense to me, and I put my hand up and said some version of "sorry, can we go back, I don't understand where this came from." There's a half-second where the room decides whether you're curious or just slow.

I do it a lot. Not because I'm brave, and definitely not because I'm the smartest person in any of those rooms. I do it because when I ask the dumb question, at least two other people exhale and one of them says "yeah, I was wondering that too." You're almost never the only one who didn't follow. You're just the one who admitted it.

The reason I can afford to be that person sits in a plain savings account and loses to the stock market every single year. My emergency fund is too big. I know it's too big. I keep it that way deliberately, and this is the article where I put a price tag on it.

What we actually hold, and how we landed on the number

At minimum, twelve months of essential household needs, in an instant-access savings account. Not a bond fund, not a brokerage account, not a credit line. A savings account.

We don't track it as a ratio. Once a year we open the tracker, look at what our high-level spending buckets actually averaged over the previous twelve months, and check the buffer still covers a year of the essential ones. Expenses move. A baby moved ours. So the target gets re-checked, and then we go back to ignoring it.

The bit most advice skips is that the number assumes both of us stop earning. Not one income going away while the other carries the mortgage. Both. My wife and I are reasonably confident we'd each find work again fairly quickly, and we sized the buffer as if we couldn't, because "you never know" is not a sophisticated risk model but it is an honest one. Neither of us talked the other into it. We both looked at the number and felt calmer, which is more or less how we make every money decision.

Which is the other thing. Almost everything written about emergency funds is written by and for one person optimizing one income. A household has correlated risks, uncorrelated ones, and two people who have to sleep next to each other after the decision.

The price tag, stated out loud

Here's the number the peace-of-mind crowd never puts in the article.

Horizontal bar chart comparing annual percentage returns: average euro-area household savings rate 0.28 percent, euro-area inflation 2.9 percent, best available instant-access savings account 3.75 percent, and long-run global equity return 7.39 percent, with the gap between the savings account and stocks marked as roughly 3.6 percentage points a year Data: ECB bank interest rate statistics (June 2026), Eurostat HICP (July 2026), CHECK24 (August 2026), MSCI ACWI net index factsheet (31 July 2026).

MSCI's All Country World Index has returned about 7.4% a year, net, since the end of 2000. The best instant-access account a euro-area saver can open right now pays around 3.75%. In Czechia the best spořicí účet is about 4.25%, which against our 1.3% inflation is a genuinely decent real return, and I want to be clear that's a temporary gift of the current rate regime rather than a permanent state of affairs.

So call it roughly three and a half percentage points a year, on the buffer only. That's the sticker price. I'm paying it.

The long version is worse. UBS's Global Investment Returns Yearbook tracks 1900 to 2025: a dollar in equities became $124,854, a dollar in Treasury bills became $69, and you needed $38 just to match inflation. Over 125 years cash roughly doubled in real terms while stocks multiplied by six figures. The optimizers are not making this up.

The version of the argument that went viral last year ran the math to about $800,000 of forgone growth over thirty years and framed a traditional emergency fund as a six-figure mistake. Worth knowing where that number came from: a Reddit thread. It's not a bad estimate, it's just not an analysis. I'd rather agree with the arithmetic and disagree with the conclusion than pretend the arithmetic isn't there.

One thing before anyone spends another evening arguing about allocation: go look at what your savings account actually pays. The average household overnight deposit in the euro area earns 0.28%, which is the ECB's own number, updated monthly. The best instant-access account pays 3.75%. The gap between the average account and a shopped-for one is the same size as the gap between a shopped-for one and global stocks. Half the cash drag everybody is philosophizing about is an afternoon of admin nobody has done.

Six months of expenses is a bet that you'll be average

Every institution says three to six months. MoneyHelper says it. Vanguard says it. Fidelity says it. Nobody can tell you where the rule came from, and I went looking. One organisation has quietly stopped saying it: the US Consumer Financial Protection Bureau's current emergency-fund page declines to give a month range at all, and says the amount "depends on your situation." Everyone assumes the regulator endorses three to six months. The regulator stopped.

Here's why that matters.

Horizontal bar chart of US unemployment duration in July 2026 showing 28.2 percent unemployed under 5 weeks, 29.5 percent for 5 to 14 weeks, 16.7 percent for 15 to 26 weeks, and 25.5 percent for 27 weeks or more, with the six-month mark highlighted Data: US Bureau of Labor Statistics, Table A-12, July 2026. October 2025 data was not collected due to the federal government shutdown.

In July 2026, 25.5% of unemployed Americans had been out of work for 27 weeks or more. A quarter of them, past six months. The median spell was 10.5 weeks and the mean was 24.9, and that spread is the whole story: the median doesn't ruin you, the tail does. Three-to-six-months advice is calibrated to the median.

Europe isn't gentler, just differently shaped. Roughly one in three unemployed people in the EU has been out of work for twelve months or more, and 16.5% for two years or more.

The tail also depends on your postcode, which is where I have to admit my own buffer is partly superstition. Praha and Střední Čechy have the joint-lowest long-term unemployment rate in the EU, 0.4%, tied with two Dutch regions. Cross into Slovakia and 42.5% of the unemployed have been out for two years or more. One border, a completely different correct answer. I live on the easy side of that line and still hold twelve months, which tells you this was never purely a risk calculation.

What a too-big emergency fund actually buys

Now the part every emergency fund article skips.

There's a term for this in the FIRE world, spelled politely as "f-you money," and it usually gets described as a destination. Something you arrive at near financial independence, after which you can finally tell your boss what you think of him. The best-known article on the concept is genuinely good on how it feels and contains, as far as I can tell, zero numbers.

I think that's backwards. F-you money isn't the finish line. It's one of the cheapest things on the menu, you can buy it years early, and what you get for it doesn't show up in your portfolio. It shows up in your career.

The evidence that money worry degrades how you work is better than I expected. The CIPD's 2025 survey of just over 5,000 UK workers found 31% saying money worries had hurt their work performance, and 13% saying it made it hard to concentrate or make decisions. The number that stopped me: among people earning £60,000 and above, it was still 22%. That's not a poverty finding. That's comfortable, well-paid people whose judgment at work is being quietly taxed by their own balance sheet.

Amy Edmondson's 1999 study of 51 work teams, the one that started the psychological safety field, defines it as a shared belief that the team is safe for interpersonal risk-taking. The behaviours she lists are exactly what I described at the top: asking for help, admitting errors, asking the question that might make you look incompetent. To be precise, because it would be easy to overclaim: Edmondson studied teams, not household balance sheets. That your savings account feeds into it is my extension of her idea, not her finding.

What is in the research is the negotiation literature. A 2019 study of "phantom alternatives" found that having a walk-away option changes what negotiators get, and the mechanism underneath it is perceived power. Not actual leverage. Perceived. Which fits what I feel exactly: the cash doesn't change the job market, it changes how I feel in the room.

You can watch the reverse effect at population scale. Bankrate's own term for 2025 was "job hugging." The share of workers planning to look for a new job fell from 56% in 2023 to 48%, the share planning to quit dropped from about 30% to 18%, and 62% said their pay hadn't kept up with expenses. More squeezed, less willing to move. That's what a room full of people who can't afford to say the true thing looks like from above.

Before I had a real buffer, I listened to the wrong people. "Don't bring that up here." "Not your fight." Nothing dramatic, no moment I'm ashamed of. Just a handful of meetings where an honest question might have changed something, and I let it go, and nobody else asked it either, and we all went to lunch.

The honest limit of my own argument

The strongest objection to all of that is: it's job security that buys workplace honesty, not cash, and speaking up gets people fired regardless of what's in their savings account.

I can't beat that with data. Retaliation has been the most-alleged charge type filed with the US EEOC for seventeen consecutive years. Being able to survive financially is not the same as being safe.

So here's the smaller, truer claim: the cash doesn't stop you getting fired for asking the question. It changes what happens the next morning. That's the whole product.

I should also admit the cognitive-bandwidth research everyone quotes here is contested. The famous 2013 Science paper found financial worry costs poor participants roughly the equivalent of a lost night's sleep, and it's been challenged hard: a comment in the same journal showed the effect vanished when income was treated as continuous rather than split at the median, and a large 2016 field study found no difference in cognitive performance before and after payday. I lean on the CIPD self-reports and my own experience, not that paper.

And by conventional logic, twelve months for a two-income household in two different industries is over-insurance. Two uncorrelated incomes are already a diversification strategy, arguably a better one than cash. I'm not claiming this is optimal. I'm claiming it's worth it, which is a different sentence.

Why it's a boring savings account and nothing cleverer

The standard rebuttal is that the buffer should live somewhere productive. A taxable brokerage account. Short-term bond ETFs. A home equity line of credit. Margin against your portfolio.

Every one of those has a documented failure mode, and they all fail at the same time. In 2008 Countrywide suspended an estimated 122,000 home equity lines, and the Federal Reserve eventually published consumer guidance because homeowners across the country were finding theirs frozen or reduced. FINRA spells out that securities-backed lines of credit are demand loans, callable at any time, and if your collateral drops the firm can sell your securities. The MSCI ACWI's worst drawdown was 58.4%, October 2007 to March 2009. Your liquidity plan and the crash arrive on the same morning.

There's a second reason. That whole playbook is American. HELOCs in the US sense barely exist across most of continental Europe, the Czech "americká hypotéka" is a different product on different terms, and the tax treatment that makes selling from a brokerage account cheap is jurisdiction-specific. A plain instant-access savings account is the only instrument in this argument that works identically in Brno and in Boston.

The ratio is supposed to shrink

Here's the part that makes the whole thing bearable, and I wish someone had told me at the start.

When you're building your first buffer, it's 100% of what you have, which feels awful if you've read anything about compounding. But once it exists and you stop feeding it, the buffer is fixed and everything else keeps growing. As a share of your net worth it gets smaller every year without you doing anything.

That's why I never think about it as a percentage. The cash number is anchored to our life, the rest of the balance sheet is anchored to the market, and the ratio takes care of itself. If yours feels like it's swallowing your whole portfolio, that's a stage, not a permanent state. Same logic as coasting: the pile does the work once the pile is big enough.

Obvious caveat: this is written for people who can choose. Thirty percent of EU households say they couldn't face an unexpected expense at all, and in Czechia it's 19.2%. For most of them this isn't an allocation debate, it's an income problem, and I wrote about that side of it separately. If you're there, the cash-drag argument is a luxury problem and none of this is aimed at you.

The emergency fund we've never used

Not once. Thank god.

Every time we've wanted something big, we saved for it separately, on top, in its own pot. The emergency fund is for emergencies. Not a car, not a stroller, not a holiday. Actual emergencies, when they arrive.

Which means that on paper this has been a pure cost for years. Several percentage points a year, compounding against me, buying nothing measurable.

Except I keep asking the dumb question in the meeting. I've never taken a role I didn't want because I needed money by a specific date. I've never had to treat staying or moving as a financial emergency rather than a career choice. That's what I've been buying, and I don't know how to put it on the chart.

If you want to check your own number, the boring version takes twenty minutes: pull twelve months of statements, work out what your essential monthly spend actually is rather than what you think it is, multiply, compare. I do it in the tracker I build, which is my own product, so weigh that accordingly. A spreadsheet does the same job.

Then go and shop your savings rate, because 0.28% is embarrassing and it's costing you about as much as the argument you were about to have with a stranger on the internet.
