Latest / The Emergency Fund Podcast with Fexingo: Cash Reserves, Saving, and Financial Cushion / When Your Emergency Fund Needs More Than Three Months
Transcript
- Lucas: So we all know the rule. Three to six months of expenses in an emergency fund. It's practically engraved on the first tablet of personal finance. Luna: Right, I've heard it so many times it almost feels like a law of nature. But it never quite sat right with me. Lucas: That's because it's a heuristic, not a law. And heuristics break when your situation doesn't match the median salaried worker. I want to look at one specific case today: people whose income fluctuates month to month. Luna: So freelancers, gig workers, small-business owners, commission-based sales — anyone where the paycheck isn't a fixed direct deposit every two weeks. Lucas: Exactly. And if you look at the data from a 2025 study by the Freelancers Union, the median freelancer saw income swing by forty percent month over month at least twice a year. That's a huge gap to cover with a static emergency fund. Luna: Forty percent — so if your average month is five thousand dollars, you could have a two-thousand-dollar shortfall some months. That's not a minor bump. Lucas: It changes the whole calculation. The standard three-month rule assumes you can predict when you'll need the money. But for a freelancer, the need isn't a one-time job loss — it's a recurring pattern of lean months. Luna: So what do you do instead? Just pile up twelve months of expenses? Lucas: That's one answer, but it's capital-inefficient. You're leaving a lot of money earning zero or near-zero return. I think a better approach is to calibrate your emergency fund to your actual income volatility, not some generic multiple. Luna: How do you measure that? I track my income, but I've never calculated volatility formally. Lucas: You can do it with a spreadsheet in about ten minutes. Pull up your last two years of monthly income. Find your worst two consecutive months — the lowest total over a sixty-day window. Then subtract that from your average two-month income. The difference is your typical drawdown. Luna: Okay, so for me, if my average two months is ten thousand, and my worst two months were, say, six thousand total, then my drawdown is four thousand. Lucas: Right. That four thousand is the minimum cash buffer you need to smooth out your worst normal period. Then you add a cushion on top for actual emergencies — a car repair, a medical bill, a client who doesn't pay on time. I'd add another fifty percent of that drawdown number, so in your case, six thousand total. Luna: That's more than three months of expenses for me, but it's not an arbitrary number — it's tied to my actual history. I like that. Lucas: And if your income is seasonal, you might have a predictable lean quarter every year. Then you can build a reserve ahead of that quarter and let it run down, then rebuild. That's more of a planned buffer than a static emergency fund. Luna: Where do you park this cash? Because if it's six thousand dollars, I don't want it in a checking account earning nothing, but I also can't afford to have it drop twenty percent in the stock market. Lucas: Right now — mid-2026 — you can get around four and a half percent in a high-yield savings account. That's not nothing, and it's FDIC insured. For the portion you're confident you won't need for at least three months, a short-term Treasury bill or a three-month CD ladder can bump that yield a little higher. Luna: A CD ladder for an emergency fund sounds complicated. Is it worth the hassle? Lucas: For small amounts, probably not. If your buffer is under ten thousand, a high-yield savings account is fine. But if you're holding twenty or thirty thousand, you can ladder three-month CDs so one matures every month. That gives you monthly liquidity and a slightly higher rate. Luna: Makes sense. So the key is matching the liquidity to the timing of your potential income gaps. Lucas: Exactly. And that's the deeper point — the emergency fund isn't one size fits all. It should be a personalized liquidity tool, not a rule of thumb you heard on a blog. Luna: I think a lot of people also forget to revisit the number. I set my fund three years ago and haven't touched it, but my expenses and income have changed. Lucas: That's a great point. I'd recommend recalibrating every twelve months, or any time you have a major life change — marriage, a new business, a move to a higher-cost city. Luna: What about the psychological side? Having a larger cash buffer feels secure, but some people worry they're missing out on investment returns. Lucas: That's the classic opportunity cost argument. But the purpose of an emergency fund isn't to maximize returns — it's to prevent you from having to sell stocks at a loss when you need cash. That's a form of insurance, and insurance costs money. Luna: Right, you're paying a premium in forgone returns for the option to access cash without triggering a taxable event or a portfolio loss. Lucas: Bingo. And for people with volatile income, that insurance is more valuable, not less. Your worst-case scenario isn't a one-month job search — it's a six-month income drought. The standard advice doesn't model that. Luna: So if someone's listening and they're self-employed, what's the one number they should calculate today? Lucas: Your personal drawdown ratio. Take your worst two-month income total over the last two years, divide by your average two-month income, and subtract from one. That gives you the percentage drop. Then multiply that by your average monthly expenses to get your dollar buffer target. Luna: I'm going to do that tonight. I bet my number is higher than I think. Lucas: And that's fine. Better to know the real number than to cross your fingers and hope three months is enough.

Lucas: Yeah, we don't run ads — that's a deliberate choice. Listener support is what keeps these conversations going. Luna: So back to the numbers — what about people who have a stable salary but high expenses? Should they still use the income-volatility method? Lucas: If your income is stable, the traditional expense-based approach works fine. But I'd still encourage you to stress-test it. Ask yourself: what's the worst-case scenario for your industry? If you're in tech and you saw the layoffs in 2023 and 2024, you know that even stable jobs can vanish quickly. Luna: So you're saying the three-month rule might be too low even for salaried workers in volatile sectors. Lucas: Exactly. I've seen data from the Bureau of Labor Statistics showing that the average duration of unemployment for tech workers in 2024 was over five months. If your emergency fund only covers three, you're in trouble. Luna: That's sobering. So maybe the rule should be: three months as a floor, but calibrate up based on your industry and income variability. Lucas: That's a better heuristic. And for the self-employed, I'd say six to nine months of essential expenses is a reasonable target. But again, do the math on your own data. Luna: One thing I've wondered: does it make sense to use a Roth IRA as a backup emergency fund? I've heard people suggest that. Lucas: It's a controversial strategy. You can withdraw contributions from a Roth IRA anytime tax-free and penalty-free. But the problem is you're raiding your retirement savings. If you do that once, you lose decades of compound growth on that money. Luna: So it's a last resort, not a first line of defense. Lucas: Exactly. I'd only consider it if you have a very high income and you're already maxing out retirement accounts. For most people, a dedicated cash reserve is cleaner. Luna: Alright, so to wrap up: the emergency fund should be personal, based on your income history and industry risk, not a generic rule. And keep it in something liquid and safe. Lucas: And revisit it every year. Your life changes, your fund should too. Luna: Thanks, Lucas. Good conversation. Lucas: You too. Take care.
