What does it mean when people say you need 3-6 months of expenses saved up?

Hey everyone, I’m a 23-year-old guy who just graduated college and landed my first full-time job. I’ve been investing for a while now, but I’m new to some of these adulting things like budgeting and building an emergency fund. I keep hearing you need to have 3-6 months of expenses saved as a ‘cushion,’ but I’m not totally clear on what that really means.

When it comes to risk, I don’t love the idea of leaving that much money in a regular savings account because it hardly earns anything. I’m considering putting it in something like SPAXX, which has low risk and earns about 5%. But would it be too risky to go even further, like with an ETF such as SCHD?

Also, what about liquidity? I figure if there’s an emergency, I could probably use my credit card to cover things until I can transfer money from SPAXX, even if it takes a day or two. But is it smart to keep maybe a month’s worth of expenses in a regular savings account for quicker access?

And finally, how do you all decide between 3 months vs. 6 months? Thanks a lot for any insights!

Edit: No idea why this is getting downvotes, but I appreciate everyone’s replies so far.

Figure out what your monthly essential expenses are - rent, car payments, food, etc. Add it up, then multiply by 3 or 6 for a bigger cushion.

Keep that money in a high-yield savings account where it’s safe and easy to access. Think of it like a safety net. Life can throw a curveball - losing a job, getting hurt, or a family emergency. That’s what this fund is for.

It’s there to catch you when life gets tough. Not for day-to-day expenses.

@Wei
Your safety net can also be a line of credit. If you have access to a credit line for 6 months’ worth of expenses, you can use that.

I had an emergency fund for about a year, but now I just use margin from my investment account. My 6-month cushion is around $25k, and I can get that amount in my checking within an hour if I need it.

@Noah
Original poster, this sounds risky! If the market or this guy’s stocks tank, he gets margin called and might have to sell his investments fast.

An emergency fund is supposed to be stable. You don’t want it tied to the stock market’s ups and downs.

@Dru
Yeah, my gut was telling me this wasn’t the best approach for a rainy day fund lol

@Dru
So your emergency plan is … credit card debt? :face_with_raised_eyebrow: Good luck with that!

What’s the problem? I have a $100k limit across my credit cards and about $100k in my investments. If something goes wrong, I’d have time to cash out my investments to cover my card bill.

I usually pay off my credit cards each month anyway. Works well for me!

But what if ‘something going wrong’ means your investments tank? That’d be rough.

I’m not too worried. Not all of my investments are in stocks like VOO. I have a portion in safer funds like BOXX SPAXX and SGOV.

This is not a real emergency fund… This plan could easily backfire, potentially leading to bankruptcy.

It’s just a numbers game; not always black and white.

If you have a $500k brokerage and only need a $25k emergency fund, you’re pretty safe even if the market takes a big hit.

@Noah
Here’s the simple version:

If you want a reliable emergency fund, don’t base it on debt or stocks. Just save the money.

Having some cash in the bank is always smart. Sometimes you’ll find a place that only takes cash, or an ATM nearby goes down.

Exactly, that’s why I keep a small emergency stash in a local checking account just in case.

@Kip
He’s talking about using high-interest debt as a safety net, though. Not great advice.

To put it differently - if you’re well-invested, a smaller cash fund can work. As long as you have a safety plan, like credit as a bridge while you access funds, it’s workable.

@Kip
But depending solely on credit cards as a backup for your emergency fund? Doesn’t seem wise.

@Noah
This kind of emergency fund approach is super risky because you’re relying on credit. If your income stops and you can’t pay your bills, some payments (like rent) might not even be payable by credit. Plus, interest rates on credit debt can be brutal.

@Noah
You can’t use a credit card for everything, like rent or car payments.

A mix of cash and credit might be okay, but relying totally on credit is really risky.

@Noah
This plan feels way too messy for an emergency fund!
