Going to be needing to buy kid a vehicle in about a year.

Why wouldn’t you do a 401k loan? Genuine question…

Yes you lose growth, but you are recouping some of that thru the interest you are paying yourself…correct?

So if your portfolio is getting 10% return, and you are paying 7% interest, you are only losing out on 3%..

Am I understanding this correctly?

IDK about all the specifics, but I just view that money as money that I don’t wanna touch. Like I’m gonna need it when I’m too old to work .

I’d rather just take out a car loan on a used car.

That’s how I’ve always felt… but you are paying yourself back, with interest…

So you still have it when you retire…

So I guess it’s a gamble if your return minutes the interest rate is lower than the rate you would get in a traditional loan.

For one thing the interest you pay yourself is taxed on your paycheck and yet usually goes into pretax bucket. So it gets double taxed.


Yes it can be an easy place to borrow money and it doesn’t go on your credit report. But if you leave your job you can be screwed by the loan becoming taxable (and maybe penalties if under 59.5).

If your retirement savings are already lower it can screw your long term savings.

You stipulated that you want to be talked out of a 401k loan.

401k is retirement savings.

Buying a vehicle is not retirement savings.

If your kid is old enough to drive and wants a vehicle, the kid and you can find a way to fund it without destroying your future.

Don’t do it.

Don’t set yourself back on compounding interest. It’s always a bad idea.

Taking $20,000 from your 401k now is going to be equal to taking away $100,000 or more from your 401k in 20 years. It removes a shite ton of compounding ability long term.

Vehicles are depreciating assets. If you are going to take a loan on anything at least make it be something that will hold its value.

This right here. You are paying yourself back with after tax money, but it is going into your pretax 401K, so you will then have to pay taxes when you withdraw that money in the future.

Double taxed

i am all for 401k loans if you know how to work the system. It is even better if you have a solo401k because i get the interest rate i want.

but for this is just dumb.

business investment? great. for a damn car? F no.

just get a car loan if you cannot pay cash.

Because if you ever start viewing retirement assets like a 401k as "available" (before you start taking it), you'll never reach your retirement age with enough money to live on.

Money borrowed from your 401(k) stops earning compound interest and market gains. Even if you repay it, you’ve missed out on potential growth during that time—especially if the market performs well. You repay the loan with after-tax dollars. Later, when you withdraw in retirement, you’ll pay taxes again on that same money.

Use 401k contributions only as a last resort unless you're "boxed in" and have no other alternatives. That'd go for all retirement assets (unless maybe you had a ROTH IRA, but then it's the same principle, although that'd not be a taxable event.)

Alternatives if possible:

1st...Manage expectations. Set a budget. A "vehicle" doesn't need to be a $50k Dodge Charger R/T! Our kids first cars were our old Toyota Avalons. Safe. Reliable. Worked just fine at that point. Any used cars in the family you could use or buy?

Dealer options? They may offer 0% APR or rebates on certified pre-owned vehicles.

Don't favor using loans for depreciable assets like a car. Instead, if your timeline is "about a year", could you start a dedicated auto fund now in a high-yield savings account or short-term CD?

Not enough time? Then look into maybe a Home Equity Line of Credit (HELOC), which go for around 6-8%.

I second this. If you are really considering paying full price with a 401k loan, also consider making a smaller loan for a down payment and co-sign an auto loan for your son so he can learn fiscal responsibility and establish his credit score.

Also - depending on your 401k plan's loan rules, taking a loan may affect your ability to get another loan for a true emergency, and also affect the max amount of your next loan. Learn those details before making a decision.

Don't you pay that loan back through your normal 401K contributions? If so, then you also sacrifice what could be a few years of contributions.

My parents couldn't afford a car for me, or themselves for that matter, so I had to work it out myself. It won't kill him, and you can still help him do that.

I have had to take out several 401K loans years ago. I paid each one of them back, but believe me you should not touch it unless its a last resort. It was an extreme gut punch having them, and it put me on edge.

Touching a 401k for the purchase of a depreciating asset is a no go imo.

I had to take out a 401k loan about 5 years ago as a sort of bridge loan to buy out a business partner but it has paid itself back many times over.

Even then I would tread with caution as the risk of retirement $ loss linger overheard like a dark cloud.

Every case is unique but I would advise against buying a car with a 401k loan.

Wealth build mindset:
Money only goes into 401k. In only, frequency, over long period of time.

You are taking the whole amount out (lost opportunity up front and in full). You are essentially DCA filling the hole, but the hole is the thing you don’t want.

Speaking from threshold of retiring soon, that 401k is your wealth engine. Keep it happy! Trust me.

Don’t touch 401k for anything.

And go one further. Once you payoff the car loan, keep making the payment (but now to yourself). Pump it into the 401k or other investment account. If you can afford the payment, you can afford saving the payment.

Your future self will thank you.

Good luck.

If you have to pull out of your 401k to buy a vehicle, you can’t afford the vehicle.

Buy what you can afford or find alternate means of transportation.

What if it’s a ROTH 401k? Shouldn’t it go in after tax and be disbursed tax free?

Everyone is right. Avoid it if at possible. Yes it’s “your money” but you’re still paying it back. The car note should be around the same percentage rate. So you’re not saving on monthly payment.

Saying that, I’ve taken out multiple 401k loans but they were small amounts for short periods of time. Not sure I’d do large amounts for multiple years.

As others have said, the 401k is a retirement account it is not a savings account for buying things you want. You need to understand the tax implications of pulling money out. If you’re under 59 1/2, you will pay a 10% penalty in addition to your tax on the distribution. Also, you need to be clear on your repayment of the loan. Do you get company match on your contributions? Your deductions will go 100/% to loan repayment. This is a bad idea. Why not pay for the car out of your savings or finance it?
