Help with 401K loan math? Compared to HML?
Hello, I would like some help understanding the math related to taking a 401K loan.
- I have a 401K which allows up to $50,000 loan for any purpose
- 6.5% interest
- time period can be 6 to 60 months
- it is paid back with bi-weekly payments taken from my paycheck (after taxes)
So originally, I thought 'oh great, a loan at 6.5% sounds good'. Now I'm realizing that even though I'm paying myself back, I'm using after-tax dollars to do it.
What's the real interest rate if you consider the after-tax component?
Wondering if a HML is actually better option if judging by the numbers only?
Any help is appreciated?

Two additional things you have to take into account:
How will that $50,000 would perform if you didn't take it from your 401k. This will depend on the type of investments you have it in currently. If it's in equities or mutual funds and the market goes up, then it hurts the case for taking a loan even more. If the market goes down or has a very timely pullback, then you may look like a genius. If you are in money market or low-yield bonds then this consideration may not be as relevant. The takeaway here is that it could be a very unpredictable variable.
Secondly, when you do take out a loan against your 401k, does your employer allow you to continue to make contributions (in addition to what you are paying back every paycheck), and if so, will they continue to match said contributions. Many larger employers don't and this would be a significant strike against using your 401k.
