In one way, it seems like a no-brainer:
Interest on 401K loan = I guesstimate about 10% (more on that below) - Paid to MYSELF...
Interest on Credit Card = about 20%
Loan would be used to either pay off my credit card or my car. I owe just shy of $5k on my card, and a little less than that on my car. BTW, I plan on keeping that car for as LONG as I can!!!
Now, er, I've already taken out two smaller loan on it - one is paid off in a few weeks, the other should be paid off in about 2 years...
This is why I don't know for SURE what the interest rate would be.
I know, I KNOW...I promise I'll be good this time if I can get (relatively) debt-free!
But now - assuming I DO NOT take the loan:
The car will be paid off next September.
The card, SHOULD be paid off by this time next year at the VERY LATEST. Well, barring any 'troubles.'
That's pretty close...but still, I wonder if it'd be worth it to save on interest charges...?
