You can also call the company or companies you have the cards with and ask for a lower interest rate

I agree. People don’t take the time to understand the rules then get pissed when they do something not knowing what the consequences will be

You raise good points, but really I think it depends on the terms of the 401k loan. You’d have to read the plan document to see what it says about the interest. I was more so saying don’t do a 401k loan because of potential penalties if you don’t repay it back in a certain amount of time, mandatory holding periods must be reached or there’s required 20% withholding, etc.

I was thinking of other factors too like building / rebuilding credit, how much of an account balance is in there vs how much is in credit card debt

I think a 401k loan is a bad idea for the majority of people. I would recommend getting a loan from a bank instead. If you can get a loan from the bank you’re going to save a ton compared to the interest you’d pay otherwise
