The Danger: Running Up Cards Again
The biggest risk isn’t the math — it’s behavior. If you pay off your cards with a 401k loan but then run up the cards again, you’ll have:
- 401k loan payments: $421/month
- New credit card debt: growing at 24.5%
- Double the debt: worse than where you started
When It Makes Sense
- You have a written budget that prevents new credit card debt
- You’re committed to cutting up or freezing your cards
- You have stable employment for the 5-year term
- The savings ($18,000+ in this example) justify the retirement risk
- You’ve addressed the root cause of the debt
Safer Alternatives
- 0% balance transfer card — 12-18 months interest-free
- Debt consolidation personal loan — lower fixed rate
- Debt management plan — through a credit counseling agency
- Snowball/avalanche method — systematic payoff without new borrowing
- Negotiate with card issuers — some will lower your rate if you ask
