Personal Loan vs Credit Card vs Line of Credit
Which borrowing option is cheapest for your situation — and if you have a personal loan, does early payoff make sense?
Quick Answer
- vs. Credit card: Personal loan wins for amounts over $2,000 that take more than 2–3 months to repay
- vs. Line of credit: Personal loan wins for fixed expenses; LOC wins for ongoing/variable needs
- Cheapest borrow: 0% promo card → HELOC → credit union loan → online loan → bank loan → credit card
- Early payoff: Yes — most personal loans allow it with no penalty and full interest savings

Frequently Asked Questions
For large purchases you can't repay within 1–2 billing cycles, a personal loan is almost always cheaper — fixed rates of 8–18% vs. credit card rates of 20–29%. Use a credit card only if you'll pay it off within the intro period (0% APR offers) or within the month. For recurring expenses you can't predict in advance, a credit card offers more flexibility.
