Balance-transfer card vs. personal loan: which payoff path costs less?

Quick answer

A balance transfer can cost less when it covers the debt and you can pay it off before the special rate ends. A personal loan can be safer when you need a fixed payment and payoff date.

If balance transfer

Usually better when the fee is low, the limit covers the debt, and you can finish payments before the special rate ends.

If personal loan

Usually better when the total APR and fees are competitive and a fixed payment keeps you on track.

If current card

Can make sense only when your current card company lowers the rate or new offers cost more after fees.

Key number to watch

About $686.67 per month is required to clear the transferred balance plus fee within 18 months.

Card paths use monthly declining balances, the transfer fee and post-promo APR; the loan uses fixed amortization plus entered fee.

All rates and approvals are editable scenarios, not market promises.

  • Minimum-payment formulas and allocation rules vary.
  • Credit effects and approval odds are not predicted.
  • Late fees and penalty APRs are not quantified.
