Quick answer
A balance transfer is strongest when the debt fits and clears inside the promo. A personal loan is strongest when a fixed payoff date prevents promo rollover risk.
If balance transfer
Best when the fee is modest, the limit covers the debt and your payment clears it before expiration.
If personal loan
Best when the all-in APR is competitive and a fixed schedule improves execution.
If current card
Reasonable only when the current APR or negotiated terms beat the new all-in offers.
Key number to watch
About $686.67 per month is required to clear the transferred balance plus fee within 18 months.
