Three tools, three structures
If you are carrying credit card debt, the goal is to pay less interest while you pay it off. A balance transfer card moves the balance to a card with a promotional rate for a limited window, usually for a transfer fee. A personal loan usually replaces the debt with fixed payments and a set end date. A line of credit lets you borrow and repay flexibly up to a limit, which is convenient but puts the discipline on you.
The best choice depends less on which tool sounds cheapest and more on whether you will follow through. A promo window that ends with the balance still there can cost more than a plain loan you paid on schedule.

How each tool is structured. Rates, fees, and terms come from the lender—check them live before you decide.
| Balance transfer card | Personal loan | Line of credit | |
|---|---|---|---|
| How it works | Debt moves to a card with a promo rate for a set window | A lump sum repaid in scheduled payments | Borrow and repay as you like, up to a limit |
| Payment structure | Minimum payments unless you set your own plan | Usually fixed payments with an end date | Flexible; minimums can be low |
| Costs to check | Transfer fee, promo length, rate after the promo | Interest rate, fees, prepayment terms | Interest rate, whether it is variable, fees |
| Best fit | A balance you can clear before the promo ends | People who want a forced, predictable payoff | Disciplined borrowers who want flexibility |
| Main risk | Balance left when the promo ends | Less flexibility if your budget changes | Debt can linger or grow without a plan |
| Credit card afterwards | Old card stays open—avoid new spending on it | Old card stays open—avoid new spending on it | Old card stays open—avoid new spending on it |

How to choose
- Can you clear it inside a promo window? Divide the balance plus the transfer fee by the months in the promo. If that monthly payment fits your budget, a balance transfer may fit.
- Need structure? If you know you will drift with a flexible payment, a fixed-payment loan forces the payoff.
- Need flexibility? A line of credit can work if you set your own fixed payment and stick to it. Most lines of credit are variable and priced off prime, which the big banks raised to 4.70% on October 29, 2026, so a line of credit costs more than it did a month ago. A fixed-rate loan, or a balance transfer promo rate for its promo period, won’t move if prime rises again.
- Stop the leak first Whatever you choose, the old card can fill back up. Pause new spending on it until the debt is cleared.
- Compare total cost Ask each lender for the full cost—fees plus interest—over the time you expect to need.
- Rewards wait While you carry a balance, interest usually beats any rewards. Optimize cash back or travel after the debt is gone.
Card Lab compares card types only. It does not compare personal loans or lines of credit, and it does not invent APRs, transfer fees, or loan rates. Ask your bank or lender for loan terms. Payoff Lab is a mortgage payoff calculator, not a credit-card debt tool.
After the debt is gone
Once you are paying in full every month, rewards start to make sense again. A no annual fee card keeps things simple, and the annual fee vs no annual fee guide shows how to tell when a fee card would pay for itself.
FAQ
Is a balance transfer better than a personal loan?
It depends on whether you can clear the balance before the promo ends. A balance transfer can cost less if you pay it off inside the window. A personal loan usually gives fixed payments and an end date, which suits people who want structure.
Can I use a line of credit to pay off a credit card?
Many people do. A line of credit offers flexible borrowing, so it works best if you set your own fixed payment and stop new spending on the card. Ask your lender about the rate, whether it is variable, and any fees.
What happens if I don’t pay off a balance transfer before the promo ends?
Whatever is left is charged at the card’s regular rate after the promo. Check that rate and plan payments that clear the balance plus the transfer fee inside the window.
Does Card Lab show loan or balance-transfer rates?
No. Card Lab does not invent APRs, transfer fees, or loan rates. Compare live balance-transfer offers on Ratehub and ask your bank or lender for loan terms.
