Lowering your rate can be as simple as asking the issuer to give you a better deal; but you may save more by snapping up a 0% rate (usually for an introductory period of up to 21 months) for a balance transfer. You’ll likely pay a transfer fee of 3% to 4%. If you can’t pay off the debt during the introductory period, see whether shifting to a card with no transfer fee and a lower rate will benefit you more.

Another option for credit card debt or a car loan: a home-equity loan (recent average, 6.9%) or line of credit (5.2%). Americans overindulged in home-equity borrowing during the housing bubble, and lenders are wary of extending too much credit. Still, they’re making loans again to homeowners with plenty of equity, and interest on home-equity debt is tax-deductible up to certain limits. Or, if you are planning to refinance your mortgage, consider a cash-out refi, says Adrian Nazari, chief executive of CreditSesame.com, and use the extra funds to pay off debt. Average rates on 30-year fixed mortgages are about 4%, and the interest is tax-deductible.
