Not sure which card saves you the most?

Take a quick quiz and we'll find out.

Get started
If you have credit card debt or plan to make a big purchase, a low-interest credit card can be a lifesaver. Many offer more than a year of 0% APR to pay down your debts, or a low ongoing interest rate for a longer-term debt reduction strategy. These cards are the best in the business, from waived fees to rewards and more. Transfer your balance, and you’ll get some room to breathe — and a chance to get out of debt.
Our pick for

Longest 0% intro APR period




Benefits

The interest-free period on the Citi Simplicity® Card - No Late Fees Ever is among the longest we’ve seen: 0% on Purchases and Balance Transfers for 21 months, and then the ongoing APR of 14.99% - 24.99% Variable APR. Citi’s pledge to never charge fees or a penalty annual percentage rate on late payments is unusual and a nice break for the chronically forgetful.

The lengthy interest-free period comes at a cost for balance transfers: 3%, which adds up for big balances. The no-late-fee policy could encourage bad behavior that might eventually affect your credit scores. No rewards or sign-up bonus.
This card’s long 0% APR period means you’ll have more time to offset the balance-transfer fee in interest savings. Its lack of penalties for late payments can help by not adding to your debt.
Our pick for

Sign-up bonus


Benefits

The Chase Freedom® gives you a little of everything. In addition to a $0 annual fee and a long 0% APR period on purchases and balance transfers, it offers a nifty sign-up bonus. You get 5% cash back on up to $1,500 per quarter in spending on rotating bonus categories that include such things as gas stations, supermarkets and restaurants. All other spending earns 1% back.

The 5% balance-transfer fee is high and could be a burden if you’re trying to get out of debt. A $3,000 balance transfer would consume the sign-up bonus. And it can be a hassle to track bonus rewards categories and opt in to them every quarter.
Free money from a sign-up bonus is always nice, and the lengthy 0% APR period makes the Chase Freedom® a solid choice for financing a major purchase. It’s a poor option for balance transfers, though, because of its high fee.
Our pick for

Rewards


Benefits

Offering 1% cash back on every purchase and an additional 1% when you pay them off, the Citi® Double Cash Card – 18 month BT offer provides easy rewards to go with its lengthy interest-free period on balance transfers and $0 annual fee. This is an excellent card that doesn’t require excellent credit: You can qualify with good credit.

Although the card offers a long 0% APR period to encourage balance transfers, it also comes with a 3% fee on transfers. There’s no sign-up bonus, and there’s a $25 minimum rewards redemption. Some cards have no minimum.
If you like to keep it simple while paying down transferred debt, the Citi® Double Cash Card – 18 month BT offer gives you generous rewards and a lengthy no-interest period. Unlike some transfer cards, this one is a keeper long after the 0% period ends.
Our pick for

Low fees


Benefits

This card combines a lengthy 0% period on balance transfers with 5% cash-back rewards on rotating bonus categories (on up to $1,500 in spending per quarter) and 1% back on all other spending. There’s also an unusual bonus, which Discover describes as: “Discover will match ALL the cash back earned at the end of your first year, automatically.” No foreign transaction fee is unusual for this category. Discover won’t charge a fee for your first late payment or raise your APR for paying late.

The 3% balance-transfer fee will eat into interest savings during the introductory period, and the no-interest offer on new purchases is shorter than for other top cards. It can be a hassle to track bonus rewards categories and opt in to them every quarter.
The Discover it® - 18 Month Balance Transfer Offer has generous rewards and a lengthy interest-free period for balance transfers, although not as much for new purchases. However, the card allows you to earn rewards while creating breathing room to get out of debt.
