Why you might want the Discover it® Cash Back

The robust rewards and benefits on the Discover it® Cash Back make it one of the most valuable everyday cash-back cards available.

5% cash back in rotating categories

You would be hard-pressed to find a card with no annual fee that earns more than 5% cash back in bonus categories, which for the Discover it® Cash Back have recently included things like gas stations, grocery stores, restaurants, and more.

If you max out the 5% rotating quarterly category rewards each year on this card — that is, if you activated and spent up to $1,500 in those categories each quarter all year — you would earn $300 in bonus cash back, plus 1% back on every other purchase. For many shoppers, those lucrative ongoing rewards make this card a keeper.

A potentially valuable sign-up offer

The Discover it® Cash Back comes with an uncommon sign-up bonus for new cardmembers in their first year: INTRO OFFER: Unlimited Cashback Match – only from Discover. Discover will automatically match all the cash back you’ve earned at the end of your first year! There’s no minimum spending or maximum rewards. You could turn $150 cash back into $300.

For example, if you earned $500 in rewards, Discover will give you another $500 in cash back at the end of your first consecutive 12 months of being a cardholder. For folks who plan to do a lot of spending on the card during that time, this unusual offer could prove incredibly valuable.

Introductory 0% APR period

The Discover it® Cash Back offers plenty of breathing room for paying off balances after opening the account. It comes with a generous introductory offer: 0% intro APR for 14 months on purchases and balance transfers, and then the ongoing APR of 11.99%-22.99% Variable APR. The balance transfer fee is an introductory 3% of the amount transferred, but can be as high as 5% on future balance transfers (see terms). That's on par with other balance transfer cards.

If you want to make a large purchase and pay it off over time, this is an especially valuable perk. Just keep in mind that if you're using the card as a balance transfer option, you'll likely want to avoid making new purchases with it, and instead use the card solely for paying off debt. That might mean missing out on the rich sign-up bonus offer.

Discover it® Cash Back vs. Chase Freedom Flex℠

Looking at cards that offer 5% cash-back rewards on rotating quarterly categories? Chances are the Chase Freedom Flex℠ has been on your radar, too. At first glance, this card seems like a mirror image of the Discover it® Cash Back. But if you look a bit closer, a few important differences stand out.

What these cards have in common:

  • 5% cash back in rotating quarterly bonus categories on the first $1,500 in purchases each quarter. All other purchases earn 1% back.

  • A variety of bonus categories. Historically, they’ve ranged from broad options like restaurants and gas stations to specific retailers like Walgreens or Past bonus categories can help you see what types of categories to expect in the future.

  • Requirement to activate quarterly categories.

  • No annual fee.

What's different about the Chase Freedom Flex℠:

  • Sign-up bonus can be earned quickly. You don't have to wait a full year to collect your bonus. A lot of people can claim it with less than a month's worth of spending.

  • Fixed bonuses in certain categories: Not only will you get rotating bonus categories, but you'll also earn heightened rewards anytime on certain purchases. Get 5% cash back on travel booked through Chase Ultimate Rewards®, 3% cash back on dining and drugstores and 1% cash back on all other purchases.

  • Slightly longer introductory 0% APR offer.

  • Rewards can be earned retroactively if you activate the categories by the 14th of the third month of the quarter; this is not the case with the Discover it® Cash Back.

  • Bonus categories aren't announced all at once: Unlike eligible Discover cards, the Chase Freedom Flex℠ doesn't reveal its full slate of quarterly bonus categories for the entire year. Category announcements come only a couple of weeks before the start of a new quarter, which can make it harder to plan purchases.

  • It charges foreign transaction fees.

Why you might want a different card

The Discover it® Cash Back isn’t the best fit for everyone. Here’s why you might want to look elsewhere.

Other cards offer simplicity

With rotating bonus categories that require quarterly activation, the Discover it® Cash Back is a relatively complicated card. If you want something more straightforward, try the Citi® Double Cash Card – 18 month BT offer.

This card offers an impressive 2% cash back on everything — 1% back on purchases and 1% back when you pay them off. With it, you can rake in big rewards for everyday spending without having to mess with bonus categories. Its annual fee is $0.

Choose a bonus category

With the Discover it® Cash Back, you don't have a say in which categories earn 5% cash back. With the Bank of America® Customized Cash Rewards credit card, it's a different story. You earn 3% cash back in a category of your choice (from among six options); 2% cash back at grocery stores and wholesale clubs (on up to $2,500 per quarter in combine spending in the 3% and 2% categories, then 1%); and 1% cash back on everything else. For the 3% category, you can choose from gas, online shopping, dining, travel, drugstores or home improvement/furnishings, and you can change the category each month.
