Discover it® 21 Month Balance Transfer Offer is Discover's take on a balance transfer credit card, and in many ways they have done a pretty good job. This card gives you everything you would expect from a Discover card, like high rates of cash back, no annual fee, and useful benefits. But this Discover it® 21 Month Balance Transfer Offer version is specially designed to help you escape high APRs by transferring your balance and enjoying a long, low intro APR period on balance transfers.

There are other credit cards that give you a longer introductory balance transfer period, and there are cards that give you similar cash back. But Discover it® 21 Month Balance Transfer Offer seems to magically combine the best of both worlds. In this Discover it® Card review, we'll show you the main benefits and disadvantages of this cash back/balance transfer credit card, and compare it with other similar credit cards.

Things We Like About Discover it® 21 Month Balance Transfer Offer

0% intro APR for 21 months on balance transfers and 0% intro APR for 6 months on purchases. Since this version of the card was created for balance transfers, we've listed this benefit first. 21 months is a pretty long period of time, and if your goal is to pay off your balance transfer, that should give you ample opportunity to do it. After the 0% intro APR for 21 months on balance transfers and 0% intro APR for 6 months on purchases you get a regular 11.49% - 23.49% variable APR. Sadly, a 3% fee applies to each transferred balance.

5% cash back in categories that change each quarter. This may be a balance transfer card, but it's cash back that makes this card shine. You earn 5% cash back in categories that change each quarter, up to the quarterly maximum. You will need to sign up for 5% cash back every quarter, but that's quick and easy to do (by phone or online).

1% cash back on all your other purchases. All the purchases you charge to this card will earn 1% cash back, so this is a rewarding card to use for your monthly spending.

Extra Cash Back With Discover Deals. As a cardmember you can access Discover Deals via the app or online. This portal lists all the latest coupons, cash back deals and discounts from Discover partner merchants. Most of the deals and discounts can be redeemed either online or at brick-and-mortar stores and restaurants, so you aren't confined to shopping online. Certain discounts are even applied automatically when you use your Discover it® 21 Month Balance Transfer Offer to pay at Discover Deals partners. If you want to earn high cash back on the stuff you would buy anyway, then Discover Deals is the way to go.

Discover's Cashback Match bonus offer! If you are a new cardmember Discover gives you a dollar-for-dollar match of all the cash back you've earned at the end of your first year, automatically. That means the cash back you earn during the first year is actually worth double. This bonus offer is a refreshing change from the typical credit card bonus offers which give you a set amount when you spend a minimum amount of money with you card. With this offer, you choose how much you spend and you get rewarded accordingly.

Redeem cash back in any amount, any time you want to. The cash back you earn in your Discover it® 21 Month Balance Transfer Offer account is recorded as Cashback Bonus. You can redeem the Cashback Bonus you collect for cash in several ways:

  • A direct deposit to your bank account (starting at 1 penny).
  • Partner gift cards (start from $20 Cashback Bonus).
  • A credit to your Discover Card account.
  • Pay with Cashback Bonus directly at select online retailers (no minimum).
  • Charity donation (options starting at 1 penny).

Most cards require that you collect a set amount of cash back rewards before you can actually redeem them for cash, but this card lets you choose when to redeem.

No annual fee. The cash back you earn with this card is actually a real bonus, because this card has no annual fee. You can use this card to earn cash back knowing that your rewards won't be negated by an annual fee.

Introductory low purchase APR period. You get a 0% intro APR on purchases for 6 months from the date of account opening. There are other cards that offer longer intro APR periods for purchases, but if you want to buy something right after getting this card and then pay off your balance before the 11.49% - 23.49% variable APR takes effect, you have the option.

FICO® Credit Scores. You can track your recent FICO® Credit Scores for free as a Discover it® 21 Month Balance Transfer Offer cardholder. Your FICO® Credit Scores appear in one easy-to-read chart on monthly statements & online. This is a big benefit, as you would normally have to pay a monthly fee to access your FICO® Credit Score. This score is one of the most widely used credit scores in the U.S. and it gives you a good idea of what your creditworthiness looks like.

Freeze It® on/off switch. This Discover perk can save you a lot of headaches by letting you freeze or unfreeze your credit card account in minutes right on your phone or online. If you misplace or lose your card, or if you think your card or credit card information may have been stolen, you can simply freeze your account until the situation is resolved. Freezing your account does not affect any recurring transfers or other important charges that you have agreed to, so your important bills will still be paid. But it does prevent anyone from using your account to make purchases or get cash advances. Most other credit card companies require that you submit a request to freeze your account by phone or mail, and then freeze your account for a set amount of time, normally a week. During that time you would have to go without your credit card, which isn't very practical. Discover's Freeze It® on/off switch makes keeping a tight thumb on your account a whole lot easier.

No foreign transaction fee. Most credit cards charge a fee equal to 3% of the amount you pay for any transaction in a foreign currency. But this card doesn't charge you a foreign transaction fee. So when you buy that must have curio or pay for your hotel while on vacation outside of the U.S., you won't pay an extra foreign transaction fee if you charge it to Discover it® 21 Month Balance Transfer Offer.

No late fee on your first late payment. If some disaster prevents you from making your credit card payment on time, you won't have to pay a late fee the first time you pay late. That's a nice perk, but the real benefit is that your APR won't be bumped up to a penalty APR when you pay late, like it would with most other credit cards. Still, you should avoid paying late like the plague, as it will affect your credit score. A good way to avoid late credit card payments is to set up a recurring transfer directly from your checking account to your credit card company.

All transactions are monitored by Discover. If a purchase or cash advance made with your card looks suspicious, you will be alerted by phone, text or mail. You can then confirm the transaction or take steps to prevent fraudulent use of your card.

You are never responsible for unauthorized purchases. If someone uses your credit card to make purchases without your authorization, for example if your card is stolen, you will not be held liable to pay for those purchases. That perk gives you a lot of peace of mind.

Redeem Cashback Bonus for purchases on When you shop on, you can use your Cashback Bonus to pay directly at checkout. That's a nice option if you use to buy stuff.

100% U.S. based customer services. If you are tired of fighting to be understood by customer service representatives that should be helping you, then the U.S. based customer service you get with this card 24/7 will be a breath of fresh air. Discover has received the highest ratings for customer service out of all major U.S. credit card companies.

Our Least Favorite Things About Discover it® 21 Month Balance Transfer Offer

Not very useful for international travelers. Discover it® 21 Month Balance Transfer Offer is an excellent cash back credit card and does a good job as a balance transfer card as well, but don't expect to find a lot of merchants that accept this card outside of the United States. However, Discover has been expanding its network and is now more widely accepted than it used to be. Besides merchants in the Discover Global Network and Pulse ATMs, you can also use your Discover card at these locations:

  • Merchants and ATMs that accept Diners Club International
  • Merchants and ATMs that accept China Union Pay (widely used in China)
  • Merchants that accept JCB (widely accepted in Japan)
  • Link ATMs (in the United Kingdom)

Discover it® 21 Month Balance Transfer Offer strikes a good balance as both a cash back credit card and a balance transfer credit card. If you don't need cash back and just want a balance transfer card, there are better cards for balance transfers.

Discover it® 21 Month Balance Transfer Offer will suit you best if you want to earn great cash back, and also happen to have a balance that you would like to transfer and pay off. Because you pay a balance transfer fee equal to 3% of each transferred balance, this may not be the best balance transfer card to use if you have a very large balance to transfer. In that case you may be better off getting a specialized balance transfer card just to consolidate your debts.

But coming across a card that gives you this kind of cash back (consider what you can save) and a long 0% intro APR for 21 months on balance transfers and 0% intro APR for 6 months on purchases followed by a reasonable 11.49% - 23.49% variable APR isn't something that's so common and is a niche which Discover it® 21 Month Balance Transfer Offer fills nicely.
