Citi Simplicity vs. Citi Diamond Preferred highlights

The Citi Simplicity and Citi Diamond Preferred cards are primarily balance transfer credit cards, so the highlights are not rewards or welcome offers. Not much differentiates these two cards except their ongoing variable APRs, recommended credit score for qualification and attached card benefits.

To start, here’s a look at how the two cards compare when it comes to intro APRs, fees and more.

Intro APR winner: Tie

Considering both cards offer identical intro zero-interest purchase and balance transfer offers, they tie in this category. Note that for both cards, balance transfers must be made in the first four months of card ownership or else you will pay the regular variable APR on your transferred balance.

The Diamond Preferred card does offer a slightly lower variable APR compared to the Citi Simplicity, which could make a difference if you anticipate taking longer than the intro periods to pay off your balance.

Balance transfer fee winner: Citi Simplicity

The Citi Simplicity offers a lower introductory balance transfer fee: 3 percent ($5 minimum) for the first four months. After four months, the fee rises to 5 percent ($5 minimum), matching that of the Citi Diamond Preferred.

As long as you transfer your balance within that time period, the Citi Simplicity comes out on top in this category. Remember, too, that you have to transfer within that first four-month time period if you want to take advantage of the intro APR offer.

Welcome bonus and rewards rate winner: Tie

The Citi Simplicity and Citi Diamond Preferred do not offer welcome bonuses or ongoing rewards. The main appeal of these cards is their industry-leading, zero-interest balance transfers offers.

Every once in a while, Citi does roll out a limited time bonus on one of these cards, but it’s certainly the exception rather than the rule. If you need a balance transfer to save on interest, don’t wait to apply hoping for a welcome offer.

Annual fee winner: Tie

Neither Citi Simplicity nor Diamond Preferred charge an annual fee. This is a key perk for cardholders looking to manage debt with a balance transfer card without worrying about an added yearly fee.

Foreign transaction fee winner: Tie

Neither is a good choice for traveling abroad or making purchases in foreign currency. They both charge a 3 percent foreign transaction fee. If you plan to travel or study abroad and want to use a credit card, we recommend choosing from among the best cards with no foreign transaction fees.

Which card is best for balance transfers?

Citi Simplicity vs. Citi Diamond Preferred balance transfer example

Both cards offer the same lengthy intro 21-month balance transfer APR offer (19.24 percent to 29.99 percent variable APR after for Simplicity and 18.24 percent to 28.99 percent variable APR after for Diamond Preferred). Here’s how much you’ll pay for a $4,000 balance transfer to either of these cards when you complete your transfer in the first four months and factor in their balance transfer fees:

  • Citi Simplicity — you’ll pay $4,120 over 21 months, or just over $196 per month ($4,000 + 3% balance transfer fee of $120 = $4,120)
  • Citi Diamond Preferred — you’ll pay $4,200 over 21 months, or $200 per month ($4,000 + 3% balance transfer fee of $120 = $4,200)

Now, let’s say life gets in the way, and you miss a payment.

If you have the Citi Simplicity, you won’t pay any late payment fees or be hit with a penalty APR. You will have to increase your monthly payments if you still want to pay off the balance by the end of the 0 percent APR period.

With the Citi Diamond Preferred, however, Citi may apply up to a $41 late fee. But more importantly, Citi may also decide to end your introductory period and apply a penalty APR of up to 29.99 percent instead. Let’s say you missed a payment after three months, meaning your balance at that time is $3,600. Using Bankrate’s credit card payoff calculator, and assuming a penalty APR of 29.99 percent, it’ll take you 25 months to clear your balance — which will also accrue $1,242 in interest, if you continue making $200 monthly payments.

Why should you get the Citi Simplicity?

Additional benefits

The main benefits of the Citi Simplicity is its lack of late fees and a penalty APR should you miss a payment. That’s a significant divergence from most balance transfer credit cards that often forfeit your intro APR if you miss a payment. Furthermore, Simplicity cardholders have access to Citi Identity Theft Solutions, zero-liability protection and account activity alerts.

Recommended credit score

Citi doesn’t publish recommended credit scores to qualify for any of its credit card products. However, the balance transfer offer period and lower-than-average minimum ongoing variable APR leads us to recommend applying with at least a good credit score (670 and up).

Why should you get Citi Diamond Preferred?

Additional benefits

Citi Diamond Preferred cardholders have access to Citi Entertainment, the issuer’s experience portal that offers exclusive access to VIP tickets, dining, concerts, sporting events and more. It also comes with zero-liability protection and free FICO score access.

Recommended credit score

Similar to the Citi Simplicity, we recommend that you have a good credit score (670 and up) before applying.

The bottom line

The Citi Simplicity and Citi Diamond Preferred are similar, but their differences may be enough to push one card in your favor.

If you want access to shopping deals and social experiences with your balance transfer card, then Diamond Preferred is the card for you. If it’s more important to you to avoid penalty APRs and late fees no matter what, go with the Simplicity.
