What credit score do I need?

You typically have better odds of getting a balance transfer credit card with a good to excellent credit score of 670 or higher. This is a good rule of thumb if you’re thinking about applying for the Citi® Diamond Preferred® Card. However, remember that approval is never guaranteed no matter what your credit score is.

Citi® Diamond Preferred® Card benefits

The Citi® Diamond Preferred® Card doesn’t offer many benefits, but it’s an excellent card for intro APRs. Here are the main perks to look into.

  • No annual fee. Having a $0 annual fee makes it easy to keep your Citi® Diamond Preferred® Card open even after your intro APR expires. Even if you won’t earn rewards, keeping your card open keeps your average age of credit accounts high and protect your FICO score.
  • Excellent balance transfer APR. Get a 0% intro APR on balance transfers for 18 months from the date of your first transfer, then 14.74% to 24.74% variable. You’ll get this rate on all transfers within the first 4 months of card membership.
    Its intro APR is what makes the Citi® Diamond Preferred® Card stand out among competitors. You’ll often find intro APRs that last around 15 months — 18 months is considered very high.
  • Long purchase intro APR. Get a 0% intro APR on purchases for 18 months after account opening, then 14.74% to 24.74% variable. This is a longer intro APR on purchases than you’ll typically find with competing products — most 1.5% cashback credit cards have purchase intro APRs of 15 months.
    You can leverage the Citi® Diamond Preferred® Card’s interest-rate promotion to make purchases you’d like to pay off over a long period of time. But be sure to clear your purchase balance before the intro APR expires, or you’ll start accruing interest. For an idea of how much money you can save with a transfer, check out our balance transfer calculator.
  • Four-month limit to transfer your balance. After you open your account, you’ll have four months to make transfers to qualify for the promotional interest rate. This is a higher length of time than the average balance transfer credit card. Most give you just 30 to 60 days to make your balance transfer, so the Citi® Diamond Preferred® Card effectively gives you double that length.

Citi® Diamond Preferred® Card drawbacks

Before applying for this card, determine if the benefits outweigh the drawbacks. Here are a few factors to keep your eyes peeled for.

  • You’ll still pay balance transfer fees. Even though you get a top-notch balance transfer intro APR, you’ll still pay fees on your transfers: the greater of $5 or 3% for each transaction.
  • No rewards or welcome offer. This card is strictly designed for saving interest on balance transfers and purchases during the intro offer period. Aside from any interest saved during this time, you won’t have any additional method of generating value such as points or cash back with this card.
  • There’s a steep penalty APR. If you make a late or returned payment, Citi may increase the APRs on all of your balances to up to 29.99% variable. Consumers despise this, and rightfully so. It creates a lot of pressure to be perfect every single billing cycle. Citi also says you can lose your intro APR if you make one late payment, which makes it extra important to stay vigilant about paying your card bill.

I got my Citi Diamond Preferred card solely as a balance transfer card to help me consolidate and pay down debt I’d accumulated renovating my home. As with other cards, it took me about 15 minutes to fill out the form, approval was close to instant, and my balances were transferred within a few days.

The thing that has kept this card as a go-to in my wallet is that Citi regularly sends me low or 0% APR offers generally reserved for new cardholders. Though I’m trying really hard to stop spending money I don’t have, it’s nice to know these offers are available should I need them. It saves me the trouble of applying for a new card.

Citi® Diamond Preferred® Card customer reviews and complaints

Citibank is not accredited with the Better Business Bureau and sports a rating of F as of April 2021. Customer reviews on the BBB site give the bank a 1.04 out of 5, citing poor communication and billing issues as a frequent complaint.

Citibank doesn’t fare much better on Trustpilot, earning a 1.5 out of 5 based on customer reviews as of April 2021, with poor customer service a frequent complaint.

Bottom line

The Citi® Diamond Preferred® Card is a great choice if you want to save interest on your existing debt as well as purchases within your first 18 months. If saving is your main concern, you won’t mind that the card lacks other benefits, such as rewards.

Of course, the Citi® Diamond Preferred® Card isn’t the only card in town. There are plenty of other balance transfer cards that are worth a look, too, including Citi’s own Citi Double Cash, which offers a smaller balance transfer offer and no purchase intro APR, but unlimited 2% cash back on purchases.
