Why We Like It

Why We Like the Citi® Diamond Preferred® Card

If you need a little more time to make a dent in your debt, the Citi® Diamond Preferred® Card, from our partner Citi, offers you the chance to make it happen. The extended 21 months of 0% intro APR is the biggest reason this credit card is among the best for balance transfers to wipe out existing credit card debt.

On top of that, you also get a 0% intro APR on purchases for 12 months. While this card has no annual fee, it does have a balance transfer fee of $5 or 5% of the amount of the transfer, whichever is greater. However, interest savings are likely to offset any balance transfer fee.

Balance Transfers: 0% Intro APR

The extended 21 months of 0% intro APR is the biggest reason this credit card is among the best for balance transfers to wipe out existing credit card debt. While it seems we keep saying it again and again in this review, the 21-month introductory 0% APR period puts the Citi Diamond Preferred Card near the top.

To get a better idea of what you could save, here’s an example. Let’s say you have $10,000 in credit card balances from cards that charge an average of 25% APR. Paying $250 per month toward that debt, you would wind up needing more than seven years to pay off the cards. Moreover, you will end up paying $11,725 in interest. That’s a huge expense and a ton of money.

If you transfer that $10,000 balance to Citi Diamond Preferred Card (along with the 5% balance transfer fee) and could pay $500 per month, that debt would be wiped out completely in 21 months without paying any interest. But even paying the same $250 per month in the previous example, you could still pay off nearly half of the debt without incurring any interest.

In this example, even with a $500 fee for balance transfers, you would save over $10,000 by taking advantage of this 0% APR offer. That’s life-changing money for many households.

New Purchases: 0% Intro APR

If you are the kind of person who doesn’t typically carry credit card debt from month to month, you’re a savvy credit card user. Paying off your balance in full every month means you never have to pay interest.

But if you want to borrow in the short-term for up to a 12 months, Citi Diamond Preferred Card could make it okay to carry a balance on your credit card. The trick is paying the balance off before the 0% period ends so you don’t get stuck paying interest on the 13th month.

Additionally, as a limited time offer, earn a $150 Statement Credit after you spend $500 on purchases in the first 3 months of account opening.

How to Maximize Intro APRs

With intro APRs for both purchases and balance transfers, you have opportunities to save many thousands of dollars in interest charges. The trick to getting the best deal comes to using the full introductory periods without going over.

If you have credit cards or other loans that currently charge interest rates above what the Citi Diamond Preferred Card charges, it’s almost certainly a better idea to go forward with a balance transfer. If your other cards have a lower interest rate after the 0% APR period, seriously look at your prospects for paying off the full debt amount within 21 months.

For purchases, avoid buying anything you can’t pay off in full before the end of the 12-month intro period. Making a major purchase interest-free can be very helpful for your monthly cash flow. However, if it turns into a bigger expense after a year, it may not be as good of a deal for your finances.


Most Citi cards don’t have extensive purchase or travel benefits. However, this card does include some useful added features that could come in handy to some cardholders.

Free FICO ScoreWith this card, and others from Citi, you can view your real FICO score that Citi uses to assess your credit risk.
Citi EntertainmentGet access to exclusive ticket presales and events including dining experiences, sporting events, concerts and more.

If you’re looking to transfer high-interest debt and don’t want to pay an annual fee, the Citi Diamond Preferred Card may be the right solution for you.

0% Introductory PeriodsThe 21-month introductory period for balance transfers and 12-month introductory period for purchases are the top benefits of this card.
No Annual FeeUse and keep the card with no annual fee. If you avoid certain fee-bearing activity, you can use the card without paying any interest or fees.
