Citi Diamond Preferred Review: A Debt-Crushing Tool with 21 Months of 0% APR

Review Updated
Joel O'Leary
Nathan Alderman
Many or all of the products here are from our partners that compensate us. It’s how we make money. But our editorial integrity ensures that our product ratings are not influenced by compensation. Citi is an advertising partner of Motley Fool Money.

A few years ago, a buddy of mine found himself buried under $30,000 in credit card debt. He was stuck paying just the minimum every month and getting crushed by interest charges.

Then I helped him get approved for a 0% intro APR card. And once that interest was paused, he went HAM on his debt. In just 18 months, he wiped out his entire balance and saved around $8,700 in interest.

That's why I'm such a big believer in 0% intro APR cards. And today I'm going to review one of the best available: The Citi® Diamond Preferred® Card. Keep reading to see why it might be the perfect fit for your financial goals.

What I like about the Citi Diamond Preferred

If you're like my friend was and buried in debt, relief might be right around the corner. This card is built mainly for balance transfers, and that's hands down its biggest benefit.

Huge 0% balance transfer window

The Citi Diamond Preferred offers one of the longest 0% APR periods for balance transfers available today.

Here are the intro offer details: 0% intro APR for 21 months on Balance Transfers from date of account opening. After that, the standard 17.24% - 27.99% (Variable) APR will apply, based on your creditworthiness.

That's nearly two years of no interest. This gives you a big window of opportunity to make some real progress on even the ugliest debt.

0% for new purchases

Instead of transferring an existing balance, you could instead get some breathing room on new purchases.

This card offers 0% intro APR for 12 months on Purchases. After that, the standard 17.24% - 27.99% (Variable) APR will apply, based on your creditworthiness.

This full year of interest-free spending can really come in handy for big expenses.

$0 annual fee

Some balance transfer cards sneak in hidden costs. Not this one. The Citi Diamond Preferred card has a $0 annual fee, making it a clean, no-gimmicks tool for consolidating and paying off debt.

Downsides you should consider

In my eyes, these downsides are not dealbreakers. But I still want to call them out to make sure you're picking the right card for your situation.

No rewards program or sign-up bonus

If you're hoping to rack up points, miles, or cash back, this card won't scratch that itch.

Remember the main goal of this card is to deliver a long 0% intro period -- not dish out rewards or a hefty sign-up bonus.

High balance transfer fee

Balance transfer fee applies with this offer; 5% of each balance transfer; $5 minimum.

The transfer fee is on the high side and could sting for larger balances. For example, transferring $10,000 would cost $500 up front.

That being said, if it means saving $2,000 in interest, it's still worth it.

If you're looking for a slightly lesser fee, check out the Citi Simplicity® Card, which offers a lower intro balance transfer fee for a number of months from account opening.

Is the Citi Diamond Preferred worth it?

If you can save more in interest than the cost of transfer fees, yes, absolutely this card is worth it. In my friend's situation, he saved $8,700 and got out of debt in about 18 months.

If you're considering a balance transfer, I encourage you to use our balance transfer calculator to see what type of money you can save.

Another scenario where this card pays off big time is financing a large new purchase. Paying no interest (as long as you pay off the entire balance within the 0% intro APR window) is a huge win over accumulating expensive debt.

What this could look like in real dollars

Let's say you're carrying a $15,000 credit card balance on a card charging 27% APR. That's nearly $340/month in interest alone.

You decide to transfer the full balance to the Citi® Diamond Preferred® Card. You'll owe a $750 balance transfer fee. After that, you get a 0% intro APR for 21 months on Balance Transfers, meaning every dollar you pay goes directly toward your balance, not interest.

If you divide your payoff plan over the full balance transfer window, that's about $750/month (plus the upfront $750 fee). Total interest saved? Roughly $4,077 compared to just letting that debt sit on your old card.

Pretty powerful, hey!?

How to apply for the Citi Diamond Preferred

Submitting an application is super quick. And most people get an answer within minutes. Here are the steps you need to take:

1. First, check your credit

You'll want a credit score or 670 or higher to have the best shot for this card.

If you're under that currently, consider the Citi Double Cash® Card which can be easier to qualify for, and still has a great 0% intro APR period.

2. Fill out an online form

Here is the direct link to apply.

You'll be asked for your personal info, including:

  • Name and address
  • SSN
  • Income and job info
  • Housing payment

Just make sure to double-check all the information you submit, because errors can cause delays in getting approved. And remember to be honest and truthful -- but that goes without saying.

3. Submit and wait

Most approvals happen instantly. If not, Citi will mail you with their decision reasoning and any next steps to apply. Sometimes they will request verification of the info you submitted.

Once approved, your card usually ships within seven to 10 business days.

4. Transfer your balance and crush your debt

Don't forget to move your balance fast and start hammering it down. Take advantage while the 0% intro APR window is wide open.

Every payment now = pure progress with zero interest holding you back. Speed is your best friend with 0% intro balance transfers.

Final thoughts

The Citi® Diamond Preferred® Card can be an awesome tool to help you get out of debt quicker. Or, it can give you a large window of interest-free payments on new purchases.

But, you really need to be serious about paying off your FULL balances during the 0% APR window for this strategy to make sense. You don't want to end up in a worse situation later.
