Carrying $5,000 in credit card debt at a 22 percent APR will cost you about $1,100 a year in interest if you only make minimum payments. The Citi Diamond Preferred is built for one specific job: stopping that interest cold so you can actually pay off the balance.
It is not a rewards card. There is no welcome bonus, no cash back, and no points. What it does have is one of the longest 0 percent intro APR offers in the market. That is the entire point of the card, and this review walks through whether it makes sense for you.
Citi Diamond Preferred at a glance
- Annual fee: $0
- Intro APR on balance transfers: 0 percent for 21 months from the date of first transfer (transfers must be completed within 4 months of account opening)
- Intro APR on purchases: 0 percent for 12 months from account opening
- Regular APR: variable, currently in the high-teens to high-20s range depending on creditworthiness
- Balance transfer fee: 5 percent of each transfer, with a $5 minimum
- Foreign transaction fee: 3 percent
- Rewards: none
Terms and conditions apply. Confirm current APR, intro periods, and fees on Citi's official site before applying.
How the balance transfer math works
Assume you move $5,000 of high-interest debt to the Diamond Preferred:
- Upfront cost: $250 (5 percent transfer fee)
- Interest during 21 months: $0
- Monthly payment to clear the balance in 21 months: about $250
Compare that to leaving the balance on a 22 percent APR card and paying $250 a month. You would still owe roughly $1,800 at the 21-month mark because so much of each payment went to interest. The Diamond Preferred saves about $1,500 in this scenario, even after the transfer fee.
The 21-month window is one of the longest in the market right now. A few competing cards offer similar lengths, but the Diamond Preferred is consistently at or near the top.
What this card does well
- The 21-month intro period gives you nearly two years to chip away at debt with every payment going to principal.
- No annual fee keeps the cost predictable.
- Citi Entertainment offers presale and exclusive access to concerts and sporting events. A small extra, but it is there.
- Free FICO score access and standard fraud protections.
What it does not do
This is the trade-off section. The Diamond Preferred has no:
- Rewards program (no cash back, no ThankYou Points)
- Welcome bonus
- Travel insurance worth highlighting
- Foreign transaction fee waiver
It is intentionally minimal. The card is engineered to do one job well rather than be a long-term daily driver.
Before you apply: protect your credit score
Applying for a new card triggers a hard inquiry, which can shave a few points off your score temporarily. If your credit is already thin or rebuilding, that hit matters more.
The Self Visa® Credit Card is one way to build a stronger profile before applying for balance-transfer cards. It is a secured card with no hard credit pull at application, and Self reports to all three major bureaus. Many users see their scores rise into the good range within 6 to 12 months of on-time payments, which improves their odds of approval and the intro APR length they qualify for.
How to use the Diamond Preferred without backfiring
A balance transfer can be a powerful tool, but it can also dig the hole deeper if you misuse it. A few rules to live by:
- Initiate the transfer within 4 months of account opening. Miss that window and you lose the intro APR on transferred balances.
- Stop charging on the old card. Otherwise you risk re-accumulating debt while paying off the transferred balance.
- Make every payment on time. A single late payment can void the intro APR.
- Pay more than the minimum. The 21 months only saves you money if you actually clear the balance. Divide your transferred amount (plus the 5 percent fee) by 21 to find the monthly payment that gets you to zero.
- Avoid new purchases. The intro APR for purchases is only 12 months, and any new spending complicates payoff math.
Who should consider the Diamond Preferred
This card fits you if:
- You are carrying $2,000 or more in high-APR credit card debt
- You have good to excellent credit, generally a FICO score of 690 or higher
- You can commit to a payoff plan and stop charging on the original card
- You do not need rewards or premium perks from this account
It is the wrong card if you want everyday rewards, travel benefits, or international fee-free spending. Pair it with a separate rewards card for daily use after the balance is gone.
Diamond Preferred vs Citi Simplicity
Citi also offers the Citi Simplicity Card, which targets the same balance-transfer audience. Key differences:
- Both have 0 percent intro APR offers on balance transfers, with similar lengths (check current terms on Citi's site)
- Simplicity is marketed around no late fees and no penalty APR
- Neither offers rewards
- Balance transfer fees are similar at around 5 percent
If you are nervous about ever missing a payment, the Simplicity's no late fee policy is a meaningful safety net. If your priority is the longest intro APR period possible, the Diamond Preferred typically wins.
Diamond Preferred vs Chase Slate Edge
Chase Slate Edge offers an 18-month 0 percent intro APR on purchases and balance transfers, plus an APR reduction each year you pay on time and spend $1,000. The Diamond Preferred's 21-month transfer window is longer but limited to balance transfers, while Slate Edge's 18 months covers both purchases and transfers. Pick based on which use case matters more.
Frequently Asked Questions
How long is the Citi Diamond Preferred's 0 percent intro APR?
21 months on balance transfers from the date of first transfer, and 12 months on purchases from account opening. After that, the variable regular APR applies. Confirm current terms on Citi's site before applying.
What credit score do I need for the Citi Diamond Preferred?
Citi typically approves applicants with good to excellent credit, generally a FICO score of 690 or higher. A clean payment history and low credit utilization help your odds.
What is the balance transfer fee?
5 percent of each transfer, with a $5 minimum. On a $5,000 transfer, that is $250 upfront, which is usually still far less than the interest you would pay on a high-APR card over the same period.
Does the Diamond Preferred earn rewards?
No. The card has no rewards program, no welcome bonus, and no cash back. It is built for balance transfers, not everyday spending. If you want rewards, look at the Citi Strata Premier or another rewards card.
