What the Citi Diamond Preferred Card offers for balance transfers
The Citi Diamond Preferred Card offers an introductory period with no interest on balance transfers — the length of that period and any transfer fee depend on your creditworthiness and the current offer. You move an existing balance from another card to this one, and during the introductory window, you pay only principal, not interest. After the introductory period ends, a standard purchase and balance transfer rate applies.
The card is designed for people who carry a balance and want breathing room to pay it down without interest accumulating. It is not a loan or a new source of money — it is a way to move debt you already owe to a card with different terms.
Key Takeaways
- The introductory interest-free period on balance transfers varies by offer and your credit profile, so you will see the exact terms before you complete the transfer.
- Citi charges a balance transfer fee, usually a percentage of the amount you move, which is added to your new balance on the card.
- You must transfer the balance within a set window from when you open the account — typically 4 months, though this varies by offer.
- During the introductory period, only payments above the minimum go toward principal; minimum payments cover interest-free principal and fees.
- After the introductory period ends, any remaining balance carries the card's standard APR, which can be 15% to 25% or higher depending on your credit.
How to initiate a balance transfer with Citi Diamond Preferred
You start by opening the Citi Diamond Preferred Card account. During the process, you will be asked whether you want to transfer a balance. If you are approved, Citi will provide you with a balance transfer check or a direct transfer option to move money from your old card to the new one.
You can also transfer after opening the account by logging into your Citi account online or calling the customer service number on the back of your card. Citi will ask for the name of the card issuer you are transferring from, your account number with that issuer, and the amount you want to move. The transfer typically posts to your new Citi card within 7 to 14 business days.
Keep in mind that you must complete the transfer within the promotional window — usually 4 months from account opening. Any balance transfer initiated after that date will not receive the introductory rate.
Balance transfer fees and how they affect your payoff plan
Citi charges a balance transfer fee on the amount you move. This fee is typically 3% to 5% of the transfer amount, though the exact percentage depends on the current offer and your credit profile. The fee is added to your balance on the new card, so if you transfer $5,000 with a 4% fee, your new balance is $5,200.
The fee is important to factor into your payoff math. If you transfer $5,000 at 4% ($200 fee) and have 12 months interest-free, you need to pay at least $434 per month to clear the balance before interest kicks in. If you pay only the minimum, you may not cover the fee and transferred principal within the promotional window, and the remaining balance will then accrue interest at the card's standard rate.
Compare this fee against what you are currently paying in interest on your old card. If you are paying 20% APR on a $5,000 balance, you are losing roughly $100 per month to interest alone. A $200 transfer fee plus 12 months interest-free can still save you money if you commit to paying down principal during that window.
The introductory period and what happens when it ends
The introductory interest-free period on balance transfers typically lasts 6 to 21 months, depending on the offer at the time you explore. During this time, you owe no interest on the transferred balance — only on new purchases you make with the card, which carry the standard APR from day one.
When the introductory period ends, any remaining balance on the transfer reverts to the card's standard APR. This rate is not fixed and varies based on your credit score, payment history, and current market conditions. For the Citi Diamond Preferred Card, this rate typically ranges from 15% to 25% or higher.
The math changes sharply on day one after the promotional period. A $3,000 remaining balance at 20% APR costs you $50 per month in interest alone. This is why the introductory period is a important date, not a suggestion — you should treat it as the hard stop for paying down the transferred balance.
Who this card makes sense for and who it does not
This card is useful if you carry a balance on a high-interest card and can commit to paying it down during the interest-free window. You need a credit score in the good to excellent range — typically 670 or higher — to be approved and to receive the longest introductory periods. If your score is lower, you may still be approved, but the promotional period may be shorter and the transfer fee higher.
The card does not make sense if you cannot pay down the balance before the introductory period ends. Transferring a balance you plan to carry for years just delays the problem and adds a transfer fee on top. It also does not make sense if you will continue using credit cards for new purchases while paying down the transfer — the new purchases accrue interest when ready, and you may end up with more total debt than you started with.
If you have no credit history or a very low score, you may not be approved for this card at all. In that case, a balance transfer is not an option, and you would need to explore other debt payoff strategies or credit-building approaches first.
Comparing the Citi Diamond Preferred to other balance transfer cards
Other issuers offer balance transfer cards with different terms. Some offer longer introductory periods — up to 21 months interest-free. Others charge lower transfer fees, sometimes 0% for the first 60 days after opening the account. A few offer no annual fee, while the Citi Diamond Preferred Card has no annual fee either.
The best card for you depends on your specific situation: how much you are transferring, how quickly you can pay it down, and whether you need a long runway or a low fee. If you can pay off $3,000 in 9 months, a card with a 12-month promotional period and a 3% fee may be better than one with 18 months and a 5% fee. If you are transferring $10,000 and need 18 months, the longer period matters more than the fee.
Check the terms of cards you are considering side by side: the introductory APR period length, the transfer fee percentage, the standard APR after the promotional period, and any annual fee. Calculate the total cost of each option based on your transfer amount and your realistic payoff timeline.
Steps to take before and after transferring a balance
Before you transfer, know your current balance, the interest rate you are paying, and how much you can realistically pay each month. Use this to calculate whether you can clear the transferred balance — plus the transfer fee — before the introductory period ends. If the math does not work, do not transfer.
After the transfer posts, stop using the old card. Closing it when ready can hurt your credit score slightly because it reduces your available credit, but leaving it open and unused is usually better. Set up automatic payments on the Citi card for an amount that will clear the balance before the promotional period ends. Do not make new purchases on the Citi card during the payoff period — they carry interest from day one and complicate your payoff math.
Mark your calendar for one month before the introductory period ends. At that point, check your balance and adjust your payment if needed to may support you pay off the transfer before interest kicks in. If you cannot clear it, you have time to explore other options, such as another balance transfer to a different card.
Frequently Asked Questions
Can I transfer a balance from multiple cards to the Citi Diamond Preferred?
Yes. You can transfer balances from more than one card, as long as the total does not exceed your credit limit and you complete all transfers within the promotional window. Each transfer is subject to the same balance transfer fee and introductory period.
What happens if I miss a payment during the introductory period?
A missed payment can end the introductory rate when ready, even if you are still within the promotional window. The remaining balance then reverts to the standard APR. Missing a payment also damages your credit score and may trigger a late fee. Set up automatic payments to avoid this.
Can I transfer a balance from another Citi card?
Citi generally does not allow you to transfer a balance from another Citi card to the Citi Diamond Preferred. You can transfer from cards issued by other banks — Visa, Mastercard, American Express, or Discover from any other issuer.
What is the difference between the introductory rate on transfers and on purchases?
The introductory rate applies only to the balance you transfer. Any new purchases you make with the card carry the standard APR from the first day, even during the promotional period. This is why you should not use the card for new spending while paying down the transfer.
If I pay off the balance early, do I get a refund of the transfer fee?
No. The transfer fee is non-refundable. However, paying off early means you stop accruing interest sooner, which saves you money overall. If you can pay off the balance in 6 months instead of 12, you avoid 6 months of interest that would have accrued after the promotional period.
