All three cards advertise 21 months at 0% APR, but only two apply it to both purchases and transfers.
November 5, 2026
If you search for a balance transfer card right now, there's a good chance you'll see the Chase Slate®, Citi® Diamond Preferred® Card and Wells Fargo Reflect® Card featured again and again. With each one advertising a 0% intro APR for up to 21 months, it's tempting to treat them as interchangeable.
A closer look at the fine print shows how different these three offers are. The 21-month clock doesn't apply to the same balances or come with the same deadlines on all three cards.
That matters more than ever: credit card balances rose by $21 billion to $1.26 trillion in the second quarter of 2026, according to the Federal Reserve Bank of New York. For anyone carrying part of that debt, picking the card whose terms fit your timeline can be the difference between paying it down interest-free and paying interest again.
The short version: The Citi® Diamond Preferred® Card gives you 0% on balance transfers for 21 months on Balance Transfers, but only 12 months on Purchases on purchases. The Wells Fargo Reflect® Card offers 21 months from account opening on purchases and 21 months from account opening on qualifying balance transfers on balance transfers, provided you complete eligible balance transfers within 120 days of opening the account. The Chase Slate® puts new purchases and balance transfers on the same clock, 21 months on Purchases and 21 months on Balance Transfers respectively, and its published terms don't carry a separate transfer completion deadline the way Citi's and Wells Fargo's do. That's a real structural difference, not marketing language.
Feature | Chase Slate® | Citi® Diamond Preferred® Card | Wells Fargo Reflect® Card |
|---|---|---|---|
Intro APR: Purchases | 0% Intro APR for 21 months on Purchases | 0% for 12 months on Purchases | 0% intro APR for 21 months from account opening |
Intro APR: Balance transfers | 0% intro APR for 21 months on Balance Transfers | 0% for 21 months on Balance Transfers | 0% intro APR for 21 months from account opening on qualifying balance transfers |
Transfer completion deadline | None specified in published terms | Within 4 months of account opening for the intro rate and fee | Within 120 days of account opening |
Balance transfer fee | $5 or 5% of each transfer, whichever is greater | 3% (min. $5) within the first 4 months; 5% (min. $5) after | 5% of each transfer (min. $5) |
Annual fee | $0 | $0 | $0 |
Ongoing APR: Purchases (variable) | 18.24% - 28.24% Variable | 17.24%-27.99% | 17.24%, 23.74%, or 28.99% Variable APR |
Ongoing APR: Balance transfers (variable) | 18.24% - 28.24% Variable | 17.24%-27.99% | 17.24%, 23.74%, or 28.99% Variable APR |

The Chase Slate® is a no-frills card issued by JPMorgan Chase Bank with an annual fee of $0. Chase discontinued the original Slate card in 2020 and reintroduced it in 2026 with a longer intro offer than the version it replaced.
What sets the Chase Slate® apart in this comparison is how the offer is structured. It puts new purchases and balance transfers on the same intro clock, 21 months on Purchases on purchases and 21 months on Balance Transfers on balance transfers, both at 0% Intro APR , starting from account opening. Chase's published terms don't call out a separate window for completing a transfer. Unlike Citi's 4-month cutoff or Wells Fargo's 120-day rule, there's no second deadline to track alongside the intro period itself.
The trade-off is that the card has no rewards program and few extra perks. Its balance transfer fee ($5 or 5% of each transfer, whichever is greater) applies from the first transfer, and it matches the fee Citi charges once its own intro fee window closes. The card's advantage is how long the intro APR lasts on both purchases and balance transfers, not a lower fee.

The Wells Fargo Reflect® Card carries an annual fee of $0 and is built around its intro APR window, with one perk the other two cards don't offer: cellphone protection of up to $600 (up to two claims in a 12-month period, subject to a deductible) when you pay your monthly cellphone bill with the card.
At first glance, the Wells Fargo Reflect® Card matches the Chase Slate®: you get 0% intro APR for 21 months from account opening on purchases and 21 months from account opening on qualifying balance transfers on qualifying balance transfers. However, eligible balance transfers have to post within 120 days of opening the account to get the intro rate. Miss that window and a transfer still carries the 5% fee but may not get the promotional APR, leaving the purchase intro period as the main benefit still in play.
That 120-day rule means this card rewards speed. If you're consolidating balances from several cards, the Wells Fargo Reflect® Card can work just as well as the Chase Slate®, but only if you get everything transferred before the clock runs out.
Pros | Cons |
|---|---|
Matches the Chase Slate® intro length: 21 months from account opening on purchases and 21 months from account opening on qualifying balance transfers on transfers | Balance transfers must post within 120 days of account opening to get the intro rate |
Cellphone protection up to $600, up to two claims per 12 months | No rewards program |
Annual fee of $0 | Missing the 120-day window limits the benefit to purchases only |

The Citi® Diamond Preferred® Card is another popular balance transfer and debt consolidation tool, with an annual fee of $0. It doesn't have a rewards program, but it includes Citi Flex Pay, which lets cardholders split eligible purchases of $75 or more into fixed monthly payments, plus free access to your FICO Score.
The card offers 0% on balance transfers for 21 months on Balance Transfers, as long as transfers are completed within 4 months of opening the account, at an intro fee of 3% (minimum $5). Transfers after that window carry a 5% fee instead. Its intro APR on purchases runs 12 months on Purchases, a noticeably shorter window than the other two cards offer.
Because purchases and transfers aren't on the same clock, the Citi® Diamond Preferred® Card is best suited to people who mainly want to park an existing balance and pay it down, rather than those planning to rely on 0% financing for new spending over the next year and a half.
Pros | Cons |
|---|---|
0% on balance transfers for 21 months on Balance Transfers, matching the other two cards | Purchase intro APR runs only 12 months on Purchases, the shortest of the three |
Lower intro balance transfer fee (3%) if completed within 4 months | The lower fee requires hitting the 4-month deadline |
Citi Flex Pay for splitting large purchases; free FICO Score access | No rewards program |
Key Features:

All three cards share a few basics: no annual fee, a long intro APR window and issuers that report to all three credit bureaus. From there, the right pick depends on timing and how you plan to use the card.
Want the longest runway on both new spending and an existing balance, with the fewest strings attached? The Chase Slate® offers matching intro terms, 21 months on Purchases on purchases and 21 months on Balance Transfers on transfers, and no separate transfer deadline, which makes it the simplest of the three to plan around.
Can you move your balance within 120 days of opening the account? The Wells Fargo Reflect® Card offers 21 months from account opening on purchases and 21 months from account opening on qualifying balance transfers on transfers, plus cellphone protection. It's worth a look if you can hit that window.
Mainly consolidating an existing balance and not counting on 0% purchases past the first year? The Citi® Diamond Preferred® Card's 21 months on Balance Transfers transfer window still competes, even with its shorter 12 months on Purchases purchase offer.
If you've never moved a balance before, our guide on how to do a balance transfer walks through the process step by step.
Whichever card you choose, there are steps you can take to come out ahead. Leslie H. Tayne, Esq., of Tayne Law Group says the most important factors when choosing a balance transfer card are the full cost of the transfer and your own repayment plan. That includes the terms of the promotion and the variable APR that applies once it ends, especially if you can't repay the debt within the promotion window. A credit card payoff calculator can show the monthly payment you'd need to clear the balance in time.
A balance transfer card can certainly help you get back on your feet, but knowing how much it will cost you in total to repay the debt is important before signing up.
Enright also suggests one more step before applying for a new card.
"Since the best rates and terms go to those with the best credit scores, you may want to check your score to get a better idea of what you can qualify for," he says. "Many banks and credit unions offer them to customers at no charge."
Personal finance expert Clarissa Moore of Clarissa Explains Money says the biggest balance transfer mistake she's seen with clients isn't financial but psychological: they treat the transfer like they've paid off the debt, when all they did was move it.
Some people forget they have payments since it's a new debt, some people forget to pay it off in time and get hit with more fees, and some people rack up more debt on the credit card they paid off when they transferred the balance. A balance transfer only works if you stop new spending, create a plan, and follow it.
The annual fee is $0 on the Chase Slate®, $0 on the Citi® Diamond Preferred® Card and $0 on the Wells Fargo Reflect® Card.
Any remaining balance starts accruing interest at the card's ongoing variable APR, which depends on your creditworthiness: 18.24% - 28.24% Variable on purchases and 18.24% - 28.24% Variable on balance transfers for the Chase Slate®, 17.24%-27.99% and 17.24%-27.99% for the Citi® Diamond Preferred® Card, and 17.24%, 23.74%, or 28.99% Variable APR and 17.24%, 23.74%, or 28.99% Variable APR for the Wells Fargo Reflect® Card.
Not exactly. Chase discontinued the original Slate card in 2020 and reintroduced the Chase Slate® in 2026 with a longer intro window, 21 months on Purchases on purchases and 21 months on Balance Transfers on balance transfers, than the earlier version carried.
On the Citi® Diamond Preferred® Card, yes. The fee rises from an intro 3% (within the first 4 months) to 5% afterward. The Chase Slate® and Wells Fargo Reflect® Card apply their stated transfer fee ($5 or 5%, whichever is greater, on the Chase Slate®; 5% with a $5 minimum on the Wells Fargo Reflect® Card) without a separate intro fee tier.
The terms in this article were compared directly against each issuer's own card pages as of November 2026. Ongoing variable APR ranges are based on creditworthiness and change periodically.
All three cards in this guide can save borrowers a meaningful amount of interest into next year. The difference is in what you have to do to get the full benefit.
The Citi® Diamond Preferred® Card and Wells Fargo Reflect® Card each attach a condition to their intro offer: a shorter purchase window of 12 months on Purchases on Citi's card, and a 120-day transfer deadline on Wells Fargo's. The Chase Slate® is the one card here where the intro period applies the same way to both purchases and transfers, 21 months on Purchases and 21 months on Balance Transfers, without an extra deadline in the terms. That makes it the pick of this trio for anyone who wants the longest, least conditional 0% runway available.
