0% Balance Transfer Cards With 21 Months: The Three Longest Offers

If you're paying 20%, 25% or even 30% interest on a credit card, the single fastest change you can make is moving that balance to a 0% rate for as long as a bank will give it to you. In this video I cover the three 0% balance transfer credit card offers with the longest term I've found: 21 months, from Wells Fargo and Citi.
I go through the fee on each one, what that fee actually costs in dollars, and how the monthly payment math changes when you stretch the same balance over 21 months instead of 12.
What you'll learn
- Which three cards offer 0% on balance transfers for 21 months
- What a 5% balance transfer fee costs on a $10,000 balance
- Why the fee is usually worth it compared to 20%–30% interest
- How to figure your monthly payment so the balance is gone before the 0% ends
- What to do if you can't qualify for a 21-month offer
Why a balance transfer is the first move
Most people carrying credit card debt are throwing money away on interest every single month. The balance barely moves because a big chunk of the payment never touches principal. A 0% balance transfer stops that cold. Every dollar you send goes to the balance instead of the bank. That's why I tell people to try this first, before getting creative with other payoff strategies.
The other half of the equation is time. A 12-month 0% offer is fine, but 21 months gives you almost two years of zero interest, which means a much smaller required monthly payment to finish on schedule.
The three 21-month cards
The first is the Wells Fargo Reflect Card. No annual fee, and a 5% balance transfer fee, with 0% on the transferred balance for 21 months.
The other two are Citi cards: the Citi Simplicity Card and the Citi Diamond Preferred Card. Same structure — no annual fee, 5% balance transfer fee, and 0% for 21 months on the transfer.
I focused only on these three because 21 months is the longest term I've seen these banks offer on a 0% balance transfer. Card terms do change over time, so always confirm the current offer before you apply.
What the 5% fee really costs
A transfer fee is normal, and people get hung up on it. Here's the math. Say you have $10,000 on a high-interest card and you move it over. The 5% fee is $500, so your new balance is $10,500. Yes, your balance went up. But you're now at 0% instead of 20%, 25% or 30%. In the big scheme of things, $500 one time is nominal compared to what interest would have cost you over the same stretch, and the balance gets paid off much faster.
The monthly payment math
This is the part that matters most. Take a $1,200 balance on a 12-month 0% card. Divide $1,200 by 12 and you get $100 a month — no interest, balance gone at month 12. Same $1,200 on a 21-month card? You're closer to $60 a month. Not quite two years, but close, and the required payment drops a lot.
That lower required payment is breathing room. You can pay the minimum required amount and stay on track, or pay more and finish early.
If you can't get one of these
Not everyone will be approved for a 21-month offer. There are cards with 12, 15 and 18-month 0% terms that still beat paying 25%, and there are other routes like refinance loans. But if you can do a 0% transfer first, do it first.
Key steps
- Write down each card balance and its interest rate.
- Compare the three 21-month 0% offers and confirm current terms and fees.
- Add the transfer fee to the balance so you know the real number you owe.
- Divide that new balance by 21 to get your payoff payment.
- Run it through the credit card payoff calculator and compare it to staying put.
- Set the payment on autopay and don't put new charges on the old card.
FAQ
Is a 5% balance transfer fee too high?
On a $10,000 balance, 5% is $500 one time. Compare that to what 20%–30% annual interest costs you on the same balance and the fee usually looks small. Run both numbers before you decide — the real math on 0% cards walks through it.
What happens if I don't pay it off in 21 months?
Whatever is left starts accruing interest at the card's regular rate. That's why you divide the transferred balance by 21 up front and treat that number as a required bill, not a goal.
Can I use a 0% card with the avalanche method?
Yes. A 0% card changes which debt has the highest rate, so the order you attack can shift. I cover that in the avalanche method with a 0% card and in the step-by-step on how to do a 0% balance transfer.
Which Citi and Wells Fargo cards have a 21 month balance transfer at 0%?
The three I cover are the Wells Fargo Reflect Card, the Citi Simplicity Card and the Citi Diamond Preferred Card. Each one has no annual fee, a 5% balance transfer fee and 0% on the transferred balance for 21 months. Card terms change over time, so the current offer is worth confirming.
How do you figure the monthly payment on a 21 month 0% balance transfer?
Add the transfer fee to the balance so you know the real number you owe, then divide it by 21. In the video, $1,200 on a 12-month 0% card is $100 a month, while the same $1,200 over 21 months is closer to $60. You can pay that amount and stay on track, or pay more and finish early.
