Every figure above is read from the issuer's own site or card agreement, not from comparison sites, and each row links to the source it came from with the date we last read it. Rows marked "check with issuer" have at least one figure Citi or Chase does not publish in a form we can read; we flag those rather than estimate them. Card terms change often, so confirm current terms with the issuer before you apply.

Plain English

Pay $405 a month for 21 months and clear $8,500 with no interest. Skipping a 22% card on the same balance saves you about $2,193.

Comparison ignores rewards, transfer fees, and any balance still owed at month 22. Use this as an order-of-magnitude check, not financial advice.

Editorial picks

Three picks for three different jobs

No issuer paid for these slots. Picks reflect editorial judgement based on the runway, fees, and supplementary perks that show up in the table above.

Longest runway

Reflect Card

21months at 0%

Around 21 months 0% on both purchases and BT. Cell phone protection up to $600 per claim. Solid pick if you want flexibility for new spend and old debt.

Lowest regular APR

BankAmericard

20months at 0%

Around 21 billing cycles at 0%, then the lowest fallback APR range in the table. Worth a look if there is any chance a balance survives past the intro window.

Best with rewards

Freedom Flex

15months at 0%

Around 15 months at 0% plus 1.5% to 5% cashback on every purchase. Better total value than the longest runway when your balance clears within 12 to 14 months.

0% APR: the questions you keep asking

6 questions
  1. It depends on what you are financing and how long you need. For a single large purchase you want to spread out, the longest runway available (around 21 months) wins. For someone juggling both a planned purchase and existing card debt, a balanced runway of around 21 months across both purchases and balance transfers makes more sense. For a smaller balance you can clear in a year, a shorter runway with cashback rewards probably leaves you better off overall.
