Balance transfer.
In plain English
Balance transfer offers give you a window, often 12 to 21 months, at 0% interest on debt you move over, in exchange for a one-time fee of typically 3% to 5% of the amount. Used as designed, it's a debt-payoff accelerator: every dollar of payment hits principal during the promo. Used casually, it's a debt relocation program: the balance survives the promo and the regular APR, often 25%+, resumes on whatever's left.
01Why it matters
For someone seriously attacking card debt, a transfer can save four figures in interest. The offer's fine print (fee, promo length, what happens to new purchases, the deferred-interest trap on store cards) decides which story you get.
02The math, step by step
$6,000 at 24% APR transferred for a 3% fee ($180) to an 18-month 0% card. Paying $345/month clears it inside the window. Staying on the old card at the same payment costs roughly $1,200 in interest. The $180 fee bought a roughly $1,000 win.
Illustrative example. The amounts here are hypothetical, chosen to show how the math works, not real quoted rates or figures.
03What this is NOT
0% on transfers is usually not 0% on new purchases, and the promo often dies entirely if a payment is late. The transfer is a tool for paying debt off, not a place to store it.
