Said It Here

Are 0% interest financing plans actually a trap?

Deferred interest promotions hit you with all the accrued interest from day one if you fail to pay off the entire balance before the promo period ends. Lenders rely on this structure, alongside potential penalties for falling behind on payments, to catch borrowers unaware if they miss the payoff deadline.

“Have to read the terms. Most have gotten away from accrued interest from start date if not paid in full. Meaning, if you don't have a zero balance clear, they can tack on interest from day one and your responsible.”source ↗
