Deferred interest is not the same as no interest. Almost nobody reads the fine print.
Linda, 39, needed $2,800 of dental work — crowns and a root canal. Her dentist's office offered CareCredit: "18 months interest-free financing! Just make the minimum payments and you're covered." Linda signed up. The monthly minimum was about $60.
She paid faithfully for 18 months. On month 19, her statement showed a $2,400 charge — "accrued interest."
"They said interest-free. I paid every month. Where did $2,400 come from? This doesn't make sense." Linda called CareCredit's customer service. They explained that the promotional period had ended and the deferred interest had been applied.
She hadn't read the fine print. Almost nobody does.
"Interest-free" medical financing cards like CareCredit typically use deferred interest — not true 0% APR. The difference is enormous. With true 0% APR, you only owe interest on whatever balance remains if you don't pay it off. With deferred interest, the interest accrues on the full original amount from day one — it's just hidden. If you don't pay the full balance before the promotional period ends, the entire accrued amount hits your account at once.
A $2,800 balance at 26.99% APR over 18 months generates approximately $2,300-$2,500 in deferred interest — nearly the same as the original bill. Better alternatives: negotiate a direct payment plan with the provider (often 0% interest, no fine print), apply for charity care first, or use a personal loan at a fixed lower rate.
Linda avoided the $2,400 deferred interest trap on her next procedure by simply asking one question before signing. The direct payment plan her dental office offered was better in every way — and she only found out it existed because she asked.
