Deferred Interest
Also known as: same-as-cash financing, no-interest if paid in full
A financing arrangement where interest accrues during a promotional period but is waived if you pay the full balance by the deadline. If even $1 remains unpaid at the deadline, the entire deferred interest - often at 26%-30% APR - is charged retroactively.
Full definition
Deferred interest is commonly used by retailers, healthcare providers, medical credit cards (CareCredit), and home improvement contractors. The marketing language 'same as cash' or 'no interest if paid in full in 12 months' signals a deferred interest arrangement. Why it is risky: Unlike a true 0% APR promotion where interest simply does not accumulate, deferred interest runs a hidden interest clock behind the scenes at the full rate (typically 26%-30% APR). The entire accumulated interest is waived only if you pay the full original balance by the promotional end date. If you have $1 remaining, you owe all the deferred interest retroactively. Example: $3,000 furniture purchase on same-as-cash 18-month financing at 29.99% APR. If you pay $2,990 by the end of month 18 but still owe $10, you are charged approximately $1,350 in deferred interest (18 months x 29.99% / 12 x $3,000 average balance). The $10 remaining cost you $1,350. How to handle deferred interest financing safely: Set a calendar reminder for 60 days before the deadline. Arrange your budget to pay the full balance at least 30 days early to avoid any last-minute payment timing issues. Better alternatives for most borrowers: A personal loan with a fixed rate eliminates the deferred interest risk entirely. A true 0% APR balance transfer card (not deferred interest) is also safer.

- APR (Annual Percentage Rate)APR is the yearly cost of borrowing, expressed as a percentage of the loan amount. It includes interest plus most lender fees, so it's a more complete measure of cost than the interest rate alone.
- Interest rateThe interest rate is the percentage of the loan balance charged per year as interest, excluding fees. It is a component of, but smaller than, the APR.
- Fixed interest rateA fixed rate stays the same for the entire life of the loan, so the monthly payment never changes. Most U.S. personal loans are fixed-rate.
- Variable interest rateA variable rate can change over the life of the loan, usually tied to an index like the prime rate. Monthly payment can rise or fall.
- Prime rateThe prime rate is the benchmark interest rate U.S. banks publish for their most creditworthy commercial customers. Many consumer rates are quoted as prime + a margin.
- Loan termThe loan term is how long you have to repay the loan, usually expressed in months. Common personal-loan terms are 24, 36, 48, 60, and 72 months.
