Is a personal loan better than store or merchant financing?

What merchant financing is: Retailers (furniture stores, appliance dealers, dental offices, home improvement companies) partner with finance companies to offer in-store credit. Well-known examples: CareCredit (healthcare), Synchrony (retail), GreenSky (home improvement), Klarna and Affirm (e-commerce BNPL).

The deferred interest trap: Many store credit offers advertise '0% interest for 18 months' but use deferred interest - meaning interest IS accruing in the background and the full accumulated amount is charged retroactively if you carry any balance at the deadline. On a $3,000 purchase at 29.99% APR with 18 months of deferred interest, failing to pay $1 at month 18 triggers $1,350+ in retroactive interest.

True 0% buy-now-pay-later (BNPL): Newer BNPL providers like Affirm, Klarna, and Afterpay sometimes offer genuine 0% installment plans (split into 4 equal payments or 3-6 monthly payments). These are legitimately interest-free IF you qualify. However, they often report to credit bureaus and missing a payment is still a delinquency.

Personal loan advantages over store financing: Fixed rate with no deferred interest trap. Flexible use (not tied to one merchant). Longer terms available (24-84 months vs 6-24 months at stores). No surprise interest charge at the end.

When store financing can be better: If the offer is truly 0% (not deferred interest) and you are certain you will pay in full by the deadline, you avoid interest entirely. A personal loan at even 8% APR costs money; true 0% costs nothing. But the 'certain to pay off' part is the key - if there is any doubt, personal loan wins.
