Under the Microscope: Uncovering what’s behind medical credit card no-interest financing.

Are you familiar with this medical credit card financing promo?
“No interest if paid in full within the 6, 12, 18 or 24 months promotional period.”

Medical credit card deferred interest financing may be inherently bad for patients not financially equipped to pay their entire balance within a defined promotional period. These are shared concerns across the industry and are currently being examined. It’s time for every dental practice to ask, “is medical credit card deferred interest financing the best experience for patients and the reputation of my practice?”

Before you offer medical credit card deferred interest promotions again, we want to give you a simple understanding of what your patients potentially face.

1. Deferred interest does NOT necessarily mean NO interest. 

A patient will have to pay interest on deferred interest financing if they don’t pay off their entire balance by the end of the promotional period. This interest accrues from the original date of purchase and is added to the balance.

Here is the definition of deferred interest according to CareCredit:

Deferred-interest financing means you won’t pay any interest if you pay your promotional balance in full by the end of the agreed-to promotional period.

Interest still accrues from the date of purchase, though, so if you don’t pay off the balance in full by the end of the promotional period, that accrued interest will be assessed and added to your balance. Depending on your purchase cost, that could mean shelling out an additional significant cost. Deferred-interest financing may also be advertised as “No Interest if Paid within X Months.1

2. Balloon interest, and interest on interest.

According to the National Consumer Law Center, deferred interest promotions can land consumers in a bad situation where they are responsible for a lump sum of interest at the expiration of the promotional period. If the consumer takes longer to pay off the remaining balance, including the interest, they begin accruing interest back on interest. 

For consumers hit with deferred interest, those charges come in one big lump sum at the expiration of the promotional period. Interest charges that might have been manageable in small pieces can result in the outstanding balance on a card increasing dramatically. Consumers who cannot pay off that huge interest charge at once then start paying interest on the back interest.2

3. Monthly minimum payments often won’t cover the amount financed.

The minimum monthly payment is typically up to 3% of the outstanding balance. A cardholder can pay the minimum each month and be on good terms within a deferred interest promotional period, but according to the Consumer Financial Protection Bureau “…minimum payments probably won’t be enough to pay off the entire balance by the end of the deferred interest period.3” This can land patients in a situation where they made all their payments on time but still owe deferred interest because their monthly minimum payment was not enough to pay off the entire balance during the promotional period.

4. Beware of late fees.

Looking beyond interest owed, many medical credit cards come with additional costs including late fees as high as $414.
