CareCredit vs Cherry vs Walnut vs Sunbit: medical financing compared (and the deferred-interest trap).

Four major medical financing options dominate doctor and dentist offices. Each has a real strength and a real catch. CareCredit wins on acceptance and 0% promo periods but has the worst penalty if you miss a deadline. Cherry wins on soft-pull instant approval. Walnut wins on $0-down accessibility. Sunbit wins on speed-to-decision. For amounts over $10K, a personal loan usually beats all four. Here's the honest math.

CareCredit (Synchrony)

The 800-pound gorilla. Accepted at 270,000+ healthcare providers including most dentists, vision centers, dermatologists, vets, and many medical practices.

• Promotional 0% APR: 6, 12, 18, or 24 months on purchases above $200 (length varies by provider).
• Standard APR: 26.99% to 32.99% variable.
• Long-term fixed APR: 14.90%-17.90% on 24/36/48/60-month equal-payment plans (only on amounts above $1,000-$2,500).
• Credit pull: hard pull at application.
• The trap: "deferred interest" on promotional 0% plans. Miss the deadline (even by one day, even with a $1 balance), and CareCredit charges back-interest at 26.99%+ on the ORIGINAL FULL purchase amount, not the remaining balance. A $5,000 charge with 18-month 0% promo, paid off on month 19 with $500 still owed = ~$2,250 in back-interest added.

Best for: Procedures $1,000-$10,000 you can pay off comfortably WITHIN the promo window. Set auto-pay slightly above the amortized monthly amount so you finish 30 days early.

Cherry

Newer point-of-sale lender, growing fast in dental, dermatology, plastic surgery, and chiropractic.

• APR range: 0%-36% based on credit (no deferred-interest trap — interest is simple, calculated monthly).
• Credit pull: SOFT pull at application — doesn't hit your credit score.
• Terms: 3, 6, 12, 18, 24 months (occasionally longer).
• Approval amount: $200-$10,000+ depending on credit.
• The catch: the 0% rate is only for top-tier credit (740+). Mid-tier credit (~680) often sees 12-24% APR, which on a $5K loan over 24 months adds $1,200-$2,400 in interest.

Best for: Single-procedure financing $500-$5,000 when you want to check rates without dinging your credit. Honest APR you can plan around.

Walnut

Smaller player focused on $0-down monthly payments at point of care.

• $0-down: typical entry hook.
• APR range: 0%-36%.
• Soft pull at application.
• Terms: 3-24 months.
• The catch: smaller provider network than CareCredit or Cherry. May not be available at your specific clinic.

Best for: Patients with limited cash flow who can't put any money down. Negotiate the APR — first quote is often not best.

Sunbit

Instant 30-second approval, used heavily by auto repair shops + expanding into dental.

• APR range: 0%-35.99%.
• Soft pull at application.
• Terms: 3, 6, 12 months (occasionally up to 72).
• Approval amount: up to $20,000.
• The catch: shorter typical terms can mean higher monthly payments than CareCredit's 60-month plans.

Best for: Patients who need a yes/no decision fast at the front desk. Comparable to Cherry on rates, faster approval.

Personal loans (LightStream, SoFi, Prosper)

For amounts over $10K (All-on-4 dental, major surgery, fertility treatment), a personal loan usually beats medical credit cards:

• APR range: 7%-25% fixed.
• Credit pull: soft pull for rate check, hard pull at acceptance.
• Terms: 24-84 months.
• Approval amount: $5,000-$100,000.
• Why it wins: no deferred-interest trap, lower APR for good credit, longer terms = lower monthly payment, and you can use it anywhere (not provider-restricted).

Side-by-side at $5,000 / 18 months

Bottom line

1. Procedure under $5K, top-tier credit, sure you'll pay it off in 6-18 months: CareCredit 0% promo — with auto-pay set 30 days early as insurance.
2. Procedure $1K-$10K, mid-tier credit, want predictable monthly: Cherry or Sunbit fixed APR. Compare both at your provider.
3. Procedure over $10K (All-on-4, major surgery): personal loan from LightStream / SoFi / Prosper. Check rates with soft pull before committing.
4. Cash-flow tight, need $0-down: Walnut or Sunbit.
5. Always: get a written quote from the provider FIRST, then compare financing rather than letting the front desk steer you to one option.
