What percentage do medical bill negotiators charge?
Most medical bill negotiators charge 10% to 35% of the amount they save you. This is a contingency fee, which means the cost is tied directly to your savings: if your bill is not reduced, you owe nothing. That structure keeps the negotiator’s incentive aligned with yours, because they only get paid when you do.
The percentage often depends on the size of the bill. Some services, like Resolve, use a tiered scale where the rate drops on larger savings. Others, like CareRoute and Goodbill, apply a flat percentage but cap the total fee, so your effective rate falls as savings grow.
Are there upfront fees, deposits, or minimum bill sizes?
- No upfront cost (most services): CareRoute and Goodbill charge $0 upfront and take a share of savings only after your bill is reduced.
- Refundable deposits: Resolve requires a $249 to $499 deposit to start, which is refundable, and sets a $5,000 minimum bill size.
- Fee caps: a cap matters most on large bills. CareRoute and Goodbill cap fees at $1,000, so a big reduction does not mean a runaway fee. Resolve has no stated cap.
- Free options: Dollar For, a nonprofit, charges nothing, but it only helps with charity care applications at nonprofit hospitals and does not negotiate bills.
How CareRoute Bill Defense pricing works
CareRoute charges 25% of savings (or 18% for CareRoute app premium subscribers), capped at $1,000. There is no upfront cost, and no fee at all if we cannot reduce your bill. Because of the cap, your effective rate keeps dropping the more we save you.
Example: a $3,500 bill
We reduce it to $2,500, saving you $1,000. Your fee is $250 (or $180 as a premium subscriber). You keep $750 or more of the savings.
Example: a $20,000 bill
We reduce it by $8,000. A straight 25% would be $2,000, but the $1,000 cap applies, so your fee is just $1,000. That is an effective rate of about 12.5%.
Is a medical bill negotiation service worth the cost?
For most people with bills over a few hundred dollars, yes. An estimated majority of medical bills contain errors, and professional negotiators typically reduce bills by 30% or more through error correction, financial assistance, insurance disputes, and direct negotiation. Because the fee is a percentage of savings with no upfront cost, the math is simple: you only pay if you come out ahead.
The main reason not to use a service is if you have the time and confidence to negotiate yourself, which is free.
