About this calculator
Outsourced medical billing services typically charge 4-9% of collections, which sounds cheap compared to salaries but scales directly with revenue — a growing practice can end up paying more to an outsourced biller than an in-house team would cost at the same collections level. This calculator compares the percentage-fee model against fully-loaded in-house billing staff cost (salary, benefits, software, training) at your actual collections volume, and shows the breakeven collections level where the two options cost the same. It also estimates the value of expected denial-rate and days-in-AR improvement, since a good billing service often improves collections enough to more than offset its fee, while a mediocre in-house team can quietly cost more in lost revenue than its salary line suggests.

FAQ
What's a normal outsourced billing fee?
Most services charge 4-9% of collections, with smaller practices and specialties requiring more manual work (behavioral health, PT) at the higher end and high-volume straightforward specialties negotiating lower. Always confirm whether the fee is based on collections or gross charges — collections-based is standard and aligns incentives better.
Why would an outsourced service improve collections at all?
Dedicated billing companies specialize in payer-specific denial patterns and often have better claim-scrubbing software and follow-up cadence than a generalist in-house biller managing multiple duties. A realistic lift is 2-5% of collections from cleaner claims and faster denial turnaround, though this varies a lot by how well the current in-house process runs.
At what practice size does in-house billing typically make more sense?
Above roughly $2.5-3 million in annual collections, the percentage fee on outsourced billing usually exceeds what a well-run in-house team costs, assuming you can hire and retain skilled billers. Below that, the fixed cost of an in-house team is hard to justify unless billing complexity is unusually high.
Does outsourcing eliminate all in-house billing work?
No — someone still needs to handle patient billing questions, post payments, and manage the relationship with the outsourced service. Budget for at least a part-time internal point person even with full outsourcing.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
