Clinical documentation cost calculator
Compare buying a documentation API against buying speech-to-text and building the rest, at your own volume and with your own labour cost.
Short answer
What does an AI scribe integration actually cost per encounter?
At 18,900 encounters a month, a documentation API at $1.20 per encounter costs about $1.60 per encounter all-in, against $1.76 for buying speech-to-text and building the documentation layer with 2 engineers. API list price is rarely the deciding term; sustained engineering load is.

Your assumptions
Active users generating encounters.
Ambulatory primary care typically 16-24.
21 is a normal full-time month.
Recorded duration, not appointment length.
Use your quoted rate; most vendors do not publish one.
Medical speech-to-text list rates are usually published.
Full-time equivalents, sustained not peak.
Salary plus employment cost and overhead.
Modelled monthly cost
| Line | Buy documentation API | Buy ASR and build |
|---|---|---|
| Vendor API spend | $22,680 | $3,175 |
| Engineering load | $7,500 | $30,000 |
| Monthly total | $30,180 | $33,175 |
| Per encounter | $1.60 | $1.76 |
Volume: 18,900 encounters and 264,600 audio minutes per month.
How to read the output
Two numbers matter, and neither of them is the API rate.
The first is the crossover point: below a certain monthly volume, engineering load dominates so heavily that buying documentation wins even at a high per-encounter rate. Above it, per-encounter pricing begins to matter and negotiating leverage becomes real. Find your crossover before you negotiate, not after.
The second is the sustained engineering figure. Teams routinely model the build as a project and forget that a documentation layer touching charts requires permanent staffing for monitoring, model changes, template requests and safety review. Setting engineers to zero after launch is the single most common error in these models.

Frequently asked questions
- How much does an AI scribe API cost per encounter?
- Scribe APIs are typically priced per encounter or per minute of audio, and most vendors in this category do not publish rates. Speech-to-text engines usually publish per-minute pricing. The calculator below models both so the comparison is like-for-like at your own volume.
- Why include engineering cost in a vendor comparison?
- Because the cheapest API can be the most expensive architecture. Buying raw speech-to-text shifts note generation, review workflow and clinical-safety ownership onto your team, and that labour is a recurring line item, not a one-off. Integration effort model.
- What is usually missing from a vendor's quote?
- Per-customer EHR enablement, app review cycles, clinician support load, monitoring and incident handling for note quality, and the ongoing clinical review process once notes reach charts. Build vs buy.
