Formulary Coverage Calculator
Employer health plans pay negotiated prices for prescription drugs that are often far higher than what the Mark Cuban Cost Plus Drug Company charges — this tool measures the difference. Load your organization's drug spend data to see a projected cost comparison, or run the sample dataset to see a demonstration.

Cost Plus Drugs has built something unusual in healthcare: a pharmacy with fully transparent pricing and no middlemen. The model is straightforward—manufacturer cost, a 15% markup, and a flat pharmacist fee. What makes it especially interesting is that they publish all of this through a public API, making independent analysis possible.
I wanted to see what was possible with that open data. This tool runs entirely in your browser—no backend, no data collection, no accounts—and performs formulary coverage analysis using only publicly available APIs. Source code available upon request.
