The widget uses the same deterministic combined-rating engine as UnderstandMyRating. That engine is golden-tested against the published combined ratings table. It applies the combined-rating method in 38 CFR §4.25 and the bilateral factor in 38 CFR §4.26, then shows each step.

The calculator is free to embed on any site serving veterans. Do not present it as your own product or remove its link to understandmyrating.com. We may update the widget, and improvements appear automatically wherever it is embedded. The widget is provided without a guarantee or warranty.
