Wondering why your VA combined rating doesn’t add up the way you expect? That’s because the VA uses “VA Math”—a percentages-of-percentages system that almost always leaves Veterans scratching their heads.
Instead of just adding your ratings together, the VA calculates each new rating against the part of you they still consider “healthy.” That’s why 1 + 1 doesn’t equal 2 when it comes to your disability rating.
That’s also why we’ve built our own VA Rating Calculator right here on this page—to help you see exactly how the numbers work.
But the calculator is just the start. A strong claim isn’t just about math—it’s about medical evidence.
Take the next step: Schedule your free case evaluation today and let Valor Health build the evidence you need for the rating (and compensation) you’ve earned.
2026 rates • Combined ratings (incl. bilateral factor) • Estimated monthly compensation with dependents
Tip: If you add both left + right (arms or legs), the calculator applies the bilateral factor where applicable.
