About VA Disability Calculator
A free calculator built around one problem: most VA rating tools either round off the combined-ratings math or make you hand over your phone number before showing a number at all.
Why this calculator exists
VA disability math isn’t simple addition — ratings combine using 38 CFR § 4.25’s Table I, not a straight sum, and dependent pay, the bilateral factor, and SMC each change the answer in ways that are easy to get wrong by hand. VA Disability Calculator runs the same math VA uses, shows the full combined-ratings table, and gives you a number in seconds — no account, no phone number, no email required to see your result.
We keep the site free to use and support it independently. See how we source and verify every figure for exactly where the numbers come from.
Methodology & accuracy
This calculator is a direct software implementation of the mathematical algorithms defined in 38 CFR § 4.25 (Combined Ratings Table) and 38 CFR § 4.26 (Bilateral Factor), using the official 2026 VA Compensation Rate Tables published by the U.S. Department of Veterans Affairs.
Every rating and pay figure is produced by the same tested code shown working on this page — not written or estimated by hand. See the editorial standards page for sourcing details and the rates changelog for when figures were last verified.
