Combine two VA disability ratings in seconds using the same whole-person formula VA uses — not simple addition. Free, no sign-up.
It's the single most common mistake veterans make estimating their own rating: adding two ratings together like 50% + 30% = 80%. VA doesn't work that way. Under 38 CFR §4.25, VA rates the whole person — each new disability is combined against your remaining non-disabled percentage, not your full percentage. Two 50% ratings combine to 75%, not 100%.
Method: VA's official Combined Ratings Table formula (38 CFR §4.25) · Deterministic calculation
| Rating 1 | Rating 2 | Combined (rounded) |
|---|---|---|
| 50% | 30% | 65% → 70% |
| 70% | 40% | 82% → 80% |
| 90% | 10% | 91% → 90% |
This quick check combines two ratings only and does not apply the bilateral factor. See the full calculator below for 3+ disabilities, bilateral factor, monthly pay, and back pay.
This quick check handles two ratings — useful for a fast gut-check, but most real claims involve more moving parts: three or more disabilities, a bilateral factor for paired-limb conditions, and turning your final percentage into an actual monthly payment amount.

VA rates the whole person, not the sum of parts. Under 38 CFR §4.25, each additional rating is applied to your remaining, non-disabled percentage rather than added directly — two 50% ratings combine to 75%, not 100%.
Combined = combined + (100 - combined) x (next rating / 100), applied one rating at a time from highest to lowest, then rounded to the nearest 10 at the very end (values ending in .5 round up).
Only at the end. A common mistake is rounding the running total after each disability is combined — VA's official Combined Ratings Table only rounds the final result.
Under 38 CFR §4.26, disabilities affecting paired limbs (both arms or both legs) are combined together first, then that sub-total gets a 10% bump before being combined with your other ratings. This quick check does not apply the bilateral factor — use the full calculator above for that.
Yes, but the dollar amount isn't a simple percentage of a base rate — VA publishes fixed monthly payment tables per rating percentage and dependent status. The rating percentage alone doesn't tell you the payment amount.
This quick check only combines two ratings. For three or more disabilities, plus the bilateral factor and monthly pay lookup, use the full calculator above.
