Quick Summary
The VA Combined Disability Rating Calculator uses the official VA math formula from 38 CFR 4.25 to determine your overall disability percentage. VA math is not simple addition — each rating applies to the remaining "healthy" percentage.
- VA math formula: Combined = 100% − (100% − R₁) × (100% − R₂) × ... then rounded to nearest 10%
- Example: 50% + 30% = 65% (rounds to 70%), not 80%. The 30% applies to the remaining 50% of healthy capacity
- Bilateral factor: Paired limb disabilities (both arms, both legs) get a 10% bonus added to the bilateral combined value before final combination
- Compensation: A 70% rating pays $1,808.45/month ($21,701/year) tax-free for a veteran alone. With spouse: $1,961.45/month
- Tax-free: All VA disability compensation is exempt from federal and state income tax under 38 U.S.C. § 5301
- Dependents: At 30%+ ratings, additional monthly amounts apply for spouse, children, and dependent parents

What's the combined VA disability rating for 50% + 30% + 20% in 2026?
Ratings of 50% + 30% + 20% do not add to 100% — under 38 CFR 4.25 "VA math," they combine to an exact 72%, rounded to 70%. A 70% rating pays a veteran alone $1,808.45/month tax-free ($21,701/year) under the 2026 VA compensation schedule (effective Dec 1, 2025). The method: arrange ratings highest to lowest, then apply each percentage to the remaining healthy body, not by addition.
| Step | Calculation | Remaining Healthy |
|---|---|---|
| Start | 100% healthy body | 100% |
| Apply 50% (highest) | 100 − (100 × 50%) | 50% |
| Apply 30% to remaining | 50 − (50 × 30%) | 35% |
| Apply 20% to remaining | 35 − (35 × 20%) | 28% |
| Combined Exact | 100 − 28 | 72% |
| Rounded to nearest 10% | 72 → 70 | 70% |
| Monthly Compensation | 2026 VA rate (veteran alone) | $1,808.45 |
| Annual (Tax-Free) | $1,808.45 × 12 | $21,701 |
Simple addition gives the wrong answer: 50 + 30 + 20 = 100% (clinically impossible). VA math produces 72% → 70% — a meaningful difference because the next lower rating (60%) pays only $1,435.02/month (a $373 monthly gap). If two disabilities affect paired extremities (arms/legs/eyes/ears), the bilateral factor adds 10% before combining — potentially pushing the final rating into a higher 10% bracket. Dependents at 30%+ add further monthly amounts.

How VA Math Works (2026 Combined Rating Formula)
Combined = 100% − (100% − Rating₁) × (100% − Rating₂) × ... → round to nearest 10%
Each disability applies to remaining "healthy" percentage, not the original 100%. This is why 50% + 30% = 65% (rounds to 70%), not 80%.
Example: Three Disabilities (50%, 30%, 20%)
| Step | Action | Remaining Healthy | Combined So Far |
|---|---|---|---|
| 1 | Start with highest: 50% | 50% | 50% |
| 2 | Apply 30% to remaining 50%: 30% × 50% = 15% | 35% | 65% |
| 3 | Apply 20% to remaining 35%: 20% × 35% = 7% | 28% | 72% |
| 4 | Round 72% to nearest 10% | — | 70% |
Simple addition would give 100%, but VA math gives 70%. The difference is $2,130/month ($3,938.58 vs $1,808.45).
Why VA Math Uses This Formula
The VA combined rating system recognizes that each additional disability affects a progressively smaller portion of remaining function. A veteran who is already 50% disabled has only 50% of functional capacity remaining — a new 30% disability affects that remaining capacity, not the original 100%. This "whole person" approach from 38 CFR 4.25 prevents combined ratings from exceeding 100%.
Bilateral Factor: Paired Limb Bonus (38 CFR 4.26)
The bilateral factor is an additional calculation that benefits veterans with disabilities affecting both sides of paired body parts — both arms, both legs, or paired skeletal muscles (like both shoulders or both hips).
Step 1: Combine bilateral ratings using VA math
Step 2: Add 10% of that combined value
Step 3: Use adjusted value in final combination with other disabilities
Example: Bilateral Knee Disabilities
| Step | Calculation | Result |
|---|---|---|
| 1 | Right knee 30% + Left knee 20% via VA math | 44% combined |
| 2 | Bilateral factor: 44% × 10% | +4.4% |
| 3 | Adjusted bilateral value | 48.4% |
| 4 | Combine with other disabilities (e.g., PTSD 50%) | 74.2% → 70% |
2026 VA Disability Pay Rates (All 10 Levels)
VA disability compensation is 100% tax-free — exempt from both federal and state income taxes under 38 U.S.C. § 5301. Rates are adjusted annually based on the Social Security COLA.
| Rating | Veteran Alone | With Spouse | Annual (Tax-Free) |
|---|---|---|---|
| 10% | $180.42 | N/A | $2,165 |
| 20% | $356.66 | N/A | $4,280 |
| 30% | $552.47 | $617.47 | $6,630 |
| 40% | $795.84 | $882.84 | $9,550 |
| 50% | $1,132.90 | $1,241.90 | $13,595 |
| 60% | $1,435.02 | $1,566.02 | $17,220 |
| 70% | $1,808.45 | $1,961.45 | $21,701 |
| 80% | $2,102.15 | $2,277.15 | $25,226 |
| 90% | $2,362.30 | $2,559.30 | $28,348 |
| 100% | $3,938.58 | $4,158.17 | $47,263 |
Rates effective December 1, 2025. 10-20% ratings do not include dependent additions. All VA disability compensation is tax-free at federal and state level.
Tax-Free Equivalent Value
Because VA disability is tax-free, its actual value is higher than it appears. To earn the equivalent of a 100% VA disability payment ($47,263/year), a veteran in the 22% tax bracket would need to earn approximately $60,594 in taxable salary. In a state like California with 9.3% state tax, the equivalent salary jumps to $68,796.
| Rating | Annual Tax-Free | Equiv. Salary (22% bracket) | Equiv. Salary (CA 9.3%) |
|---|---|---|---|
| 50% | $13,595 | $17,429 | $19,789 |
| 70% | $21,701 | $27,822 | $31,589 |
| 100% | $47,263 | $60,594 | $68,796 |
VA Dependent Pay: Spouse, Children & Parents
Veterans rated 30% or higher receive additional monthly compensation for each qualified dependent. Those rated 10-20% do not receive dependent additions.
| Dependent Type | 30% | 50% | 70% | 100% |
|---|---|---|---|---|
| Spouse | +$65 | +$109 | +$153 | +$219.59 |
| Child under 18 (each) | +$32 | +$54 | +$75 | +$107.72 |
| Child 18+ in school (each) | +$104 | +$174 | +$243 | +$347.54 |
| 1 dependent parent | +$45 | +$75 | +$105 | +$150.54 |
| 2 dependent parents | +$84 | +$141 | +$197 | +$282.24 |
| Spouse Aid & Attendance | +$56 | +$94 | +$131 | +$187.86 |

How to Maximize Your VA Disability Rating
Understanding VA math helps you strategize which conditions to claim and how to document them effectively:
Key Strategies
- Claim all conditions: Even a 10% rating for a minor condition can push your combined rating past a rounding threshold. A veteran at 64% combined who adds a 10% condition jumps to 67.6% — rounding to 70% ($373/month more)
- Request bilateral factor: If you have conditions affecting both sides (both knees, both shoulders), ensure the bilateral factor is applied. Some rating decisions miss this
- Secondary conditions: Conditions caused by a service-connected disability are also ratable. Back pain from a service-connected knee injury, depression from chronic pain — these are secondary claims
- TDIU at 70%: If you cannot work due to service-connected disabilities and have at least one 60%+ rating (or combined 70% with one 40%+), you may qualify for Total Disability based on Individual Unemployability (TDIU) — paid at the 100% rate
- Increase claims: If a condition has worsened, file for an increase. Medical evidence of deterioration can raise your rating

VA Combined Disability Rating Formula (38 CFR 4.25)
The VA combined disability rating is calculated using the "whole person" method codified in 38 CFR 4.25. Disabilities are arranged in order of severity from highest to lowest. The formula applies each subsequent disability to the remaining non-disabled percentage: Combined = 100 − [(100 − R₁) × (100 − R₂) × (100 − R₃) × ...]. For example, ratings of 60%, 40%, and 20%: remaining = 100 × 0.40 × 0.60 × 0.80 = 19.2%, combined exact = 80.8%, rounded to 80%. Without VA math, simple addition would give 120% (impossible). The final combined value is rounded to the nearest 10% — values ending in 5 or above round up (e.g., 65% → 70%), values below 5 round down (e.g., 64% → 60%). This rounding can mean a significant difference in monthly compensation: 70% pays $1,808.45/month while 60% pays $1,435.02 — a $373.43 difference from a single percentage point.
VA Bilateral Factor for Paired Limb Disabilities (38 CFR 4.26)
The bilateral factor under 38 CFR 4.26 applies when a veteran has service-connected disabilities affecting both paired extremities (both arms, both legs, or paired skeletal muscles). After combining the bilateral disabilities using standard VA math, 10% of the bilateral combined value is added (not combined) to the result before proceeding with further combinations of non-bilateral disabilities. For example, if a veteran has 30% right knee and 20% left knee: bilateral combined = 44%, bilateral factor = 44% × 10% = 4.4%, adjusted bilateral = 48.4%. This adjusted value then combines with other non-bilateral disabilities. The bilateral factor always benefits the veteran — per 38 CFR 4.26(b), if excluding a bilateral disability from the bilateral factor calculation produces a higher final rating, the VA must use whichever calculation is most favorable.
2026 VA Disability Compensation Rates
VA disability compensation for 2026 (effective December 1, 2025) ranges from $180.42/month at 10% to $3,938.58/month at 100% for a veteran with no dependents. All VA disability compensation is completely tax-free under 38 U.S.C. § 5301 — exempt from both federal and state income taxes. A 100% rated veteran receives $47,263 per year tax-free, equivalent to approximately $54,535-$60,594 in pre-tax salary depending on tax bracket. Veterans rated 30% or higher receive additional compensation for dependents: $65/month per spouse at 30%, increasing to $219.59 at 100%. Each child under 18 adds $32-$107.72/month depending on rating. Dependent parents add $45-$150.54 each. Compensation is adjusted annually based on the Social Security COLA. VA disability payments are not counted as income for purposes of SNAP, Medicaid, or other means-tested benefit programs.
Additional Benefits by VA Disability Rating Level
Beyond monthly compensation, VA disability ratings unlock additional benefits at key thresholds. At 10%+: access to VA healthcare priority group, property tax exemptions in many states, and Space-A military flights. At 30%+: dependent additions to compensation, additional clothing allowance. At 50%+: CHAMPVA healthcare for dependents (if ineligible for TRICARE), increased hiring preference for federal jobs. At 70%+: vocational rehabilitation (Chapter 31) eligibility, state vehicle registration and driver license fee waivers in many states. At 100% (or TDIU): full VA healthcare for all conditions, dental care, CHAMPVA for dependents, state property tax exemptions up to 100% in many states, commissary and exchange access, and Special Monthly Compensation (SMC) eligibility for loss of use or need for aid and attendance. Veterans rated 100% P&T (Permanent and Total) also qualify for Chapter 35 Dependents Educational Assistance (DEA) providing up to 36 months of education benefits to dependents.
