VA Benefit Calculator
30% + 20% disabilities: combined 40% (not 50%) — veteran with spouse: $877/month tax-free, $10,524/year. The VA Benefit Calculator applies real VA combined-ratings math and estimates monthly compensation by dependent status.
Enter up to three disability ratings and dependent status. The calculator serves the estimate.
This guide explains VA disability math, how to use the calculator, two worked examples, the tax-free advantage, practical tips, fifteen FAQs, and honest caveats.
VA Math: The Whole-Person Theory
The VA rates the whole person: each new rating applies to the remaining efficiency. 30% + 20%: the 20% applies to the remaining 70% → 14% → combined 44% → rounds to 40%. Formula: combine highest first, each rating × remaining ÷ 100. Three ratings compound the same way. Simple addition overstates — VA math is the law.
The Tax-Free Advantage
VA disability compensation is federal tax-free (most states too). $877/month spends like ~$1,100 of taxable income — a 25% purchasing-power bonus. $10,524/year tax-free ≈ $14,000 gross salary equivalent. This is why the monthly figure understates its value: compare against take-home pay, not gross.
How to Use the VA Benefit Calculator
Step 1: Enter Disability Rating 1 (your highest).
Step 2: Add Ratings 2 and 3 if applicable.
Step 3: Select Dependent Status.
Step 4: Click Calculate VA Benefit. Note the combined rating.
Worked Example 1: 30% + 20% — Veteran with Spouse
Ratings: 30% + 20%; dependents: spouse.
VA math: 30 + (70 × 20%) = 30 + 14 = 44 → 40% combined. Monthly: $781 base + $96 spouse = $877/month. Annual: $10,524 tax-free.
The rounding matters: 44% rounds to 40%, but 45% would round to 50% — a single percentage point of combined rating can swing hundreds monthly. This is why appealing a 10% to 20% on one condition can cascade: the combined math amplifies every individual increase.
Worked Example 2: 50% + 30% + 10% — Spouse + 2 Children
Ratings: 50% + 30% + 10%; dependents: spouse + 2 children.
VA math: 50 + (50 × 30%) = 65; 65 + (35 × 10%) = 68.5 → 70% combined. Monthly: $1,789 + $396 = $2,185/month. Annual: $26,220 tax-free.
Three ratings totaling “90%” by addition yield 70% by VA math — yet pay $2,185/month tax-free, ≈ $35,000 gross equivalent. Dependents add $396/month here — always keep dependency records current with the VA; unclaimed dependents are unclaimed money.
Beyond Monthly Compensation
Rating-gated benefits: 30%+: additional dependent allowances. 50%+: concurrent retirement/disability pay (CRDP). 100%: CHAMPVA for dependents, education benefits (Chapter 35), property tax exemptions (many states), commissary access. The monthly check is the headline; the ancillary benefits at higher ratings multiply the value.
Key Factors and Limits
Rates are illustrative estimates — verify current tables at va.gov (adjusted annually for COLA). Individual unemployability (TDIU) pays at 100% for qualifying veterans. This estimates compensation only, not pension or ancillary benefits. This is educational, not legal/veterans advice — consult an accredited VSO.
Tips for Veterans
- Claim every condition. Ratings compound via VA math — secondary conditions count too.
- Keep dependents updated. Marriage, births, divorces — report promptly; money follows records.
- Appeal low ratings. One condition’s increase cascades through combined math.
- Learn VA math. 30+20=40, not 50 — set expectations by the real formula.
- Document everything. Medical records win claims — continuity of treatment evidence.
- Use a VSO. Accredited Veterans Service Organizations file for free — never pay a claim shark.
- Know the ancillary benefits. 100% unlocks CHAMPVA, education, tax breaks — claim them all.
- Re-exams matter. Attend scheduled re-examinations — missed exams can reduce ratings.
Frequently Asked Questions
1. 30% + 20% = ?
40% combined — VA math applies each rating to remaining efficiency, then rounds to the nearest 10%.
2. Is VA disability taxable?
No — federal tax-free, and most states exempt it too. A major purchasing-power advantage.
3. How do dependents affect pay?
30%+ ratings add dependent allowances — e.g., +$96/month for a spouse at 40%.
4. What is TDIU?
Total Disability based on Individual Unemployability — pays at the 100% rate when service-connected conditions prevent work.
5. Can ratings increase?
Yes — file for increase when conditions worsen. Decreases are possible at re-exams too.
6. 100% benefits beyond pay?
CHAMPVA, Chapter 35 education, state property tax exemptions, commissary — the package multiplies.
7. How often are rates updated?
Annually with COLA — verify current tables at va.gov before planning.
8. What is a VSO?
Veterans Service Organization — accredited reps who file claims free. Never pay for claim help.
9. Secondary conditions?
Conditions caused by service-connected ones (e.g., depression from chronic pain) — claimable and compounding.
10. Combined 94%?
Rounds to 90% — but 95% rounds to 100%. The rounding cliff makes every point near thresholds precious.
11. Can I work with VA disability?
Yes (except TDIU has income limits) — ratings compensate the condition, not employment.
12. Back pay?
Effective dates can yield retroactive lump sums — another reason to file early and appeal.
13. What if my claim is denied?
Appeal — supplemental claims, higher-level review, or Board appeal. Denials are often reversed.
14. Do I need a lawyer?
Start with a free VSO — attorneys (accredited) help complex appeals, capped at 20% of back pay typically.
15. Biggest VA benefit mistake?
Not filing — millions in earned benefits go unclaimed yearly. File for every service-connected condition.
CONCLUSION
The VA Benefit Calculator applies the real math: 30% + 20% = 40% combined → $877/month tax-free for a veteran with spouse ($10,524/year). The three-rating 70% case: $2,185/month — $26,220 tax-free, ≈ $35,000 gross equivalent.
Claim every condition, keep dependents current, appeal the lows — VA math rewards the thorough. The benefits were earned; the calculator just prices them.
