2026 rates (effective December 1, 2025) — 2.8% COLA applied
VA disability compensation is a monthly, tax-free benefit paid to veterans who have a service-connected disability — a physical or mental condition that was caused or made worse by military service. Understanding how to calculate your combined VA disability rating and the resulting monthly compensation can be confusing because the VA does not simply add your disability percentages together. Instead, it uses a method known as 'VA math' or the whole-person theory, where each additional rating applies only to the portion of you that is not yet rated as disabled. This calculator implements the official VA Combined Ratings Formula as described in 38 CFR Part 4 and uses the 2026 VA compensation rate tables that took effect on December 1, 2025, reflecting the 2.8% cost-of-living adjustment (COLA) authorized under the Veterans' Compensation Cost-of-Living Adjustment Act. Whether you have a single disability or a complex combination of service-connected conditions, this tool gives you an accurate estimate of your potential monthly benefit before you ever contact the VA or a Veterans Service Organization. Who needs this calculator? Any veteran who has filed, or is considering filing, a VA disability claim will benefit from understanding their combined rating and corresponding compensation tier. Active-duty service members transitioning out of the military, veterans who want to see how adding a new condition to an existing claim might affect their pay, and dependents trying to understand a loved one's VA benefits are all common users. The tool also helps you compare your current 2025 rate with the new 2026 rate to quantify exactly how much more you will receive after the COLA adjustment. The calculation process starts by entering each service-connected disability, its rating (10% through 100% in steps of 10), and whether it affects a specific extremity (left arm, right arm, left leg, right leg, or other). The calculator then sorts disabilities from highest to lowest rating and applies the VA math formula iteratively. If you have disabilities on both sides of a paired extremity — for example, both a left knee and a right knee condition — the bilateral factor automatically applies, adding a 10% bonus to the bilateral group's combined rating before folding it into the overall total. This bilateral factor, governed by 38 CFR § 4.26, rewards veterans for paired-extremity conditions that collectively impair a larger portion of functional ability than unpaired conditions would. Once the raw combined percentage is calculated, it is rounded to the nearest 10% per VA rounding rules — values of 1–4 round down and values of 5–9 round up. This rounded percentage determines your compensation tier. Monthly amounts for 2026 range from $180.42 at 10% to $3,938.58 at 100%. Veterans rated at 30% or higher receive additional monthly amounts for eligible dependents including a spouse, a spouse who requires Aid and Attendance, children under 18, children between 18 and 24 enrolled in qualifying school programs, and dependent parents. Dependent additions do not apply to 10% and 20% ratings. The calculator also evaluates Total Disability based on Individual Unemployability (TDIU) eligibility under the schedular criteria of 38 CFR 4.16(a): you may qualify if a single disability is rated at 60% or higher, or if at least one disability is rated 40% or higher and your combined rating reaches 70% or higher. TDIU allows veterans to receive compensation at the 100% rate even if their combined rating is below 100%, provided their service-connected conditions prevent substantially gainful employment. The Special Monthly Compensation-K (SMC-K) option covers anatomical or functional loss of a hand, foot, arm, leg, or reproductive organs, adding approximately $131.60 per award per month. All estimates are based on publicly available 2026 VA rate tables and standard VA calculation methods. They are provided for educational and planning purposes only and are not an official VA disability determination. Actual benefits depend on your complete service record, medical evidence, VA adjudication decisions, and individual circumstances. Always consult a VA-accredited Veterans Service Organization representative or VA-accredited attorney for guidance on your specific claim.
Understanding VA Disability Compensation
What Is VA Disability Compensation?
VA disability compensation is a monthly, tax-free monetary benefit paid to veterans whose illness or injury was incurred or aggravated during active military service. The amount depends on your combined disability rating — a single percentage that the VA calculates from all of your individual service-connected conditions. Ratings are expressed in multiples of 10 from 10% to 100%. A 0% rating acknowledges a service connection but pays no monthly compensation. The combined rating is not simply the sum of individual ratings; it is calculated using the VA's whole-person method, which means combining a 50% and a 30% disability yields 65% (not 80%), which rounds to 70%. Compensation is completely exempt from federal and state income taxes, making it particularly valuable for veterans who are unable to work due to their service-connected conditions.
How Is VA Compensation Calculated?
The VA uses the 'whole-person theory' to combine multiple disability ratings. The process works as follows: sort all ratings from highest to lowest; apply the highest rating first (e.g., a 50% disability means you are now 50% disabled and 50% remains); apply the next rating to the remaining healthy percentage (30% of the remaining 50% = 15%, so combined = 65%); continue until all disabilities are applied; and finally round to the nearest 10%. The bilateral factor adds a 10% bonus when you have service-connected disabilities on both sides of a paired extremity set (both arms or both legs). Monthly compensation amounts are then looked up from the official VA rate table for your rounded combined rating, with additional amounts for eligible dependents at the 30%+ tier. The 2026 tables reflect a 2.8% cost-of-living adjustment effective December 1, 2025.
Why Does Your VA Rating Matter?
Your VA combined rating determines far more than just monthly compensation. At 30%+ you gain dependent additions that can meaningfully increase monthly pay. At 50%+ you become eligible for VA dental care. At 70%+ you qualify for a VA fee waiver for VA health care. At 100% (or via TDIU) you and your dependents may qualify for CHAMPVA healthcare coverage, Dependents' Educational Assistance (DEA), significant state property tax exemptions, commissary and exchange access, the America the Beautiful free lifetime national parks pass, and additional VA dental benefits. Veterans rated 100% Permanent and Total (P&T) receive the highest level of stability in their benefits, as their rating cannot be reduced. Understanding your current rating and the impact of adding new conditions is essential for financial planning and maximizing the benefits you have earned through your service.
Limitations of This Calculator
This calculator provides estimates based on standard VA formulas and publicly available 2026 rate tables. It cannot account for every variable in an actual VA adjudication. Factors not modeled include: the specific diagnostic codes and rating criteria the VA applies to your conditions; secondary conditions, temporary 100% ratings during hospitalization, or ratings based on individual unemployability granted under extraschedular criteria; state-specific property tax exemptions and other state-level benefits that vary widely; Special Monthly Compensation levels above SMC-K (SMC-L, M, N, O, P, Q, R, S) which require official VA adjudication; protected ratings, individual circumstances, and any retroactive effective dates for pending claims. Always consult a VA-accredited Veterans Service Organization (VSO), VA-accredited claims agent, or VA-accredited attorney for official claims assistance and legal advice specific to your situation.

Example 1: Three Conditions — 50%, 30%, 20%
Apply 50%: combined = 0 + (100 × 0.50) = 50
Apply 30%: combined = 50 + (50 × 0.30) = 65
Apply 20%: combined = 65 + (35 × 0.20) = 72

How to Use This VA Disability Calculator
Add Your Service-Connected Disabilities
Enter each service-connected disability by clicking 'Add Disability' or selecting a common condition preset. For each disability, enter a name (optional but helpful), select its VA rating (10%–100% in steps of 10), and choose the body area — Left Arm, Right Arm, Left Leg, Right Leg, or Non-extremity/Other. The calculator automatically detects bilateral pairs and applies the 10% bilateral factor (38 CFR § 4.26) when you have conditions on both sides of a paired extremity.
Enter Dependent Information
Select your marital status and indicate whether your spouse requires Aid & Attendance assistance. Enter the number of dependent children under 18, children aged 18–24 enrolled in a qualifying school program, and dependent parents (0, 1, or 2). Dependent additions only apply if your combined rating is 30% or higher — the calculator automatically handles this rule and will notify you if your rating is below the threshold.

Frequently Asked Questions
Why doesn't the VA just add my disability percentages together?
The VA uses the 'whole-person theory,' which holds that percentages must be applied to successively smaller portions of your remaining 'whole person.' After a 50% disability, you still have 50% remaining — not 0%. A 30% disability then applies to that remaining 50%, adding 15 percentage points for a combined total of 65%, not 80%. This method prevents a logical impossibility (ratings adding past 100%) and reflects the concept that your remaining functional capacity decreases with each additional condition. It is why a veteran with four conditions rated 40% each ends up with a combined rating of roughly 87% rather than 160%. The VA rounds this final number to the nearest 10% to determine your compensation tier.
What is the bilateral factor and when does it apply?
The bilateral factor is a 10% bonus added under 38 CFR § 4.26 when a veteran has service-connected disabilities affecting both sides of a paired set of extremities — both arms, both legs, or paired skeletal muscle groups. The VA first combines the bilateral pair using standard VA math, then multiplies the result by 1.10 before including it in the overall combined rating calculation. For example, a right knee rated 30% and a left knee rated 20% combine to 44%, and with the bilateral factor become 48.4%. The VA applies the bilateral factor only when it benefits the veteran. This calculator automatically detects bilateral pairs based on the extremity type you select for each disability and applies the factor accordingly.
What is TDIU and how do I know if I qualify?
Total Disability based on Individual Unemployability (TDIU) allows veterans to receive compensation at the 100% rate even if their combined VA rating is below 100%, provided their service-connected disabilities prevent them from maintaining substantially gainful employment (income above roughly $15,060/year for a single person). Under schedular TDIU (38 CFR 4.16(a)), you may qualify if a single disability is rated 60% or higher, or if at least one disability is 40% or higher and your combined rating is 70% or higher. Extraschedular TDIU under 4.16(b) can apply when you do not meet schedular thresholds but still cannot work due to your service-connected conditions — this requires referral to VA Central Office. This calculator automatically checks the schedular criteria and displays an alert if you appear to qualify.
Do dependents increase my VA disability rating?
No. Dependents do not change your combined disability rating percentage. They only increase the monthly dollar amount of your compensation. Dependent additions are available only when your combined rating is 30% or higher. At 10% or 20%, you receive only the base rate regardless of family size. At 30%+, you can receive additional monthly amounts for a spouse (plus extra if the spouse requires Aid & Attendance), dependent children under 18, dependent children aged 18–24 enrolled in a qualifying school or training program, and dependent parents. The 2026 additions range from $32 per child under 18 at the 30% tier to $352.45 per school-age child at the 100% tier.
What is SMC-K and how much does it add?
Special Monthly Compensation-K (SMC-K) is an additional monthly benefit paid on top of your regular VA compensation for certain severe conditions. It applies to the anatomical loss or loss of use of one hand, foot, leg, or arm; loss of one eye; and loss of reproductive organs. It is additive to your base rate and is not affected by your combined disability percentage. For 2026, SMC-K is approximately $131.60 per month per qualifying condition, and veterans can receive up to three SMC-K awards simultaneously (for example, loss of use of both hands and one eye). SMC levels above K — such as Aid and Attendance (SMC-L), Housebound (SMC-M), and higher levels — require full VA adjudication and are not calculated by this tool.
What additional benefits come with a 100% VA rating?
A 100% combined rating (or 100% by TDIU) unlocks a significant set of additional federal benefits beyond the base monthly compensation of $3,938.58. These include CHAMPVA, which provides healthcare coverage for eligible dependents; Dependents' Educational Assistance (DEA), which provides education benefits to eligible dependents; VA dental care for the 100% veteran; enhanced Vocational Rehabilitation and Employment (VR&E) services; commissary and exchange access at military installations; and the America the Beautiful free lifetime national parks pass. Many states also offer substantial property tax exemptions, vehicle registration fee waivers, and other state-level benefits for 100% P&T veterans, though these vary by state and are not included in this calculator's estimates.
