VA Disability Compensation: How the Money Works
VA disability compensation is a monthly, tax-free payment read off a published rate table using two facts: your combined rating and your dependents. This pillar explains how percentages are assigned, how they combine under 38 CFR 4.25 with the bilateral factor and final rounding, and how effective dates produce retroactive pay.
VA disability compensation is a monthly payment to veterans with service-connected conditions, and it is not taxable income at the federal or state level. The amount is neither negotiated nor means-tested: it is read off a published rate table using exactly two facts — your combined disability rating and your dependent situation. Everything genuinely difficult about the money side comes from how that combined rating is produced and from which date the payments are treated as starting.
The combination arithmetic is where most of the confusion lives. Ratings do not add. They combine against remaining capacity in a defined order set out in 38 CFR 4.25, with an extra step for paired limbs in 38 CFR 4.26, and a final rounding to the nearest ten that decides which row of the rate table applies. Two veterans holding an identical list of percentages can land on different rows depending on whether the bilateral factor applies to any of them, which is why the published arithmetic is worth seeing in full rather than approximating.
This page explains those published rules and the arithmetic behind them, and links to the calculator that performs each step. It is education, not representation: this site does not prepare, file, review, or argue claims and charges nothing for anything connected to one. VA assigns ratings, sets effective dates, and pays benefits, and VA.gov is the source of record for every figure referenced here.
What the compensation actually is
VA disability compensation is a monthly, tax-free payment to veterans whose disabilities are connected to their military service. It is paid not for the injury itself but for the average impairment of earning capacity that the rating schedule assigns to a condition at a given severity, which is why two people with the same diagnosis can hold different percentages. Because it is compensation rather than assistance, household income and assets play no part in the amount. Other programs nevertheless treat the money differently from one another: it is excluded from federal taxable income, counted as unearned income in the SNAP calculation, and treated as qualifying income by many lenders. Each program sets its own rule, so the same payment can be invisible on a tax return and fully visible on a benefits application — a difference worth knowing before filling out either. The rate tables themselves are public, which means the amount attached to any rating and household combination can be looked up rather than guessed at.
How a condition receives a percentage
Every rated condition draws its percentage from the VA Schedule for Rating Disabilities in 38 CFR Part 4, which sets out criteria and levels for each diagnostic code. Raters apply those criteria to the evidence in the file, including examination findings, and record a percentage in steps of ten. Where a Compensation and Pension examination is ordered, the examiner documents findings for the rating specialist rather than deciding anything: the examiner records, the rater rates. Percentages are not permanent by default — reductions follow the reexamination rules, and ratings held for long periods carry protections that VA.gov describes in detail. Nothing computed on this site affects any part of that process; the calculators here reproduce published arithmetic so that a decision letter can be read with understanding. The schedule itself is amended from time to time through rulemaking, and amendments carry their own effective-date rules, so the criteria applied to a condition depend in part on when the decision was issued.
Combined ratings: the arithmetic in 38 CFR 4.25
Ratings combine rather than add, and the order of the operation matters. Begin with the highest percentage and treat it as the share of the body already impaired; the next rating then applies only to the capacity that remains. A 50% rating leaves 50% of capacity intact, so a second 50% rating takes half of that remainder and the running value becomes 75%. Continue in descending order, each successive rating acting only on the capacity still left, until every percentage has been folded in. This is why long lists of small ratings accumulate slowly near the top of the scale — the remaining capacity that each new rating can act on keeps shrinking, and no combination of ratings under 100% ever reaches 100% by arithmetic alone. The regulation also publishes a combined ratings table as a lookup grid, so the same result can be read off the table instead of computed by hand; the table and the arithmetic agree by construction.
The bilateral factor
When disabilities affect both arms, both legs, or paired skeletal muscles, 38 CFR 4.26 inserts an extra step into the combination. Those paired ratings are combined with each other first, and ten percent of that combined value is added to it before the result is merged with any other ratings. The rule recognises that impairment on both sides of the body compounds in a way that two unrelated conditions do not — losing function in one knee is a different problem from losing function in both. Because the bilateral factor is applied before the final rounding, it can move a veteran to a different row of the rate table entirely. The combined-rating calculator on this site applies it automatically when left and right limbs are tagged, and shows the added value as its own line so the effect is visible.
Rounding to the nearest ten
The value that emerges from the combination arithmetic is almost never a multiple of ten, and only multiples of ten appear on the rate tables. The final step rounds to the nearest ten: an exact combined value of 24 becomes 20, while 25 becomes 30. That single step explains why a small change in one condition sometimes moves the monthly payment and sometimes does not — it depends entirely on which side of the midpoint the unrounded value falls. Intermediate values are never rounded during the combination itself; rounding happens once, at the very end. Seeing the unrounded number is often the clearest explanation of a decision letter that looked wrong on first reading. Because rounding acts on that exact value, the informative question about a decision is frequently not what the rating is but what the unrounded value was, which is precisely what a combined-rating calculator exposes.
Dependents and the rate table
At combined ratings of 30% and above, the monthly amount depends on your household as well as your rating. The published tables carry separate rows for a veteran alone, with a spouse, with children, with dependent parents, and for combinations of those, plus added amounts for each additional child, for school-age children between 18 and 23, and for a spouse receiving Aid and Attendance. At 10% and 20% the rate is flat, and dependents do not change it at all. Because dependency is a fact VA holds on file rather than something recomputed each month, a dependent who was never added is a common — and correctable — reason a payment looks lower than the chart suggests. The pay estimator and the pay chart on this site read the same published rows, so the figure you see is the figure VA published. Ratings of 100% and awards of special monthly compensation sit on their own rows and additional schedules, which is why the highest-paying combinations are not always the ones a quick chart lookup suggests.
Effective dates decide the money
An effective date is generally the later of the date entitlement arose and the date VA received the claim, and payment begins the first day of the month after that date under 38 U.S.C. 5111. A claim received within one year of discharge can carry an effective date of the day after separation. Submitting an intent to file preserves that date for up to a year while the full claim is completed, and in practice it is often the single largest determinant of a retroactive amount. Increases, reopened claims, and awards under newly liberalising regulations each have their own effective-date rules, described on VA.gov. Only VA assigns the date; the calculators here take the date from your decision and compute forward from it rather than predicting what it will be.
How back pay is computed
Retroactive pay covers the months between the effective date and the decision, with each month paid at the rate in force for your rating and dependent status during that month. Rate tables change every December 1, so a retroactive period that spans a rate-year boundary is paid partly at the old table and partly at the new one — a detail that a single-rate estimate misses. VA states that most retroactive payments arrive within about fifteen days of the decision, as a deposit separate from the first regular monthly payment. Fee-based representation is regulated rather than open: fees are permitted only at defined stages, only for VA-accredited attorneys and agents, and recognised Veterans Service Organizations assist without charging for it. The back-pay calculator on this site applies the correct table to each month and itemises the total by rate year. The decision date and the date a payment is actually released are not the same thing, and both appear on the paperwork, which is worth checking before reconciling a deposit against any estimate.
The annual cost-of-living adjustment
VA compensation rates are adjusted by the same cost-of-living percentage that the Social Security Administration announces each October from third-quarter CPI-W data. The adjusted VA rates take effect on December 1, a month before the Social Security increase reaches January payments, which is why the two systems appear briefly out of step each winter. Because the adjustment is a percentage applied to every row of the table, higher ratings and larger households see larger absolute increases from the same announcement. The rate year therefore runs from December through November, and that December 1 boundary is the line every back-pay computation has to respect. This site publishes each new table once VA posts it, with the verification date attached and the prior year kept online for comparison. Keeping the prior year available is what makes the change checkable: setting two adjacent rate years side by side shows exactly what the adjustment added at each rating and household combination.
What this site is, and who decides
This is a set of calculators and explainers built on published regulations and published rate tables, and nothing more. This site does not prepare, file, review, or argue claims, accepts no fee for anything connected to a claim, and has no relationship with VA of any kind. Under 38 CFR 14.636, only VA-accredited attorneys, accredited claims agents, and recognised Veterans Service Organization representatives may assist with claims, and VA publishes a searchable accreditation directory for checking anyone who offers. Every rating, every effective date, and every payment is determined by VA in a rating decision, and no figure on this site changes any of them. The official VA links below cover rates, ratings, effective dates, the claim-exam process, and accreditation.

Frequently asked questions
Ratings combine against remaining capacity instead of adding. A 50% rating leaves 50% of capacity, so a second 50% rating takes half of what remains, producing an exact combined value of 75%, which rounds to 80% under 38 CFR 4.25. No combination of ratings below 100% reaches 100% by arithmetic alone.
