38 CFR 4.25 Table I, checked against all 684 cells, and the bilateral factor of 38 CFR 4.26 when both arms or both legs are rated. VA's rating decision is final. How this is calculated.

VA does not add disability ratings: it combines them on the efficiency each one leaves, using Table I of 38 CFR 4.25. A 50% rating leaves 50% efficiency; a further 30% takes 30% of what is left, so the person is 65% disabled, and VA rounds that combined value once, at the end, to the nearest multiple of ten, with 5 going up: 65 becomes 70%. With three or more ratings, each new one is combined with the value reached so far, from the most to the least severe. That is why six ratings of 10% give 47 and a 50% rating, and why ten of them give only 65. The calculator below applies the table and the bilateral factor of 38 CFR 4.26 to your list; the full table follows, generated by the same formula and checked against all 684 printed cells. Your rating decides the monthly amount, $1,808.45 at 70% for a veteran alone in 2026.

Table I, combined ratings (38 CFR 4.25)

Left column: the combined value reached so far (or your highest rating). Top row: the next rating. The cell is the new combined value. The table below is generated by the formula value + rating × (100 − value) ÷ 100, rounded to a whole number with halves going up, and matches every cell of the table published in the Code of Federal Regulations.

Three examples, step by step

60%, 40% and 20%. Row 60, column 40: 76. Row 76, column 20: 81. Final rating 80%. This is the example printed in the regulation.

70%, 30% and 10%. Row 70, column 30: 79. Row 79, column 10: 81. Final rating 80%.

40%, 20%, 20% and 10%. 40 with 20 gives 52; with the second 20, 62; with 10, 66. Final rating 70%.

Why the table exists

The rating schedule measures loss of earning capacity, and a person cannot lose more than all of it. Adding ratings would quickly pass 100% for veterans with many conditions. Combining them keeps the total under 100 and reflects the idea that a second disability affects a person who is already partly disabled. The cost is that the gains shrink as the rating climbs: a 20% rating adds 10 points to a veteran at 50, but only 4 to a veteran at 80. Before filing a new claim, it is worth testing what the new rating would change; the VA disability calculator does it with the family and retired pay, and the 2026 rate chart gives the amount at each rating.

Checking a decision against the table

A rating decision lists each condition with its diagnostic code and percentage, then the combined rating. To check it, write down every compensable rating, set aside the ones on the arms and legs to see whether the bilateral factor applies, and combine in order. Three errors come up again and again: a rating dropped from the combination after a later decision, a bilateral factor that should have been applied to both knees or both feet, and a combination done in the wrong order, which can change the result by one point at the rounding line. If your result is higher than VA's, a higher-level review asks a senior reviewer to look at the same file without new evidence; it must be requested within one year of the decision.

Remember that the table only decides the percentage. The amount paid also depends on the family once the combined rating reaches 30%, and for a military retiree on how the rating interacts with retired pay, which the CRDP calculator shows.

Questions veterans and service members ask

How do I use the VA combined ratings table by hand?

Sort your ratings from highest to lowest. Find the highest in the left column and the next one in the top row: the cell gives the combined value. Use that value as the new row and combine it with your third rating, and so on. Round only the last value to the nearest 10, with 5 going up. The calculator on this page does the same and shows each value.

Why does VA math give 70% for 50% and 30%?

Because 30% applies to the 50% of efficiency left by the first rating: 30% of 50 is 15, so the combined value is 65. VA converts the final value to the nearest number divisible by ten, and values ending in 5 go up, so 65 becomes 70%. With 40% and 20% the value is 52 and the rating 50%.

Does VA round after every rating it combines?

No. 38 CFR 4.25(b) says the conversion to the nearest degree divisible by 10 is done once per decision, after all disabilities are combined. Each intermediate value is used exactly as found in the table. Rounding at every step would overstate some ratings and understate others; our calculator follows the regulation and rounds once.

What is the highest combined value that still rounds down?

Any value ending in 1 to 4 rounds down: 94 gives 90%, 84 gives 80%. A value of 95 gives 100%, which is why veterans at a combined 94 are one small rating away from the full rate. The highest value in Table I is 99, reached for example by combining 90 with 90.

Do 0% ratings count in the combined rating?

No. A 0% rating is service connected but not compensable, so it adds nothing to the combination. It still matters: the condition can be increased later without proving service connection again, and two or more permanent 0% ratings that interfere with employability can justify a 10% rating under 38 CFR 3.324 when there is no other compensable rating.

How is the bilateral factor added in VA math?

Before any other step: the ratings of both arms or both legs are combined, 10% of the result is added, and the total counts as one rating in the order of severity. Two knees at 10% become 21. Mark the body part of each rating in the calculator to apply it.
