Two numbers decide your check. One is your combined disability rating. The other is who lives in your house. Most veterans understand the first one roughly and the second one not at all, and the second one is where the surprises live, because dependents don’t work like a bonus added to the end of the calculation. They work like a switch that’s off until a certain point and a multiplier after it.
Start with the switch, since it’s the single most consequential line on the whole rate table.
Below 30%, the Rate Table Doesn’t Know Your Family Exists
At the current rates, effective December 1, 2025, a 10% rating pays $180.42 a month and a 20% rating pays $356.66. Married with four kids and a dependent parent, those numbers don’t move. Not by a dollar. Additional compensation for dependents requires a combined rating of at least 30%.
Now step over the line. At 30%, a veteran alone gets $552.47. The same veteran with a spouse and one child gets $666.47.
So run the two versions of a single 10-point increase. A single veteran going from 20% to 30% gains $195.81 a month. A married veteran with one child going from 20% to 30% gains $309.81, because that step did two things at once: it raised the base rate and it turned the dependent payments on. Over a year, that’s $3,717.72 for the same ten points that another veteran valued at $2,349.72.
This is why the 20 to 30 boundary is worth fighting over in a way that, say, 40 to 50 usually isn’t. It’s not a bigger step. It’s a different kind of step.
A reliable VA disability calculator can help you in a big way here (you can check a good VA calculator here). Just enter all variables and you will get an accurate figure.
Ratings Don’t Add Up, They Combine
Before any of that applies, you have to know how VA arrived at the combined number, because veterans consistently expect arithmetic and get something else.
VA uses what it calls the whole person theory. A 50% rating and a 30% rating don’t make 80%. The 50% is taken first, leaving half of you unaffected, and the 30% applies to what’s left: 15 points, for a total of 65, which rounds to 70%. Rounding runs to the nearest 10, with values ending in 1 through 4 going down and 5 through 9 going up. A veteran sitting at a combined 64 is paid at 60%. One point of raw value separates them from a 70% check.
The practical consequence catches people out constantly. Once you’re at 70%, a newly granted 10% condition adds roughly three points of raw value. Three points usually changes nothing at all. The claim was still correct to file, and it may matter later when something else gets added, but nobody should expect that grant letter to change the deposit.
Above 30%, the Same Spouse is Worth More the Higher You Go
Here’s the part that isn’t obvious from a quick glance at the table. The dependent amounts aren’t fixed. They scale with the rating, and steeply.
- At 30%, adding a spouse takes you from $552.47 to $617.47. That spouse is worth $65 a month.
- At 100%, adding a spouse takes you from $3,938.58 to $4,158.17. Same spouse, same marriage certificate, now worth $219.59 a month. That’s about 3.4 times the value of the identical dependent at 30%.
- Add a child to the spouse and the gap widens again: $114 of dependent money at 30%, $380.41 at 100%. Children in school between 18 and 23 are their own category, running from $105 at the bottom of the 30% to 60% band up to $352.45 at 100%, and they require a separate form and a reason to keep filing it.
The takeaway isn’t that you should chase a rating for the dependent money. It’s that any accurate estimate of what a rating increase is worth to you has to be calculated with your actual household in the row, not from the veteran-alone column that most comparison charts print.
The 90 to 100 Jump is Not Like the Others
Watch the base rates climb for a single veteran. 70% pays $1,808.45. 80% pays $2,102.15. 90% pays $2,362.30. Steady increments of roughly $250 to $300 per step.
Then 100% pays $3,938.58.
That’s $1,576.28 more than 90%, a 67% increase for the same ten points that bought $260 one rung earlier. Every rating step is nominally equal and the last one is worth six of the others. For a veteran with a spouse and a child, the 100% row reads $4,318.99 a month, which annualizes to $51,827.88, and it isn’t taxable income, so the gross salary you’d need to match it is higher still.
The Money People Lose is Almost Always Paperwork
Nobody loses a rating by accident. They lose dependent money by filing late.
VA will pay you back to the date of the marriage, birth, or adoption if you already held a 30% rating and you file within one year of the event. Miss that window and back pay is generally limited to the date the claim was received, or up to a year before it. A child born in March whose paperwork goes in 14 months later costs the family every month in between, at the dependent rate for their rating, permanently.
The forms are unglamorous and specific. VA Form 21-686c for a spouse or a child under 18. VA Form 21-674 for the 18 to 23 year old in school, resubmitted when the school year says so, because the payment stops when full-time status does. VA Form 21P-509 for a dependent parent, which still goes in by mail.
It runs the other direction too. A dependent who leaves the household and stays on your award doesn’t vanish quietly. VA eventually catches it and bills you for the difference, and that bill can cover years.
So do this once, properly: open the rate table, find the row that matches your actual household rather than the one you had when you first filed, and check it against your deposit. If those two numbers disagree, the gap is almost never your rating. It’s a dependent VA doesn’t know about, or one it still thinks is there.
