Va Rating Calculator

Most veterans do not have one disability. They have three, five, sometimes eight, and the question that matters is how those separate percentages merge into a single combined rating. The Va Rating Calculator above is built for exactly that situation: enter up to six condition ratings, and it applies the real VA combined-ratings formula, shows your exact percentage, rounds it the way the VA rounds it, looks up your 2025 monthly pay, and even tells you what additional rating you would need to reach the next level.

If you have ever added your ratings together and wondered why the VA's number came back lower, this page is for you. VA math is not intuitive, but it is completely mechanical, and once you see the machinery, you can predict your combined rating to the decimal, price an appeal, and understand which of your conditions is actually moving the needle.

Why Ratings Cannot Simply Be Added

The VA rates disabilities against the whole person theory: a healthy person is 100 percent efficient, and each disability reduces the efficiency that remains. A 50 percent disability leaves you 50 percent efficient. A second disability rated at 30 percent does not take 30 percent of the original 100; it takes 30 percent of the remaining 50, which is 15. Your total disability is 65 percent, which rounds to a 70 percent combined rating.

This single idea explains every surprise in the system. Ten small ratings barely move the total because each one nibbles at an ever-shrinking remainder. One large rating dominates everything. And no combination of sub-100 ratings can ever reach exactly 100 through math alone in the way simple addition suggests, which is why the rounding rule at the end matters so much.

The Combined Ratings Formula, Step by Step

The VA's official procedure, applied from the highest rating to the lowest, is:

1. Sort your ratings from highest to lowest. Order matters for the intermediate steps, though the final total is the same regardless.
2. Start with 100 percent efficiency. This is the "whole person" you begin with.
3. Apply the highest rating. Multiply your current efficiency by (100 minus the rating), divided by 100. A 50 percent rating turns 100 into 50.
4. Apply each remaining rating the same way. Each rating multiplies the current remaining efficiency by its own (100 minus rating) over 100.
5. Subtract the final efficiency from 100. The result is your combined exact percentage.
6. Round to the nearest 10 percent. Values ending in 5 and above round up; below 5 round down. This rounded number is your official combined rating.

The calculator performs all six steps instantly, including the descending sort, so you never have to do the arithmetic by hand.

How to Use the Va Rating Calculator

1. Enter each condition's rating. Use the six dropdowns for up to six service-connected conditions. Leave unused ones on "None". Enter the ratings the VA assigned, or the ratings you expect.
2. Press Calculate. The tool lists your conditions, your combined exact percentage, your rounded final rating, and your estimated 2025 monthly and annual pay.
3. Read the next-level hint. The calculator tells you the smallest additional rating that would push you to the next 10 percent step, which is invaluable when deciding whether to file a new claim or an increase.
4. Press Reset to model scenarios. Try raising one condition at a time to discover which increase buys you the most additional combined percentage.

Worked Example 1: Three Conditions at 50, 30, and 10 Percent

Consider a veteran rated 50 percent for PTSD, 30 percent for a lumbar strain, and 10 percent for tinnitus. Simple addition says 90 percent. VA math says otherwise.

Step 1: Sort highest to lowest. The order is 50, 30, 10.

Step 2: Apply the 50 percent rating. Efficiency goes from 100 to 100 x 50 / 100 = 50.

Step 3: Apply the 30 percent rating. Efficiency goes from 50 to 50 x 70 / 100 = 35.

Step 4: Apply the 10 percent rating. Efficiency goes from 35 to 35 x 90 / 100 = 31.5.

Step 5: Compute disability. 100 minus 31.5 = 68.5 percent exact.

Step 6: Round. 68.5 rounds to 70 percent.

Step 7: Look up pay. A 70 percent combined rating pays $1,716.28 per month in 2025, or $20,595.36 per year. The calculator shows all of this in one click, including the exact 68.50 percent figure the VA's own worksheet would produce.

Worked Example 2: Using the Next-Level Hint

Now take the same veteran at 68.5 percent exact, rounded to 70 percent. The next level is 80 percent. What would it take to get there?

Step 1: Note the remaining efficiency. After the three conditions, 31.5 percent efficiency remains.

Step 2: Test candidate additional ratings. A new 10 percent rating would add 10 percent of 31.5, which is 3.15, bringing the exact total to 71.65 percent, still rounding to 70. A 20 percent rating adds 6.3, reaching 74.8 percent, still 70. A 30 percent rating adds 9.45, reaching 77.95 percent, which rounds to 80.

Step 3: Read the hint. The calculator reports: to reach 80 percent, you would need an additional rating of at least 30 percent. That single sentence tells the veteran that filing a new 10 percent claim is not worth the effort for rating purposes, while pursuing a 30 percent increase on an existing condition could change everything.

The Rounding Rule and Why Decimals Matter

The VA rounds the combined exact percentage to the nearest 10, and the boundary behavior is precise: 64.5 percent rounds up to 70, while 64.4 rounds down to 60. Because of this, veterans sitting at 63 or 64 percent exact are tantalizingly close to the next pay step, and even a small new rating, or a small increase to an existing one, can tip them over. The calculator displays the exact percentage to two decimals precisely so you can see how close you are to a boundary.

This is also why the order of operations does not change the answer. Whether you apply the 50 first or the 10 first, the multiplications commute and the final efficiency is identical. The VA specifies highest-to-lowest purely as a bookkeeping convention. If you ever check the calculator's work by hand and apply ratings in a different order, you should get the same exact percentage.

Which Condition Should You Try to Increase?

Not all increases are equal. Because each rating applies to the remaining efficiency, raising your highest rating buys more combined percentage than raising a small one. Going from 50 to 70 percent on your largest condition, when nothing else is rated, moves your combined rating by roughly the full 20 points of exact percentage. Adding a new 10 percent condition when you are already at 80 percent combined adds barely 2 points of exact percentage. The most productive habit is to model each candidate increase in the calculator separately and compare the resulting combined ratings before deciding where to focus your evidence and effort.

There is one more rule that shapes strategy: the anti-pyramiding rule. The VA will not rate the same symptom under two different diagnoses. You cannot be rated separately for PTSD and depression for the same set of symptoms, for example. When you model scenarios, make sure each condition you enter represents a genuinely distinct disability, or the VA will combine them into a single rating before the math even starts.

A Note on the Bilateral Factor

Veterans with disabilities on both sides of the body, such as both knees or both shoulders, should know the VA adds a bilateral factor: after combining the bilateral ratings, the VA adds half of the combined bilateral value as an extra factor before combining with the rest. This calculator uses the standard combined-ratings formula without the bilateral factor, which covers the vast majority of cases and matches the VA worksheet most veterans encounter. If you have paired bilateral disabilities, your official combined rating may come out slightly higher than this tool shows.

Tips for Getting an Accurate Combined Rating

1. Enter ratings highest to lowest, or let the tool sort. The calculator sorts automatically, but entering them in order helps you verify the list.
2. Use assigned ratings, not hoped-for ones, for planning. Model hoped-for ratings as separate scenarios so you do not confuse the two.
3. Watch the exact percentage, not just the rounded rating. Two veterans at 70 percent can be at 65.1 and 74.4 exact, with very different distances to 80.
4. Model one increase at a time. Change a single condition's rating and recalculate to isolate its effect on the total.
5. Remember the bilateral factor exists. Paired disabilities on both sides of the body may rate slightly higher officially than this tool shows.
6. Do not double-count symptoms. The anti-pyramiding rule means overlapping symptoms get one rating, not two.
7. Price every appeal. Compare the monthly pay at your current rating and your target rating to know exactly what a successful appeal is worth.

Frequently Asked Questions

1. What does the Va Rating Calculator do?

It combines up to six disability ratings using the official VA formula, shows your exact and rounded combined rating, estimates your 2025 monthly pay, and tells you what additional rating would reach the next level.

2. Why is my combined rating lower than the sum of my ratings?

The VA applies each rating to your remaining efficiency rather than adding them. A 50 and a 30 combine to 65 percent exact, which rounds to 70, not 80.

3. Does the order I enter ratings change the result?

No. The multiplications commute, so any order gives the same exact percentage. The VA uses highest-to-lowest as a convention, and the calculator sorts automatically.

4. How does VA rounding work?

The combined exact percentage rounds to the nearest 10 percent. Values of 64.5 and above round up to 70; below that they round down to 60.

5. What does the next-level hint tell me?

It computes the smallest additional single rating, in 10 percent steps, that would push your combined exact percentage up to the next 10 percent rating level.

6. Can combined ratings reach 100 percent?

Yes, through rounding: any exact percentage of 95 or above rounds to 100. Extremely high combinations can also compute above 95 directly.

7. What is the bilateral factor?

An extra factor the VA adds when you have disabilities on both sides of the body. This calculator uses the standard formula, so bilateral cases may rate slightly higher officially.

8. What is pyramiding and why does it matter?

Pyramiding is rating the same symptom under two diagnoses. The VA prohibits it, so make sure each condition you enter is a genuinely distinct disability.

9. How many conditions can I combine?

The VA combines all of your service-connected conditions with no limit. This calculator accepts up to six, which covers the great majority of veterans.

10. Is the monthly pay shown exact?

It is the 2025 base rate for your rounded combined rating for a veteran without dependents. Dependent additions and SMC can change your actual deposit.

11. My exact percentage is 69.4. Am I at 70 percent?

Yes. The VA rounds 69.4 to 70 percent. You would need to reach 74.5 exact to round up to 80.

12. Should I file a new 10 percent claim if I am at 88 percent exact?

Probably not for rating purposes alone: at 88 exact you already round to 90, and a small addition changes little. Model it in the calculator first.

13. Does the calculator handle TDIU?

No. TDIU pays at the 100 percent rate based on unemployability rather than schedular math, so it sits outside the combined-ratings formula.

14. Why do small ratings barely move my total?

Each rating applies to the efficiency remaining after larger ones. When little efficiency remains, even a 20 or 30 percent rating adds only a few exact points.

15. Where can I verify my official combined rating?

In your VA decision letter, your VA.gov disability profile, or by calling the VA. The calculator estimates; the VA's determination is official.

CONCLUSION

The Va Rating Calculator replaces guesswork with the actual mechanics of the VA system: sort, multiply against remaining efficiency, subtract from 100, round, and look up pay. With up to six conditions supported and a next-level hint that quantifies exactly what an additional rating would buy, it turns rating strategy from a hunch into arithmetic.

The strategic lessons are worth restating. Increases to your largest rating move the total most. Small additions near the top of the scale barely register. The rounding boundary is where battles are won, so watch your exact percentage. And every appeal has a price tag you can compute in advance. Model your scenarios, gather evidence for the increase that actually matters, and let the math guide the effort.
