Multiple VA Disability Ratings Calculator

Combine multiple ratings with optional bilateral logic today. See rounded results, clear charts, and exports. Compare examples before planning your next finance review session.

Calculator

Enter each service-connected rating. Mark paired upper or lower areas only when a bilateral factor may apply.

Nearest 10%, with 5 rounded upward

Formula used

The calculator uses the remaining-efficiency method. Ratings are sorted from highest to lowest. Each new rating applies only to the efficiency that remains after previous ratings.

Combined after step = Previous combined + (100 - Previous combined) × Next rating ÷ 100

Final rounded rating = Raw combined rating rounded to the nearest 10%

When the bilateral option qualifies, paired left and right upper or lower values are combined first. Then 10% of that paired group value is added. The adjusted group then joins the main combined-rating sequence.

How to use this calculator

  1. Enter every individual disability rating as a number from 0 to 100.
  2. Give each row a short condition name for clear reports.
  3. Select a paired area only for qualifying left or right limb conditions.
  4. Turn on the bilateral factor if paired left and right conditions should be considered.
  5. Choose table style for whole-percent steps, or decimal style for detail.
  6. Press calculate. The result appears above the form.
  7. Use CSV or PDF buttons to save the summary.

Planning with multiple VA ratings

Multiple VA disability ratings do not add like normal percentages. A veteran with 40%, 20%, and 10% does not simply reach 70%. The system treats each new rating as a loss of remaining efficiency. This keeps the total from passing 100%. It also explains why small ratings may change the final rounded result less than expected.

Why order matters in the display

The calculation starts with the largest rating. It then applies the next rating to the remaining healthy portion. Sorting from high to low makes the steps easier to audit. The final combined value is then rounded to the nearest ten. A raw value of 74% usually rounds to 70%. A raw value of 75% usually rounds to 80%.

Bilateral factor planning

The bilateral factor can matter when qualifying disabilities affect both sides of a paired area. Examples include both legs or both arms. The calculator combines those paired ratings first. It then adds ten percent of that paired group value. This adjusted value enters the main calculation with the other ratings.

Finance review use

This page supports finance planning, claim review, and personal record keeping. It can help compare a current rating mix with a possible future mix. The CSV export is useful for spreadsheets. The PDF export is helpful for discussions, notes, and document packets. The chart shows how each rating changes the combined value. It also shows where a new rating has the strongest effect.

Scenario testing

You can test several possible outcomes before a claim review. Add one possible condition at a time. Change the percentage and submit again. Compare the rounded result with the raw value. This helps you see whether a change crosses a rounding threshold. It also helps explain why two different rating sets may produce the same final percentage.

Better data gives better estimates

Use exact individual ratings. Avoid entering a rounded combined rating as if it were one condition. Add clear names, sides, and notes. Review every row before exporting. This reduces mistakes and makes the final report easier to understand. Always compare calculator results with official decision letters. Rules, evidence, and effective dates can affect real outcomes.

Frequently asked questions

1. Does this calculator add ratings directly?

No. It uses remaining efficiency. Each rating reduces the portion left after earlier ratings. This is why 50% and 30% combine to 65%, then usually round to 70%.

2. Why are ratings sorted from highest to lowest?

Sorting makes the steps easier to follow. The combined result follows the same remaining-efficiency idea. High ratings first also match common rating-table explanations.

3. What does the bilateral factor option do?

It combines qualifying left and right paired-area ratings first. Then it adds 10% of that paired group value before joining the main rating sequence.

4. Should I choose table style or decimal style?

Use table style for whole-percent steps. Use decimal style when you want more calculation detail. Both finish with nearest-ten rounding.

5. Can a result exceed 100%?

No. The calculator caps combined disability at 100%. Remaining efficiency cannot go below zero in the calculation model.

6. What rating values should I enter?

Enter each individual service-connected rating. Do not enter a final combined rating as one condition unless you are testing a special scenario.

7. Are exports available after calculation?

Yes. After submitting the form, buttons appear for CSV and PDF downloads. They include ratings, steps, and the rounded result.

8. Is this an official decision tool?

No. It is an educational calculator. Official outcomes depend on regulations, evidence, effective dates, and formal decision letters.
