Did You Know?
The VA rounds your combined disability to the nearest 10. A combined 74% rounds to 70%, but 75% rounds to 80% — a difference of hundreds of dollars per month.
If you've ever looked at your disability ratings and wondered why they don't add up to what you expected, you're not alone. Most veterans assume their ratings stack like numbers on a scoreboard. They don't — and understanding why could change how you approach every future claim.
The Myth: Your Ratings Just Add Up
It seems obvious: 50% plus 30% equals 80%, right? VA's combined-ratings table works differently. Understanding the calculation can help you check a decision and estimate compensation, but a calculator does not determine whether a condition should be claimed or service connected.
How 'Whole Person' Math Actually Works
The VA starts by thinking of you as a 100% whole person. Your highest rating takes a percentage of that whole person first. Each additional rating then takes a percentage of what's left — not of the original 100%. Here's an example: You have a 70% rating and a 30% rating. The 70% takes 70 points from your 100, leaving 30. The 30% rating then takes 30% of that remaining 30 — which is 9. Your combined disability is 79%, which rounds to 80%. Not 100%. The VA calls this the 'whole person method,' and it surprises almost everyone the first time they see it.
Why This Matters for You
Additional service-connected ratings can change the combined result, but VA math makes the effect non-linear. Use VA's current compensation table and your actual combined ratings when estimating a possible payment change.
Program Thresholds to Verify
- 30% — Eligible dependents may add compensation after VA adds them to the award
- 50% — May affect VA healthcare priority and copays under current enrollment rules
- TDIU — Common schedular thresholds include one 60% disability or a 70% combined rating with one disability at 40%, but other rules can apply
- 100% — Highest schedular compensation rate; dental and other programs have separate criteria
- 100% P&T — VA considers the total disability not expected to improve; family and state programs still have their own eligibility rules
Estimate the Combined Result
Use the VA Wayfinder calculator to estimate how existing or hypothetical ratings combine, then compare the rounded result with VA's current compensation table. The estimate is educational only: claim and decision choices should be based on the facts, evidence, and applicable rules—not on a projected payment.
