Maximize Your Benefits. Optimize Your Life.

March 23, 2026

Every veteran with more than one service-connected condition has had this moment.

You get your decision letter. You see the individual ratings. You add them up in your head. And then you see the combined rating and think: "That can't be right."

50% + 40% = 70%? 30% + 20% + 10% = 50%? How?

Welcome to VA math — where the numbers don't work the way you think they do, and the VA sure as shit doesn't go out of their way to explain it.

So I built something that helps.

The VA doesn't add your ratings together. They use something called "whole person theory". Each rating applies to your remaining healthy percentage, not the total. You joined at 100% and then go down from there.

Here's how it works in plain English:

Say you have two conditions: 50% and 40%.

| Result | 50 + 20 = 70%. Not 90%. | 70% |

That second rating doesn't apply to 100 — it applies to the 50% of you the VA still considers "healthy." Every additional rating shrinks the remaining pool. That's why it gets exponentially harder to reach 100%.

This isn't just trivia. Understanding VA math changes how you approach your claims:

The order doesn't matter, but the size does. Your highest rating has the biggest impact on your combined number. A veteran with 70% + 10% + 10% ends up at 76% (rounds to 80%). But 50% + 30% + 20% + 10% gets you to 73% (rounds to 70%). More conditions doesn't always mean a higher rating.

Rounding is everything. The VA rounds to the nearest 10%. That means 74% rounds DOWN to 70%, but 75% rounds UP to 80%. The difference between 70% and 80%? About $500/month. One more 10% condition could push you over the rounding threshold and put hundreds more in your pocket every month.

The bilateral factor is your friend. If both sides of a body part are affected (both knees, both shoulders, both ankles), the VA adds a 10% bonus to that bilateral group before combining it with everything else. A lot of veterans don't know this and don't claim both sides. Sciatica that affects both legs? Bilateral. Both knees blown out from rucking? Bilateral.

Secondary conditions are “free” ratings you're probably missing. If you have PTSD, there's a good chance you also deal with sleep apnea, migraines, or GERD and the VA recognizes those as secondary conditions (38 CFR § 3.310). That means you can file for them because of your already service-connected condition. You don't need a new nexus to service. Sleep apnea alone is worth 50% if you use a CPAP. That one secondary claim could be the difference between 70% and 90%.

Special Monthly Compensation is money most veterans don't know about. If you've lost use of a body part, need aid and attendance, or are housebound due to your disabilities, SMC adds compensation on top of your combined rating. SMC-K alone adds $139.87/month per qualifying condition and it stacks. Veterans with erectile dysfunction secondary to medication, loss of a reproductive organ, or loss of use of a hand or foot often qualify and never file for it.

This is the thing I'm most proud of.

Every single condition in the lookup has a C&P Exam Tips badge. Hover over it and you'll see exactly what the examiner is evaluating, what veterans commonly forget to mention, and what to document before your exam. Unfortunately, you need to have the attitude that the examiner is not your friend. If they ask you “how are you today?” Don’t say “great” because that will be noted. Say something like “same old same old” or just grunt or if you really wanna be extra say “I’m here, aren’t I?”

For PTSD: Describe your worst days, not your average days. Document loss of jobs, broken relationships, social isolation.

For sleep apnea: If you use a CPAP, bring a photo of it and your prescription.

For back conditions: Do NOT push through the pain during range of motion testing — the examiner needs to see your actual limitation.

This is the stuff that separates a 30% rating from a 70% rating. Not because you're exaggerating — because you're finally describing your condition accurately instead of downplaying it out of military bravado.

This is not the place to play the “other guys probably had it worse” game, or remembering that time your SNCO called you soft for falling out of a ruck because you felt your ACL pop. These people hold your rating in their hands and a lot of them - for whatever reason - will act like the money is coming out of their pockets. So study for it and treat it as the most serious interview of your life.

Here's everything the tool includes:

The Combined Rating Calculator doesn't exist in a vacuum — it's one piece of a full toolkit I'm building to help you understand and maximize your benefits.

Already rated 100% P&T? Use the P&T Benefits Calculator to see the full lifetime value of your benefits — CHAMPVA, Chapter 35, property tax exemptions, commissary access, and more. Most 100% P&T veterans are leaving tens of thousands of dollars on the table because they don't know what they've earned.

Thinking about buying a home? The VA Loan Calculator shows you how the VA loan stacks up against FHA and conventional mortgages side by side. No down payment, no PMI, and if you're 10%+ rated, the VA funding fee is reduced or waived entirely. That's thousands of dollars saved at closing.

Transitioning out or already out? The Military to Civilian Salary Translator calculates your total compensation — base pay, BAH, BAS, tax advantages, TSP match, healthcare — and shows you what civilian salary you'd need to match it. Spoiler: it's higher than you think.

Using the GI Bill for business school? The MBA Comparison Tool lets you compare programs with GI Bill and Yellow Ribbon coverage factored in. See your true out-of-pocket cost and ROI across schools.

Start with the calculator. Figure out your combined rating. Then use the rest of the toolkit to make sure you're getting everything that rating entitles you to.

I built this because I got tired of watching veterans get confused by their own ratings and then get funneled into paying someone to explain public information to them. I won’t name names, but it rhymes with schmill and boppin.

The rating criteria are federal regulations. They're public and can be found here. Every veteran has the right to understand exactly how their rating was calculated and what they need to get the rating they deserve.

If this tool helps you — share it with someone who needs it. Forward this email. Text the link to your veteran group chat.

And if you find a condition that's missing from the lookup, hit reply and tell me. I'll add it.

Talk soon,
