Any figures I give you are for illustrative purposes only. So don't even think of them in connection with your claim because your settlement could be between a dollar and a gazillion dollars.
Let's talk about the disability first. Theoretically, the way you figure compensation for a permanent disability (using your percentage and income) is like this.
12% of 35,000 = $4200. Adjust that for inflation over the next 32 years till normal retirement age of 65.
The gummint explains to me that my social security hasn't gotten a cost of living increase in 09 and 10 because there's been no inflation.
However, let's figure 2% average inflation per year just for illustration purposes.
$4200 per year for 32 years at 2% is going to amount to about $197,000.
But that's not what you'd get. You'd get the present value of that amount which is the amount when invested at a reasonable rate of return would get you to $197,000 after 32 years. Using a 5% rate of return (again, being generous) it would take about $41,000.
"But what about raises?" you say. Good point. Let's figure 5% merit raise per year (more generosity), add that 5% to the 2% inflation and the $4200 becomes about $532,000. Present value of that at a 5% rate of return is about $110,000.
So let's say that, for the permanent disability alone, you might get between $41,000 and $110,000.
To that you add your meds to date (about $30,000), the 3 months portion of your earnings (about $5250), future meds (anybody's guess), and pain and suffering (also anybody's guess - there's no formula).
Your lawyer may have other ways of calculating the demand. And I'm not saying that a lifetime of pain isn't worth half a million, it's just that the reality of liability claims is a great big monkey wrench in the works.
I would be surprised if the insurance company's first offer even reached $100,000. Your lawyer might be able to negotiate for a while but eventually he'd have to file the lawsuit. That's when the insurance company has to factor in the cost of litigation in relation to the cost of settlement and the offers tend to get a little better.
Not a lot, though. The disadvantages of your claim is that you still have the same job and the same income and the disability requires you to take a few extra breaks during the day. At some time down the line, if you go to court, you'll be in front of a jury that see's a healthy looking young person with no visible disability and the same employment as before the accident. They will pretty much zone out through all the medical mumbo jumbo and wonder why a healthy looking young person wants lots of money. The result is likely to be very disappointing and your lawyer will get 40% of the award instead of the 30% that he would have gotten for a settlement.
Sure, I could tell you to ask for half a million. I could tell you that you are entitled to half a million. And others might tell you that. But what good would that do you? Would you rather be prepared for the reality or have it surprise you when you aren't prepared for it?
As for the PTSD, there's not going to be any money in that. I'm sure that you really are "nervous now about driving, panic attacks and all that" but paying a psychiatrist is not the cure. In fact, the whole point about being a psychiatrist is that you don't make a living curing people, you make a living treating people (like chiropractors).
I'll leave you with Adjusterjack's fast cure for PAASD (Post Auto Accident Stress Disorder). Go rent yourself a high performance Mustang, Camaro, Challenger, or even a Corvette for a week. Take it out everyday. Drive the highways and the back roads for hours at a time. By the end of the week you won't want to give the car back.
