As a Cincinnati Ohio personal injury lawyer I have to calculate a fair value for the harm caused to my clients almost daily. In order to do that I need to know that law on damages. I also must walk in my client's shoes. Even though the law on damages is the same the many factors that go into the mix of a particular case is different.
Personal injury pain and suffering calculator even by the best personal injury lawyer is both science and art. By science I mean the experience of a good personal injury lawyer that has many settlements to their credit, has researched many settlements, and gone to trial on many cases.
There is no such thing as a settlement injury formula. Many lay people think there is a settlement injury formula for their personal injury claim. This is fostered by so called self help books that tell you not to hire an attorney. I recently downloaded one of those "Settle my own Car Accident Case Books" and it gave a formula of 2,3,4 times your medical bills plus your lost wages.
