How Accurate Are Personal Injury Settlement Calculators? nn Lately we've heard some of our clients ask us if personal injury settlement calculators give an accurate appraisal of the value of the claim. The short answer is no. Personal injury settlement calculators do not work. Insurance companies don't use calculators, we don't use calculators, and if your case goes to trial there isn't going to be a calculator in the jury. There are a lot of factors that go into determining the value of the claim. If you do use a personal injury settlement calculator online, don't trust it. n
