It's a popular marketing tactic for many law firms and legal websites to offer a personal injury calculator that is meant to tell car wreck victims how much money their case is worth. You put in a few details and get a number right away. But in reality, these calculators are inaccurate and incomplete. They can't accurately assess the impact of your injury, don't have access to all the facts that may influence the outcome of your case, and can't consider other variables, such as pain and suffering.
