Every car accident is different and there can be thousands of variables to consider when calculating a settlement amount. These include your injuries, medical bills, loss of income, treatment plans, and other factors depending on the wreck. If you want to get a rough estimate of how much to expect from a car accident settlement, add up your expenses for medical bills, car repairs and lost wages. Multiply that sum by three to five. The attorneys at Stoy Law Group have created a personal injury calculator to help you get an estimated settlement value for your car accident case.
