On average though the annual cost of car insurance for a 25 year old male in the United States is around $900.00 to $1,000.00
You can go on insurance companies websites and get an auto insurance quote to find out a more accurate cost as to what it might cost you because it will depend on the State you're in, the type of vehicle you drive and the value of the vehicle as to what your insurance cost will be.
