The numbers behind everyday driving
Most car costs are invisible until it's too late. True cost of car ownership rolls depreciation, fuel, insurance and maintenance into one annual number so you know what each mile actually costs. Before you buy, the car loan calculator shows the monthly payment and total interest you'll pay over the life of the loan — and stopping distance is a good reminder of how much extra following distance wet or icy roads really need.
