1 Replacing a typical passenger car bumper can cost $100-$1,000 or more for just the bumper, depending on the year, make and model of vehicle; the material the bumper is made of; and whether the bumper was produced by the vehicle's original manufacturer (OEM) or is an aftermarket bumper made by other companies. Auto Parts Warehouse estimates that a basic steel chrome-plated bumper can cost $120-$1,000 or more, while a carbon fiber bumper might be $650-$5,000 or more.
