The cost depends upon the purchase price of the vehicle, the age of the vehicle, and the weight at which the vehicle will be registered in each jurisdiction. Estimated mileage is also part of the calculation. If you are a new registrant with no mileage history, there is a standard "average distance per jurisdiction”, which will be calculated for each vehicle. The average cost of an apportioned plate for a new vehicle, registered for 80,000 pounds for all jurisdictions, is $1,600-$1,800. For each renewal year, registration fees are based upon actual mileage driven and estimated mileage in added jurisdictions.
IRP, Inc. offers the Celtic Fee Estimator on line. The Celtic Fee Estimator is a tool to help you estimate the fees associated with registering apportioned vehicles based on various factors, including the distance associated with the jurisdictions traveled. This tool may be useful when you already have an established account.
