Explanation:

A surcharge is an extra fee, charge, or tax that is added on to the cost of a good or service, beyond the initially quoted price. Often, a surcharge is added to an existing tax and is not included in the stated price of the good or service. The charge could reflect a locality's need to collect money for extra services, a hike to defray the cost of increased commodity pricing, such as with a fuel surcharge, or an extra fee on your wireless bill for access to emergency services.
