Which term describes a service that is offered at no cost?

The term that describes a service offered at no cost is "complimentary." This word suggests that the service is provided free of charge as a courtesy or as part of a larger package. For example, hotels often provide complimentary breakfast for guests, which means that guests can enjoy this meal without an additional fee.

Understanding why "complimentary" is used in this context helps clarify that it specifically indicates something is given as a favor or as included with a product or service, enhancing the overall value offered to the recipient. This practice can strengthen customer satisfaction and loyalty, as clients often appreciate receiving extras at no additional cost.

The other terms convey different meanings. "Chargeable" suggests that a fee is associated with the service. "Inclusive" usually refers to something that encompasses a range of services or items within a set price but does not necessarily imply that anything is free. "Exclusive" indicates that something is restricted or limited to a certain group, again highlighting that it is not a free service.
