Edited by Janet White || By Aimie Carlson || Published on November 27, 2023
"Will be" indicates a future state or condition, while "will have" denotes a future possession or completion of an action.

Key Differences

"Will be" is used to express a future state of being or condition, indicating what someone or something will become or how they will exist in the future. In contrast, "will have" is used to show possession, completion, or attainment of something in the future.
When using "will be," the focus is on the future status or condition of the subject. For example, "She will be a doctor" highlights the future profession of the subject. On the other hand, "will have" emphasizes the acquisition or completion of something, as in "She will have completed her degree."
"Will be" often precedes an adjective or a noun to describe the future state, like "The weather will be sunny." Meanwhile, "will have" is usually followed by a past participle to indicate a future action that will have been completed, such as "He will have finished the report."
In terms of grammar, "will be" is the future tense form of "to be," reflecting a continuous or permanent state in the future. Whereas "will have" is the future perfect tense, suggesting a sense of completion or achievement by a specific future time.
"Will be" can be used for predictions, future plans, or expectations about the state of things. In contrast, "will have" is used for actions that will be completed by a certain future point, or when talking about future possessions or experiences.
