The future perfect consists of two verbs: helping verb (will have) and main verb (past participle).
will have + past participle = future perfect
The future perfect takes place before another action in the future.
Examples:
When you get this message I will have left for New York.
I hope that I will have finished my work before the weekend.
By the end of the month, she will have completed the English course.
We form the negative by adding not between the helping verb will and have.
will + not + have + past participle
will not = won’t
Examples:
Simon will not have arrived before 8 pm tonight.
By the end of this month I won’t have completed this project.
