Future Perfect

Future Perfect is a verb tense used to talk about the future.  

It is like the other perfect tenses (present perfect, past perfect) because it uses a past participle.   

STRUCTURE 

Subject      +     Will (not)     +     Have      +      Past Participle

Examples:

• I will have finished work when you arrive.
  
• She will have eaten dinner by 7:00 pm.
  

USES Future Perfect is used for activities that are completed in the future before another future event.

Example:        

• Tom will have graduated University by the time Bob starts.
  

  (When Bob starts university, Tom will be finished.)


The other action is given in simple present.

Example:       

• I will have finished dinner when you arrive.
  

Remember the time of completion is important.

Examples:        

• I will take a graphic design class from July 10th - 28th.
  
• I will take a marketing course starting on August 1st.  
  
• I will have finished the graphic design course when I start the marketing course.                
  

The event in the future can simply be a time period.  “By” is often used in this situation.

Examples:        

• By 2050 scientists will have discovered a cure for cancer.
  
• I will have graduated high school by next year.
