Future Plans and Finished Future Actions
We can express general future plans with the verbs:
expect, hope, intend or plan and an infinitive.
• We hope to start putting some money away.
• I don’t plan to be financially dependent for the rest of my life.
Use the Perfect form of an Infinitive to express that an action will or might take place before a specified time period in the future.
• By this time next year, I plan to have saved up enough cash to buy a new car.
• Her goal is to have paid off all her debt in five years.
Future Perfect
Use the Future Perfect to indicate an action that will be completed by a specified time period in the future.
• By next year, I will have completed my studies, but I won’t have got married.
Use the Present Perfect in an adverbial clause to distinguish between a completed future action and one that will follow it.
• Once I’ve completed my studies, I’ll get married.
• I’m going shopping when I’ve finished my report.
Be careful: Don’t use the Future Perfect in the adverbial clause of time.
Wrong: I’m going shopping when I will have finished my report.
Correct: I’m going shopping when I have finished my report.
