Future Perfect Continuous Tense (Future Perfect Progressive Tense)

The future perfect continuous tense is used much like the future perfect, but one of the actions is likely to continue beyond the other. It can also be used when one action will be continuing at a certain time in the future. Create the future perfect continuous this way: will + have + been + present participle (root + ‑ing). Look for key words like in and by.

In September, I will have been going to school for 4/5 of my life.

By 2015, you will have been living in Mexico longer than you’ve lived anywhere else.

By the end of this month, she will have been working long enough to get benefits.

In three months, they will have been seeing each other for a year.

Remember not to use the future perfect continuous tense with non-action verbs like be, seem and know. These verbs should use the future perfect.

Tomorrow, I will have been being here for a week.
