What is an example of future tense?

Answer 1

An example of future tense would be:

By the time he pays off his credit card debt, he will have run out of money. "Will have run" is the future tense.

ANOTHER ANSWER:

The verb "will have run" is not the future tense. It is the future perfect tense. Don't blame me, I did not make the English grammar rules. Not every verb that expresses some event happening in the future is the future tense. Unfortunately we have two tenses for future events. One is the plain vanilla future tense. The other is the Rocky Road style future perfect tense.

An example of Future Tense (plain vanilla) is:

"Nitpickers like the writer of this sentence will causemost people a lot of unnecessary grief, so avoid them in the future."

An example of Future Perfect Tense (rocky road) is:

If in the future you avoided nitpickers like the writer of this sentence, you will have saved yourself a lot of unnecessary grief."

Answer 2

An example of future tense is "She will go to the store tomorrow." In this sentence, the verb "will go" indicates an action that will happen at a later time.
