"She would be 80 when she died."

"She would be 80 when she died."

Is the sentence okay to use? I think "would be" should be "would have been" because it happened in the past and "would have been" is used for the past guessing What do you think? Thank you so much for your time and effort and help.

If you are talking about guessing how old someone was when they died then we would say "She would have been about 80 when she died", or "She was probably about 80 when she died" or even "I would say she was about 80 when she died".
