What is the average age for a giant star?

Giant stars typically have relatively short lifespans compared to smaller stars, with their average age depending on their mass. Massive giants can live only a few million years, while less massive giants may last tens of millions of years. Generally, giant stars are in a later stage of stellar evolution, having exhausted their hydrogen fuel and expanded after entering the red giant phase. Thus, their ages can range from around 10 million to a few hundred million years.
