What is the most number of times a president can be elected?

A U.S. president can be elected to a maximum of two terms, totaling four years per term, as established by the 22nd Amendment to the Constitution. This means the most a president can serve is eight years in office. However, if a president assumes office through succession and serves less than two years of a term, they can run for two additional full terms, potentially allowing for a maximum of ten years in total.
