Some writers           the years in detail, as follows:

Abraham became the father of Isaac, when he was 100 years old
Isaac became the father of Jacob, when he was 60 years old
Jacob became the father of Levi, when he was 86 years old
Levi became the father of Kohath, when he was 46 years old
Kohath became the father of Amram, when he was 63 years old
Amram became the father of Moses, when he was 70 years old
Moses led the people out of Egypt, when he was 80 years old
So the total length of time, from the first year of Abraham until the exodus from Egypt, is 505 years.
