60/40 split refers to a marriage or relationship dynamic where the man is the primary earner and the woman is the secondary earner. The man pays 60% of the bills while the woman pays 40% of the bills. Chores and childcare are split evenly and shared among the couple. Studies show the 60/40 split has the lowest rates of divorce, lowest rates of adultery, and highest rate of marital satisfaction. This is to be contrasted with the 40/60 split where the man pays 40% and the woman pays 60%.
