Credit unions are typically nonprofit, Savings and loans are for profit, and initially operated for depositors, but over the past 30 years have made numerous loans to nondepositors.
Commercial banks are often privately owned, but my be listed corporately owned, and are not operated for depositors. They do not, to my knowledge, pay profits in dividends, but ownership interests may vary.
Mutual savings banks are the savings depositories that are owned by depositors and distribute profits/dividends among the depositors.
