"Prison Policy Initiative estimates that private prison corporations make about $374 million annually. To make a profit, private prisons charge the government a daily fee per inmate, which is often more expensive than the actual cost ($150 per day/inmate vs. $100 per day/inmate), according to Investopedia."
