There are two main ways that lottery promoters make their money. They can charge for tickets and collect the money that is paid in, or they can make their profits on the difference between the ticket prices and the odds of winning. Both of these methods have advantages and disadvantages, and the choice between them depends on the type of lottery that is being conducted.

In a traditional state-run lottery, the total value of the prizes is the sum of all the ticket sales less the cost of production and promotion.
