While there are many factors that determine the advertised Grand Prize estimate in the Powerball® game; two important ones are games sales and the annuity factor.

A number of variables can affect game sales, such as seasonality or a big Mega Millions jackpot. Traditionally, game sales are stronger for a Saturday drawing versus a Wednesday drawing.

The annuity factor, or the cost to fund an annuity prize, is another key component. The annuity factor is made up of interest rates for securities purchased to fund prize payments. The higher the interest rates, the higher the advertised Grand Prize. You might not realize that an economic reality like interest rates impact even the Powerball jackpot, but they do!
