If you win the jackpot, you have two choices for your prize: a lump sum or an annuity, paid out over 29 years in 30 graduated payments. You can use an annuity calculator to estimate how much your money will grow over time. The cash option is a popular choice for lottery winners because it avoids taxes in the long run and allows you to invest in stocks and real estate. However, many lottery winners choose an annuity to receive their prize payments over a longer period of time.
