Lottery Net Lump Sum Payout Formula

Net Cash=(Jannuity×Rcash)×(1TFed, 37%TState)\text{Net Cash} = (J_{\text{annuity}} \times R_{\text{cash}}) \times (1 - T_{\text{Fed, 37\%}} - T_{\text{State}})

Net cash payout equals advertised jackpot multiplied by the cash option percentage, less top federal tax (37%) and applicable state income taxes.
