On 2/7/2019, the Powerball was listed at $224 million. The “cash value” was listed as $136.4 million (this is the lump-sum immediate payment option). If you choose the annuity option, you’ll receive the $224 million in 30 equal installments, with the first payment immediately. If your interest rate is 5%, which option should you choose? What if it’s 3%?
interest rate at 5%
PV of annuity option
PVAnnuity Due = c*((1-(1+ i)^(-n))/i)*(1 + i ) |
C = Cash flow per period |
i = interest rate |
n = number of payments |
PV= 7.46666666666667*((1-(1+ 5/100)^-30)/(5/100))*(1+5/100) |
PV = 120.52 |
choose lumpsum option as it has higher value of 136.4 mln
interest rate at 3%
PVAnnuity Due = c*((1-(1+ i)^(-n))/i)*(1 + i ) |
C = Cash flow per period |
i = interest rate |
n = number of payments |
PV= 7.46666666666667*((1-(1+ 3/100)^-30)/(3/100))*(1+3/100) |
PV = 150.74 |
this time choose annuity option as it has higher PV than lumpsum option
