Willie Keith · Answer 1

PV = P (1 - (1 + r) ^-n) / r; where P is the periodic withdrawal = $100,000; r = rate = 5% = 0.05; n = number of periods = 20 years.

PV = 100000 (1 - (1 + 0.05) ^-20) / 0.05 = 100000 (1 - 1.05^-20) / 0.05 = 100000 (1 - 0.3769) / 0.05 = 100000 (0.6231) / 0.05 = 100000 (12.4622) = 1,246,221 ≈ $1,250,000
