Total money will be transferred to saving account afte 23 years = $159,453.35 + $1,433,241.72 + $1,872,314.03
= $3,465,009.10
Now this money will be invested in saving account at 3% interest rate and every year couple withdraw equal amout say a at the beginnig of year so that in 25 years balance in saving account will be zero.
Therefore
Yearly withdrawl = $3,465,009.10 / Cumulative pv factor for 25 period of immediate annuity at 3%
= $3,465,009.10 / 17.93554212 = $193,192.33
Therefore yearly withdrawl amount comes at $193,192.33
