What do you mean by "it doesn't change a thing"? It can't ever get more than 100%. Below are: 1) $60k spending, $1.74m portfolio and 35 years and 2) same but with $50k SS starting in 2036. Both 100% but definitely different.
1) $60k spending, $1.74m portfolio and 35 years
2) $60k spending, $1.74m portfolio and 35 years with $50k SS starting in 2036
What I mean is, after adding SS and Pension, I should be able to reduce the Portfolio amount and still get 100%. I can't, after adding SS and pension, if I reduce the portfolio below $1.74M the success rate drops below 100%. It is odd, I don't know what I am missing I have used Fircalc several dozen times and not had any problem.
Another day, I will try again.
OK, maybe I am just expecting to much change with the SS and pension.
First I set Portfolio at $1,250,000 and spending at $60,000 and 35 years.
The result is 72.0%.
Now in the "Other Income/Spending tab, I enter $38,400 and $17,200 SS to start 2036 and $4,440 pension to start 2031 and Highlighting the circle for Pension Income.
Then hit submit, I do get a tiny change up to a 73.7% success.
Now I run to see the minimum portfolio for 100% success with spending at $60k for 35 yrs, I get $1,740,000. Then I add SS of $38,400 and $17,200 in 2036 and pension of $4440 in 2031. I then can reduce the portfolio to $1,703,000 before not having 100% success.
I'm leery that having $60,040 additional income for 20 of the 35 years does not reduce the needed portfolio more.
Still confused, must be me, but I'm trying.
