Been doing some figuring (Spaf math)
You gotta love the TSP program!
Using TSP, if you saved right, you should be able to retire and withdraw 4% or less annually.
Now the G-fund (the Lilly Pad) will replace the 4%.
So in a bear market you will survive.
In a bull market you need to off set inflation. Really your trading for a COLA.
Following tsptalk minimum investment: risk v reward; 50% (G/F) and 50% (C/S/I). You should be able to pick up the COLA at minimum risk, following the leaders on the MB at 50% of their risk.
Granted anytime in stocks there is a risk!
Maybe "rokid" could better analyze the probability factors.
However, it seems to me that TSPTalk members have a great advantage to manage their funds sucessfully, especially in retirement.
Just MHO!
Reards....and be careful!....
